In an ecosystem, organisms are dependent on each other for their survival. Small fish eat plankton. In the fish, chemical energy

from plankton is converted into and used by fishes to swim. These fish are then devoured by large fish. Bacteria break down the dead bodies of fish to release energy, which is then absorbed by other organisms in the ecosystem. This flow of energy is an example of the .

A food web or food chain

This flow of energy is an example of food web or food chain of the marine ecosystem.  

The energy flow in an ecosystem in the form of food from one organism to other is food chain. It comprises mainly of three types of organisms producers or autotrophs, consumers or heterotrophs and decomposers. The energy flow in food chain or food web is unidirectional from plants which are the primary producers to primary consumers or herbivores, then to secondary consumers or carnivores and finally to the decomposers. On its unidirectional flow the energy is lost in different form such as heat loss, decay, respiration etc. The energy passed from one level to another is not the same and gets lost in the process so when the energy is received from one tropic level to another it is always less than that received by the previous tropic level.

NAD and FAD work by loading and unloading _________ and _________ during energy transfers.
andrezito [222]

Answer:

Hydrogen and electrons

Explanation:

Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.  

For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.

A friend of yours claims to have identified a gene that causes a human disease! Your friend says that they have sequenced the DN
sattari [20]

Answer: Point mutation is easily reversible, thus non-lethal

Explanation:

Point mutation is caused by exchange of a single nucleotide for another. These change is called

1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)

2) Transversion (when a purine base substitute a pyrimidine base).

However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate

5. During cellular respiration, energy is stored in the form of _______.
Rudiy27
During the process of cellular respiration, energy is converted and broken down from a monosaccharide of glucose to form energy containing molecules, that facilitate the production of ATP. The energy in the form of glucose is utilized within the cells of the organism, and the organelle responsible for this process, of manufacturing ATP, a usable energy molecule within the cell would be the mitochondria.
