What are the reactants in the equation for cellular respiration?

The reactant are oxygen and carbohydrate (glucose).

Cellular respiration is a redox reaction that extracts energy from glucose. We will have a controlled release of the free energy of organic compounds from the cells to form ATP.

Can be done in the presence (aerobic) or absence (anaerobic) of oxygen.

The aerobic reaction will produce carbon dioxide (CO2) and water (H2O).

<u>Answer:</u>

Heat moves from the land to the air through the process of "conduction".

<u>Explanation:</u>

When the two things come in contact with one another at different temperatures or basically when heat flows from the warmer to the colder region or phase until both reach at the same temperature is understood as "conduction". Conduction is a physical process which occur by collision of the microscopically colliding particles like molecules, atoms and electrons on the movement of heat through a substance.

While convection take place by the movement of heated objects and it isn't the process influencing air and water temperature difference. The examples of conduction are like a radiator, a heating pad, sand can conduct heat etc.

Consider a series of metabolic events during fasting. Within a few days after a fast begins, nitrogen excretion accelerates to a
timurjin [86]

Answer:

A series of events occur, in prolonged fasting; the body undergoes changes and adaptations of its metabolism to continue to meet energy needs and maintain vital functions, despite not receiving food

These changes are divided into three phases according to the elapsed days of fasting and according to the metabolic processes involved.

First phase: main consumption of reserve carbohydrates.

Second phase: main consumption of fats.

Third phase: serious consumption of proteins.

Explanation:

If the fast is prolonged in time, the metabolic processes change in their qualitative and quantitative characteristics, so that the energy products consumed (glucose, free fatty acids and ketone bodies) are modified, their oxidation decreases globally and after the initial depletion of hepatic and muscular glycogen and protein catabolism, the main source of glucose is the liver through gluconeogenesis. The substrates initially come from protein catabolism and lipolysis, but later protein destruction slows down, maximizing lipolysis.

Between the first phase and the second phase of the fast some muscle proteins are lost but not excessively, even with fasts of two or three weeks.

After about 2 weeks of fasting, up to two-thirds of the energy the brain needs is obtained from ketone bodies. These ketone bodies are the breakdown products of fats and are responsible for the typical ketone breath reminiscent of the smell of acid apples; urine also smells like ketone.

In this phase, damage begins to occur in some important organs such as the liver and kidneys. Starting the first week of fasting, acidosis affects the heart's function of the circulation and the brain.

In the third phase of the prolonged fast it happens from 3 weeks, that is, about twenty days without food, although it varies according to the constitution of each person. A peak of muscle protein consumption occurs and a great loss of weight begins to be perceived with great weakness. Edema occurs and albumin concentration in the blood is altered, as a sign of the self-digestion of muscle proteins.

From approximately 30 days of fasting, the state of malnutrition severely affects all body systems. After forty or fifty days the deterioration is noticeable due to physical wear, the person loses his mobility and suffers from unconsciousness. Finally, starvation death can occur from cardiorespiratory arrest or from lack of blood supply to the brain.

Describe the evolution of modern whales and dolphins using the fossil evidence
HACTEHA [7]
Whales are related back to a hairy, 4-legged land mammal that eventually led to the formation of flippers without phalanges, a blow hole that became more dorsal, and other defining features. All of this has been backed by fossil evidence, especially that found within a certain desert region (can’t remember the name) that has a vast amount of whale fossils from many different time periods
