I believe it is the ascending loop of henle. In the ascending portion, the loop becomes impermeable to water and instead the cells of the loop, actively reabsorb the solute; thus water is not reabsorbed but ions are readily reabsorbed. As the ions are reabsorbed the concentration becomes more and more hypotonic until it reaches 100-150 mOsm/L. Therefore, the ascending loop is called the diluting segment of the nephron due to its ability to dilute the fluid in the loop from 1200 to 100 mOsm/L.
Answer:
The proximal tubule of nephron in the kidney is composed of single layer of cuboidal cells that are covered with striated borders.
Explanation:
Proximal tubules or proximal convoluted tubule is an important part of vertebrate kidney which is located between bowman's capsule and loop of Henle.
Proximal tubules are divided into 2 parts- Proximal convoluted tubules and Proximal straight tubules.
Proximal convoluted tubules are located entirely to the renal cortex and the Proximal straight tubules descend into the outer medulla.
The major function of Proximal tubules are mainly absorption and secretion.
The proximal tubules helps to regulate the pH from the filtration and also causes sodium reabsorption that is driven by P type ATPase.70% re absorption of sodium takes place in the proximal tubules through active transport.
Moreover elimination of ammonia takes place through proximal tubules by breaking glutamine to alpha ketoglutarate.
Answer: Increased reproductive success of individuals with the ability to survive in a variety of water temperatures
Explanation: Natural selection establishes that the conditions of an environment favor or hinder (select) the reproduction of organisms according to their characteristics. Natural selection was proposed by Darwin as a means to explain biological evolution.
The trait subject to selection must be inheritable.
There must be variability of the trait among the individuals of a population.
The variability of the trait must give rise to differences in the survival or success of the player, making certain characteristics of the new appearance can be extended in the population.
The accumulation of these changes over generations would produce all evolutionary phenomena.
Commensalism
Explanation:
In the rainforest, small plants called bromeliads lives on the branches of tall trees which allows them to receive sunlight for photosynthesis. They are commensals in this regard.
The interaction between the plant and the bromeliads is a commensalism.
Commensalism is a feeding relationship in which one organism derives benefit from the other without causing it harm.
- It is a positive - zero relationship in which one organism benefit and the other is not harmed.
- In mutualism, both organism derives benefits from one another.
- For parasitism, one organism derives benefit and causes harm to the other.
