Compare and contrast the structure and function of the anterior and posterior pituitary glands. drag the appropriate items to th

borishaifa [10]

Anterior Pituitary or adenohypophysis has two parts: pars distalis and pars intermedia..though they are kinda joined in humans.
•Pars distalis (actuallyknown as the anterior pituitary) secretes hormones like Growth Hormone or Somatotrophin, Prolactin, TSH, ACTH,LH,FSH.
•Pars intermedia secretes only one hormone MSH (Melanocyte Stimulating Hormone)
•Posterior pituitary or Neurohypophysis stores two hormones (originally secreted by the hypothalamus) which are Oxytocin and Vasopressin or ADH.

Cheers..dont forget to deem this answer as a brainy answer :)

Need a hypothesis for “How are proteins built from RNA”

Dima020 [189]

Hi!

Hypothesis:

<em>Proteins are built from the translation of messenger RNA (mRNA) molecules</em>

RNA, or ribonucleic acid, is a structure that is similar to DNA, except that it exists as a single strand, consists of a ribose sugar instead of a deoxyribose sugar and has the base uracil (U) instead of thyamine (T).

RNA is generated through transcription of the DNA molecule, resulting in a <em>complementary </em>molecule of the template DNA strand. For instance, if the sequence of the DNA was:

ATGCGCAGTTATTGCGAT

The corresponding RNA sequence will be:

UACGCGUCAAUAACGCUA <em>(complementary with U instead of T)</em>

<h3><u>From RNA to Protein</u></h3>

The RNA molecule in our case is known as the mRNA. After transcription the mRNA molecule is transported to the cytoplasm, where a ribosome binds to it for another molecule to translate the sequence. This translation is mediated by an RNA molecule known as the tRNA molecule which enters the ribosome to catalyze the reaction.

These molecules identify a sequence of 3 bases (codon) and for specific codon sequences, the tRNA allocates specific amino acid. For instance, for the codon <em>UCA</em>, the tRNA will allocate a <em>Serine residue.</em>

This translation process starts at specific three base sequences, known as start codons, and terminates at specific three base sequences known as stop codons.

In this manner, a sequence of amino acids respective to the mRNA codon sequence is synthesized, and as we identify proteins as chains of amino acids that are covalently linked together through peptide bonds, we can clearly see that proteins are built directly from RNA, and indirectly from DNA.

Hope this helps!

A population of white-tailed deer inhabits a certain patch of forest in michigan. Which group of alleles can be considered the g

emmainna [20.7K]

Answer:

the dominant alleles of white-tailed deer in this population only!

Explanation:A group of individuals of the same species that interbreed with each other is known as a population. The study of change in genetics is called population genetics which includes genes and alleles.

Complete set of genes and their alleles that are present in a population is called gene pool. Gene pool includes both dominant and recessive alleles of every gene present in a population that can be transmitted in the next generation.

Population with high genetic pool has high diversity which increases the fitness of a population. As gene pool include all the genes and its allele in a population, therefore, the correct answer is all alleles of the white-tailed deer in this population only.

Precipitation _____. drives the water cycle is the change from a solid to a gas happens more frequently than evaporation over la

ipn [44]

Answer: Precipitation occur more frequently than evaporation over land.

Explanation:

Precipitation refers to the water vapour that fall from the atmosphere in form of rain, snow, sleet, freezing rain or hail. It delivers water from the atmosphere to the Earth. Precipitation occur more on the land than evaporation, most water that teaches the surface of the Earth fall back on the land and fill the inland water, rivers , storages,e.t.c.

Evaporation occur frequently in the ocean because it is expose to the sun and most water that is evaporated from the ocean fall back to the ocean as precipitation.
