Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.

Which of the following is evidence for continental drift?
A. There is one continent on Earth. .
B. Places with hot climates once had glaciers. C. There are no mountains in Africa.
D. North America has no volcancus.
Explanation:
its b i think if its right your welcome if its not let me know
The evidence for continent drift theory is that places with hot climates once had glaciers. Therefore, option B is correct.
What is continental drift theory?According to the Theory of Continental Drift, the continents of the Earth move relative to one another and appear to be drifting over the ocean floor together.
Wegener constructed a ring around the south pole using the regions that had been ice-covered. The conclusion of the theory is, Over the past 300 million years, the continents have drifted to their present locations after having formerly been a single, bigger continent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift. Hence, option B is correct.

When is the possibility of solar weather affecting terrestrial weather the highest?
A. during solar minimum
B. during the solar cycle
C. during solar maximum
D. during Total Solar Irradiance
Solar maximum is the peak when the sun's activity and its effect on terrestrial weather will be maximum. Thus, option C is correct.
What is solar maximum?Solar maximum is referred as the highest activity exhibited by the sun during its solar cycle of eleven years.
Solar maximum is an outcome of sun's magnetic poles that produces greater solar eruptions. The large number of sun spots are found as a result.
These sun spots are rich in energy and thus contributes to greater activity of the sun.
Higher the activity of the sun, higher will be its effect on terrestrial weather as sun is the main source of energy for terrestrial life.
Opposite to solar maximum is solar minimum when the activity of the sun is lowered due to reduced sun spots.
Sun storms are the example of solar maximum.
Thus, solar maximum and solar minimum are the important part of solar cycle.

a predator population suddenly decreases even though the prey population stays the same. Besides disease, what could explain this change?
Answer:
hunting, the predator is in the middle of the food chain
Explanation:
hunting can WIPE OUT species as shown by the dodo bird in the past.
food chains often work as 1-2-3 or 1-2-3-4 in levels.
A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.
What happens if in a particular food web a new prey animals are introduced?If in a particular food web a new prey animals are introduced, that will most likely result in the increase of the populations of the predators in that food web. The reason why the populations of the predators would increase is that there will be more pray to hunt, and more food means that the predators can increase in numbers and not suffer from food shortage.
Still, while this the most likely scenario, it has to be taken with a little bit of reserve, as it also depends on what kind of prey animal would be introduced in the food web, and what kind of predators are there in the food web. The predators in that food web are small to medium sized predators like the serval, honey badger, than there will be no increase in the predator populations as they will not be able to hunt the introduced pray animal.
Therefore, A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

skin cancer caused by UV exposurenot passed on to offspringfound only in a specific cell typewhat are Somatic Mutation and Inherited Mutation?Mutations that a person inherits from their parents are called hereditary mutations. they're found in all body cells and may be passed down to new generations. acquired mutations occur during an individual's life.
A somatic mutation is a change within the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; this is, any mutation that takes place in a cell other than a gamete, germ cell, or gametocyte.
