Answer:
b) from a region of high pressure to a region of low pressure
Explanation:
Blood flow is measured in blood volume per unit time. It is the movement of blood through an organ, tissue or vessel. It is initiated when ventricles in heart contract leading to its ejection at high pressure. Major arteries receive this blood and they further transport it at high pressure to smaller arteries, arterioles and capillaries. Hence arteries have thick walls to withstand this pressure. The pressure decreases when blood reaches to veins hence their walls are not that thick. Hence, blood flows from a region of high pressure to a region of low pressure.
A very large star of high luminosity and low surface temperature. Red giants are thought to be in a late stage of evolution when no hydrogen remains in the core to fuel nuclear fusion.
Answer:
6/16 dogs will not be able to smell.
Explanation:
Genes A and B are considered for scent smell.
Individuals homozygous for either one or both of the nonfunctional recessive alleles are not able to smell.
The final cross would be AaBb x AaBb which has outcome of;
Individual with homozygous nonfunctional recessive alleles (bold ones):
- One nonfunctional recessive alleles: Aabb, aaBB, aaBb, Aabb, aaBb (5/16)
- Two nonfunctional recessive alleles: aabb (1/16)
- All nonfunctional recessive alleles: 6/16 dogs that could not smell scents
