Answer:

the kidneys excrete salt into the urine when dietary salt levels rise

Explanation:

Hyponatremia is an electrolyte imbalance, with a low level of sodium in the blood. The normal value of sodium in adults is 136 to 145 mEq / L. Sodium is an element, or electrolyte of the blood. Sodium chloride is commonly known as table salt.

Certain conditions can cause decreased sodium in the blood. Specific causes of hyponatremia include:

Water poisoning (water replacement without electrolyte replacement).

Problems in the kidneys, heart or liver.

Medications: such as diuretics, Heparin, certain chemotherapeutics (Aminoglutethimide, Cyclophosphamide and Vincristine).

Conditions related to steroids, hormones or metabolic defects, such as a syndrome that alters the secretion of antidiuretic hormone (SSIHA). If this occurs, you urinate frequently and the kidneys excrete too much sodium. This can result from many conditions, including certain types of lung cancer.

Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to  decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.

Predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein instead
Pani-rosa [81]

Answer:

Since the cell membrane is semi-permeable, the likelihood of substance L entering the cell attached to a large protein is lower than that of substance L free in the culture. Substance L enters the cell membrane through active transport, but the cell membrane may block the larger protein, thus blocking substance L, if it is attached to the large protein.
