Carbon dioxide emissions are contributing to climate change, which is causing average global temperatures to increase. These tem

perature increases have led to a loss of sea ice in the Arctic. Populations of polar bears, which depend on sea ice as part of their habitat, have declined as a result of this loss. The rate of Arctic sea ice loss is predicted to increase if the current temperature trends continue.
What is the best long-term solution to help maintain polar bear populations?

A. introducing plants capable of bioremediation to the Arctic

B. replacing fossil fuels with renewable energy sources

C. identifying new sources of fossil fuels around the world

D. establishing several protected regions in the Arctic

The best solution is - B. replacing fossil fuels with renewable energy sources.

By replacing the fossil fuels with renewable energy sources the enormous release of carbon dioxide into the atmosphere will be stopped and minimized because the renewable energy sources are not emitting Greenhouse gasses into the atmosphere.

Unfortunately, this type of energy sources still can not satisfy the demand, and also big problem represents the economic justification of their usage, and lots of countries are not willing to lose profit in order to protect the environment.

Answer:

C) Platelets

Explanation:

Hemophilia is caused by a lack of clotting factors. Because platelets (or lack thereof) are what is responsible for how the blood clots, it can be reasonably inferred that the answer is C.

(Platelets secrete procoagualants, which are clotting factors. If there is a genetic issue with how these clotting factors work, then the platelets will not be useful.)

Yuliya22 [10]

Answer:

The parents must be Tt, Tt

Explanation:

Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:

     T      t

T    TT   Tt

t     Tt     tt

We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).

This means that the parents must be Tt, Tt.
