<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
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The birth of modern science (c.1500-1700) was important to how we understand the knowledge and disciplinary divisions today because the scientific method was established to get proper validation to the things in nature that in the past were attributed only to dive concepts expressed by the Church.
That old fashion way of thinking, validated by the church during the dark ages of Medieval Times, only created fear and fostered ignorance in people.
The advent of modern science changed this thing, basing its theories and answers on proper research that could be proven. That is how the human mind expanded and grew. No more myths and distorted religious beliefs that were so wrong.
The answer is A. One way for scientists to gather
information about operons in organisms
is by examining the genome sequence, such as by making use of the intergenic
distance between frames to count the number of operons there is in the genome.
