Answer:

C. Photosynthesis OR D

Explanation:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. It fits the image pretty well.

***C makes the most sense to me, but it could be D. I'm not sure.

Forgive me if I'm wrong.

What is converting the genetic code into the language of proteins?

Ulleksa [173]

This is a process called transcription and translation.

Information to synthesize a particular protein is found in DNA in the cell nucleus. This information is copied (transcribed) onto messenger RNA or mRNA in short. The copying process is called transcription.

mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. Transfer RNA or tRNA then begins to read (translate) the information on the attached mRNA. This is the process of translation.

tRNA then fetches amino acids that correspond to this information and brings them to the ribosome where they are linked together into a chain. This chain of amino acids is the primary structure of the protein.

Timothy has attached earlobes like his maternal grandfather. His mother and father both have free earlobes, which are dominant.

gavmur [86]

its H because his maternal grandfather is on his moms side of the family and has the recessive allele not his grandfather on his dad's side

The dominant allele H reduces the number of body bristles in fruit flies, giving rise to a hairless phenotype. In the homozygous

DerKrebs [107]

Answer:

a. 3:1 (normal bristles to hairless)

b. 2:1 (normal bristles to hairless)

Explanation:

a. If H allele is present, the fly will be hairless. But H allele is lethal at homozygous condition, so all hairless flies will be heterozygous for H locus (Hh). S allele has no effect on bristle number, but in presence of H allele, S produces a "normal" phenotype and is also lethal at the homozygous condition. So genotypes and phenotypes will be like this:

- SSHH: No viable- Lethal

- SSHh: No viable-Lethal

- SShh: No viable-Lehtal

- SsHH: No viable-Lethal

- SsHh: Normal

- Sshh: Hairless

- ssHH: Normal

- ssHh: Normal

- sshh: Normal

A cross between two normal flies carrying the two alleles (SsHh) will produce (according to the attached Punnett Square):

6 Normal (SsHh, ssHh, and sshh)

2 Hairless (Sshh)

Therefore, the ratio of flies with normal bristles to hairless individuals will be 3:1.

b. When the hairless progeny of the previous cross (Sshh) are crossed with one of the parental normal flies from part a (SsHh), it will be produced (according to the second Punnett Square):

8 Normal (SsHh, ssHh, and sshh)

4 Hairless (Sshh)

So, the ratio of flies with normal bristles to hairless individuals will be 2:1.

Terminal buttons.

Explanation:

Neurons are longest animal cell that serve as the basic unit of their nervous system.

The neuron is divided into two parts-

Cyton: It is the cell body of the neuron. It has projection extending from the cytoplasm that receive signals called dendrites.

Axon: It is a long process extending from the cyton that carries the impulse from cell body to end of neuron. The axon terminate at knob like structures called terminal button . These release neurotransmitter and are rich in mitochondria.
