Explain why enzymes affect specific types of reactions.

1 answer:

4 0

Enzymes are made of proteins that are capable of catalyzing a reaction in which various substrate are converted to products through the formation of an intermediate enzyme-substrate complex. It hastens reactions and acts as a catalyst without themselves undergoing permanent chemical changes. The catalytic ability of enzymes is due to its particular protein structure.

How might increasing the energy efficiency of a home might lead to increased radon levels indoors?

mars1129 [50]

Improving energy efficiency of a home generally means reducing the exchange of outdoor air (ventilation) with indoor air that can be contaminated with radon gas.
Explanation:
The presence of radon gas is not detectable by humans. It is odorless, colorless, tasteless, and radioactive. It can cause lung cancer over time and quantity breathed in. It enters buildings through cracks and voids in their foundations from the soil surrounding them.
The energy efficiency of buildings has been steadily increasing as we try to conserve energy and reduce costs. By so doing we also reduce the airflow between inside and outside, especially during the colder months of the year.
This practice will result in radon gas concentration buildup to values that could become unsafe for human consumption.
There are a number of methods to reduce the threat of radon gas in a house, but first there needs to be a measurement of the level of gas in the building. If the threat is high, the radon gas must be removed.

Alveoli are most likely to collapse (resulting in atelectasis) when which condition exists

Marrrta [24]

Atelectasis: Atelectasis is a complete or partial collapse of the entire lung or area of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. . General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.

Conditions when atelectasis occurs: There are four primary causes of atelectasis: hypoventilation, airway obstruction, airway compression, and adhesions.

Hypoventilation

Hypoventilation, or breathing at an abnormally slow rate, is common during surgery, especially with general anesthesia, or when a person is placed on a respirator. The very act of shallow breathing prevents air from getting to the alveoli, causing the air sacs to deflate and collapse.

Airway Obstruction

Airway obstruction may be caused when something blocks a passage either inside the lung (like a mucus plug or a foreign object) or outside of the lungs (like a tumor which presses on the airway and causes obstruction).

Airway Compression

Compression of the airways is often caused by the buildup of fluid in the space surrounding the lungs.

Having freckles is dominant (F), and not having freckles is recessive (f). A mother has Ff and a father has ff. If they have a c

Savatey [412]

D is the correct answer. The child with no freckles would have to have two little f's, or have two recessive alleles to not get the freckles. If there is FF or fF or Ff, since there is a dominant allele, the child will have freckles.
