Answer:
1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.
2. Fossil evidence: organisms changing form over time through the fossil record.
Direct observation. We can directly observe small-scale evolution in organisms
with short lifecycles (e.g., pesticide-resistant insects).
Explanation:
The following are the two conclusions that Morgan made about qualities and chromosomes:

I hope the answer will help. Feel free to ask more questions in brainly.
The very primitive organism is the oldest because, over time, organisms gradually evolved into more complex organisms. First came the primitive organism, then it evolved into the more complex one, or the younger fossil.
Answer:
The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:
a. The adrenal cortex is an extension of the parasympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Explanation:
The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.
Answer:
b. false
