Answer:

a. The size of their population

Explanation:

If the number of wolves increases but their food supply does not, there will be greater competition for the food.

b. is wrong. The amount of oxygen would have no effect on the competitiveness of the wolves.

c. is wrong. If the amount of food available increases, the wolves will have less need to compete for their food.

d. is wrong. If the area into which the wolves are expanding is like their current habitat, it will contain more food for them. They will have less need to compete.

3. Los conductos linfáticos, a medida que se alejan de los tejidos corporales:

inn [45]

Answer:

b- Se hacen más anchos.

Explanation:

Los conductos o vasos linfáticos son tubos que transporta tanto al líquido linfático (linfa) como glóbulos blancos que fluyen a través del sistema linfático. Estos conductos se inician en el intersticio y terminan en conductos de mayor tamaño que desembocan en la base del cuello, entre las venas yugular interna y la subclavia. A medida que va entrando en los tejidos, los conductos linfáticos se van haciendo cada vez más angostos y finos, convirtiéndose finalmente en capilares linfáticos, donde las sustancias que no pueden penetrar los vasos sanguíneos son recogidas por estos capilares.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri

Reika [66]

Answer:

Explanation:

This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).

In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:

RRYY- RY, RY, RY, RY

RrYy- RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:

RRYY (4)

RRYy (4)

RrYY (4)

RrYy (4)

According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.

This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%
