C is this answer because they are both dominant and the same
Answer: unconformity
Explanation: I took the test.
Sixty-five million years ago, more than three-fourths of all plant and animal species living on Earth becameextinct<span>. This event is known as the </span>K-T<span> mass </span>extinctionbecause it occurred at the boundary between theCretaceous<span> (K) and Tertiary (T) time periods. The most famous group of animals to perish was the dinosaurs.

Answer: Because epinephrine activates the fight or flight response, related to the sympathethic response in the body.
Explanation:
The function of the Autonomic Nervous System is the regulation of the system cardiovascular, digestion, respiration, body temperature, metabolism, exocrine glands, and therefore keep the internal environment constant (homeostasis). While sympathetic activity increases in stress, the activity parasympathetic predominates during rest and satiety. The adrenal medulla originates from the neural crest and is composed of neuroendocrine specialized cells and are responsible for the production of catecholamines.
Catecholamines are dopamine, adrenaline, and noradrenaline (epinephrine and norepinephrine). Epinephrine prepares muscles, lungs, and heart for more intense activity, in situations of stress. It promotes the increase in the force of contraction in the muscles and increases in the heart rate. It also leads to increased blood pressure and bronchodilation, for greater availability of O2.
Answer:
population = 600
heterozygotes = 2pq
The homozygous recessive percentage = 
q = 0.1
Solve for q:
∴ q = 
∴ q = 
∴ q = 0.316
solve for p:
for p + q = 1,
thus p = 1 – q = 1 – 0.316 = 0.684
The heterozygotes = 2pq
2pq = 2 x 0.316 x 0.684 = 0.432
600 x 0.432 = 259.2 = 259
so, the population reaches Hardy Weinberg equilibrium, 259 of indviduals should be heterozygous for this trait.
Hence, the correct answer is 259
