Answer:
The theory of natural selection was proposed by Charles Darwin, which states the mechanism of biological evolution by explaining <u>adaptation and speciation.</u> There was five observation of the theory of natural selection.
1) The population produces more offspring than there are adults, in each generation.
2) The population does not continue to grow in size.
3) Food and many other resources are limited.
These three observations interfere that individuals compete for resources within a population.
4) Individuals within all populations vary.
5) Many variations are heritable.
He also assumed from these two observations that individuals inherit some characteristics that give a better chance of surviving and reproducing.
These observations and interpretations helped him to propose the theory of natural selection. The theory tells the <u>heritable characteristics in a population change over time</u> <u>become more adapted in generation after generations.</u>
Answer:
Yes.
Explanation:
Bacteria are the simplest of creatures that are considered alive. Bacteria are everywhere. They are in the bread you eat, the soil that plants grow in, and even inside of you. They are very simple cells that fall under the heading prokaryotic. You don't usually get infected by dead bacteria, because They get recycled. Unlike larger organisms, when single-celled organisms die, they usually undergo a process called lysis, in which the cell membrane disintegrates.
A species must be able capable of surviving and reproducing despite changes to food sources, climate, or threats from predators.
It has made insulin cheaper and more readily available most likely improved the lives of diabetics
<u>Explanation:</u>
Ineffectual composition of the hormone recognized as insulin leads to an issue termed diabetes. Insulin permits the body's cells to consume glucose, which they utilize as food. Demand to discover a method to generate huge amounts of insulin economically raised when the number of crises of diabetes extended to rise. Genetic engineering procedures provide microorganisms for this plan.
Diabetes victims have to infuse insulin to regulate their blood sugar levels. A variety of insulin from yeast and bacteria like E. coli has been designed by Genetic engineering. This genetically mutated insulin, ‘Humulin’ was authorized for human application in 1982.
