The time that it would take for the population to double is about 7 years.

<h3>What is population?</h3>

The population of an area refers to the number if people that live in that particular area per time. The life expectancy of a population is increased by adequate sanitation. When there is over  population in an area, it can lead to malnutrition and decreased food production.

A density dependent factor that affects population growth is disease transmission. The countries with the highest populations in the world do not necessarily have the fastest population growth. One factor that has led to lower fertility rates in Europe and North America is educational opportunity for women.

The occurrence which is not a potential consequence of Earth reaching its global capacity is less spread of disease.

Using;

P= Poe^rt

P = 74,000

Po = 37,000

r = 0.1

Hence;

74,000 = 37,000e^0.1t

74,000/37,000 = e^0.1t

2 = e^0.1t

ln2 = 0.1t

t = ln2/0.1

t = 7 years

The proximal tubule of the nephron in the kidney is composed of
Dmitry_Shevchenko [17]

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.
