Answer: enable them to imprint on the facility

Explanation:

The addition of the chemicals to the river will help the fishes to recognize that this was their native habitat where they got birth and grew. This will act as a imprint formed by the facility which will help the fishes to recognize the water of the facility. This will help in increasing the number of fishes which return back to the facility.

Answer:

reduction in potential medicines

reduced food supply

Explanation:

The direct consequences of a decrease in angiosperm's biodiversity is a reduction in potential medicines and food supply.

Angiosperm biodiversity (the flowering plants) act as a source of food to several living organisms, including human. This is evident in the practice of farming by humans. Different categories of consumers in the ecosystem depends largely on flowering plants for their food either directly or indirectly.

They also serve as a source of medicine. For example, chloroquine which use to be the major drug against the treatment of malaria was extracted from a flowering plant known as <em>Chinchona pubescens.</em>

<em>Several species of flowering plants remains in the wild whose usefulness are yet to be researched. They represent a source of future food and medicine for man and animals.</em>

<em>Hence, if the diversity of flowering plants is reduced, it is going to have direct consequence of reduction in potential foods and medicine.</em>

bicarbonate ions in blood can absorb hydrogen ions, keeping pH balanced. bicarbonate is acting as a ________  in blood?
Veseljchak [2.6K]
Buffer is an aqueous solution that resists changes in pH when acids or bases are added to it. A buffer solution is typically composed of a weak acid and its conjugate base. There are three major buffer systems that are responsible for regulating blood pH: the bicarbonate buffer system, the phosphate buffer system, and the plasma protein buffer system. Of the three buffer systems, the bicarbonate buffer system is arguably the most important as it is the only one that is coupled to the respiratory system

A stream of water holds thriving bacteria. If drought conditions caused the stream to dry up, how would the bacteria mostly like
Alexeev081 [22]

The answer is they produce endospores.

Explanation:

The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.

During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.

Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.
