6 0

Answer:

Anaphase II.

Explanation:

Meiosis may be defined as the process of cell division in which a single diploid cell is divided into the four haploid cells. Two stages of meiosis are meiosis I and meiosis II.

The anaphase II of the meiosis consists leads to the finals stage of meiosis after telophase division. The chromosome at this stage is consists of the single chromatid and is similar as anaphase of the mitosis. The anaphase stage results in the maintenance of the genetic constitution of the cell.

Thus, the correct answer is option (C).

Which statement best explains why correct protein folding is critical in the transmembrane protein shown above?
amid [387]

The statement 'interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane' explains why protein folding is critical. This process is fundamental for the function of transmembrane proteins.

Protein folding refers to the process by which a polypeptide (i.e., a protein) adopts its final tridimensional 3D shape (conformation).

In a protein, some amino acids contain hydrophilic R groups, whereas other amino acids contain hydrophobic R groups.

During protein folding, hydrophobic amino acids are arranged so they can interact with the long chains of the fatty acids in the internal region of the lipid bilayer, whereas hydrophilic amino acids are arranged so they interact with water on the surface of the cell membrane.

Virty [35]

Answer:

Big mammals as bears or Mammoths.

Explanation:

Neanderthal had a diet based in different food, for example, there are some evidence that they were feed on nuts, mushroom, and moss. The quantity of veggies were different depending the season and the region of the planet the neanderthals were.  Of course, most of their diet were based in meat, basically  of big animals because the evidence is that they had a digestive system appropriate to eat lean protein.

Studies of the bones and the coprolites showed a ratio of different elements as nitrogen and carbon, the ratio of the heavier element to the lighter, show the relationship among the meat/vegetable diet.

Hope this info is useful.

scoray [572]
<h2>Baroreceptors </h2>

Explanation:

  • Baroreceptors are splash type nerve endings in the walls of veins and the heart that are invigorated by without a doubt the degree of, and changes in, blood vessel pressure. They are amazingly rich in the mass of the bifurcation of the inner carotid corridors (carotid sinus) and in the mass of the aortic curve. The essential site of end of baroreceptor afferent strands is the NTS.  
  • The capacity of the baroreceptors is to keep up foundational circulatory strain at a moderately steady level, particularly during an adjustment in body position. Flawless baroreceptors are very viable in keeping quick changes in pulse from minute to minute or hour to hour, but since of their versatility to delayed changes of circulatory strain (> 2 or 3 days), the framework is unequipped for long term regulation of blood vessel pressure.
