What are some examples of reduction division?

Biology
1 answer:
Rufina [12.5K]3 years ago
7 0

Answer:

Reduction division: The first cell division in meiosis, the process by which germ cells are formed. In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). Also known as first meiotic division and first meiosis.

Explanation:

ok!!!

The division of a bacterial cell into two daughter cells (called binary fission) is accomplished by a protein called FtsZ. FtsZ
Katena32 [7]

The question is incomplete and the complete question is:

For each space in the table, drags the appropriate label to indicate if the statement is true or false for each group of organisms

1. Cells divide by constriction of a ring of protein

2. The presence of a cell wall prevents the cell from diving by constriction

3. Tubulin or tubulin-molecules function in binary fission(in bacteria) or cytokinesis(in animals and plants)

Answer:

1. Bacteria: true , Animals: true  and Plants: false

2 bacteria: false , Animals: false and Plants: true

3. Bacteria: true , Animals: false  and Plants: true

Explanation:

Option-1

Bacteria: true  as the protein FtsZ is involved in the binary fission and the formation of constriction.

Animals: true  as the microtubule ring is formed

Plants: false  as no constriction of the ring is formed instead of a cell divides by plate formation

<u>Option-2</u>

<u> </u>Bacteria: false  as the ring is formed and no cell wall is involved

Animals: false as there is no cell wall in the animals

Plants: true as the cell wall divides by plate formation

Option-3

Bacteria: true  as FtsZ is involved in the ring formation which is tubulin like structure

Animals: false  as the actin and myosin are involved in a ring formation

Plants: true as tubulin are involved

Art [367]

Evolutionary game theory is a mathematical modeling approach to predicting the outcome of natural selection on behaviours when multiple organisms are interacting.

<h3>What is natural selection? </h3>

According to modern concept of evolution natural selection is not a bloody battle as was emphasized by Darwin and Wallace.

It is a peaceful process that has little to do with, "struggle for existence" or "elimination of unfit" or "survival of the fittest".

Natural selection really means differential reproduction ( some members of the population produce lage no of offspring, some are few and still others none.

Those that produce large no of offspring contribute greater percentage of genes to the gene pool of the next generation than those that produce fewer offspring.

If differential reproduction continues for many generation ,then genes of the individual which produce more offspring will become predominant in the gene pool of the population.

This leads to change in the gene frequency of the population.

Individual which are best adopted to the environment having greater no of surviving ones.

Survival of the organism to the reproductive age and their selection for mating is the important factors which results in differential reproduction.

There are three types of natural selection stabilizing

selection, directional selection and disruptive selection.

BRAINLIESTTT ASAP!<br><br> Explain passive and active transport across the cell membrane.
Sliva [168]

Active transport is the movement of molecules or ions against a concentration gradient. Passive transport is the movement of molecules or ions from an area of higher to lower concentration.

Passive transport does NOT require energy

-Diffusion - small uncharged molecules

-Osmosis - water

-Facilitated diffusion - glucose

Active transport REQUIRES energy

-Ion pumps

-Endocytosis

-Exocytosis
