It is the identity of the genes of your chromosomes that is your genetics that may not be physical, as compared to a phenotype which is a physical trait.
Answer: D. Epinephrine
Explanation:
During perceived danger the fight-or-flight response includes faster heart beat, quickened breath, tense muscles and thought speed up. This co-ordinated set if physiological changes is triggered by two hormones of the adrenal gland, epinephrine and norepinephrine.
The major activities of these hormones is to increase the amount of chemical energy available for immediate use, increase the heart rate and stroke volume and dilate the bronchioles in the lungs, action the raise the rate of oxygen delivery to the cell.
Answer is epinephrine
Answer:
The elemental is required in very small amount. (Ans. A)
Explanation:
Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).
Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.
Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.
So, the adjective trace means that the elemental is required in a very small amount.
Oxidative phosphorylation requires a proton gradient.
- Cells use enzymes to oxidize foods in the metabolic pathway known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate.
- This happens inside mitochondria in eukaryotes. The majority of the energy required for biosynthesis, maintaining a healthy ion balance, and mechanical effort is provided by oxidative phosphorylation, which is the principal source of ATP in higher animals.
- A succession of proteins and electron carriers in the mitochondrial membrane, as well as the electron transport chain, are all involved in the process of oxidative phosphorylation.

A decomposer is an organism usually a bacteria or fungus that decomposes organic material.
Decomposers are considerd the last tropic level because they feed on everything.
