Weekly Blog Post - "Evolution Lab(s)" (10|9|17-10|15|17)

Summary: During this week, my class did two labs--one was on mutations and the other was on natural selection. While completing this labs, I learned that a mutation is a change in DNA and that harmful mutations are called "lethals". 

SP1: Asking questions and defining problems. I asked scientific questions when we were completing the lab such as, "Would it be possible for one breed to have a special mutation, inter-breed with another and then pass on that mutation, or would it be a recessive gene, with the  chances of being passed on to the offspring being very low?"

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

                                                                                      Here is the citation of the picture:  The Volcano                                                                                                       Weekly Blog (9/14-9/21) Summary: One thing we did this week was make a paper mache volcano. A volcano is a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.  SP8: This week our class discussed 'the rock cycle.' The rock cycle is a cycle where different types of rock turn into another type of rock. Metamorphic rock melts and becomes magma. Then it comes up a volcano and cools. This new rock is an igneous rock. The igneous rock weathers or erodes and becomes sedimentary rock. The sedimentary rock heats up and turns into metamorphic rock. Then the whole cycle starts all over again.
