What might happen if some lysosomal enzymes are absent?​
murzikaleks [220]

Answer:

Explanation:

The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.

These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.

WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:

==> If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.

==>build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.

==> absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.

==> Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.

Shana is a competitive athlete who weighs 135 lb. she would like to plan a nutritionally adequate diet that provides enough carb
prisoha [69]
The correct answer is d.

Carbohydrates are a very important part of an athlete's diet, since they provide the necessary energy for competition and endurance, but also help in the process of muscle gain.

The amount of carbohydrates that Shana should consume depend heavily on the intensity of her exercise activities. For a moderate level of exercise, which equals to 1 hour of exercise daily, a person should consume 5-7 g/kg of body weight. For a high level of exercise (1-3 hours of daily exercise), a person should consume 6-10 g/kg.

Guessing that Shana will perform a high level of exercise and based on her weight (135 lb or 61.2 kg), Shana should consume 366 to 610 g of carbohydrates daily.

Investigators have arrived at a crime scene and are ready to search for evidence. What needs to happen next?
denpristay [2]

Answer: C . They should map out a grid to systematically look for evidence.

Explanation:

As a crime has been committed, the investigators do not need a search warrant so there is no need to ask a Judge for one so option A is incorrect.

It is best if evidence is searched for in different locations not just the primary scene so option B is incorrect.

Setting up a grip to enable the systematic analysis of evidence is their most likely course of action so option C is correct.

Even if the case is not complicated, evidence still needs to be searched for so option D is wrong.
