How does incomplete dominance differ from a dominant recessive pair of alleles?

1 answer:

6 0

Incomplete dominance is when both of the the alleles represented are heterozygous thus creating a third phenotype known as a blend e.g white and red flowers gives a pink one. Whereas dominant recessive both alleles are homozygous and thus the phenotype depicts that gene.

What are the chromosomes called when they look like Xs

Marina86 [1]

Answer:

I think you're referring to the Metaphase...

Explanation:

During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".

These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.

This "Zipping Up" makes the chromosomes more visible.

As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....

An individual sustained a closed head injury in a rock climbing accident. In the ER the RN elevates the head of the bed at 30 de

mote1985 [20]

Answer:

Answered below

Explanation:

Head injuries may be penetrating head injury or closed head injury.

A major concern for health professionals regarding intracranial injuries resulting from closed head traumas, is the management of intracranial pressure. Elevated intracranial pressure have negative effects on the brain and immediate management of raised intracranial pressure is important to avoid cerebral edema, intracranial hematoma, brain herniation and even death.

The usual procedures in the management of head injury include elevating the head to about 30 degrees. This position promotes cerebral venous drainage and decreases intracranial venous pressure and intracranial pressure as well.

This is helpful because when the patient is left in the horizontal position, the intracranial pressure becomes significantly higher and the have fatal consequences.

A proton gradient is established with the buildup of hydrogen ions on one side of the inner membrane of the mitochondria in euka

GenaCL600 [577]

B. ATP synthase. The purpose of the hydrogen gradient is to take advantage of molecules' tendency to move from areas of higher concentration to areas of lower concentration. ATP synthase lets hydrogen ions flow through it to the matrix, and the energy from this flow is used by ATP synthase to synthesize ATP.
