Answer:
Natural selection is an adaptative mechanism that modifies gene frequencies (allele frequencies) in the whole population across generations
Explanation:
According to the evolutionary theory proposed by Darwin, natural selection is the main process that leads to evolution. Natural selection can be defined as a mechanism through which populations adapt and change. The organisms better adapted to their environment will have more chances to survive and reproduce, and therefore they will pass their genes (and favorable traits) to the next generation. This process is able to modify the allele frequencies in the whole population, thereby changing and adapting (i.e., evolving) across generations.
DNA coils tightly during division and assembles into visible?
Answer-Chromosomes
Nummular is a term to describe a lesion size. Nummular size is about a coin size, or 3cm x 5cm. Other sizes could be miliar which was about a dot, lenticular which was around a lentil, and plaque which sizes around a palm of the hand. This size description is not really descriptive since it has various ranges. Actual size in centimeter unit might be better to describe a lesion.
Answer:
The osteoblasts, which should have been building the new bone
Explanation:
Bones are the one of the types of connective tissues and have hard extracellular matrix. Osteoblasts are the cells that serve in formation of extracellular matrix of bones as these cells secrete collagen fibers and inorganic salts present in the matrix of bone. Hence, if a bone is not able to heal after fracture, osteoblast cells should be checked for their activity.
The correct answer is C. Coyotes
Coyotes are organisms in the food web which are both primary and secondary consumers.
