4 0

Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis <em>ploidy</em><em> </em><em>of</em><em> </em><em>cell</em><em> </em><em>become</em><em> </em><em>half</em><em> </em>

<em>Means</em><em> </em><em>diploid</em><em> </em><em>cell</em><em> </em><em>form</em><em> </em><em>haploid</em><em> </em><em>cells</em>

<em>And</em><em> </em><em>4</em><em> </em><em> </em><em>haploid</em><em> </em><em>daughters</em><em> </em><em>cells</em><em> </em><em>are</em><em> </em><em>formed</em><em>.</em><em> </em>

<em>In</em><em> </em><em>mitosis</em><em>,</em><em> </em><em>ploidy</em><em> </em><em>of</em><em> </em><em>cell</em><em> </em><em>remain</em><em> </em><em>same</em><em> </em>

<em>Means</em><em> </em><em>haploid</em><em> </em><em>form</em><em> </em><em>haploid</em><em> </em><em>and</em><em> </em><em>diploid</em><em> </em><em>form</em><em> </em><em>diploid</em><em>.</em><em> </em>

<em>1</em><em> </em><em>cell</em><em> </em><em>form</em><em> </em><em>2</em><em> </em><em>daughter</em><em> </em><em>cells</em><em>.</em><em> </em>

Nadusha1986 [10]

Answer:

The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:

Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.

These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.
Anton [14]

Answer: blood calcium level

Explanation:

There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity

, systemic blood pressure, and renal artery/arteriole diameters.

Filtration membrane integrity

: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.

Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.

Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.

Blood calcium level do not have any role in the kidney filterate formation or renal regulation.

Hence, the correct option is blood calcium level.
