Mmm idk why either. Evolution is not proven as no one kept apes and see it grow into a human. It doesn't really make sense too. Animals don't have moral judgement, and can't create and understand images of art and drawing. It is weird if apes somehow adopts the abilities and become a human.
According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
The answer should be the contraction of muscles.
Hope this helps mate.
Answer:
Steroid hormones
Explanation:
Steroid hormones are the second largest groups of hormones. They are made up of small cholestrol units and are fat soluble, therefore they can pass easily through cell membranes.
Function:
They have roles in many vital functions of our body such as salt and water balance, formation of sexual traits,immunity related functions,metabolism and improving health by withstanding injuries.
Mode of action:
- Steroids being hormones can effect the processes of body in two ways: They affect the transcription of genes involved in synthesis of certain proteins- this is called genomic level action.
- They can affect by binding with specific membrane receptors like G-proteins, Ion channels and transporters- non genomic level function. Through these ways, they can affect many mechanisms occurring inside the cell.
Hope it helps!
