Answer Choices:

DNA provides the energy needed for an organism to grow and function

DNA is copied into mRNA, which controls cellular functions

DNA codes for proteins, which allow an organism to grow and function

DNA unzips and each strand codes for a different amino acid

Answer:

DNA codes for proteins, which allow an organism to grow and function

Explanation:

DNA provides the energy needed for an organism to grow and function - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.

DNA is copied into mRNA, which controls cellular functions - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.

DNA codes for proteins, which allow an organism to grow and function - this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell

DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid

Under what conditions might a person with rh- blood develop rh agglutinins

Mamont248 [21]

A person who has rh- blood can develop rh agglutins through;

1. Pregnancy.
2. Transfusion.
3. Exposure to blood.

Agglutination is termed as clumping of particles. It is the process which occurs when an antigen is mixed with its corresponding antibody known as isoagglutinin.
When people are being given blood transfusion of wrong blood group then the antibodies will react incorrectly with the transfused blood group, then the erythrocytes clump up and stick together which causes them to agglutinate.

The ability of body systems to increase their function, given the need to adapt, is known as the The ability of body systems to

Whitepunk [10]

Answer:

The ability of body systems to increase their function, given the need to adapt, is known as the physiologic reserve.

Explanation:

The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
