What is water pollution?

Biology
2 answers:
AysviL [449]2 years ago

Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems.

The diet of a Triggerfish includes sea urchins overtime the increase use of recreational boats in areas inhabited by Triggerfish
Anastasy [175]

Answer:

D. decreasing in population.​

Explanation:

Triggerfish are the brightly colored fish and sea urchins are the globular animals, echinoderms. Triggerfish eat sea urchins for their survival.

An increase in the use of recreational boats over the area will damage the habitat of the triggerfish and also affect their food supply, it will result in a decreasing population of triggerfish. Due to lack of sea urchins and habitat disturbance, the Triggerfish population will decrease

Hence, the correct answer is "D. decreasing in population.​"

Peroxidase is an enzyme that breaks down hydrogen peroxide in cells. It accomplishes this because of its structure. What part of
statuscvo [17]

Answer:

The answer is a heme cofactor.

Explanation:

Peroxidase is an enzyme that catalyzes oxidation/reduction reaction by using hydrogen peroxide as a substrate.  

Donor+H2O2 ↔ Oxidized donor + H2O

Peroxidase active site can contain a heme cofactor that has an iron ion and a porphyrin molecule that acts as an electron donor to the hydrogen peroxide which is then reduced to water.

Which of the following represents an isotope for lithium (73Li)?
NARA [144]

Answer:

The correct answer is - option b) 3Li .

Explanation:

Lithium that is occurring naturally have two isotopes that are stable one with an atomic mass of 7 and the other with an atomic mass of 6 both have the same atomic number.

In question 7(atomic mass) 3 (atomic number) is given and there is only two option have 3 atomic number with 3 b) 3.Li and d) 43Li. 4 atomic mass is not naturally occurring isotopes and as option b) has a no atomic mass so it would be the correct answer.

Thus, the correct answer is - option b) 3Li .

The rate of a typical enzymatic reaction is increased by which of the following changes?A. Decrease substrate concentrationB. In
galben [10]

Answer:

D. Increase in temperature from 20 degrees C to 37 degree C

Explanation:

A decrease in substrate concentration might not necessarily lead to an increase in enzymatic activities.

Enzymes are pH specific. Thus increasing the pH of operation from 6.8 to 7.4 might destroy the enzyme.

Reactants need to overcome a minimum energy (activation energy) before they can be converted to products. The higher this energy, the lower the rate of reaction. Hence, increasing in activation energy will lead to a lower rate of enzymatic reaction.

<em>Enzymes work optimally at a temperature that is close to the human's body temperature which is 37.5 degrees. Hence, increasing temperature from 20 degrees to 37 degrees will result in an increased enzymatic activities.</em>

The correct option is D.
