Answer:
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
The answer is "PET scan" or "PET-CT".
PET scan or positron emission tomography uses the technology behind conventional CT scans but performs to quantify the function in specific parts of organs (i.e. brain). The patient will be given a positron emitting substance most commonly fluorodeoxyglucose or FDG via intravenous injection. After which, the patient will go to the PET machine and the PET machine will measure the positron emitted throughout the body. Positron is well correlated to the function of a specific part of an organ.

Answer:
All living organisms reproduce sexually
Explanation:
Not all living organism reproduce sexually. Plant and animal are also living organism but not all plants reproduces sexually. We have sexual and asexual reproduction in plant
Plant reproduce sexually through the fusion of male and female gametes followed by fertilization to produce an offspring. Offspring produce through sexual reproduction have both maternal and paternal makeup.
Asexual reproduction includes binary fission, budding, grafting. It is the production of the exact kind of the parent plant, it does not require fertilization and the parents and the progeny are 100% identical.
Answer:
<em>The correct option is D) the natural extinction rate</em>
Explanation:
Extinction can be described as a process due to which species get removed from the world.
Background extinction can be described as the standard rate of extinction of organisms of a species due to ecological or environmental factors. It is a low-level type of extinction which occurs over a long period of time. It can be described as the natural extinction rate of individual organisms. Hence, option D best describes the natural phenomenon of background extinction.
