Answer:
The correct answer is option d. "Its conformation will change when both an ion and a small molecule bind to it".
Explanation:
The secondary active transport is a form of active transport at which a ion (typically Na+ or H+) is transferred down its electrochemical gradient to the uphill movement of another molecule. Secondary active transport takes place by the conjunctive work of membrane-bound proteins and sodium–potassium pumps. During secondary active transport, both of these proteins change its conformation when an ion and a small molecule bind to it. This change in conformation makes possible that the ions and the small molecules pass through the membrane.
At times, a person may have experienced a sudden or unexpected change in body temperature within a 24-hour period. This change in the body temperature is caused by immune responses. If there is a detected infection in the body, the immune system fights back thus causing the change of body temperature.
Answer:
they use to live
Explanation:
As they breath out carbon dioxide the plants take in the carbon dioxide and make air with it. Animals also use air to do their day to day things like eat.
