Is a reflex part of the central
nervous system, the peripheral
nervous system, or both? Explain.

Answer:Because the peripheral nervous system transmit reflex impulses from sense organs to central nervous system and then back to the sense organs. So both the Central nervous system and the peripheral systems are involved.
To understand a bit better.....
One of our body parts consists of a nervous system it is a complex network of neurons and cells that carry pieces of information to and from the brain and spinal cord to various parts of the body.
So in conclusion...
Yes! The Central nervous system and the peripheral systems are involved!So therefore your question is correct!

A biologist reads an article in a scientific journal that describes how the legs
of different organisms look and function differently, but appear to be
constructed from the same basic bones. He compares a drawing of the
skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)
What aspect of the theory of evolution do these drawings support?
Answers
Answer:
Homology
Explanation:
The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.
Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.

Which statement best describes codominance and incomplete dominance?
Answers
Answer:
This question lacks options, the options are;
A) In codominance and incomplete dominance, both of the alleles are dominant.
B) In codominance and incomplete dominance, neither of the alleles are dominant.
C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.
D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.
The answer is C
Explanation:
Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.
- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.
- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.
