Answer:

The wise use of crop genetic diversity in developing improved crops can contribute significantly to protecting the environment. Crop varieties that are resistant to pests and diseases can reduce the need to apply harmful pesticides. More vigorous varieties can better compete with weeds, reducing the need for applying herbicides .

imagine that you are called in to investigate a body that was found in a fire. What evidence would you look for to determine if

A body subjected to fire effects can tell the investigator about the fire (and/or explosion), as well as about what occurred before, during, and after the fire. These facts may be crucial to fire origin and cause determination, as well as responsibility and motive in an incendiary fire.Fire injuries and deaths can be related to other crimes, including arson, homicide, and robbery.When investigating a scene, it is not possible to know if, and when, the case may come to civil and/or criminal trial. It may be years before the fire investigator is called to testify, therefore it is imperative to document properly and process evidence properly so the case can be recalled years later and successfully follow the judicial process.More than other fires, fatal fires can create substantial media interest and scrutiny of the investigation by outside parties. The investigative methods and actions must stand up to this scrutiny.

Proteolytic enzymes secreted from the pancreas are activated: a) within the lumen of the small intestine. b) once they reach the

Aneli [31]

Answer:

A) within the lumen of the small intestine.

Explanation:

The pancreas produces a variety of hormone-like amylase, proteases, lipases which can digest the food material.

The proteases like chymotrypsinogen and trypsinogen are produced by the pancreas in their inactive form as if active will digest the organ itself. Therefore these zymogens are stored in the secretory vesicles which release the enzymes in the pancreatic duct.

These zymogens are not activated until they reach the digestive tract that is when these enzymes enter the lumen of the small intestine, the enterokinase present there catalyzes the trypsinogen to trypsin. Trypsin converts the chymotrypsinogen to the chymotrypsin.

Thus, Option-A is the correct answer.

Please I need help with this question ASAP:

frosja888 [35]

Answer:

Explanation:

After having a carbohydrate rich meal concentration of some hormones, especially insulin change in your body. Insulin promotes the uptake of glucose by cells(particularly muscle cells, adipocytes, liver cells). It also increases the rate of glycolysis and glycogenesis and decreases the rate of gluconeogenesis and glycogenolysis.

These important metabolic pathways cause burning up glucose to make ATP that all cells in our body need and also storing it in the form of glycogen in the liver which is a very important food storage. Metabolism of carbohydrates also causes fat to be deposited in adipocytes which is basically why we have stuff like keto diets(no or very little carbohydrates and mainly fats consumed) for losing weight!
