Answer:
All the organisms (plants and animals) require energy for performing various activities and maintaining their life. This energy is obtained by the breakdown of digested food during the process of respiration. The process of releasing energy from food is called respiration.
Most energy comes from the sun, either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat those plants to obtain energy. Carnivores eat the herbivores, and decomposers digest plant and animal matter.
Two ways that living things get their energy is by, Cellular Respiration and Photosynthesis.
Cellular Respiration: Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Photosynthesis: it's process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by product.
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

A) Genetic drift is the random increase or decrease of genes in a population. Natural selection is not random.
Genetic drift is the change in the frequencies of alleles in a population due to chance events (random survival). Genetic drift exhibits strong effects in small populations and plays a smaller role the larger the population gets. Natural selection is the non-random change in the frequency of alleles in a population over time, because the change in frequency of the alleles is dictated by the different relative fitnesses that different alleles confer.

Answer.Nucleotides Have Characteristic Bases and Pentose. Nucleotides have three characteristic components: (1) a nitrogenous base, (2) a pentose, and (3) a phosphate (Fig. ... The nitrogenous bases are derivatives of two parent compounds, pyrimidine and purine (Fig. 12-lb).
