Species richness increases as we travel southward from the North Pole.
Explanation:
Species richness is at its highest in places near or surrounding the equator and reduces gradually towards the poles. As one travel towards south from the northern pole, the temperate, tropical and equatorial regions will be reached where there is huge diversity of species.
Be it the tropical rain forests, the Amazon forests, or the deciduous forests, they are highly rich in their species population and variety. This is mainly due to availability of favorable conditions like weather, temperature, rainfall, etc which favors their growth and reproduction. Numerous phyla or classes of species can be found in such equatorial belts rather than in the north or the south pole.
Elevation gradient also plays an role in species richness.
Answer:
d. raise the apparent value of the equilibrium constant, L.
Explanation:
Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.
Answer: A). cause the three bones of the middle ear to begin to vibrate.
Explanation: Sound is transmitted as waves from the outer ear through the ear canal to the ear drum. The sound waves causes the eardrum to vibrate and consequent vibration of the three tiny bones of the middle ear. The vibration of the three tiny bones causes the fluid in the inner ear to vibrate. The vibration of the fluid causes the tiny hairs to vibrate and and the vibration is converted to electrical impulses that are transmitted to the auditory nerve and to the brain, where they are intepreted as hearing (sound).
Answer:
Darwin's discussion of bird species on the Galapagos islands relates to natural selection because the finches all have a recent common ancestor, but they evolved on different islands with different types of food, so the birds that weren't fit enough to survive the island conditions died, and the ones that did were "naturally selected."
Explanation:
The finches all have a recent common ancestor but they evolved on different islands where different types of food are available. During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants. Among those that struck Darwin so greatly were the finches that are now named in his honor.
