Answer:
5 chromosomes.
Explanation:
Monosomy is a term used when only one copy of a chromosome is present, instead of the usual pair. If mosquitoes have 2n=6 chromosomes, an adult mosquito with monosomy will have only one chromosome in one of its pairos giving a total of 6-1=5 chromosomes

Answer:
Evolution in nature by natural selection only modifies the structures present in the ancestors and favors the better adapted structures.
Explanation:
An engineer can design the bones and muscles of the forelimbs of given organisms as per their needs and give rise to new unique structures for each of these organisms.
On the other hand, evolution in nature allows the modification of existing traits by the accumulation of variations. The adaptive variations in the traits are then favored by natural selection. Therefore, forelimbs of mammals such as horses, whales, and bats have evolved by modification of the forelimbs present in their common ancestors.
The limitation of modification of existing structures does not allow the formation of a completely new structure.
Answer:
C. Moving a bone back and forth requires the action of at least two muscles.
Explanation:
To move bones in opposite directions muscles must pair up to help move the body part.
The carnivore population would also increase because there would be a
larger food-source for carnivorous so more of them would be able to
survive.
The carnivore population would go up as well because they have more food
(herbivores) to eat. There would be more food to sustain the carnivore
population.
Answer:
The correct answer will be option- Glycolysis.
Explanation:
Gluconeogenesis is a metabolic pathway which synthesizes glucose from non-sugar precursors. This pathway is activated in the low concentration of glucose due to less intake or completely absent to conserve energy.
This pathway is somewhat the reverse of the glycolysis when excess energy is present as a result of glycolysis, gluconeogenesis is inhibited and when no energy is present, gluconeogenesis is activated.
Thus, option- glycolysis is the correct answer.
