Energy can exist in multiple forms including mechanical, light, sound, thermal, electrical, chemical, and nuclear. It can be renewable sources like water, wind, sun, biomass, or waves and tides, or non-renewable sources like fuels or uranium and plutonium. Our bodies transform the chemical energy from food into mechanical energy for movement. Electricity is a form of energy that can be easily transported through power lines and transformed into other types of energy like light. Static electricity occurs when an object accumulates an electrical charge, which can be neutral, positive, or negative. Electrical current is the movement of electrical charges through a conducting material. Producing and using electricity can cause problems to the environment likeUnit 2 nutrition david

We eat food to obtain nutrients and vitamins that our bodies need, and our digestive system extracts these substances. In addition to digestion, respiration or breathing is also part of nutrition by providing oxygen. The circulatory system is essential for nutrition as it transports the nutrients we eat and oxygen we breathe to our organs, bones, brain, and muscles. Our blood contains three types of cells that each perform specific functions. Vitamins are essential nutrients our bodies need. Junk food contains high levels of sugar and fat, and if consumed in excess can accumulate in our bodies, causing weight gain and potential illness.Unit 1 interaction alvaro s

The nervous system has three main parts: the brain, spinal cord, and nerves. The brain receives information and sends messages to the body via the spinal cord and nerves. The brain is made up of the cerebrum, cerebellum, and brainstem. Neurons are the basic building blocks of the nervous system and are composed of axons, dendrites, and a cell body. The five senses - sight, hearing, touch, smell, and taste - allow us to perceive the world around us. Each sense has specialized sensory organs that detect stimuli and relay this information to the brain via nerves.Unit3 nutrition monica s

Nutrients provide cells with energy and four body systems work together to carry out nutrition: the digestive system breaks down food and absorbs nutrients, the respiratory system inhales oxygen and exhales carbon dioxide for cellular respiration, the excretory system filters waste from the blood and removes it from the body through sweat and urination, and the circulatory system transports blood to circulate nutrients and oxygen to cells and remove waste.Unit 3 nutrtion tomas s

Human reproduction involves the joining of male and female sex cells through sexual reproduction. The primary sexual characteristics are the reproductive systems which differ between males and females and are present at birth. Fertilization occurs when an ovum and sperm join inside the fallopian tubes to create a single cell called a zygote, which implants in the uterus wall and becomes an embryo, leading to pregnancy and culminating in labor and birth.Unit 3 nutrition clara s

The document summarizes the key functions of the digestive, respiratory, excretory, and circulatory systems. It describes how nutrients are broken down and absorbed in the digestive system and carried via the blood. It explains that the respiratory system intakes oxygen and removes carbon dioxide. The excretory system filters waste from the blood through sweat glands and the urinary system. The circulatory system transports blood, nutrients, oxygen, and waste throughout the body using the heart, arteries, veins, and capillaries.Human reproduction by Yulia

The document provides an overview of the human reproductive system and process of reproduction. It describes the male and female reproductive cells and systems, including the testes, ovaries, uterus and other organs. It explains fertilization occurs when an egg and sperm join in the fallopian tubes. Pregnancy involves development of the embryo and fetus over 9 months as it is nourished through the placenta. Labor concludes pregnancy in three phases as contractions widen the birth canal for delivery of the baby.Unit 4 human reproduction teresa s

The document summarizes the human reproductive system. It describes that reproduction allows living things to create offspring similar to themselves. It then outlines the primary and secondary sexual features that characterize the male and female reproductive systems. The reproductive cells, ovaries, uterus, vagina, vulva, fallopian tubes, testicles, vas deferens, urethra, penis, seminal vesicles and prostate are defined. Fertilization is defined as the union of sperm and ovum in the fallopian tubes, and menstruation occurs if the ovum is not fertilized. The development of an embryo is described including the placenta, umbilical cord, and amniotic sac.Unit2 sensitivity and coordination noemi and clara s

This document discusses the human senses and nervous system. It describes the organs of sight, smell, hearing, touch, and taste, as well as stimuli, responses, neurons, voluntary and involuntary movements, the skeleton, joints, musculature, and tendons. The nervous system is made up of the central nervous system including the brain and peripheral nerves. Neurons are specialized cells that transmit signals in the nervous system. Voluntary movements are controlled by the brain while involuntary movements are controlled by the spinal cord. The skeleton is composed of bones in the head, trunk, and limbs connected by ligaments and joints. Muscles are attached to bones via tendons and located in the head, trunk, and limbs.Unit 5 energy alberto s

Human reproduction involves the joining of male and female sex cells. During puberty, individuals develop primary and secondary sex characteristics that differentiate males and females for reproduction. The female reproductive system includes ovaries, uterus, fallopian tubes, vagina, and vulva. The male system includes testes, vas deferens, urethra, seminal vesicles, and prostate. Fertilization occurs when sperm joins an ovum in the fallopian tubes. The fertilized egg implants in the uterus and develops over nine months into a fetus with a placenta and umbilical cord, until birth through labor in three stages of dilation, expulsion, and afterbirth.Human reproduction by Julia

Human reproduction occurs through sexual reproduction. During puberty, between ages 11-15, secondary sex characteristics develop in both males and females to differentiate the sexes. The male reproductive system produces sperm in the testes which are transported through the vas deferens and urethra. The female reproductive system contains ovaries that produce eggs and a uterus for fetal development. Fertilization occurs when an egg and sperm join in the fallopian tubes to create an embryo. Pregnancy lasts around 9 months as the embryo develops structures like the placenta and umbilical cord to receive nutrients until birth.Christmas fun lucia villacorta s

All the good fairies in attendance blessed Rose with gifts, but the final fairy had not been invited. She cursed Rose to prick her finger and die on her 16th birthday. Another fairy softened the curse so that Rose would instead fall into a deep sleep for 100 years. On her 16th birthday, Rose pricked her finger and fell asleep along with the entire kingdom for 100 years. A brave prince eventually found and woke Rose with true love's kiss, and they married, breaking the curse and living happily ever after.Unit 4 human reproduction claudia lucia and teresa s

Santa Claus was a carpenter who lived at the North Pole with his wife. As they did not have children of their own, Santa enjoyed making wooden toys but was concerned that children couldn't play outside when it was cold and snowy on Christmas. His wife came up with the idea of Santa delivering the toys to children in their village on Christmas Day. Although Santa did this for many years, one particularly snowy Christmas threatened to prevent him from reaching all the children. An angel then gave Santa magic reindeer, a red sleigh, a red coat, and some elves to help deliver all the toys, allowing Santa to continue bringing presents to children everywhere even in heavy snow.Ad
