<h2>Solution:</h2><h3>Given data:</h3>
d= 20g/cm3
m= 10g
formula: d= m/v
By rearranging the formula according to our need:
v= m/d
by putting the values in the formula
v= 10g/20g/cm3
v= 0.5L
So, a rock that has a density of 20g/cm3 and a mass of 10 g would have the volume of 0.5L.
The sun feeds the plants through the process of photosynthesis. the animals gain energy and grow by eating those plants. other animals eat those animals and gain energy and grow. the cycle is never ending and all begins with the sun. without it, the plants and animals wouldnt get food and die off.
Answer:
Genetic diversity in a small population, with a high level of genetic drift and with very little migration will decrease because existing alleles will be lost and few new alleles will be introduced over time (option A).
Explanation:
Evolution - linked to the natural selection and perpetuation of a species - depends, in large part, on three fundamental factors to make it happen:
- Mutations
.
- Genetic drifts.
- Migrations.
In small and isolated populations, very little genetic variation, high levels of genetic drift and very few mutations can be observed, which could lead to some alleles being lost and the species may become extinct.
Genetic drift (GD) is an important factor in terms of natural selection, as it is the result of allelic variations that occur from one generation to another. In large populations, GD is low, given the cross between different individuals is greater. A characteristic of GD in small populations is that their levels are very high, and this leads to the eventual loss of alleles.
In this small population, without the possibility of migration -few new alelles will be introduced- genetic variation will decrease, due the genetic flow is low, reducing reproductive fitness and weakening the population's resistance to environmental changes, which could result in the long-term extinction of the species.

The best description of the graph is that "the percentage of of acres that is dedicated to genetically engineered crops grew from 1996 to 2005"
The y-axis of the graph has the percentage of acres dedicated to genetically modified crops, while the x-axis has the years. The four lines show the four types of crops that are grown. All of the lines are observed to have a direct correlation between the values of y and x, so the percentage of acres dedicated is increasing with time.
Answer would be <span>damage to the nerve cells in the spinal cord.
The spinal cord is responsible for sending nerve signals throughout your whole body. Damage to the spinal cord can result in an inability to send signals to parts of the body, including simple reflexes.
