Answer:

i) Rusting occurs the least in tubes 2 and 3 because either of air and water which are necessary for rusting is absent in the two tubes respectively.

ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.

Explanation:

Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.

For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.

In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.

In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.

In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.

In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.

"In order to reconstruct the diet of Neandertals, scientists have analyzed the stable isotopes of nitrogen and carbon in Neander
Virty [35]

Answer:

Big mammals as bears or Mammoths.

Explanation:

Neanderthal had a diet based in different food, for example, there are some evidence that they were feed on nuts, mushroom, and moss. The quantity of veggies were different depending the season and the region of the planet the neanderthals were.  Of course, most of their diet were based in meat, basically  of big animals because the evidence is that they had a digestive system appropriate to eat lean protein.

Studies of the bones and the coprolites showed a ratio of different elements as nitrogen and carbon, the ratio of the heavier element to the lighter, show the relationship among the meat/vegetable diet.

Hope this info is useful.

Which of the following serves as an electron carrier in cellular respiration?
GrogVix [38]

Answer;

-NAD+

Explanation;

-When glucose breaks down into ATP, a large amount of the energy is stored as electron on special molecules (the electron carriers). When an empty electron carrier accepts a pair of electrons, it is reduced; when it gives those electrons up later on, it is oxidized.

-NAD+ and FAD; also the two most common electron carriers in the body. NAD+ can accept a pair of electrons (and a hydrogen ion) to become NADH.
