Weekly Blog Post - "Evolution" (10|30|17 - 11|6|17)

Summary: During this week, I learned about scientists could use comparative analogy and homologous structure to compare two species to find out a common ancestor. I also learned that caimans had five toes and that a caiman hatches from an amniotic egg. Another thing that I learned this week was that an amniotic egg was an egg filled with fluid laid on land to help the developing embryo.

 SP1: Asking questions and defining problems. I asked questions when we were completing our "Who is the Closest Relative to the T-rex?" such as, "Is it possible that the T-rex might have hair?" I asked more questions like, "What was the hide of a T-rex like? Was it rough, like an elephant's? Or scaly, like a crocodile?"

The Circulatory (Cardiovascular) System

Image
The Structure & Function: What is the function of the circulatory system?   The job of the circulatory   system works on circulating blood, lymph, nutrients, oxygen, other gasses, and hormones throughout the body, hence the name circulatory system. The circulatory system also balances temperature and pH balance while protecting the body from diseases. The circulatory system consists of the heart, blood vessels, blood, lymph, and the lymphatic glands & vessels. https://s3.amazonaws.com/classconnection/128/flashcards/8043128/png/insideheart1328771781022-14DEA48509547B9E19F.png What are the names and functions of the major organs in the circulatory system?  The names & functions of the major organs in the circulatory system are... Heart (cardiovascular): The heart is an organ that pumps blood through the body, providing oxygen & nutrients to the tissues (such as muscles). The heart also works on removing carbon dioxide and other unwanted wastes (whi

The Renal (Excretory, Urinary) System

Image
The Structure & Function:  What is the function of the renal system? The function of the renal system is the eradication of wastes manufactured by homeostasis (this word comes from two combined words in Greek: "homeo" meaning similar, & "stasis" meaning stable). The organs that are used in this process are the lungs, the liver, & the kidneys. What are names & functions of the major organs in the renal system? The names & functions of the major organs in the renal system are... Kidneys: the kidneys are organs that receive the waste from the body. The kidneys then percolate things from the waste, such as salt, urea, & excess water which is disposed from the body as urine. Skin: The skin executes its function through sweat glands. Sweat is used to cool us off as well as to get rid of unwanted oils, salt, water, and other gratuitous elements that ooze from small pores in the skin. Lungs: The lungs, an important organ in both th

10/24 Interdependence of Organisms

Image
              Interdependence of Organisms The interdependence of organisms is when organisms depend on each other for food to survive. Their whole reason to survival is so that they can live long enough to reproduce.  Backward Looking - Reflection: If an animal disappears from the rainforest then the animal who depends on this dying species for it's survival will also die due to lack of food. And so on and so on. Also it will affect the animal/plant that it does eat, meaning if the humming bird disappears from the rainforest or other biomes it will affect flowers or other plants, meaning they will over populate or under populate and that biome/rainforest will not have a healthy balances of plants and animals. Inward Looking - Reflection: I liked the work that I did this week because I could understand all the animals and the food chains/webs. I also liked it because of the fun activities that we did.I liked it because instead of using everyday textbooks, we get to google thi
