Answer:
Explanation:
There are many options, here are a few choices:
Fast moving water tends to be colder than slow water; some of it originates as snow melt on the sides of mountains, for example. For this, animals in fast water tend to be more cold resistant. This is why you do not see fish like freshwater trout in equatorial regions. These animals struggle and die in slow, warm water.
Fast moving water means that if the animal or plant wants to stay put, it must resist the flow. Fish tend to be far more muscular and lean in these places, while insects like stoneflies, mayflies, and other larvae have ways to secure themselves to rocks and plants while growing. Plants develop strong root systems, and algae hold fast in rocky crevices in the river. Some animals also have suction in order to stay in place where there is fast flowing water.
Some animals have to adapt their reproductive systems as well. Because finding a mate is difficult in the sweeping waters, breeding tends to happen all at one time. As an example, salmon have runs, where thousands of fish all swim upriver at once to breed, can dramatically alter the surrounding ecology of the river. Insects like mayflies have hatches, where hundreds of thousands of flies swarm into the air at once to breed and lay eggs.
Answer:
25%
Explanation:
T = Hitchhiker's thumb
t = straight thumb
B = Brown eyes
b = blue eyes
The man's genotype is ttBb
The woman's genotype is Ttbb
Make a dihybrid punnett square to find the possible genotypes of the offspring
ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:
Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype
4 ÷ 16 = 0.25
0.25 × 100 = 25%
The appropriate response is the concept of conservation. Conservation alludes to an intelligent deduction capacity which, as indicated by the clinician Jean Piaget, is absent in youngsters amid the preoperational phase of their improvement at ages 2– 7, yet creates in the solid operational stage at ages 7– 11.
Answer:
A tan might indicate sun damage to the skin.
Explanation:
Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.
A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.
Based on the facts presented about the moon, the statement that supports the idea that what we always see is the same side of the moon is statement 1. The moon rotates on its axis for about four weeks or one month.and this happens about the same period that it orbits the Earth.
