Heredity is the passage of genetic information from one generation to another. For offspring to inherit traitsthere must be a reliable mechanism for transferring genetic information from one generation to the next.
Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
Answer:
Transport vesicles will not be brought to either the Golgi apparatus or the plasma membrane.
Explanation:
Microtubules forms part of the structure of the cytoskeleton. It is a polymer of tubulins.
Apart from maintaining the cell structure, cytoskeleton plays a role in transportation in a cell.
A Constructive secretory pathway is an exocytosis process found in all eukaryotic cells, in which transport vesicles destined for the plasma membrane leave the trans-Golgi network in a steady stream
A disruption on microtubules will lead to a change in structure of the cytoplasm. It will not be able to perform its function therefore transport vesicles will not be brought to either the plasma membrane or the golgi apparatus.
Blood pressure
This is indicated in Starling's Hypothesis in which there is fluid movement due to filtration across the wall of capillary. This is dependent between hydrostatic pressure gradient and oncotic pressure across the capillary. The balance of these forces allow the net driving pressure for filtration. The net fluid influc is proportional to this net driving pressure. The leakage of proteins across the capillary membrane has important effects and has corresponding cause in the balance of forces.
