The body of water experiences eutrophication.  

The process of eutrophication takes place primarily in ecosystems with gradual changing waters, mainly in deep lakes. In the depths of the lake, where deposition of dead algae takes place, the aerobic bacteria, which feeds on them proliferate that in turn consumes more amount of oxygen.  

Though in the absence of enough circulation of water that is usually found in the case of deep lakes, the bottom of the lake is poorly oxygenated and the bacteria eventually deplete the oxygen found in the deep layers of water. Thus, they can no longer degrade all the dead organic matter and gets accumulated in the sediments. The lake is now considered to be aging.

Which of the following species is diamagnetic? View Available Hint(s) Hint 1. How to determine magnetism Which of the following
m_a_m_a [10]

Answer:

Explanation:

Cl = 1s2 2s2 2p6 3s2 3p5

Al = 1s2 2s2 2p6 3s2 3p1

Fe2+ = 1s2 2s2 2p6 3s2 3p6 4s2 3d4

S2- = 1s2 2s2 2p6 3s2 3p6

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. If all electrons in the particle are paired, then the substance made of this particle is diamagnetic.

S2- is diamagnetic because of its paired electrons in the outermost shell.

Why is it important that we understand and are able to use the metric system?
Artyom0805 [142]
The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:

• SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units. 

• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures. 

• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures. 

• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.

• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.

DerKrebs [107]

Answer:

Its primary role in red blood cells is to maintain levels of red blood cells with low levels of this compound are more suceptible to oxidative damage.

Explanation:

Pentose phosphte pathway helps in the formation of reducing equivalent named NADPH.

  The so formed NADPH is used to maintain a normal cellular level of glutathione which act as antioxidant.

 As glutathione is not mantained in its normal level, it ability to reduce to adverse effect of hydrogen peroxide is cut down.

  As a result cell is more suceptible to oxidative damage.

What happens to the buoyant force of a submerged submarine when water is taken into its tanks and it dives?
Elina [12.6K]

The bouyant force is the capabilty that an object has of floating. Only things that are less dense than water can float on it.

When you bring water inside the submerged submarine nothing happens since the bouyant force only applies to things that float on the fluid we're taliking about.

Answer:

B.


Hope it helped,
