Answer:
1. All red calves i.e. RR
2. All roan calves i.e RW
3. 2 red calves (RR) and two roan calves (RW)
Explanation:
According to this question, a gene coding for fur colour in cattle is involved. Red alleles (R) and white alleles (W) are co-dominant to produce a roan cattle (RW). The possible traits of the following crosses are (see attached punnet square):
1) A red bull (RR) is mated to a red (RR) cow: All red calves i.e. RR
2) A red (RR) bullis mated with white (WW) cow: All roan calves i.e RW
3) A roan bull (RW) is mated with red (RR) cow: 2 red calves (RR) and two roan calves (RW).
Answer:
yes,its true
Explanation:
I just want to say first off
the immune cell known as T cell also known as white blood cells
Since the first main attack from the bodies response against a virus is deploying T cells to attack
CD4 cells are the basic T cells and HIV virus which is AIDS will start to "Eat itself inside" Ofc not they will use protein spikes to form their way in
they start to create copies of themselves inside the T cell itself and creating a new protein called Env to form their ways in ofc
They are able to bypass CD4 cells is because its a basic cellular receptor for T cells making them really deadly
They now will start to attack other white cells and deploying more and more of their virus cells
Answer:
theory is diffrent from law
Explanation:
a Theory can never be proven to be true nd a law can usually be expressed
Answer:
12.1% C, 16.1% O, 71.8% Cl
Explanation:
i hope this is correct
Answer:
Hydroxyl ion concentration is 
.
Explanation:
From the given,
pH of the solution = 11.30
pH+pOH = 14
11.30 + pOH = 14
pOH = 14-11.30 = 2.7
The pOH of the solution is 2.7
<u>Concentration of hydroxyl ion:</u>
![2.7= -log[OH^{-}]](https://tex.z-dn.net/?f=2.7%3D%20-log%5BOH%5E%7B-%7D%5D)
![log[OH^{-}]= -2.7=5.08\times10^{-11}M](https://tex.z-dn.net/?f=log%5BOH%5E%7B-%7D%5D%3D%20-2.7%3D5.08%5Ctimes10%5E%7B-11%7DM)
Therefore, hydroxylion concentration is .
