I think Acetic acid will be produced if wine is aerated and inoculated with bacteria of the genera acetobacter and gluconobacter. Acetobacter is a genus of acetic acid bacteria. This bacteria is used for the mass production of Acetic Acid, the main component in vinegar. Gluconobacter is also a genus of the acetic acid bacteria family.
Answer: The correct answer is option a.
Explanation:
Prezygotic isolation is a mechanism by which mating and fertilization is prevented. Thus, it prevents the formation of a zygote.
It can be achieved by various reasons such as temporal differences (difference in mating seasons), habitat isolation, behavioural differences (different mating rituals such as different dance patterns, voice calls, et cetera), mechanical isolation, et cetera.
Thus, different breeding calls prevent the species to interbreed with each which ultimately prevent the formation of zygote formation.
Hence, it is a type of prezygotic isolation.
Answer:
A. Miosis
B. DNA molecule
C. Body cells
D. phenotype
E. Recessive traits
F. genotype
G. Punnet square
H. nondisjunction
I. mitosis
J. sex cells
Explanation:
In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.
