Answer:Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.

<h2>A) option is correct </h2>
Explanation:
Skin has two types of sweat glands: eccrine and apocrine
Eccrine glands occur over most of the body and open directly onto the surface of skin whereas apocrine glands open into the hair follicle, leading to the surface of the skin and develop in areas abundant in hair follicles, such as on scalp, armpits and groin
The eccrine gland is controlled by the sympathetic nervous system and regulates body temperature
In some animals, when internal temperature rises the eccrine glands secrete water to the skin surface, where heat is removed by evaporation
Eccrine glands when active are considered major thermoregulatory devices
Smaller mammals, such as rodents, cannot endure dehydration and hence possess no eccrine glands at all

here is the answer of this qquestion
Answer:
In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!
To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."
I hope this helps a little bit.
