Answer:
Mitosis
Explanation:
Mitosis is a type of cell division in which a cell divides into two daughter cells each having the same number of chromosomes as the parent cell. It ensures that every body cell contains the same number of genes as the parent cell. The cell that have 78 chromosomes have undergone mitosis while the other cells that contain 39 chromosomes undergo meiosis.
Answer:
O With training, the puppies are likely to excel at agility competitions.
O Without training, the puppies are no more likely to succeed at agility competitions than any other dog.
Explanation:
This two options speaks the same thing and are the correct option.
The phenotype of an organism is a product of genotype and environment
P=G+E
The litters can inherit the trait of running, having a good vigour and ability to win agility competition but when the environment do not allow this trait to be expressed the trait can be masked i. e may not find expression.
The environment ensure that this litters are been taught the rudiment of agility competition to ensure they win if they are not been taught, they many not know they have the ability to win and will not be different from other dogs.
The training is what brings out the potential in them that can later be seen and expressed in the competition.
Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
Explanation:
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction.
