Answer:
Natural selection is an evolutionary process which occurs over hundreds and thousands of years. These effects are visible when we look closely at a population, because they surpass the lifetime of an individual. Moreover, the process of natural selection is involved with the evolution of a whole species, and not just a single individual.
Explanation:
Charles Darwin gave the theory of natural selection to define the process of biological evolution. This theory states that the individuals of a species with heritable traits that are superior or better suited to their environment will survive, and this process continues over time. This leads to the formation of a new species with the continued process of natural selection.
when looking for the evolutionary effects of the natural selection, one need to look over the selected population over a period of time to see the evolved inherited characters. An individual may or may not have these evolved characteristics, and hence, looking at a single individual of a species will not be a success.
Answer:
A) primary ossification center
Explanation:
Endochondral ossification refers to the gradual replacement of a cartilage model with a bone. The primary ossification center represents the region where bone tissue gradually replaces most of the cartilage model. The deposition of the bone extracellular matrix over the remnants of calcified cartilage is done by osteoblasts. It results in the formation of spongy bone trabeculae. Primary ossification spreads from the central location toward both ends of the cartilage model.
They are different because endocrine glands has tiny amount of hormone directly into the bloodstream . While exocrine glands secret their products on to epithelial
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow

Which cells would you be most likely to find in the dermis?
A dermis is the beneath and upper layer of a cell that makes up the skin. The cells that are found in dermis is fibroblasts and macrophanges, and sometimes white blood cells and mast cells.
Thus, your answer is option D.
Hope I helped (:
Have a great day!
