Answer:
Once a vital plant that many humans or animals need go extinct, many of them will die due to starvation and or shelters they build might not be able to be built due to the extinct plant being gone. As an example, If trees went extinct, humans wouldn't be able to live. One, because trees help filter the air for us humans to breath, wood is a very vital supply too. Wood is used for paper, homes, and even appliances.
Explanation:
Answer:
decrease kisspeptin synthesis
Explanation:
Kisspeptin is a protein involved in the regulation of gonadotropin-releasing hormone (GnRH): it stimulates the secretion of GnRH. GnRH than stimulate the release of gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. FSH stimulates the production of estrogens by the granulosa cells of the ovarian follicles.
In negative feedback system, high levels of estrogen will bind to their receptors on neurons that release kisspeptin and inhibit its further release.
Acid-Fast Bacteria possess a unique cell wall architecture different from both gram negative and gram positive bacteria. The thick outer mycolic acid layer renders acid-fast bacteria resistant to gram stain.
The answer here is B.
The person is doing a literature search. They are looking up existing data. They’re not actually doing an experiment that will generate new data. Observational studies and controlled experiments have different study designs but both ultimately generate new data.
