Hypothalamus

When there is abnormally high internal temperature, sensors in the Central Nervous System send signals to the hypothalamus. The hypothalamus initiates thermoregulation by sending messages to various organs and body systems with a various mechanisms. High temperature will set off sweating and vasodilation to cool down the body.

Which genetic variation is shown below?

Leno4ka [110]

Answer:

This Punnett square shows incomplete dominance.

Explanation:

The homozygous red flower has two dominant red alleles, and these are represented by the letters RR. The homozygous white flower is represented by rr. Their offspring are all heterozygous Rr, and they have pink flowers. This is the first filial generation, or F1. When the F1 generation cross-pollinates, their offspring will be RR, Rr, and rr in a 1:2:1 ratio. Some of their offspring (the F2 generation) will inherit two R alleles, some will inherit two r alleles, and some will inherit both.

All materials within ecosystems can be recycled.

netineya [11]

Answer:

All the things expect enegry are recycled.

Explanation:

When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled.
The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.

But incase of enegry it cannot be recycled but frequently transfered from one form to another form.

hope it helps..

Anna [14]

Question is incomplete. Complete Question is as follows.

Antibodies are proteins that have a lock-and-key recognition for their antigen established by the antigen-binding site on the antibody. Match the antibodies in the left column to the appropriate blanks in the sentences on the right.

neither anti-A nor anti-B

anti-O

anti-AB

anti-A

anti-A and anti-B

anti-B

1) People who have the A antigen on the surface of their red blood cells have __________antibodies in their plasma.

2) People who have the B antigen on the surface of their red blood cells have ___________ antibodies in their plasma.

3) People who have both A and B antigens on the surface of their red blood cells have ____________ antibodies in their plasma.

4) People who have neither A nor B antigens on the surface of their red blood cells have _________ antibodies in their plasma.

Answer:

1) People who have the A antigen on the surface of their red blood cells have anti-B antibodies in their plasma.

2) People who have the B antigen on the surface of their red blood cells have anti-A antibodies in their plasma.

3) People who have both A and B antigens on the surface of their red blood cells have neither anti-A nor anti B antibodies in their plasma.

4) People who have neither A nor B antigens on the surface of their red blood cells have both anti-A and anti-B antibodies in their plasma.

Explanation:

The antigen present on the surface of the RBC determines the blood group of the person.

The type of antigen present on the RBC determines that which antibody will be present in the blood. Always opposite antibody is present in the blood in order to prevent the reaction of antigen antibody and prevent agglutination.

For example For A antigen , anti A antibody will never be present, always anti-B antibody will be present because if anti-A antibody will be present, it will react with the A antigen resulting in the agglutination of the blood.

similarly all the other blood group antigens are varying with the antibodies.
