Answer:
Earth and space science explores the interconnections between the land, ocean, atmosphere, and life of our planet. These include the cycles of water, carbon, rock, and other materials that continuously shape, influence, and sustain Earth and its inhabitants
Explanation:
The correct answer is the immune system, more specifically, the thymus gland. The thymus gland, while it produces hormones like thymosin, it is more closely related to the immune system rather than the endocrine system. This is because lymphocytes that go into the thymus gland mature into T lymphocytes that can either be a helper T cell or a cytotoxic T cell, depending on the stimulus.
Fractional distillation is the process in which the alkanes in petroleum can be partly separated. This is due to the petroleum having different boiling points. The process starts off with the heating of crude oil for it to vaporize. The vaporized crude oil is then fed into the bottom of the distillation tower. The resulting vapor rises through a vertical column. As the gases rises through the distillation tower, its temperature decreases. Thus, certain hydrocarbons begin to condense and run off at varying levels. Each level-specific condensed fraction contains hydrocarbon molecules that has a similar number of carbon atoms. These "cuts" of boiling point allow numerous hydrocarbons to be separated out in a single process. The cooling of the tower height allows for the separation. Subsequent to the refinement, individual fuels may undergo more refinement to remove existing contaminants or substances so as to improve the quality of the fuel through cracking.
The roles fulfilled by the males increase the survival of the species is males scare off predators and protect the pack.
<h3>What does fittest animals mean?</h3>
According to natural selection, there is a constant struggle for survival and only the fittest organisms are selected. These fitter organisms would be able to pass on their advantageous traits to their descendants.
Generally the main factors that cause the destruction of a habitat are deforestation, fires, livestock, agriculture and human occupation. Don't stop now.

Answer:
Sugar
Explanation:
The correct answer would be sugar.
Respiration generally involves the metabolic breakdown of carbohydrates to generate energy (in the form of ATP). It is a multi-step process that can summarily be represented by the equation below:
<em>As a rule of thumb, the higher the respiratory quotient of a substrate, the higher the energy that will be generated if such a substrate is utilized for respiration. By definition, the respiratory quotient of a substrate is the ratio of carbon dioxide to oxygen produced or consumed to breakdown the substrate.</em>
Carbohydrates are known to have the highest respiratory quotient while other molecules follow in varying degrees. Other substances apart from carbohydrates have to undergo one or two metabolic processes before they can enter the respiratory pathway, thereby reducing their efficiencies when compared to carbohydrates.
