The answer is the third one. Rice would provide everyone with food but would not allow for all the needed nutrients to be absorbed. Rice is a starch or carb and that's the only compound you would be getting. Your body would then lack other nutrients like protein, and calcium that allow your body to grow and develop properly.
Sexual reproduction produces far more genetic variation than asexual reproduction. I’m asexual reproduction, only one organism is needed. In this process they copy their own DNA and create an exact copy of themselves. So, if you think about it, all the offspring ever created by that one organism is going to have the same genetics as it. They’re all going to be identical. There is no variation, or differences, between any of the offspring and the original organism. Bacteria reproduces this way, although through binary fission, they can sort of reproduce sexually.
Sexual reproduction results in genetic variation. Two organisms are needed to create offspring. An egg cell and a sperm cell are needed from a female and male organism to create the new organism. Since two organisms are required, their offspring will be a mix of their DNA. This will create variation between offspring. Every new organism will have different genetics.
This is why more advanced organisms like plants and animals have different DNA even if they are the same species.
The answer is D, the rate of soil erosion has increased
After the 1st half-life 250 g of the radioactive material will be left.
<span>After the 2nd half-life 125 g of the radioactive material will be left. </span>
<span>After the 3rd half-life 62.5 g of the radioactive material will be left. </span>
<span>Therefore after 60 minutes, 3 half lives would have occurred. </span>
<span>Therefore the half-life = 60 / 3 = 20 minutes when 250 grams of the original material would have remained radioactive. </span>
<span>Therefore the answer is A) About 250 gram of the material decayed in 20 minutes.</span>
Answer:
8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes
Explanation:
The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.
