[#566] Triploid tissue is
Correct Answer
(A) Endosperm in Maize/Wheat/Lily
Explanation
Solution: Triploid tissue is Endosperm in Maize/Wheat/Lily. The endosperm is a tissue produced inside the seeds of most flowering plants following double fertilization. It is triploid in most species, like wheat, maize and lily, etc. which may be auxin-driven. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This can make endosperm a source of nutrition in animal diets. For example, the wheat endosperm is ground into flour for bread.
[#567] The viruses which are usually helped or accompanied by smaller spherical particles of another serologically unrelated virus known as
Correct Answer
(A) Satellite virus
Explanation
Solution: The viruses are usually helped or accompanied by smaller spherical particles of another serologically unrelated virus known as the Satellite virus. A satellite is a subviral agent that depends on the coinfection of a host cell with a helper virus for its replication. They encode structural proteins to enclose their genetic material, which is therefore distinct from the structural proteins of their helper viruses. Satellites are completely dependent on a helper virus for replication. The symbiotic relationship between a satellite and a helper virus catalyzes the replication of a satellite genome.
[#568] Instantaneous source of energy is
Correct Answer
(A) Glucose
Explanation
Solution: An instantaneous source of energy is Glucose. Glucose is a simple sugar with the molecular formula C 6 H 12 O 6 . Glucose is the main sugar found in your blood. It comes from the food we eat, and is our body's main source of energy. our blood carries glucose to all of our body's cells to use for energy.
[#569] Genetic material of CaMV is
Correct Answer
(D) ds DNA
Explanation
Solution: The genetic material of CaMV is ds DNA. Cauliflower mosaic virus (CaMV) is a member of the genus Caulimovirus, one of the six genera in the family Caulimoviridae, which are pararetroviruses that infect plants. CaMV contains a circular double-stranded DNA molecule of about 8.0 kilobases, interrupted by nicks that result from the actions of RNAse H during reverse transcription. The CaMV genome consists of approximately 8,000 base pairs of circular, double-stranded DNA. The genome encodes seven genes (gene I to gene VII), also called P1 to P7 for encoded proteins 1-7.
[#570] SOP is better than MOP when the crops are
Correct Answer
(C) Senstivity to chloride
Explanation
Solution: SOP is better than MOP when the crops are Sensitivity to chloride. SOP is Sulphate of Potash and MOP is the Muirate of Potash means potassium chloride. Some of the crops are sensitive to chlorides then in that case SOP is better to use. SOP is not a naturally occurring mineral and usually must be produced through chemical methods. And because of the resource-intensive process used to create it, SOP is priced higher than MOP.
