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  - <u>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</u>

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

<u>Evolution is sometimes a controversial:</u>

Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.

I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.

I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.

Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.

9966 [12]

Answer:

A - Hypothalamus and Antidiuretic Hormones

Explanation:

Whenever their is a sudden change in the fluid level in the bodyb, either the blood, sugar, etc., the osmoreceptors, a special group of cells within the hypothalamus part of the brain, will detect this.

Thereafter, a signal is sent to the posterior pituitary gland to release the antidiuretic hormones (ADH), whose job is to maintain the fluid level by causing an increase in water reabsorption into the body through the expansion of the epithelial cells of the kidney.
