1. In what ways does an organism’s mode of reproduction impact the diversity of its offspring? (Asexual vs. Sexual)
Katen [24]

Answer:

<u>Asexual reproduction</u> = An exact copy of the reproducer

<u>Sexual reproduction</u> = Genetic variation into the organism if a random mutation in the organism's DNA is transmitted to offspring.

Explanation:

Example of Asexual Reproduction diversity - A red apple has apple seeds. You plant the red apple seeds, and it grows up to be no different than the apple before it.

Sexual reproduction Example of diversity -Two parents are of different ethnicities. The female gets pregnant, but because of the different genetics from both of the parents, the child will inherit their genetics + some random mutation in the DNA.  

This impacts the diversity of the offspring because it can be an exact copy of the reproducer (Asexual), or significantly different with some similarities if the mode of reproduction was sexual.

I really hope this helps you! Please tell me if it did or not. Good luck with your assignment/exam/quiz!

(OMG TYSM FOR BRAINLIEST!! :D)

Most of the earth's volcanoes:
Murrr4er [49]

<em>They mostly occur at boundaries between tectonic plates. They can also be found by a belt called the "Ring of Fire" that encircles the Pacific Ocean. Volcanoes like that can be formed in Hawaii Islands in the part of the interior plate. These areas are known for being called the "hot spots." </em>

The first order reaction A → B, has k = 2.10. If the initial concentration of reactant A is 1.500 M, how long will it take [A] =
Semenov [28]

Answer:

ln( \binom{at}{ao}{}  )  =  - kt

Explanation:

ln( \binom{0.6}{1.5} )  =  - 2.1t

ln(0.4)  =  - 2.1t

T = 0.436.

I used the formula for first order reaction.

I hope you get this.
