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.

Yes,
The cell, or plasma membrane, serves as a selectively permeable boundary between the internal cytoplasm and the external environment. All cells are composed of a plasma membrane.
The cell wall is situated to the outside of the cell membrane, and mainly functions to prevent osmotic rupture. Many taxa employ a cell wall, although some function without one
Answer:
The correct answer is d. provide structural support and nutrition to the neuron.
Explanation:
Glial cells are the cells that surround the neurons and provide structural support to them. They also help in insulation for neurons. They are the most abundant cells present in the nervous system.
Many glial cell plays a role in providing nutrition and oxygen to the neurons and regulation of extracellular brain fluid. Glial cells also helps in cleaning up the dead neurons.
The different types of glial cells are ependymal cells, schwann cells, microglia, oligodendrocytes, astrocytes, and satellite cells. So the right answer is d.
