Answer:
double helix
Explanation:
Deoxyribonucleic acid, commonly known as DNA, consists of two long polynucleotide chains composed of four types of nucleotide subunits i.e. A, G, C, T. Each chain is called a strand. Each nucleotide is made up of a pentose sugar, phosphate group and a nitrogenous base.
DNA is a double-helical structure that contains each strand in a spiral or coiled form. This double helix structure forms when two complementary strands are held together by hydrogen bonds. The bonding occurs between the nucleotide base portions of the complementary strands e.g G-C, A-T.
They are called "products".
The kidney's intrinsic capacity to control blood flow gives the ability to regulate glomerular filtration.
<h2>
What is renal autoregulation?</h2>
Renal autoregulation is a mechanism that allows the kidneys to maintain constant blood flow and glomerular filtration rate (GFR). This is hugely important to keep homeostasis for several reasons:
- The right blood flow and GFR are necessary for excreting metabolic wastes, which avoids poisoning.
- It is key to maintain the electrolyte balance by finely regulating water and ions reabsorption.
- In case of high arterial pressure, autoregulation protects the glomerular capillaries from suffering an injury.
<h3>Mechanisms involved in renal autoregulation</h3>
Two mechanisms take part in Renal autoregulation:
- Myogenic response: preglomerular arterioles (especially at the level of afferent arterioles) can sense elevations in transmural pressure, which induces their contraction.
- Tubuloglomerular feedback: when the tubular fluid reaches the macula densa located in the distant tubule, the cells on it can detect changes in the concentration of sodium chloride, which is dependent on flow rate, and induce a modification in the diameter of the afferent arteriole.
In conclusion, blood flow and glomerular filtration are two hugely important factors in renal function and both can be regulated by the kidney itself via two mechanisms.

The answer is D. The dark mice could not camouflage on the white beach sand hence were more conspicuous. Therefore, the Predators were able to easily spot them and prey on them. Therefore, the phenotype of dark mice reduced in the population since most mice were not able to reach maturity and pass down their traits. The allele for white fur, therefore, increased in the population. This is the process of natural selection at work.
