Water, sunlight, and carbon dioxide
Answer: 3 stages- glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+. A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA. The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.

Answer:
The correct answer is ecological isolation.
Explanation:
The condition when two species in spite of living in the same region, exhibits certain characteristics, which inhibits them from mating with each other is termed as reproductive isolation. The obstructions or the causes that prevent them from interbreeding is known as isolating mechanisms.
The given case is an example of ecological isolation and is one of the forms of reproductive isolation. Habitat or ecological isolation refers to the phenomenon in which two species cannot mate with each other as they thrive in two distinct locations. Like as mentioned, two species of garter snakes though coming from the same geographical area cannot interbreed, as one of them is living in the land and the other one in the water.
Answer: Bacteria gain resistance to drugs because of mutations (permanent and random changes to their DNA) which means they have changed DNA coding, giving them the ability to resist the drug fighting them off. As a result, they survive and reproduce. Over time, more and more bacteria are generated as the DNA code for resistance is passed on over generations. This results in bacteria having the ability to resist drugs. This is particularly prevalent with antibiotics.
