omeli [17]3 years ago
5 0

Answer:

Proximal convoluted tubule

Explanation:

The major work of re-absorption is carried out in nephron by the proximal convoluted tubule (PCT). The PCT re-absorbs all the essential nutrients such as amino acid, potassium, glucose etc. and water driven by passive transfer based on concentration gradient. Along with gradient, pH of the urine also affects the re-absorption. Based on the pH of the urine (basic or acid), re-absorption of ionized acid increases or decreases.

When does the exponential growth of a population stop?
Advocard [28]

Answer:

When the population reaches its carrying capacity.

Explanation:

As a population grows, there is more competition for resources which can limit a population. There are also natural disasters that can play a role too such as disease. Another factor that is part of carrying capacity is the size of the habitat. If there is no room, then the population cannot increase.
