Answer: false
Explanation: because it mutation can help or not help in many ways think of a mocking bird if its beck was short it would have a less chance of surviving. if the mockingbird had a longer beck it would surviving .This leads up to natural selection.
Answer:
B) 300
Explanation:
There are two types of alleles present for wing type in this population of Drosophila, c and c+. Various combinations of these two alleles will produce different phenotypes.
c+c+ : straight wings = 45
c+c: straight wings = 70
cc: curly wings = 35
Total flies = 150
Each fly has one gene with two alleles for wing type. Hence 150 flies will have 300 alleles in the gene pool.
Your answer should be tissues.
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.
