Answer:

<u>Reflection-</u> "The term reflection means that when an incident wave interacts with a different medium and changes its angle or direction of travel is known as reflection."

Explanation:

So by taking the first rule of reflection into our consideration we can say that the incident wave coming in interaction with a different medium will reflect with the same angle like that of the incident wave. And will follow the region from where it originates.

<u>Correct option- </u>option "D" is the correct one.

I need help with the image (phenotypes and genotypes).
Flauer [41]

Answer:

See the answer below

Explanation:

1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

     AA   x   aa

  Aa   Aa   Aa   Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>

5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>

What is your stance on genetically modified foods? Are you for or against them?
Vinvika [58]
GMOs have a ton of pros and cons, so it's hard to say. Although, I personally would like to avoid them. With the amount of people who have gone gluten free, there's more of a reason for it than being a hipster or a yuppie. Because the demand for wheat is so high, we had to genetically modify it. Although this increased its abundance, a lot of humans' digestive systems haven't evolved with it. That is the reason why it makes so many people sick, because they cant digest it. If the rate at which GMOs are being created and nourished continues, it's likely our digestive systems will reject it, possibly causing famine due to the inability to eat our own food.<span />
