Answer:
The correct answer is D) the vacuoles can "come and go" across the plasma membrane.
Explanation:
The endosymbiotic theory exposes that mitochondria and chloroplasts were "swallowed" several years ago by a prokaryotic cell, that then became eukaryotic. These two organelles were originally two living and independent organisms, that's why the have their own DNA and also divide splitting. Anyway, the endosymbiotic theory does not explain anything about vacuoles and also, the sentence is not true. No organelle can come and go across the membrane, it's impossible for an organelle to break such barrier.
Genes are small sections of DNA within the genome that code for proteins
Saturated fatty acids are the type of fatty acids where all of them have single bonds. Their name comes from the fact that usually the second bond they have will be broken up and because of this each half of the bond can be saturated (attached to) with a hydrogen atom that can be available in near vicinity. It is worth noting that thhe fatty acids of fish and plants are mostly unsaturated (either mono-unsaturated or poly-unsaturated) while the fatty acids of animals are mostly saturated.
Answer:
The kind of vegetation in a tropical rain forest is generally determined by the amount of sunlight each layer can accommodate.
Explanation:
Tropical Rainforests are a type of rainforests that happens in regions of tropical rainforest climate where there is no dry season because each month has an average precipitation amounting to 60mm.This forest have divided layers in which vegetation is arranged from a vertical position at each top of the soil to its canopy. The first layer which represents the forest floor can accommodate 2% of sunlight while the second layer, known as the understory layer can accommodate 5% of sunlight.
