Answer:

The genotype of the Dad must be X^AY because that's the only possible genotype for a normal male.

The genotype of the mom must be X^AX^a because that's the only way to have a colorblind son while being a normal mom. The colorblind son gets a Y from his dad and X^a from his mom.

The genotype ratio among the children must be 25% heterozygous dominant, 50% homozygous dominant, and 25% heterozygous recessive.

The phenotype ratio among the children must be 75% normal and 25% colorblind.

<h2>The Red-Cockaded Woodpeckers</h2>

Explanation:

Red-cockaded woodpeckers are sharp, socially adroit, and adorable.
They assemble settles by unearthing pits in old pine trees in the Southeast, which was an incredible transformative system until individuals cleaved down 97 percent of their natural surroundings.
<em> Snakes are a portion of their most risky home predators</em>, so the <em>winged animals peck the pine trees' bark </em>to make sap overflow down the tree trunk. The smooth of sap stops winds and protects the nest cavities above.
Each pine tree in a backwoods into timber or turpentine, it sets aside a long effort for trees to become large enough to help respectable size home depressions.
The <em>tree timberlands these flying creatures</em> advanced in was intermittently gotten out by fire, which is currently typically stifled, prompting woods that are unreasonably thick ridiculous.

What happens when the s phase cannot enter the g0 phase?

Shtirlitz [24]

<span>The importance of the G0 phase is that during cell division when the cell get a signal that there are enough of cells (not more required) or there is a mutation in the cell that need to be fixed before they differentiate fully or the cell during its division gets damage then it is signalled to rest, and it is this phase that cell leave the cycle and quit dividing. It could be temporary resting period (so when cell again required, or damaged got fixed) then the cells will again join the cycle and continue to divide again or it can also be permanent for example neurons, which are resting in G0 phase and never divides again.</span>

In what stage does the skin blister allowing bacteria to enter the site of the pressure ulcer

dimaraw [331]

I think it is stage 2
At stage two, the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful. The sore expands into deeper layers of the skin. It may appear as a scrape, blister, or a shallow crater in the skin. At times this stage looks like a blister filled with clear liquid. Also at this stage some skin may be damaged beyond repair or may die.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?

koban [17]

I believe the correct response would be C. Plants acquire carbohydrates by producing them through the process of photosynthesis. This allows plants to then use the formed carbohydrates to build structural polymers, such as cellulose.
