Answer:
Water, carbon dioxide,oxygen and some other substances can pass through the cell membrane because oxygen and carbon dioxide moves across the cell membranes from a simple diffusion a process that does not require any energy input and is driven by differences in concentration on the other side of the cell membrane.
In shorthorn cattle, color shows incomplete dominance. A red cow has the genotype RR. A white cow
has the genotype ww. Heterozygous cattle are called Roan (red and white spotted) (RW).
1. Cross a red bull with a roan cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow
Answer:
red cow would be 50% and the same for a roan cow
Cross a Red Bull with a roan cow. The Punnett Square are
% Red Cow = 25% red
% Roan Cow = 50% roan
% White Cow = 25% white
What is a Punnett square?A Punnett square is a square with a block that is used to see and describe the offspring of the next generation. It contains both genotypes, dominant and recessive, and then there is a crossing over.
Given that, the red cow has genotype RR
A white cow has the genotype ww.
Heterozygous cattle are called Roan (red and white spotted) (RW).
When RR (red) is crossed with WW (white), it results in a roan color.
RR (red) x WW (white) = RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.

How do T-cells help with destroying viruses?
Answer:T-cells are a type of white blood cell that work with macrophages. Unlike macrophages that can attack any invading cell or virus, each T-cell can fight only one type of virus. You might think this means macrophages are stronger than T-cells, but they aren’t. Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body.The T-cell receptor fits with its antigen like a complex key. When the perfectly shaped virus antigen on an infected cell fits into the Killer T-cell receptor, the T-cell releases perforin and cytotoxins. ... Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside.
