Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species.

Answers

Changes to the environmental conditions can indeed result in new ecosystems and a change in the species equilibrium.

Ecosystem disruption

The abiotic conditions of an ecosystem determine the kind of species that will inhabit the ecosystem

A change to the abiotic or environmental conditions will likely result in a new ecosystem entirely. Organisms that are able to adapt to the changes will gradually fade off the ecosystem while those that are able to withstand the changes will proliferate and dominate the populations of organisms in the ecosystem.

HELPPP ASAP!! A population of skunks lives in a woodland habitat. The skunks are unable to leave the habitat because of a large mountain. Describe two reasons this population is not at Hardy-Weinberg Equilibrium.

Answers

Some of the conditions are there that must be met for a population or an allele to be in Hardy-Weinberg equilibrium equation are:

1. The population of species must be very large.

2. There must be no migration and population must be isolated in a species.

3. There must be no mutations in a population of species.

4. There must be random mating, which means there are no mating preferences.

So, a population will not be according to Hardy-Weinberg Equilibrium if it is small, or there are , which is not raised, but mutations are expected to occur in future. Skunks can also migrate to another region of a woods despite the presence of a large mountain. As a result of possible mutations and migrations, the population is not in Hardy-Weinberg equilibrium.

2. why is returning by-catch to the sea not always useful as it might appear?

Answers

Returning by-catch to the sea is not always useful as the sudden change in pressure will result in damage to internal organs of fishes.

What is by-catch?

By-catch refers to other sea animals which are caught along with the intended catch in a fishing expedition.

In some instances some people tend to return by-catch to the sea.

However, this is not always useful as the pressure above sea level or on the sea surface is less than that in the depths of the sea.

A sudden change in pressure will result in damage to internal organs of fishes.

Therefore, returning by-catch to the sea not always useful as it might appear.

a. A warmer climate

Answers

One of the possible effects of increased carbon dioxide concentration on our planet would be a warmer climate.

Greenhouse effect

Carbon dioxide is one of the numerous greenhouse gases that exist in nature. The gases are responsible for the warming of the planet.

Carbon dioxide and other greenhouse gases form a blanket layer in the atmosphere and trap some of the reflected solar radiations from the sun, preventing them from escaping back to space.

The more the concentration of greenhouse gases in the atmosphere, the more the solar radiation that is trapped and the warmer the earth gets.

During the industrial revolution the population of peppered moths went from white to black in color this was because

Answers

Answer:

During the industrial revolution the population of peppered moths went from white to black in color this was because the trees the peppered moths lived on became darker. Thus, it became easier for predators to find white moths than it was to find black moths.

Explanation:

Due to the smog produced from the factories, nearby trees bark turned black. The darker colored moths could then blend in better than the lighter colored moths. The darker moths had higher rates of survival and passed the dark genes to their offspring. Through natural selection, the whole population of peppered moths became black.
