Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.
Answer:
Pressure
Explanation:
The pressure from the other layers makes it impossible for any liquid to flow, but since it is getting pressed from all around, it is solid.

Perhaps it's Zygomyocota? Or Fungi imperfection? I'm a bio major and we have only ever touched on this once in my years of college. You don't really will need to know this if your pursing a more in depth science major just FYI :) but it's good to be aware
Answer:
For the first one the answer is 1) Sodium/potassium pump. For the second one is 2) Active transport. For the last one is 3) b. passive transport osmosis.
Explanation:
1) Sodium/Potassium pump requires ATP for it to start carrying three sodiums to the extracellular fluid and two potassiums to the intracellular fluid.
2) During active transport molecules like glucose, use a protein channel to enter or leave the cell. Although in most cells, glucose goes through the membrane with pumps, it's not general, and in some cells other mechanisms are used. But glucose is always too big to enter the cell with other than active transport.
3) The diffusion of water through a semipermeable membrane is an example of passive transport and osmosis. Water molecules are small enough to go through the cell membrane without any carrier, it also, goes with the gradient, and therefore osmosis happens.
