All of them. Air because in helps make food it also lets the plant breath. Water because it helps move nutrients into the plant. Soil because plants can’t grow without soil.
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.

Answer:
Explanation:
1)Pfr/Pr
2) Pr
3)far-red
Explanation:
The leaves at the top of a tree’s canopy are exposed to direct sunlight during the day, and their phytochromes will occur in a high *Pfr/Pr* ratio. Meanwhile, the leaves of the same tree at the bottom of the canopy are highly shaded during the day and will likely have a higher proportion of the * ( PHYTOCHROME )Pr *;form of phytochrome present due to exposure to a higher proportion of *FAR RED * light.
Plants make use of the phytochrome system to it's adjust growth based on the seasons. Through phytochrome plants is able to respond to the timing and duration of dark and light periods. At dawn, all the phytochrome molecules present in the leaved are converted to the active Pfr form until sunset this is because the sun is unfiltered, and unfiltered sunlight has high percentage of red light, but lower far-red light, with the help of phytochrome system , the plants is able to compare the length of dark periods over several days.
No, only corn is a legume.
Answer:
C. a whale's flipper and a cat's leg
Explanation:
Homologous structures are the organs which have same basic anatomical structure but they perform different function based on the type of environment in which the organism is living. Two organisms which have homologous organs indicate that both the organisms are evolutionarily closely related to each other i.e. their ancestry is common. It is basically divergent evolution which is responsible for formation of homologous organs. If two closely related organisms are living in different environment then their organs which basically have same origin will tend to perform different functions as a part of adaptation. In contrast to this, analogous structures are the ones which perform similar function but anatomically they are very different and evolutionarily they are not closely related. Analogous structures are evolved as a result of convergent evolution which is meant for adaptation in a particular environment. So, even if two organisms are not closely related they still develop the structures which perform similar function so as to adapt into a particular environment.
Whales and cats both are mammals so they are closely related to each other but since they live in different environment, their organs which are anatomically similar perform different functions. Flippers in whales help in swimming while cat's leg help in walking. So, option C is correct answer.
All other options are examples of analogous organs.
A bird's wings and a butterfly's wings are perfect example of analogous organs. A bird is a vertebrate while a butterfly is an arthropod so evolutionarily they are very distantly related so their wings are also anatomically very dissimilar but they still perform similar function which help these two organisms in flying. So option A is incorrect. Similarly option D is also incorrect because wasp is an arthropod while dolphin is a vertebrate. Option B is also incorrect because catfish is a vertebrate and bee is an arthropod.
