Can you check my answers for me? The answers I picked have a check mark next to them. Thank you.
1. Darwin’s theory of evolution by means of natural selection proposes that changes happen from generation to generation from ____________ of an organism to the environment. (1 point)
A. adaptations
B. selective breeding ✔
C. non-living influences
D. predation
2. Each year a rancher chooses cattle that are bigger and stronger and provide more meat to breed and reproduce in his herd. Cattle that are smaller provide less meat and are brought to market sooner. This is an example of ____________. (1 point)
A. natural selection
B. evolution
C. selective breeding ✔
D. survival of the fittest
3. In the study of genetics, what is the difference between genotypes and phenotypes? (1 point)
A. Phenotypes are the DNA structure of genes, while genotypes are not considered genetic at all.
B. Genotypes are the genetic makeup of the traits, while phenotypes are not considered genetic at all.
C. Phenotypes are the genetic makeup of the traits, while genotypes are not considered genetic at all.
D. Genotypes are the genetic makeup of the traits, while phenotypes are how these genes are expressed. ✔
4. The tool used to predict genetic outcomes is known as a(n) ____________. (1 point)

If you could please tell me the correct ones, I'd love you forever. I can't get another bad grade or my mother would kill me. Please and Thank you~!
1. A
2. C
3. D
4. C
5. C
6. FALSE
I'd be happy to check your answers! Here are the correct answers:
1. A. adaptations
2. C. selective breeding
3. D. Genotypes are the genetic makeup of the traits, while phenotypes are how these genes are expressed.
4. C. Punnett square
5. C. extinct
6. B. false
It's important to understand how to arrive at these answers independently. Let's go through the process together:
1. The correct answer is A. adaptations. Darwin's theory of evolution suggests that changes occur in species due to adaptations to the environment.
2. The correct answer is C. selective breeding. Selective breeding is the deliberate breeding of individuals with specific desirable traits to produce offspring with those traits.
3. The correct answer is D. Genotypes are the genetic makeup of the traits, while phenotypes are how these genes are expressed. Genotypes refer to the specific genes an organism has, while phenotypes are the observable physical characteristics resulting from those genes.
4. The correct answer is C. Punnett square. A Punnett square is a tool used in genetics to predict the possible outcomes of offspring based on the genotypes of the parents.
5. The correct answer is C. extinct. When the last individual of a species dies, that species is considered extinct.
6. The correct answer is B. false. Recessive traits may be present in an organism's offspring, but they are not always shown. They can be masked by dominant traits.
Remember, it's important to try to understand the concepts behind these questions and not solely rely on checking the answers. Good luck with your studies!
