All genetic information is stored in DNA are divided into units called ____
rusak2 [61]
Okay, biology isn't exactly my strongest subject (it never has been), but I'm pretty sure the answer is nucleotides. DNA is made up of nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. There are four different nitrogen bases: adenine (A), thymine (T), guanine (G), and cytosine (C). A always pairs with T, and G always pairs with C.

<h2>Urea </h2>

Explanation:

Urea is a small nitrogenous compound which is the main end product of protein catabolism in mammals

  • Urea is a nitrogen-containing substance normally cleared from the blood by the kidney into the urine
  • It is made predominantly in the liver from ammonia and bicarbonate and is one of the main components of urine
  • The rate of synthesis varies from 300 to 600 mmol/day depending on the protein intake
  • All of this urea eventually finds its way into the urine
  • Because urea makes up a large part of the obligatory solute excretion, its osmotic pressure requires significant volumes of water to carry the urea
  • Urea passively crosses biological membranes, but its permeability is low because of its low solubility in the lipid bilayer
  • Some cells speed up this process through urea transporters, which move urea by facilitated diffusion
  • Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear
  • Urea transporters have not yet been identified for the proximal tubule

tamaranim1 [39]

Answer:

Your answer is A.They contain chloroplasts both in the mesophyll and bundle sheath cells.

Explanation:

 C4 plants have two types of photosynthetic cells: mesophyll and bundle sheath cells. Mesophyll chloroplasts are randomly distributed along cell walls, whereas bundle sheath chloroplasts are located close to the vascular tissues or mesophyll cells depending on the plant species. The cell-specific C4 chloroplast arrangement is established during cell maturation, and is maintained throughout the life of the cell.
