Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.
Answer:
cess for GE crops conducted by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), and the U.S. Food and Drug Administration (FDA). Other evidence came from studies published by regulatory agencies in other countries or by companies, nongovernmental organizations (NGOs), and academic institutions. The committee also sought evidence from the public and from the speakers at its public meetings and webinars.1
The committee thinks that it is important to make clear that there are limits to what can be known about the health effects of any food, whether non-GE or GE. If the question asked is “Is it likely that eating this food today will make me sick tomorrow?” researchers have methods of getting quantitative answers. However, if the question is “Is it likely that eating

A mammals need for oxygen effects their heart rate because there could be some cases where they're in lack of oxygen causing them to be literally ' out of breath ' . Like climbing a mountain. The higher you go the less oxygen.
Hope I helped !!11!!!!! :)
<span> Sexual reproduction is more likely to increase genetic diversity because every offspring has twice as much genetic material to pull from when being formed compared to the one set of genes in asexual reproduction. There is also the differences between mates that can increase genetic diversity as well if many different mates are mated with.
Asexual reproduction typically happens more quickly, however, because an asexually reproducing organism does not have to bother with finding a mate, courting and allowing time for the genetic material assimilate, they can just reproduce and all of their genes are utilized in the new organism rather than just half.
The whiptail lizard may reproduce either sexually or asexually depending on the environmental conditions.</span>
