Answer:
The brain and the spinal cord are wrapped in three protective layers of tissue called the meninges. The cerebral spinal fluid goes between these layers to provide more cushion and protection. It nourishes and protects the nerve tissues of the brain and spinal cord. It also acts as a shock absorber, considering humans move a lot and fall.
Answer:
The correct answer is option C. gibberellin.
Explanation:
Gibberellin is a type of fungal and plant growth hormone. Gibberellin is one of five main groups of plant hormones.
Gibberellin has different functions and roles in plant growth and regulation such as stem elongation, stem germination, fruit ripening, and flowering.
The gibberellin acid class of hormones has been commonly used in the control of flowering in several species by the florist,
Thus, the correct answer is option C.
Answer:
D. 1/64
Explanation:
The desired genotype for the progeny = aabbcc (homozygous recessive for all the three loci). The probability of getting a progeny with a homozygous recessive genotype can be calculated during the product rule.
The parent genotypes= AaBbCc x AaBbCc
Aa x Aa = 1/4 AA: 1/2 Aa: 1/4 aa
Bb x Bb = 1/4 BB: 1/2 Bb: 1/4 bb
Cc x Cc = 1/4 CC: 1/2 Cc: 1/4 cc
Therefore, the probability of getting a progeny which is homozygous recessive for all the three traits (aabbcc)= 1/4 aa x 1/4 bb x 1/4 cc = 1/64
