Answer:
During meiosis, an event known as chromosomal crossing over sometimes occurs as a part of recombination. In this process, a region of one chromosome is exchanged for a region of another chromosome, thereby producing unique chromosomal combinations that further divide into haploid daughter cells.
Chordates (phylum Chordata) are animals which are either vertebrates or one of several closely related invertebrates. They are united by having, for at least some period of their life cycle, a notochord, a HOLLOW DORSAL NERVE CORD
Answer:
The correct answer is option D, that is, 27.
Explanation:
27 three-nucleotide codons would be possible when polynucleotide phosphorylase is supplemented to a solution of GTP, ATP, and UTP. As there are three nucleotides available, that is, guanine, adenine, and uracil and each codon comprise three nucleotides, thus, there would be a probability of (3)^3 codons, that is, 27.

Explanation:
The correct answer is (b)The vestibular sense may be capable of sensory adaptation
Astronauts experience similar feelings of dizziness and disorientation upon arrival in space and upon their arrival back on Earth because the vestibular sense may be capable of changing adaptation. The dizziness and disorientation is due to the floating fluid in inner ear around zero gravity and it goes right away after some time when the astronauts reach the space. The adaptation is done by the brain to ignore the signals of the ear; the feeling this sensation for sometime the brain becomes adaptable and does not listens to the inner ear every time. This is a kind of sensory adaptation.
