Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. Biston betularia, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

Answer:

Natural selection is a theory originally popularized by Charles Darwin. According to this theory, animals in the natural environment change over time as beneficial traits are preserved, and traits which do not advance the species are slowly weeded out. Natural selection, a concept first theorized by Charles Darwin, is the adjustment of genes throughout generations based on factors that help it survive. Sometimes this is survival of the fittest or the organisms that are better suited to the environment in other ways.

The suitable option will be - B

Citric acid cycle

Explanation:

The results were -

Glucose: None

CO2: Increase

O2: None

ATP: Increase

NADH: Increase

We know that the Citric acid cycle is also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle. This cycle occurs in Mitochondria in case of eukaryotes. In this cycle acetyl-CoA is oxidized which comes from carbohydrates, proteins and fats and energy is released in the form of ATP.

water is also used in this process. NAD+ gets reduced to NADPH. In this system carbon dioxide is produced as a waste byproduct. ATP is produced as the main product. ATP is also used as a source of energy.

The term for energy of movement

lara31 [8.8K]

Answer;

-Kinetic energy

Explanation;

The energy associated with motion or movement is called kinetic energy.

-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.

-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.

-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
