The graphs below show the changes in crab color at one beach from 1950 to 1990.
The change in crab color is an example of which type of evolution?
O A. Stabilizing selection, because one crab color was preferred over other colors.
O B. Stabilizing selection, because two crab colors were preferred over other colors.
O C. Directional selection, because two extreme colors were preferred over the more moderate color.
O D. Disruptive selection, because two extreme colors were preferred over the more moderate color.
O E. Adaptive radiation, because crabs of a single color evolved to form crabs of several colors.
The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.
What is Natural selection?Natural selection may be defined as the selection of a few individuals from any given population according to their favorable variations.
In 1950, the crab color is in the form of stabilizing selection, while in 1990, it changes to disruptive selection that favors the two extreme colors over the intermediate one.
Disruptive selection occurs when environmental conditions changes in two different directions. Due to which variance increases in population.
Therefore, the correct option is D.

How is childbirth an example of a
positive feedback mechanism?
A. The fetus of a human grows and as it grows
larger the uterus of the mother grows larger.
B. The release of oxytocin leads to increased
contractions which produces more oxytocin.
C. The fluid in the placenta begins to be filtered
out so the baby falls lower.
D. A chemical is released at fertilization that
stimulates the growth of the fetus that releases
more.
The release of oxytocin leads to increased contractions which produce more oxytocin. thus option B is correct.
What do you mean by the positive feedback mechanism?
A system for positive feedback In reaction to an output variation, homeostasis is a mechanism that leads the output to fluctuate even more in the direction of the initial deviation. A positive feedback system amplifies errors and affects the state of the output.
Oxytocin has the effect of imitating more contractions, and so more Oxytocin is released as a result! It's a never-ending cycle of rising contractions and hormone levels to help push the baby.

HELPPP ASAP!! A population of skunks lives in a woodland habitat. The skunks are unable to leave the habitat because of a large mountain. Describe two reasons this population is not at Hardy-Weinberg Equilibrium.
Some of the conditions are there that must be met for a population or an allele to be in Hardy-Weinberg equilibrium equation are:
1. The population of species must be very large.
2. There must be no migration and population must be isolated in a species.
3. There must be no mutations in a population of species.
4. There must be random mating, which means there are no mating preferences.
So, a population will not be according to Hardy-Weinberg Equilibrium if it is small, or there are , which is not raised, but mutations are expected to occur in future. Skunks can also migrate to another region of a woods despite the presence of a large mountain. As a result of possible mutations and migrations, the population is not in Hardy-Weinberg equilibrium.

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.
The sciatic nerve extends from the lower spinal cord to the foot. If a person's sciatic nerve is 0.914 m in length and the speed of an action potential is 107 m/s, how long will it take for a nerve impulse to travel the full distance of this nerve?
Answer:
0.0085420560747664 Seconds
Explanation:
0.914 ÷ 107 = 0.0085420560747664
The time that the nerve will take for a nerve impulse to travel the full distance of this nerve is 0.00854 seconds.
What is a sciatic nerve?Sciatica is caused by a pinched sciatic nerve. The most common cause is a herniated disc in the spine or an overgrowth of bone, known as bone spurs, on the spinal bones.
A tumor can occasionally impose pressure on a nerve. A condition, such as diabetes, can also harm the nerve. The speed of something is how fast the object is moving. It is calculated by the distance divivded by time.
Given, the length of the sciatic nerve is 0.914 m
The speed of an action potential is 107 m/s.
The length is divided by the speed
0.914 / 107 = 0.00854 sec.
Therefore, the full distance of this nerve is 0.00854 seconds.
