Answer: Aquifers that are drying up are mainly near arid climates, large cities, or agricultural stations, like farms.if the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water Excessive pumping can lower the water table so much that the wells no longer supply water they can "go dry."

Cyanide binds to Fe3+ in heme-containing proteins. This inhibits the terminal cytochrome complex IV of the electron transport chain. The blocklock of complex IV by cyanide depletes ATP culminating in cell death. Oxygen is unable to reoxidize the reduced cytochrome a3. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. Hypoxia evolves into metabolic acidosis and decreased oxygen saturation. The extent of lactic acidosis indicates the severity of the cyanide poisoning. In a collapsed individual, plasma lactate is an indicator of cyanide poisoning. In severe cyanide poisonings, up to 98% of the cyanide in the bloodstream is tightly bound to red blood cells. The ancillary response is myocardial depression and decline in cardiac output. Bradycardia, hypotension, and cardiac arrhythmia then develop into VF and cardiovascular collapse.

Answer:

B

Explanation:

Answer:  

Trackways/footprints, mold and cast fossils, feeding marks, coprolites, and burrows. Trace fossils show the activity of ancient organisms rather than the body fossil itself. However, it is rather difficult to identify an organism by use of mere trace fossil, and therefore, it is less accurate.

Answer:

See explanation

Explanation:

A precipitate is formed when a mixture of two soluble substances results in the formation of an insoluble product. It usually happens during a double decomposition reaction.

The two clear liquids combined both contain soluble substances. These interact to yield an insoluble product also known as a precipitate which is black in colour and settles on the bottom of the beaker.

Answer:

Mutation causes brand new alleles the others just modify the rates at which preexisting alleles appear in the population.

Answer:

Implantation is the mechanism by which a blastocyst, which is passing through the uterus as a developing embryo, makes contact with the uterine wall and remains bound to it before birth. The uterine lining (endometrium) undergoes several internal modifications in order to allow for the emerging blastocyst to bind to it.

secondary succession

Explanation:

Hi there!

I think the answer would be a protist that is a heterotroph and has chlorophyll. The protist falling under this category is called Euglena. Euglena has the ability to synthesize food using its chlorophyll, but if the light gets scarce it can utilize its heterotroph qualities and catch food instead.

Answer:

Although sponges do not have organized tissue, they depend on specialized cells, such as choanocytes, porocytes, amoebocytes, and pinacocytes, for specialized functions within their bodies. The mesohyl acts as a type of endoskeleton, helping to maintain the tubular shape of sponges.
