Answer:
This question lacks options, the options are:
A) symbiosis
B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.
One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy in one of two ways.
Two pyruvate
Answer:
34
Explanation:
The electron transport chain of cellular respiration includes oxidation of NADH and FADH2. The electrons from these reducing powers are passed to the terminal electron acceptor via electron transport chain. During the transfer of electron via electron transport chain, the generated electrochemical gradient drives ATP synthesis.
The net yield of NADH from glycolysis and Kreb's cycle is 2 and 6 per glucose molecule respectively. In addition, decarboxylation of pyruvate also obtains 2 NADH per glucose. Kreb's cycle forms 2 FADH2 molecules during reduction reactions. In total, 10 NADH and 2 FADH2 are formed which then enter the electron transport chain and drive ATP synthesis.
One molecule of NADH generates the electrochemical gradient enough to drive the synthesis of 3 molecules of ATP while each FADH2 obtains 2 ATP molecules. Therefore, total 10 x 3 = 30 ATP molecules from oxidation of NADH and 2 x 2 = 4 ATP from oxidation of FADH2 are obtained.
Answer:
The claim by the researcher is supported because of the known functions of insulin and growth factors. Both hormones have a tendency to respond to the presence of glucose. The growth hormone initiates STAT5 signaling for producing the Igf-1 factor that is important for utilizing glucose. The insulin hormone is well known for utilizing glucose.
