Answer:
Organisms have different proportions of bases in the DNA.
Explanation:
Option B is correct because different organisms have different proportions of bases in their DNA. This makes each species unique. This means that it is not possible for multiple species of have similar proportion of DNA bases.
Other options are incorrect because of following reasons:
1. All the genetic information cannot be universal among all organisms. Different species performs different functions and the genetic information differs accordingly.
2. All animals cannot have similar amount of bases in their DNA. Different animals have different bases.
3. The given table doesn't say that plants are least related. In fact, all organisms differs in terms of DNA bases proportion.
Plants take carbon dioxide (CO2) out of the atmosphere to do photosynthesis, and thus help reduce the greenhouse gases warming the planet.
Explanation:
Plants, through photosynthesis, and soils sequester roughly a third of carbon dioxide emissions released into the atmosphere each decade from the burning of fossil fuels. During photosynthesis, plants open tiny pores on their leaf surfaces to suck carbon dioxide from the air and produce their own food.
Answer:
Natural selection is an important contribution to the theory of evolution because it increases an individual's ability to survive and compete and reproduce.
Explanation:
Ok, I'm not 100% sure this is correct, given the context of the situation, but basically, the cell membrane helps the cell maintain homeostasis by keeping what needs to be in in & what needs to be out out. If it weren't for the cell membrane having the structure it does, all kinds of things could get into the cell & completely kill it from filling it with too much stuff, or the wrong things could get in (say, things with a really odd pH) & damage it badly. Or, it could let things get out extremely easily, such as enzymes and ions the cell needs to function properly.
Hope this helps!
