<span> It's solar, because s</span>olar energy is a renewable resource that is virtually endless as long as the sun shines.<span />

Renewable resources are the resources of energy which can be rapidly replaced with the natural resources, such processes, such as energy derived from the wind or sun. The renewable fuels are a better way of deriving energy than from the non-renewable fuels such as the fossil fuels (LPG, and natural gas). The biofuels can be derived from the vegetable oils etc).

Hence, the answer is 'biofuels'.

Identify the type of mutation that occurred and explain in what way it affected the protien

Ira Lisetskai [31]

Answer:

The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.

Explanation:

The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.

In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.

Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. E

ikadub [295]

Answer:

Because the offspring of a male and female are always going to be xx, xx, xy, or xy.

Explanation:

Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.

So we can write the this out in a punnet square as(link down below).

After you see the visual, you will find that the genotypes are xx, xx, xy, xy.

As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.

So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
