Answer:

a. The spindle apparatus is present in cells undergoing <u>mitosis and meiosis. </u><u> </u>the spindle is crucial for chromosome sorting.

b. Chromosome replication occurs just prior to <u>mitosis and meiosis I. </u> DNA needs to be copied during S fase to have enough DNA and transfer it to the daughter cells.

c. The cells resulting from <u>mitosis </u>in a haploid cell have a ploidy of n.

Mitosis produces identical cells.

d. The cells resulting from <u>meiosis II </u>in a diploid cell have a ploidy of n. meiosis is the only process that causes chromosome reduction (assuming no errors).

(e). Homologous chromosome pairing regularly occurs during <u>meiosis I.</u>  Each daughter cell needs 1 chromosome of each kind

(f). Non-homologous chromosome pairing regularly occurs during <u>none</u>. This is kind of an error.

(g). Physical recombination leading to the production of recombinant progeny classes occurs during <u>Meiosis I </u>

(h). Centromere división occurs during meiosis II and mitosis

(i) Non-sister chromatids are found in the same cell during <u>meiosis II</u>

PLEASE ANSWER QUICKLY Which statement about cell theory is INCORRECT? New cells are spontaneously created from existing cells. A
Mazyrski [523]

Answer:

New cells are spontaneously created from existing cells

Explanation:

In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:

1) Cells are the fundamental and basic unit of all life and structure.

2) All living organisms are made up of one or more of these cells.

3) New cells arise from already pre-existing cells.

These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.

Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.

State one adaptation of nephron in the kidney of a desert mammal​
lidiya [134]

Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.

Explanation:

The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
