The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.
Answer:
D. Chemoautotrophs
Explanation:
Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.
Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.
Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.
Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.
Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.
Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.
Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.
Answer:
the endoplasmic reticulum
Explanation:
it is the endoplasmic reticulum and the ribosomes of the specialized cells in the pancreas that make insulin
The two principles that makes the scientific method a unique process are: The first principle is that events in the natural world have natural causes. The second is uniformity which is the idea that the fundamental laws of nature operate the same way at all places and at all times. Scientific method is the sequence of phases trailed to solve problems as well as collecting data, formulating a hypothesis, testing it and stating conclusions. The scientific method has five straightforward stages and plus one feedback step: 1. Make an statement 2. Ask an interrogation 3. Arrange a testable description 4. Make a forecast based on the theory 5. Test the forecast 6. Repeat the use the outcomes to create new hypotheses or calculations.
