<span>The first part of the question is: The male's ability to shake its tail is the mechanistic cause of this behaviour. For the second part of the question, the mate choice is the adaptive function of this behaviour.</span>
Answer:
0.50
Explanation:
According to the given information, the frequency of the hornless genotype in the population is = 16% = 0.16. This means that the frequency of the hornless allele in the population is = square root of 0.16 = 0.4.
The gene for the horns in unicorn has three alleles. If the frequency of the allele for twisted horns is represented by "p" and that of the hornless allele is represented as "q", then the frequency of the allele for the longhorn would be (r) = 1- (p+q).
This is due to the fact that the sum total of frequencies of all the possible alleles of a particular gene in a population in the Hardy Weinberg Equilibrium is always 1 (p+q+r =1). Now, putting the values of p and q in the formula to calculate the frequency of allele for the longhorn (r) = 1- (0.1 + 0.4) = 1-0.5 = 0.5
Answer:
B) specific heat
Explanation:
The specific heat of a substance is how much heat per unit mass it need to elevate its temperature by one degree Celsius. Its units are joule per kelvin and kilogram, J/(K kg). <em>In the example given you can observe that water need more heat in order to evaporate compared to the alcohol.</em>

Answer:
The given statement is False.
Norepinephrine, also called stress hormone is released by adrenal medulla.
It acts as hormone as well as neurotransmitter in the brain and body.
In brain, it increases alertness, focus, vigilance, and promotes formation as well as retrieval of memory. In addition, it also increases restlessness and anxiety.
In body, it increases heart rate, blood pressure, blood flow towards skeletal muscles, promotes the release of glucose from energy stores, and reduces the blood flow towards gastrointestinal system.
Answer: C
The substance that must come through the cell membrane for the cell to live is nutrients. Cells would die if they did not get nutrients. Nutrients are what keeps the cell running.
