<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.
Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.
A red coat color has this genotype: AA
A white coat color has this genotype: aa
To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>
The answer is A btw you don’t have to use that chart the best way to do or the easy way to do it by doing it on the amino acid wheel it’s much better and faster.
Let me know if you have any questions:)
Fluid filled sacs in the knee are specifically called Bursa or Bursae. Bursae is plural for Bursa.
A bursa is a closed fluid filled sac that function as a gliding surface to reduce friction between tissues of the body. Knee bursitis occurs when there is irritation or inflammation in one one of the knee bursa. The procedure of removing fluid-filled sac is called bursectomy. When the bursa become infected with bacteria, this condition is called septic bursitis.
Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus.
3. ---- D. Water would flow into them because they are hypertonic to external environment.
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
