Natural selection and the peppered moths
Download as DOCX, PDF4 likes35,172 views
Natural selection led to changes in the coloration of peppered moths over time. An animation showed that in a dark forest, 53% of moths were dark while 47% were light, as dark moths had better camouflage from predators. In a light forest, most moths were light. Natural selection occurs as moths with colors that make them more visible to predators are eaten, while others survive and pass on their genes.

This chapter discusses heat transfer through conduction, convection, and radiation. It begins by explaining convection as the transfer of heat by the bulk movement of fluids such as occurring in hot water baseboard heating. Conduction is defined as the transfer of heat through direct contact between particles via collisions. The rate of conduction depends on properties like thickness, area, temperature difference and thermal conductivity. Radiation is the transfer of heat via electromagnetic waves and follows the Stefan-Boltzmann law. The chapter covers applications of heat transfer principles like insulation and cooking stoves.Ideal Gas Law
Ideal Gas LawDemereeVicente

The ideal gas law, also referred to as the general gas equation, is the equation of the state of the imaginary ideal gas. It is a good approximation of the behavior of certain gasses under several circumstances, although it has many drawbacks. It was first mentioned by Beno樽t Paul mile Clapeyron in 1834 as a synthesis of the empiric law of Boyle, the law of Charles, the law of Avogadro, and the law of Gay-Lussac.Describing matter

This document defines key terms related to matter: matter is anything that has mass and takes up space. A pure substance has a specific, unchanging makeup like salt or sugar. Matter has physical properties that can be observed without changing its substance, like melting point, and chemical properties that describe its ability to change into other substances through reactions. Elements are pure substances that cannot be broken down further, while mixtures contain two or more substances that are not chemically combined. Mixtures can be homogeneous, where the parts are evenly mixed and not visible, or heterogeneous, where the different parts can be seen.qtr week 2.pptx

The document summarizes several gas laws including Boyle's law, Charles' law, and Gay-Lussac's law. It explains that these laws describe the relationships between various gas properties including pressure, volume, and temperature. The document also introduces the key scientists associated with each gas law and provides the mathematical equations to represent each relationship. Finally, it discusses how the individual gas laws can be combined into the ideal gas law, which relates the pressure, volume, amount, and temperature of a gas.The Ideal Gas Law

The document discusses the ideal gas law PV=nRT and its application to real gases. It defines the four variables in the equation, describes how the ideal gas law relates these variables, and explains how to derive the gas constant R. While real gases deviate from ideal behavior, the ideal gas law can still adequately describe gases at low pressures and temperatures near room conditions. Two examples are given applying the law to calculate pressure and temperature for gas samples.Mass and weight
Mass and weightDeepaliSakundeJadhav

Mass is a quantity that remains constant regardless of location, while weight is the gravitational force exerted on an object that can change depending on location. Common tools for measuring mass include balances that use springs or electronics, while the formula for calculating weight is weight = mass x gravitational acceleration. Gravity and therefore weight vary on different celestial bodies, so an object's weight would be lower on the Moon but higher on Jupiter compared to Earth.Enthalpy Hess's Law
Enthalpy Hess's LawLumen Learning
油
Hess's law states that the enthalpy change of a reaction is independent of the pathway taken and depends only on the initial and final states. Hrxn is calculated by adding individual reaction enthalpies that convert reactants to products. For example, if reaction A is A B with H = x kJ and reaction B is B C with H = y kJ, the direct reaction A C has H = x + y kJ by Hess's law. Hess's law allows calculating enthalpy changes for complex reactions by summing enthalpies of simpler constituent reactions.Melting, Freezing, Boiling points

There are five states of matter: solid, liquid, gas, plasma, and Bose-Einstein condensate (BEC). Plasma is common among stars but not on Earth, while BEC only forms at extremely low temperatures near absolute zero when atoms lose kinetic energy and clump together. Gases are characterized by diffusion, the movement from high to low concentration, and effusion, movement through a small pore. Several gas laws describe gas behavior, including Boyle's law relating pressure and volume, Charles' law relating volume and temperature, Avogadro's law of equal volumes containing equal molecules, and Dalton's law of partial pressures.

