Why do you think that dilating blood vessels will decrease temperature of the blood as well as decrease blood pressure?

Answers

Answer 1
Dilation of blood vessels will cause them to be nearer to the skin surface. This means that it will be easier for heat to be lost from the blood vessels to the skin and ultimately to the atmosphere via conduction. This loss in heat reduces the temperature of blood and hence the body temperature in general.
If the rate at which blood is pumped is constant (whether blood vessels are constricted or dilated), then blood pressure decreases when blood vessels are dilated because blood pumped at constant speed has more space to pass resulting in decreased blood pressure.

where does pollination takes place in the flower

Answers

Answer:

An epistatic allele in labrador retrievers ensures that ee lab pups are yellow. Two other alleles control coat color, where black is dominant to brown. What portion of yellow pups would you expect from a parental cross where one parent was yellow (Bbee) and the other was heterozygous

Answers

Answer:

1/4

Explanation:

Epistasis is defined as a phenomenon in a genetics where the effect of the gene mutation which dependent on the absence or the presence of the mutation in more than one genes.

In the context, an epistatic allele in the Labrador retrievers which ensures the ee lab pups that are yellow and the two other alleles which control coat color are black that is dominant to the brown.

Thus, 1/4 portion of the yellow pups would expect from the parental cross where one of the parent is yellow (Bbee) and the other is heterozygous.

Thus the answer is 1/4.

Do you think if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions?

Answers

Answer:

yea

Explanation:

cause our climate conditions changes everyday depends on the atmosphere at that time so if there fire in a forest all the animals there have to adapt to the smoke.

Yes, if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions.

Why plants and animals will change their features?

Plants and animals are fundamentally different in many ways, but one of the most obvious is in how they deal with temperature.The climatic niche of a species reflects where it can live.A species with a wide climatic niche can range widely across many different conditions and may be especially resilient to climate change.Different sets of plant and animal species tend to occur at different elevations, which differ in temperature and precipitation.

As a baby grows into an adult, the type of cellular reproduction used is mitosis.

Answers

Answer:

Mitosis.

Explanation:

Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell.
