Answer:
From the research I did, I believe the answer is A.
Explanation:
I really hope this is helpful c:
1. <span>tRNA is the one carrying amino acids
2. </span>Mutation does not always affect the evolution of a species because <span>not all mutations affect an entire species.
3. </span><span>The type of chromosomal mutation that occurs here is an example of a deletion mutation. Specific genetic data, or DNA is removed and the remaining portions of chromosomal information have rejoined.
4. </span><span>A chromosomal deletion mutation
5. </span>The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to a gene that makes a DNA repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.
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>
