Answer: the answer would be snythesis (d)
Explanation:
Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.
Explanation:
Discuss Sutton’s Chromosomal Theory of Inheritance
Describe genetic linkage
Explain the process of homologous recombination, or crossing over
Describe how chromosome maps are created
Calculate the distances between three genes on a chromosome using a three-point test cross
Long before chromosomes were visualized under a microscope, the father of modern genetics, Gregor Mendel, began studying heredity in 1843. With the improvement of microscopic techniques during the late 1800s, cell biologists could stain and visualize subcellular structures with dyes and observe their actions during cell division and meiosis. With each mitotic division, chromosomes replicated, condensed from an amorphous (no constant shape) nuclear mass into distinct X-shaped bodies (pairs of identical sister chromatids), and migrated to separate cellular poles.
Answer:
<em>"The limb bones are similar across these species because they share a common ancestor </em>is a right option.
Explanation:
Forelimb (humerus, ulna, and radius) is a homologous structure in all vertebrates. This means that these structures are evolved from the same lineage. Homologous organs could perform different functions but they are structurally similar.
If there is any similarity in different animal's forelimb structure (e.g. horses, goats, and mice), then they are considered to be of same evolutionary origin. Their structures are similar but not function. Evolutionary biology tells us that homologous structures are adapted to different environments as a result of modifications from a common ancestor.
In a nutshell, forelimbs of ancestral vertebrates have evolved into the running forelegs of mice, goats and horses, and the grasping hands of humans.
