Answer:

Hi There! :P

Explanation:

A controlled experiment is simply an experiment in which all factors are held constant except for one: the independent variable. A common type of controlled experiment compares a control group against an experimental group. All variables are identical between the two groups except for the factor being tested.

Cattle and buffalo share a similar fundamental niche, the entire set of conditions under which a population can survive and repr
Vadim26 [7]

Answer:

The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.

Explanation:

2.

From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.

3.

When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.

From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.

4.

Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.

Meiosis I: in meiosis I there is pair of chromosomes called homologous chromosomes which are to be seperated so one of that two chromosomes right pole of the cell and the second one goes to the left pole so each pole gets a chromosome with two sister chromatids.

Meiosis II: While in meiosis II homologous pair is not formed and single array of chromosomes are arranged to form metaphase plate as formed in Mitosis so, when the spindle fibres contracts each sister chromatids went to their respective poles.

The majority of water reabsorption from the filtrate occurs in the _____ ____ ______.
const2013 [10]

The majority of water reabsorption from the filtrate occurs in the proximal convoluted tubule (PCT).

Further Explanation:

The nephron is the functional unit of the kidney which plays key role in the removal of waste product from the body. Nephron consists of glomerulus and convoluted tubules.

Parts of the nephron:

1. <u>Proximal convoluted tubule (PCT):</u> It is the first part of nephron which is closer to the glomerulus. It consists of microvilli and various carrier protein which increases its surface area for reabsorption. This part is responsible for the reabsorption of sodium chloride, glucose, water, amino acid, bicarbonate etc.

2. <u>Henle loop</u>: This is present after PCT. As it forms loop like structure therefore it is named so. It consist of ascending loop and descending loop. This part is responsible for the reabsorption of water, sodium and chloride.

3. <u>Distal convoluted tubule</u>: It is the last part of the nephron which empties its filtrate into the collecting duct. This part is responsible for the reabsorption sodium and chloride.
