Here's the fact:
"Altering the DNA of plants always reduces the nutritional content" is a FALSE statement. In fact, GMO products often have nutrients added.
"<span>Genetic modification reduces the genetic variation in both plants and animals" is a TRUE statement. The natural genetic variation that keeps species thriving is decreased when the plants are modified. Less diversity within a species puts it at an increased risk of being affected by disease or even becoming extinct. Genetic diversity causes resilience, since not every strain of a species will die off in the case of contracting a disease because they are all different. The more similar species are, the more they are at risk. However, so long as companies make variations of GMO foods, we should be fine.
"There have not been enough long-term studies to prove that this food is safe" is a TRUE statement. Some modern studies say genetically modified foods bad, some say they're good, some say they're neutral; however, since GMOs have only been a thing since 1994, there are no long term studies. Without long term studies, there is no way to confirm the safety of GMO foods.
"There have been many studies showing that these foods cause disease" is a FALSE statement. There have been many studies of GMO foods, but many haven't found any worthwhile data, except a few allergies.
Answer: There have not been enough long-term studies to prove that this food is safe.

DNA Mutation is caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Thus, the correct answer is option D.
1.DNA Mutations are caused by environmental factors known as mutagens.
2.Types of DNA mutagens include radiation, chemicals, and infectious agents.
3.DNA Mutations may be spontaneous in nature.
Sunlight provides energy needed for photosynthesis
its been a while since I've done punnett squares, but I'm pretty sure these are right:
- 2 because two have a dominant curly gene
- 2 because two are double recessive
- 0 because none have double dominant
- 2 because two have a double recessive
BTW I didnt check if you're punnett squares were right so the above is assuming they are
As energy moves through trophic levels in an ecosystem the amount that is available decreases. ... A: Energy flows in a food web by being transferred to and between organisms as they undergo photosynthesis, are consumed by another organism, or decompose.