The document discusses key concepts in thermodynamics and thermochemistry including:
1) Thermochemistry is the study of energy changes that occur during chemical reactions. Reactions can be exothermic, releasing heat from the system, or endothermic, absorbing heat into the system.
2) The enthalpy change (H) of a reaction indicates whether it is exothermic (negative H) or endothermic (positive H).
3) A system exchanges energy with its surroundings during chemical or physical changes. Exothermic reactions increase the temperature of the surroundings while endothermic reactions decrease it.Evolution -the peppered moth presentation student version

The document describes how the Peppered Moth evolved through natural selection. Before the Industrial Revolution, most Peppered Moths were light in color to camouflage themselves on light-colored trees. A small number were dark. During the Industrial Revolution, pollution from factories darkened tree bark. This caused dark Peppered Moths to better camouflage while light ones were more visible to birds. Over time, more dark moths survived to reproduce, causing that variety to become more common through natural selection based on environmental changes.C13 Peppered Moth

The document describes how the color variations of peppered moths in England adapted to changes in their environment due to the Industrial Revolution and pollution. Peppered moths exist in both light and dark colors. Before industrialization, most tree trunks were light in color due to lichen growth, giving dark moths a disadvantage as they were more visible to predatory birds. After industrialization blackened the tree trunks, dark moths had better camouflage and survival rates increased while light moths were more vulnerable to birds. Experiments showed natural selection was occurring as the moth population colors shifted depending on the tree colors in their habitats.Evolution -the peppered moth presentation teacher version

The document discusses evolution through natural selection using the example of the peppered moth. Before the Industrial Revolution, light-colored peppered moths were more common as they could camouflage on light-colored trees. Darker moths stood out and were more likely to be eaten by birds. During the Industrial Revolution, pollution from factories darkened tree bark, causing darker moths to blend in better while light moths were more visible and their numbers declined. This showed how environmental changes can cause natural selection to favor different varieties of a species over time, leading to evolution.Theory of Evolution

Darwin proposed the theory of evolution by natural selection, with four main ideas: 1) Common descent, that all organisms are related through descent from a shared ancestor, 2) Gradualism, that new species arise gradually through accumulation of adaptations, 3) Multiplication of species, whereby gradual changes lead to diversification, and 4) Natural selection, the mechanism by which organisms better adapted to their environment are more likely to survive and produce offspring.Evolution Power Point

Charles Darwin developed the theory of evolution by natural selection based on his observations during a voyage aboard the HMS Beagle. He noticed variations between species on different islands that helped some individuals survive and reproduce more than others. Over generations, beneficial variations became more common in populations through the natural selection process. Evolution can occur gradually over a long period of time or in short bursts through punctuated equilibrium. The fossil record, homologous and vestigial structures, and similarities in DNA provide evidence that evolution has occurred.Evolution powerpoint

It provides examples of how bacteria can gain antibiotic resistance genes from other bacteria through bacterial conjugation, transformation, or transduction rather than the genes evolving de novo. This challenges the idea that antibiotic resistance in bacteria is evidence for evolution, as the genes may have always existed in other bacteria and were transferred rather than created by evolution.Darwin and evolution_part_1 (1)

Darwin's observations of animals in South America and the Galapagos Islands led him to form ideas about evolution. He noticed that related species on the different islands had adaptations suited to their local environments. This helped Darwin develop his theory of natural selection, where organisms better adapted to their environment are more likely to survive and pass on their traits, leading to evolution over generations as populations adapt to their surrounding conditions.5.4 Natural Selection (by Jane Choi)

Natural selection is the process by which organisms with traits that better suit their environment tend to survive and pass on those traits, while organisms with less advantageous traits tend not to survive or reproduce. Charles Darwin observed that organisms vary, some are better adapted to their environment, and these better-adapted organisms are more likely to survive and reproduce, passing on their favorable traits. Over generations, this leads to changes in the characteristics of populations and evolution of species as the proportion of individuals with beneficial traits increases.Darwin natural selectionnotes

