Question

The attractive color of apples may be induced by reducing the supply of
A. Calcium
B. Nitrogen
C. Potassium
D. Boron

Answer 1

The element that induces colour in apples is a fundamental supplement for plant development, improvement, and generation. In spite of being one of the most plentiful components on earth, its inadequacy is presumably the most widely recognized wholesome issue influencing plants around the world.

Complete answer:
- Nitrogen is so fundamental since it is a significant part of chlorophyll, the compound by which plants use daylight energy to create sugars from water and carbon dioxide (i.e., photosynthesis).
- It is likewise a significant part of amino acids, the structure squares of proteins.
- Without proteins, plants wilt and bite the dust. A few proteins go about as auxiliary units in plant cells while others go about as compounds, making conceivable a considerable lot of the biochemical responses on which life is based.
- Nitrogen is a part of energy-move mixes, for example, ATP (adenosine triphosphate). ATP permits cells to moderate and utilize the energy delivered indigestion.
- At last, nitrogen is a critical part of nucleic acids, for example, DNA, the hereditary material that permits cells (and at the end entire plants) to develop and repeat.
- Without nitrogen, there would be no life as we probably are aware of it.
- Nitrogen being a constituent of amino acids, is significant for the development of plants.
- Be that as it may, for an ideal yield of organic products in natural product trees is reliant on harmony among vegetative and contraceptive development, since natural products are the result of sexual proliferation in plants.
- Red tone creates an apple because of the gathering of anthocyanin shade and is exceptionally reliant upon nitrogen level and light entrance inside the covering.
- Clearly, nitrogen ought to be applied right on time during vegetative development yet accordingly nitrogen gracefully can be decreased for the improvement of splendid red tone in apple skin.

Hence, the correct answer is option (C).

Note: At some random time, 95 to 99 percent of the conceivably accessible nitrogen in the dirt is in natural structures, either in plant and creature buildups, in the moderately steady soil natural issue, or in living soil life forms, for the most part, organisms, for example, microorganisms.
