Euglena. It does photosynthesis like a plant, and moves around and eats like an animal.
The answer is hard tissue.
Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
The answer is A smaller fragments will move faster.
Answer:
(B) Energy released from the chemical reaction is used to directly phosphorylate ADP.
(D) Energy released from the chemical reaction is used to directly reduce NAD+
Explanation:
phosphorylation is a addition of phosphoryl group to an organic compound.Substrate level phosphorylation is a process where there is ATP is produced from ADP by transferring a high energy phosphate group from phosphorylated metabolic compound.This process occurs in glycolysis and citric acid cycle.and this pathway is exergonic pathway
