$\huge\mathcal\green{answer}$

Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.

When a substance abuse treatment program is acquired by another program, what is the the next course of actions?

Bezzdna [24]

When a substance abuse treatment program is acquired by another program, the next course of action is that if any patients refuse consent to transfer, those records maybe destroyed or retained in compliance with the statue of limitations

Explanation:

The Substance Abuse Confidentiality Regulations devised by the Substance Abuse and Mental Health Services Administration provides confidentiality to the patients undergoing a treatment program for substance abuse.

Under this regulation, section 2.19 details and sets forth rules to follow when a program is acquired by another program.

This states that the program must either purge the identifying details of the patient from its records or destroy it until or unless the patient consents for the transfer of details or information in the records.

This condition can be exceptional in compliance with the statute of limitations and the records can be retained, like in case of any legal requirements .
