Why is meiosis important for organisms?
It creates gametes and allows for genetic variation among organisms.
It produces genetically identical cells.
0 It provides a means of asexual reproduction.
O It allows for cell and tissue repair

Answers

The correct answer is A. It creates gametes and allows for genetic variation among organisms.

Meiosis is the process of cell division in which a single cell divides into four daughter cells. The genetic constitution of the daughter cells reduces to the half as compared with the parent cells. While crossing over, an exchanging of genetic material is passed between chromosomes and that allow variations to happen.

What are the characteristics of supernovae?

Answers

As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.

You have isolated a highly lethal toxin from an octopus that you have reason to believe binds with high affinity to the pore opening of a voltage-gated sodium channel. To determine the effect of toxin binding, you perform a _______ experiment.

Answers

Answer:

To determine the effect of toxin binding, you perform a Competitive Binding Experiment

Explanation:

Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.

They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.

They are important because:

1. Validate a direct binding assay

2. Confirm whether or not a drug binds to the receptor

3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects
