the correct answer is D) The photovoltaic cells absorb light energy from the sun, then the energy is stored as chemical potential energy in the battery where it can be transferred to electrical energy.
Answer:
nervous system and autonomic system
Explanation:
because our nervous system is divided into two parts
Answer:
d. it diffuses into mitochondria to be broken down to generate ATP
Explanation:
When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.
The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.
Answer:
The correct answer is 327.78.
Explanation:
A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:
Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ
The given population of the country is 250 million
The number of individuals died due to a certain disease is 819450
Thus, the mortality rate per 100000 can be calculated as:
819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.
