Based on the risk factors discussed in the film, which of the following groups should consider taking vitamin D supplements to avoid rickets? A. Adults with dark skin who live close to the equator. B. Children born to parents with light skin living close to the equator. C. Adults with light skin who live far from the equator. D. Children born to parents with dark skin living far from the equator.

D) Children born to parents with dark skin living far away from the equator

Explanation:

Rickets is a disease condition in children which is characterized by the softening and weakening of the bones caused by the deficiency of vitamin D.

Vitamin D is responsible the absorption of calcium and calcium plays a role in the formation of stronger bones and teeth.

Children born to parents with dark skin living far away from the equator are at a risk of developing rickets. As vitamin D is majorly naturally produced in our skin on exposure to sunlight, a dark skin prevents adequate penetration of sunlight into the skin.

Also, living far away from the equator where there is little sunlight all year, complicates the issue.

In order to resolve this, such kids should be given vitamin D supplements to meet their daily needs.

not sure but try c two haploid cells

explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
