The blood collection centers eventually refuse to take her blood because the frequency with which she gave blood had left her anemic.
Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin.
Therefore her heart must pump more blood to compensate for the lack of oxygen in the blood. The consequences are huge, leading to an enlarged heart or heart failure.

Heart muscle cells would tend to separate without ________

Hitman42 [59]

The answer is intercalated discs. They allow the heart muscle cells to function as one organ due to a phenomenon known as syncytium. This is where uninuclear cells fuse to form an apparent multinucleate cell. This way the heart muscle cells can contract in synch. Intercalated discs appear in the sarcomere's (of the muscle fibres) Z line.

Anuta_ua [19.1K]

The question is incomplete. Here is the complete question.

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov.

The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots.

A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.

Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age.

overo:

white overo:

fewspot:

Answer: Overo: 2

White overo: 0

Fewspot: 3

Explanation: Pintaloosa is a "combination" of overo and leopard, so the pair's genotype is OvovLplp.

To cross a pair, use Punnet Square and to facilitate, use the square for each characteristics:

Punnett Square For overo and white overo:

Ov ov

Ov OvOv Ovov

ov Ovov ovov

Analysing this Punnett square, notice that there are 2 individuals who will carry the genotype for overo (Ovov) phenotype. So, 2 out of the 16 pair will have an overo phenotype.

Since white overo is recessive (ovov) and doesn't survive past birth, there will be zero horses with that phenotype.

Punnett Square For leopard and fewspot:

Lp lp

Lp LpLp Lplp

lp Lplp lplp

From this square, notice that there are 1 individual who is fewspot. However, a horse that is overo and fewspot is considered fewspot, so for the 16 pair, 3 out 16 will be fewspot.

Which of the Caulerpa taxifolia’s traits make it so dangerous to local ecosystem

k0ka [10]

Answer:

Caurepa taxifolia is an invasive species of algae and is listed in the IUCN list of 100 invasive species. 

Explanation:

In is an algae usually found in the pacific ocean. It was earlier used in aquariums as an ornamental species of algae. The dangerously invasive nature overshadows its attractive appearance.

It is inedible and increases in numbers at a surprisingly accelerated rate. The growth of other plants is difficult in areas dominated by the Caurepa taxifolia. The introduction of this algae was in the Meditteranian sea.
