Given that organisms accumulate contaminants into their bioavailable fractions, we can conclude that the most likely outcome of this pollutant on the oysters is that heavy metals will bioaccumulate in the oysters.

Heavy metals that are often found in water include:

Lead
Copper
Arsenic
Cadmium
Manganese

and more.

Though some metals are water-soluble, this does little to lessen the negative impact of their presence in the water. Water is used as an essential resource for all life. Metals in high concentrations, even those soluble in water, have been shown to be fatal to many organisms, including oysters.

Though oysters would suffer to a degree from biomagnification, which is the accumulation of toxins in an organism through the food chain, this will most likely become a serious problem higher up on the food chain, as the oysters are consumed by predators.

The most likely outcome of these pollutants in the water is that the Heavy metals will bioaccumulate in the oysters. This is due to the fact that the oysters will absorb the metals from the water. At high enough concentrations, this will lead to a decrease in the number of oyster offspring, possibly even reducing it to half.

Before the presence of living organisms earth was a very different place match each fact about about Precambrian earth to the sp

Stolb23 [73]

The correct matches are:

- Atmosphere - Oxygen spilled into this sphere from ocean waters;

The majority of the oxygen in thee Precambrian Earth was not in the atmosphere, but instead it was in the ocean waters. With the emergence of life, large portions of this oxygen went into the atmosphere as it was released as a waste product.

- Biosphere - Cyanobacteria started to emerge as a life form;

The cyanobacteria were one of the earliest life forms. They were producers, and started to use the process of photosynthesis in order to produce food. The usage of this process caused lot of changes on the Earth later on.

- Hydrosphere - Oceans contained far less salt than they do today;

The rocks and minerals in the Precambrian Earth were not weathering and eroding in the manner they are now. Instead they were kept compact for much longer periods, influencing the mixture of of different components with the water as well in meantime.

- Lithosphere - Oxidation in rocks and minerals was not possible;

Because there was way to small amount of oxygen in the atmosphere, very close to 0%, the oxidation of rocks and minerals was not possible, as the oxygen is the gas that causes this process.

lina2011 [118]

Answer:

b. neuron, nerve tissue, brain, nervous system, human

Explanation:

Neurons are the structural and functional units of nervous tissue. Each neuron has a long axon, a metabolic center (soma) and short dendrites. Neurons and neuroglia are the major cell types that together constitute the nervous tissue.

The brain is an organ made of nervous tissues and is a part of the central nervous system. The central and peripheral nervous systems together make the nervous system of the human body.

The nervous system along with many other organ systems such as the digestive system, respiratory system, cardiovascular system, etc. together make the human body.
