for all processes of life.
A) Genes; DNA
B) DNA; proteins
C)Genes; proteins
D)DNA: nucleic acids

Answer:

A

Explanation:

genes are passed down from parent to parent, and when a question asks for "RNA and - ' its almost always DNA

Genes which are carried on chromosomes, are the organized instructions for producing both RNA and  DNA that are necessary for all processes of life.

Biopolymers and macromolecules called nucleic acids are necessary for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base, a phosphate group, and a 5-carbon sugar. Deoxyribonucleic acid and ribonucleic acid are the two primary classes of nucleic acids.

Nucleic acids perform a wide range of tasks, including cell development, the processing and storage of genetic information, the synthesis of proteins, and the production of energy cells.

Therefore, option (A) is correct.

How do the cells and organs of the Skeletal and Muscular system work together?

A newborn child was brought to the hospital nursery before he was marked with his parents' names. The hospital workers must use what they know
about genetic outcomes to determine whom the child belongs to. They use his traits to help them. The baby has freckles (F dominant), and attached
earlobes (I recessive). They believe that the baby most likely belongs to a couple in which the man has attached earlobes but no freckles. It is known that
the woman is heterozygous for freckles and earlobe type.
Complete the Punnett square below to determine the probability that the child belongs to this couple. List the possible combinations of the father's
alleles across the top and the possible combinations of the mother's alleles down the left side. Then write your answer in the space below. Include a
brief statement explaining how you reached your answer.

Sod or turf is grass with the top layer of soil held together by the grass roots. A sod farmer cuts strips of turf and rolls them up for delivery. The fresh sod is used in sports stadiums, golf courses, and lawns.
Back where the turf was removed is an empty expanse of bare dirt. Within a day, seeds from dandelions are dropped by the wind. There is plenty of sunlight and space for the new seeds. No other plants are around to compete. The new plants grow quickly in their habitat and produce many seeds.

Describe how natural selection affects the dandelions just after they arrive and as time passes.