Evolution is the process of change over time. Charles Darwin proposed natural selection as the mechanism of evolution. Natural selection occurs in four steps: overproduction of offspring, variation among individuals, competition for limited resources that results in survival of the fittest, and adaptation of traits that increase survival. Evidence that supports the theory of evolution includes the fossil record, homologous structures, vestigial organs, embryology, and biochemical comparisons.Evolution- Laila Bangwar & Lujane Pagganwala

Natural selection is the process by which organisms with traits that help them survive and reproduce in their environment become more common over generations. When resources are limited, competition arises between organisms. Those with useful adaptations, like camouflage, are more likely to live on and pass their traits to offspring. Over time, natural selection leads populations to become dominated by organisms with adaptations suited to the environment.Evolution of antibitics resistance1

Natural selection occurs in nature when heritable traits influence the survival and reproduction of organisms over generations, such as brown beetles flourishing while green beetles were selected against. Artificial selection is when humans intentionally breed organisms with desired traits, such as farmers choosing to breed green beetles as their favorite color. The key difference is that natural selection is an unguided process in nature whereas artificial selection involves intentional human choice.Blood Cell

1. Natural selection requires variation within a population, a struggle for survival, and differential reproduction.
2. Variation arises through mutations during DNA replication, meiosis, sexual reproduction, and viral infection. During struggles for survival, individuals with adaptations that allow them to compete better for food, mates and living space are more likely to survive and reproduce, passing on their traits.
3. Over time, natural selection can act on variations to change the characteristics of a population as better adapted traits become more common through reproduction.Evolution natural selection

This document provides an overview of a game that teaches players about evolutionary trees and DNA. It demonstrates how the game allows players to place different animals on an evolutionary tree based on DNA similarities. Sample levels are proposed that start broadly and become more specific. Short educational modules are also outlined to teach players key concepts like what DNA is and how mutations accumulate over generations. The goal is to create an engaging and educational game to help players understand evolutionary relationships.Trickster tales presentation

Trickster tales are short stories, originally told orally, that feature animal characters who act like humans. They usually involve a weak character outwitting a stronger enemy through cleverness or intelligence. Trickster tales aim to teach a moral lesson and reflect the culture in which they originated. They involve a problem and solution and are told from a third-person point of view.The function of body colouration of the ladder-web spider Herennia multipuncta

1. The document examines the potential functions of body coloration in the ladder web spider Herennia multipuncta.
2. Field experiments show that the orange dorsal coloration attracts more diurnal prey while both orange and gray colors together attract more nocturnal prey.
3. Manipulative experiments indicate that spiders with conspicuous ventral coloration received less attacks from lizards and had longer latency times, suggesting the coloration functions in anti-predator defense.More from lauris13 (7)

- 1. Natural selection and the peppered moths I. Enter to the following website and read all the slides containing information about the peppered moths: http://www.techapps.net/interactives/pepperMoths.swf 1. Play the animation of A bird卒s eye view of natural selection in dark forest and light forest. Record the percentage of moths (dark and light) in each type of forest in the following table at the end of the animation. % Dark moths % Light moths Light forest 36 64 Dark forest 53 47 2. Explain how the color of the moth increases or decreases its chances of survival depending on the color of the trees. In the dark forest is easier to a predator to eat the light moths because the trees are dark and the light moths are easier to see. In the light forest is easier to a predator to eat the dark moths because the trees are light and the dark moths are easier to see. 3. Explain the concept of natural selection using moths as an example. A moth had a mutation in his DNA and he pass it to his offspring, sothey start turning darker than they were and the dark moths take advantage in the dark forests. 4. Imagine there were no predators in the forest. Would the colors of the moths change over time? Support your answer No, because there卒s no need to change of color if there is not predators.
