Answer:

See explanation

Explanation:

Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.

Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.

The electrolyte used in the process should be a copper salt e.g CuSO4 solution.

As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.

Which of the following statements is true for glycerol supplementation? Multiple Choice For each kilogram of body weight, athlet
Thepotemich [5.8K]

Answer:

Glycerol-induced hyperhydration will increase osmotic pressure in the body fluids and thus, decrease plasma volume

Explanation:

Glycerol is a metabolite that can be synthesized in the body from glucose and can also be obtained as a food additive. From a biochemistry point of view, glycerol plays a major role with regard to the deprivation of glucose both in aerobic and anaerobic conditions. Athletes use glycerol to delay fluid loss and avoid dehydration during exercise. This metabolite is known to attract water so it stays in the body longer, increasing osmotic pressure and decreasing plasma volume. Glycerol is also used to lose weight and improve exercise performance. Moreover, it is important to note that it has been shown that intravenous injection of glycerol may damage red blood cells (hemolysis).

9. Which of the following is used as evidence for global warming?
KATRIN_1 [288]

Answer:

global glacier mass

Explanation:

<em>The shrink or reduction in the volume of the global glacier mass is one of the evidence of global warming.</em>

<u>By definition, global warming is the rise in global temperature associated with increase in the concentration of greenhouse gases such as carbon dioxide, methane, nitrogen, etc.</u>

The gases naturally form a blanket layer over the earth's atmosphere and are responsible for preventing some of the sun's reflected radiation after reaching the earth from returning back to space. They absorb some of the radiations and warms up the planet in the process.

An increase in the concentration of these gases means that more radiation is absorbed from the sun, thus causing an increase in the amount to warming the earth gets. This increase in the amount of warming is what is termed global warming.

One known consequence of the increase in global temperature as a result of global warming is the melting of glacier mass. Glaciers are prone to melting with increase in temperature and the water derived from such melting are discharged into seas and oceans, causing a rise in their levels.

frutty [35]

Answer: It shows a diagrammatic representation of biomass at different tropic levels in an ecosystem

Explanation:

Goat eat grass. The goat are in turn eaten by the Man. The grass has the greatest biomass in this chain. Its biomass, therefore, sits at the bottom of the pyramid. Conversely, the man has the lowest biomass in the chain and hence sits on top of the pyramid.

Lyrx [107]
#1. it got transported by humans
#2. They were intentionally transported
#3. the reason that they were transported was because humans mainly got them for their fur and for food + they also had no prederters only foxes so humans had a good supply of food and rabbit hide for clothing also rabbits breed quickly so the population can go up 2,000 in a week!



Hope this helps!!!
