Answer:

The loss of Arctic ice leads to increase in sea level. This occurs as the melted ice run into oceans, and as the ice expand due to sunlight intensity.The aftermath of this is increase in flooding. Which may disrupt Cultivation of crops and and animals husbandry leading to shortage of foods - famine.

Besides, it leads to sea less will become less stable, vegetation cover will be destroyed, animals specific to particular habitats are disappearing. This ultimately affect human population survival.

Answer:

As the ice melts in the arctic regions, the arctic sea levels and the other oceans stay the same. The weather however changes when this happens and results to the Greenland's melting ice sheet adding another 20 feet to sea level rise.

In summary, the melting of polar ice caps effects would result in sea levels rising around 220 feet or more worldwide.

This will lead to destruction of lives, houses and properties due to water submersion.

How does having one sickle cell gene usually affect a person?

kumpel [21]

Answer:

A person who receives a gene for sickle cell disease from one parent and a normal gene from the other has a condition called "sickle cell trait." Sickle cell trait produces no symptoms or problems for most people. Sickle cell disease can neither be contracted nor passed on to another person.

What are two modes of genetic variation of organisms

Arada [10]

The genetic variation of organisms has three sources they are mutation, gene flow and sexual reproduction.

Explanation:

Genetic variation are caused by mutation , random mating, random fertilization and recombination between homologous chromosomes during meiosis.

It is a variation in alleles and genes, among the populations. There is a genetic variation within the family of closely- related individuals. If it is a neighborhood there are many families and there is also genetic variation among that group.

An exact genetic copy of the parent organism is produced in asexual reproduction. It only introduces the genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

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.
