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.
Correct answer is ... Seeds have endosperm which provides nourishment for a new plant, but spores do not have any stored food supplies. :)
Explanation:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.b This phase was formerly called the resting phase.
ADP has two phosphate groups and ATP has three phosphate groups but they both have phosphate groups.
The answer is A.
The cuticle is a protective film that is non cellular covering the outer cell layer (epidermis) of green, aerial parts of plants. Cuticles protect plants against drying (desiccation), UV radiation, and various kinds of physical, chemical and (micro)biological agents.
The cuticle also provides some support. Actually the cuticle which protects the underlying tissues has basically the same function as our own skin.
In several groups of plants, cuticles are very resistant. Only few groups do not generally have highly resistant cuticles e.g. ferns and lycopods.
