During meiosis, the ploidy (number of sets of chromosomes) get reduced from diploid (2n) to haploid (n) once telophase I of meiosis I is complete.

<h3>What is meiosis?</h3>

Meiosis is the type of cell division that results in the formation of four daughter cells that are genetically different from one another.

Meiosis is the process that results in the formation of gametes or sex cells in organisms that reproduce sexually.

The process of meiosis is made up of four stages that occurs in two successive divisions;

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

Meiosis reduces the ploidy level of a cell by halving the number of chromosomes of the parent cell. This occurs after the completion of telophase 1 of meiosis I where homologous chromosomes have already separated.

Which is a correct statement about mutation?
leva [86]

Answer: B: Mutation increase variety in a population.

Explanation:Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

Answer:

because

Explanation:

It is an Incomplete question and the complete question is

All healthy, highly productive ecosystems provide which of these essential ecosystem services that involve gases in the atmosphere?

A. increasing carbon dioxide levels in the atmosphere by the action of plants and animals.

B. removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.

C. removing water vapor from the atmosphere and using it to support plant growth.

D. removing methane from atmosphere and storing it's carbon and hydrogen in the tissues of organisms.

Answer:

The answer is removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.

Explanation:

The water and carbon dioxide are byproducts and in which the photosynthesis removes CO2 from the atmosphere and replaces it with O2. In case of respiration it takes O2 from the atmosphere and places it with CO2.

To remove the CO2 it is directly put out of the air and burried it under ground saline aquifers this process is known as carbon capture and sequestration.

Sequestration is a process in which CO2 is removed from atmosphere and stored in the soil carbon pool. This process is mainly done through photosynthesis.
