In this discussion, you will justify the dependence of life on the sun and the interdependence of living things and their chemis
Deffense [45]

Answer:

1. The species that can produce their food with the assistance of light energy coming from the Sun are termed as autotrophs. These species tend to produce chemical energy from light energy. Heterotrophs on the other hand refer to the species that lack the tendency of generating their food and are solely reliant upon the autotrophs for food.  

2. The phenomenon that utilizes water and carbon dioxide and produces carbohydrates within the plants is known as photosynthesis. In the process, oxygen is also produced as a byproduct. The produced oxygen is further utilized by other species in the process of cellular respiration.  

3. In the life of an organism, both oxidation and reduction perform an essential function. In the process of photosynthesis, the reduction of carbon dioxide is done and oxidation of water molecules is done. Therefore, it can be said that photosynthesis is an illustration of the oxidation-reduction reaction. Similarly, in cellular respiration, the molecules of oxygen are reduced and the molecules of glucose are oxidized, thus, it is also an illustration of an oxidation-reduction reaction.  

4. In the light reaction phase of photosynthesis, the production of ATP, that is, the source of energy is done. Further in plants, the utilization of ATP is done to fix carbon dioxide within the glucose. In the process of cellular respiration, the energy within the carbohydrates is utilized to generate ATP at the time of the electron transport chain.

If a cusp is lost during preparation, which matrix band would provide the best support while restoring
Grace [21]

Answer:

I would use a specialized or preformed matrix for the posterior sector.

Explanation:

Losing a cusp is a much more critical situation, that is, there will be less tooth remnant and less resistance to functional and parafunctional forces.

The matrices that are usually used in the posterior sector are matrices that must be burnished and already come with a format to better restore the functional unit of the occlusal surface.

It is important to clarify that cusps are only in the posterior sector and not in the anterior sector.

The cusps, even if they have the most correct selection of the matrix, will fail in their restoration if they are not performed according to the patient's occlusion, under a good dental integration system such as adhesion through resins, and respecting the normal antomy of the piece to be restored.

A species that is said to be polytypic is a species
mezya [45]

Answer:

c. wtih physically differing populations which can still successfully reproduce

Explanation:

Polytype is when a single species has many variations in its area of coverage, it is thought that they are distinct species, or when many varieties or breeds of the same species are produced, as in the Lobos, which is naturally already polypic, and many dog breeds are still bred within the subspecies Canis lupus familiaris. In other words, we can say that in a polytyp species, many individuals have very different physical characteristics, but are of the same species, so they can reproduce successfully.
