Ground squirrels are found in many areas of the United States. They live in underground burrows and are often attacked by birds

Ket [755]

The population of the ground squirrels will be limited by the population of the hawks. The population of the hawks, thus, will be a limiting factor for the population of the ground squirrels. The Hawks are the birds of prey that feeds on squirrels. With the increased number of hawks in the same area as them will put these squirrels in danger. The population of the tree squirrels, however, will have no affect on the population of the ground squirrels. The genetic variability and breeding season are not limiting factors for their population either.

Hence, the correct answer is 'option B - a population of hawks'.

Answer:

The most likely pathway is ER - Golgi - vesicles that fuse with plasma membrane.

Explanation:

The endomembrane system is an extensive sets of intracellular membrane. These system was first discovered in the late 1800s when scientist Camillo Golgi noticed that a certain stain selectively marked only some internal cellular membranes. Golgi actually thought that these intracellular membranes were interconnected, but advances in microscopy and biochemical studies of the various membrane-encased organelles later made it clear the organelles in the endomembrane system are separate compartments with specific functions.

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.

Pelvic inflammatory diseases (PID) is an diseases that affect 10-40% of women who had an infection of either gonorrhea or chlamydia and it usually occur when the initial infection such as chlamydia or gonorrhea travels upward with other bacterias beyond the the cervix into the uterus,ovaries, oviducts and pelvic cavity. However, PID is major cause of infertility in young women.
