Answer:
b. Reinforcement is a type of natural selection.
c. Reinforcement decreases the morphological difference between two incipient species.
d. Reinforcement is also called dispersive selection
The statements about reinforcement is true is that Reinforcement decreases the morphological difference between two incipient species.
Option C is correct.
Reinforcement is described as a type of natural selection that occurs when two populations that are becoming reproductively isolated from each other start to develop preferences for mates from their own population.
This can lead to a decrease in the morphological difference between the two populations, as they become more adapted to each other's mating preferences.
In conclusion, reinforcement is a type of natural selection, not the other way around. Option d is incorrect because reinforcement is also called assortative mating, not dispersive selection.
Therefore option B is correct

The Krebs Cycle occurs in the matrix of the mitochondrion of a eukaryotic cell, which is a part of the process of cellular respiration, generating energy for the cell.
The Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid (TCA) cycle, takes place in the matrix of the mitochondrion of a eukaryotic cell. This cycle is a crucial part of cellular respiration, the process by which cells generate energy. During the Krebs cycle, the pyruvate molecules derived from glucose are oxidized and, in turn, produce ATP (adenosine triphosphate), the main source of cellular energy, and other high-energy compounds. The matrix of the mitochondrion provides the necessary environment and enzymes for this cycle to occur effectively.

b. thymine and guanine
c. adenine and guanine
d. adenine and cytosine
B. Anopheles quadrimaculatus
C. Ades aeqypti
D. Aedes sollicitans
Anopheles punctulatus is most closely related to Anopheles quadrimaculatus according to the binomial classification system, because they belong to the same genus.
In the binomial classification system, organisms are named based on their genus and species. In this case, Anopheles punctulatus and Anopheles quadrimaculatus are both part of the Anopheles genus meaning they share a lot of similarities in term of structure and genetics. Therefore, Anopheles punctulatus is most closely related in structure to Anopheles quadrimaculatus.
Clux pipiens, Ades aeqypti, and Aedes sollicitans are species from other genus, hence they are not as closely related. Although they are all mosquitoes and have certain common features, they do not share as many similarities as within the same genus. Hence, Anopheles punctulatus has compared to other options, the most similarities with Anopheles quadrimaculatus.

-0.372 g/cm3
-2.69 g/cm3
-4.24 g/cm3
Density = 2.69 g.cm⁻³
Data Given;
Density = ??
Mass = 37.1 g
Volume = 2.0 cm × 5.5 cm × 1.25 cm = 13.75 cm³
Formula Used;
Density = Mass ÷ Volume
Putting values,
Density = 37.1 g ÷ 13.75 cm³
Density = 2.69 g.cm⁻³
