Answer:
to prevent the virus to have a big effect on the body of humans so the cells can fight against it
Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
<span>Sexual fertilization takes place
when a sperm from the male fuses into the egg cell of the female. <span>Human cells contain 23 chromosomes and has a total of 46
pairs of chromosomes. A male has a total of 46 pairs chromosomes and gives 23 chromosomes
while a female has a total of 46 pairs of chromosomes and gives 23 chromosomes
to the offspring. These pairing are responsible to the trait of the offspring. The
formation of both male and female gametes creates a zygote. They will start to
form at the fallopian tube, down to the oviduct and into the uterus as it
continues to divide. </span></span>
A drosophila mutant that has legs instead of antennae in its head is caused by a mutation in the phenotype is most likely found in the homeotic genes. The homeotic genes are the one responsible in regulating or formation of the structures in animals. This is likely where the mutation is found, causing the drosophila have legs on its head.
