Answer:
<u><em>There is a 25% chance for solid white coats. </em></u>
Explanation:
To check the chances of a solid white coat offspring being formed, lets make a punnet square.
The gametes of the parents will be W and R v/s W and R.
W R
W WW WR
R WR RR
A punnet square is a diagram which is made to test the outcomes of a cross.
As the following punnet square shows:
- There is 25% chance for solid white coat offspring to be formed (WW).
- There is a 50% chance for the offspring to be roan (WR).
- There is a 25% chance for the offspring to have solid red coats (RR).
Some have been noted to live as long as 6 days without there head.
Answer:
c) microevolution
Explanation:
Microevolution is the change in allelic frequencies within a population over time.
If natural selection favored birds with beaks and small bodies, that means that the frequency of that phenotype (beak and small body) increased while the frequency of birds with body and large beaks decreased.
In this example we see that in the Darwin's finches population, the allelic frequencies - reflected in the phenotype - changed over time as a consequence of the drought.
Diffusion is the movement of the molecule (in gaseous form) from a region of high concentration to a region of low concentration until equilibrium is achieved. The movement of these molecules is always down the gradient and the movement of the molecules is stochastic
Endocytosis is the uptake of large molecule, that can't pass through the pores of the cell membrane, by a cell. It involves the invagination of the cell membrane engulfing the materials and budding off into a vesicle. The materials are therefore internalized and are transported into the cell.
Exocytosis is the reverse of endocytosis. The material comes from inside of the cell and carried in a vesicle. The vesicle binds with the cell membrane and the part in contact with the cell membrane diffuses off. The contents of the vesicle are therefore emptied outside of the cell.
Phagocytosis is the ingestion of an organism such as bacteria by another cell such as a phagocytic immune cell or amoeba. The process of phagocytosis is similar to that of endocytosis. However, this process is aided by cell membrane receptors on the surface of the phagocyte that recognizes and binds the epitopes of the bacteria.
Osmotic pressure is the bare minimum pressure required to be exerted to prevent the movement of water, by osmosis, from a low concentrated solution to a higher concentrated solution through a semipermeable membrane.
If two heterozygous parents mate, the phenotypes of the resulting offspring will be 75% dominant and 25% recessive
