Answer:
Supportive connective tissue—bone and cartilage—provide structure and strength to the body and protect soft tissues. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. In bone, the matrix is rigid and described as calcified because of the deposited calcium salts.
Explanation:
C. Energy processing from corn biofuels is not energy efficient.
we have been evolved through same root, during the process we get separated and develop new features to adjust in the surrounding atmosphere, that's why our genes are matching with fruit flies and others.
Answer:
The mouse and chicken have the closest relationship of the 5 presented because they have the most shared characteristics through their embryonic development. 3. Why do you think scientists study the embryological development of different species?
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
