Why are protists considered the precursors to the eukaryotic diversity of life on the planet today
liubo4ka [24]

The protists belong to the kingdom Protista that comes under the domain Eukarya. Protists are a very broad group, comprising of various eukaryotes that do not fit into the other kingdoms, like animals, plants, and fungi. The protists were the initial eukaryotes.  

They would go on to become the precursors for each of the other eukaryotic kingdoms. By examining protists one can witness the transformation between the single-cell prokaryotes and modern multicellular eukaryotes.

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   <u>anti-B </u>  antibodies in their plasma.

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

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

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

Name and describe the role of each of the chambers in the rats heart. name the major artery and major vein connected to the hear
Nat2105 [25]
Easy:

The four chambers of the heart are the right and left atria, and the right and left ventricles. The main veins connected the heart are the superior and inferior vena cava, the main artery is the Aorta.

The first chamber, (the right atruim) recieves deoxygenated blood and forces it into the right ventricles which forces the blood into the lungs for oxygenation. Then the blood reenters the heart in the left atrium, which forces the blood into the left ventricle and then out the Aorta to the rest of the body.

sorry, but this question needed kind of a long answer to be answered correctly.
