i know im late but a better answer would be

Some of the sun's energy, though, is reflected from our atmosphere and sent back into space. -Can contain some heat and reflect out some of the heat. What happens to nearly all of the UV radiation that enters the atmosphere The Ozone layer absorbs most of the UV radiation that enters the atmosphere.

Cite the three main types of RNA and describe briefly the function of each.

sveticcg [70]

Answer:

mRNA: Carry genetic information from DNA to protein; serve as template for protein synthesis.

tRNA: Serves as adapter molecule and deliver specific amino acid from the cell pool to the mRNA-ribosome complex.

rRNA: Structural component of ribosomes.

Explanation:

There are three types of nongenetic RNAs: mRNA, tRNA, and rRNA.

1. The messenger RNA (mRNA) is formed by the process of transcription in the nucleus. Transcription uses template strand of DNA to specify the nucleotide sequence in mRNA. The mRNA enters cytoplasm to join ribosomes. The nucleotide sequence of mRNA serves as a template and specifies the amino acid sequence of proteins.

2. The transfer RNA (tRNA) serves as an adapter molecule during the process of protein synthesis and binds to the specific amino acids to deliver them to the protein-synthesizing machinery. The anticodon of tRNA binds to the complementary mRNA codons.

3. The ribosomal RNA (rRNA) serves as structural components for ribosomes. Each of the subunits of ribosomes is made up of rRNA and proteins.

Assoli18 [71]

Answer:

4. Thyroid hormone levels decrease, TRH level increase, PRL level increase

Explanation:

Surgical removal of Thyroid gland will lead to hypothyroidism.

Normally, the surgery is followed by maintenance dose of thyroxine to avoid side effects.

In the presence of hypothyroidism, however, the decreased thyroid hormone will lead to increase in thyrotropin releasing hormone (TRH). increased TRH increases production of prolactin. (but less than that in prolactinoma)

What is the ONLY organ located in the region (umbilical)?

Vitek1552 [10]

Answer:

small intestine

Explanation:

Umbilical. The umbilical region contains the umbilicus (navel), and many parts of the small intestine, such as part of the duodenum, the jejunum, and the illeum. It also contains the transverse colon (the section between the ascending and descending colons) and the bottom portions of both the left and right kidney.
