Chromosomes are lined up in the middle of the cell during metaphase.
Answer:
The correct answer would be C) 75% large-toothed and 25% small-toothed.
It can be explained with the help of the law of dominance which states that the dominant allele expresses itself completely over the recessive allele in the heterozygous condition.
So, the genotype TT, as well as Tt, will result in the production of dominant trait or character in the offspring.
Thus, three (1 TT and 2 Tt) out of four offspring would have large teeth and only one offspring (tt) would have small teeth.
Hence, we can conclude that 75% of the offspring will have large teeth and only 25% will have small teeth.
Answer:
spinal cord
Explanation:
Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.
Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.
Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.
Hence, the correct option is spinal cord.
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.
