Answer:
I'm pretty sure its a neuron
The answer is; DNA helicase
They unzip the double helix into single strands during replication. The unzipping occurs at regions called origins where replication is initiated. The protein breaks the hydrogen bonds (using energy from ATP) between the complimentary bases of the strands hence forming a replication fork.
Answer:
10 grams of fat.
Explanation:
The four important biomolecules are protein, carbohydrate, fat and nucleic acid. These biomolecules are used for the genereation of ATP in living organisms.
The largest amount of energy is produced by fat as compared with proteins and fats. Hence, 10 grams of fat produce largest amount of energy.
Thus, the correct answer is option (1).
Answer:
Evolution
Explanation:
Evolution is the change in habits, hereditary and physical characteristics of a species over various generations in response to environmental conditions. Evolution lead to adaptation, the nature selection of the fittest and elimination of remaining.
Evolution may produce variety and diversity in response to mutation, genetic drift and other genetic variation. These changes may pass to offspring and may express them more in one group of population.
Evolution also explain the unity among organisms by explaining their shared characteristics. This refers to their common ancestors.
The correct answer is stabilizing selection.
Stabilizing selection is a kind of natural selection in which the mean of the population steadies on a specific non-extreme trait value. This is considered to be the most general process of action for natural selection as the majority of the traits do not seem to vary radically with time.
Stabilizing selection is the reverse of disruptive selection. In spite of preferring individuals with extreme phenotypes, it favors the transitional variants. Stabilizing selection seems to eradicate the more extreme phenotypes, resulting in the reproductive success of the average or norm phenotypes.
This signifies that the most general phenotype in the population is chosen and continues to govern in the coming generations. As the majority of the traits vary slightly with time, stabilizing selection is considered to be the most usual kind of selection in the majority of the populations.
