Answer:
The fossil record shows that early species of horses were generally small in size, but many lineages since about 30 million years ago exhibit substantial change toward an increase in size.
Explanation:
It was demonstrated that variation in size as well as in diet during the last millions of years, were consequences of different climatic and geographic changes.
The fragmentation of horses´ populations was associated with habitat heterogeneity and to a new tendency for colonizing new areas that were not accessible before that time.
When great plains with grasslands appeared, horses moved to these new areas, reproduced, and got bigger and taller with time. The new species became even bigger. They evolved from small mammals that fed on shrubs in the forests, to the big current horses that graze on the open plains.
Answer: If this pump quits working (as happens under anoxic conditions when ATP is lost), or if the action of the pump is hindered (as happens with heart glycosides, for example, digoxin), Na+ aggregates inside the cell and intracellular K+ falls.
Explanation:
The way toward moving sodium and potassium particles over the cell layer is a functioning vehicle procedure including the hydrolysis of ATP to give the necessary energy. It achieves the vehicle of three Na+ to the outside of the cell and the vehicle of two K+ particles ions to the inside. In this manner, if the sodium-potassium siphon quits working both Na+ aggregates inside the cell and intracellular K+ falls.
Answer:
Explanation:
When u have exposure to stress, stress can be a major risk factor for various diseases. i found a study that states how stress is involved where it implies that the brain and gut are linked in a way that the brain can affect the gut as if you are having lets say butterfly's in your stomach, Mood alteration or mood change is also a sign of stress aswell. I also found in a paragraph that one way that can lead to better digestion is regular stress management like: Exercising regularly, going outside, setting up a profitabble sleep schedule, less time with electronics, or trying meditation or other forms of relaxation at bedtim or throughout the day.Reducing stress can lower inflammation in the gut, ease GI distress, and keep you nourished, since your body can focus on absorbing the nutrients you need.
