Answer: 15
Explanation: I think but is a gamete has 23 chromosome it has 23 parents chromosome so it should be the same equal
Answer:
c. Proteins
Explanation:
A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.
Pre-modern-high birth rate and death rate
Mature industrial-low birth rates, death rates are constant
Industrialization-high birth rate and low death rate
Answer:
The ultimate level of causation refers to the behavior’s evolutionary significance; how the behavior enhances reproductive fitness. The proximate cause refers to the immediate cause of a behavior, whether that be hormonal, neurological, cognitive, interpersonal, or cultural. For example, the proximate cause of humans eating more cookies, cake, and ice cream involves the psychological tendency to desire and enjoy foods with high sugar and fat content. The ultimate cause involves the high caloric content of both sweet and high fat foods, which promotes physical survival in resource-scarce environments.
Answer:
The correct answer is C. The enzyme that ensures there is an equal distribution of newly synthesized phospholipids across the membrane is the scramblase.
Explanation:
Scramblases are proteins used to move phospholipids from one monolayer to another of the lipid bilayer inside the plasma membrane of a cell. This protein, unlike flippase, is not selective with respect to lipids but "reverses" them on the other side of the membrane in a random and non-specific manner. It therefore causes the phospholipids not to be added only on one side when the membrane is formed or expanded, but also on the opposite side in contact with the extracellular environment.
