Answer:
A purine always forms a complementary base pair with a pyrimidine.
Explanation:
Purine bases such as Adenine pair specifically with Thymine , a pyrimidine base forming two bonds; just as Guanine pair specifically with Cytosine forming three bonds.
This specific base pairing are complimentary in nature and grants stability to the DNA.
the source of the filtrate is Loop of Henle.
The Henle loop is surrounded by tissue fluid with a high ion concentration. Osmosis causes water to move out of the descending limb. As a result of the more concentrated filtrate, ions move out of the loop in the thin ascending limb.
The nephron consists of a single long tubule and a ball of capillaries called the glomerulus. Using hydrostatic pressure, plasma is forced through the walls of the glomerulus, becoming filtrate as it crosses, and then collecting within Bowman's capsule. The fluid that enters vertebrate nephrons is called the filtrate.
<h3>Which part of the nephron is called the loop of Henle?</h3>
A million nephrons are the filtering units of the human kidney, which is a complex and highly vascular organ. Each filters water and solutes from the blood that flows through it into the surrounding space and is the cavity between the cup's walls. The other part resembles a U-shaped loop that transports the filtered fluid deep into the medulla.
<h3>Functions of Nephron</h3>
The primary function of the Nephron is to flush out waste products from the blood, which include solid waste and other excesses. This blood is transformed into urine through secretion and excretion.
The nephron, a basic structural unit of the kidney, is a microscopic structure composed of a renal corpuscle and a renal tubule.

I would say Cone cells are responsible for this
water, habitat, competition, predation, climate
When there is heavy competition between two species these results may surface. First, even if there is just a little advantage of one species, the tendency is the best competitors will dominate the other. This may lead to the extinction of the weaker species. Another result is, competition may cause the traits of the competing species to evolve. This result is called character displacement. This is what happens when for instance the species live in the same area and have the same and common niche; the characteristics of the species evolve in order for them to minimize niche overlap. This is also for them not to have competitive exclusion. To add to that, when there is heavy competition, the finite resources will not be enough for all competitors who have all access to the resources. This may lead to very low survival rates.
