Answer: Catecholamine
Explanation:
Catecholamine are monoamine nuerotransmitters secreted by the adrenal gland when you are under physical or emotional stress. When adrenal gland secretes these hormones they result in an increased cardiac output, breathing, blood pressure and increased blood flow to the skeletal muscles to accommodate the fight or flight response activated during stressful conditions.

Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
A monohybrid cross only involves one trait, for example "shape". A dihybrid cross involves two traits, for example "shape " and "height".
Answer:
1. Terrestrial Animals:
Animals which live on land are called terrestrial animals. They generally have four legs. Terrestrial animals have well-developed sense organs. E.g. Tiger, Lion, Elephant, Dogs, Cat etc.
2. Aquatic Animals:
Animals which live in water are called aquatic animals. Many aquatic animals like fishes have special respiratory organs called gills. Gills consists of membranes and are connected with blood vessels. Gills extract dissolved oxygen from water and excrete carbon dioxide.
3. Aerial Animals:
Animals which spend most of their time in the air are called aerial animals. Birds come under this category.
4. Arboreal Animals:
Arboreal animals live on trees. E.g. monkeys, lizards, squirrel, chameleon etc.
5. Amphibians:
Amphibians can live in water as well as land. Amphibians are cold-blooded. Amphibians don't have scaly skin. Their skin is slimy and permeable that means air and water can pass through it.Some amphibians have gills at the beginning of their life. Some examples of amphibians are frogs, toads, salamanders and caecilians.
