[#306] Dockage means
Correct Answer
(B) Impurity percentage of seed lot
Explanation
Solution: Dockage means Impurity percentage of the seed lot. Freshly harvested grain contains a small proportion of impurities, which is called dockage. 5.0% or less of the gross weight, assess as dockage. Determine the percentage of dockage by combining and weighing all of the material which remained on top of the top sieve and which passed through the bottom sieve. The percentage is calculated by dividing the weight of the dockage by the total sample weight.
[#307] An individual having both male and female reproductive organs is known as
Correct Answer
(B) Hermaphrodite
Explanation
Solution: An individual having both male and female reproductive organs is known as Hermaphrodite. hermaphrodite is an organism that has both kinds of reproductive organs and can produce both gametes associated with the male and female sexes. It is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. A hermaphrodite flower that has both staminate (male, pollen-producing) and carpellate (female, ovule-producing) parts.
[#308] Assumptions of Hardy-Weinberg law are
Correct Answer
(D) All of the above
Explanation
Solution: Assumptions of Hardy-Weinberg law are all the above that are Organisms are diploid, Mating is random and Population size is infinite. Hardy-Weinberg Equilibrium (HWE) is a null model of the relationship between allele and genotype frequencies, both within and between generations, under assumptions of no mutation, no migration, no selection, random mating and infinite population size.
[#309] In flowering plants who discovered the fertilization?
Correct Answer
(B) Strasburger
Explanation
Solution: In flowering plants, Strasburger discovered fertilization. Eduard Adolf Strasburger was a Polish-German professor and one of the most famous botanists of the 19 th century. He was the first to provide an accurate description of the embryonic sac in flowering plants, along with demonstrating double-fertilization in angiosperms. The process of fertilization in flowering plants was first discovered by Strassburger in 1884. He showed that during fertilization in flowering plants the nucleus is the primary structure concerned with heredity.
[#310] Oxysomes occurs in
Correct Answer
(D) Mitochondria
Explanation
Solution: Oxysomes occur in Mitochondria. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. Oxysomes are small round bodies found in the folds of the cristae in the inner mitochondrial membrane and are involved in ATP synthesis. The folds are studded with small round bodies known as F 1 particles or oxysomes.
