What type of mutation has occurred in figure 12-3?
Answer= substitution
The correct answer is: ATC GAA CCG TA
Explanation:
All cells have a plasma membrane, ribosomes,and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment. They both use ribosomes for producing proteins.
+sorry i made a mistake on the previous question. Prokaryotic cell doesn't have nucleus. I obviously didn't know the right meaning of this word bc im not a native english speaker
The right answer is D (less responsive to antigens)
It is proven that, after puberty, thymus activity (an organ that is included in the lymphatic system, producing T cells that pick up antigens) decreases and that in adult and aged people the thymus has no role. Work done in humans indicate that in fact the cellularity begins to decline from birth in favor of lymphocyte perivascular spaces and connective and adipose tissue, which leads to a decrease in the capture of antigens.
Answer:
ALL OF THE ABOVE
Explanation:
Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics. Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.
While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.
Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.
Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.
All these causes are related and therefore affects the Florida Panther.
