1. Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
astraxan [27]

1.   The oxygen requirements of an animal cannot be met by the process of     diffusion as diffusion is a very slow process. To overcome this, multicellular organisms have specialized cells and tissues for performing various necessary functions of the body such as intake of oxygen and food.

2.   What criteria do we use to decide whether something is alive? Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.

3.   An organism uses outside raw materials mostly in the form of food and oxygen. The raw materials required by an organism can be quite varied depending on the complexity of the organism and its environment.

4.   The various processes essential for maintaining life are nutrition, respiration, transportation, excretion, control and coordination.

Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swap
Hitman42 [59]

Answer:

The correct answer is ''Translocation​.''  

Explanation:

Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.
