Answer/Explanation:
DNA replication doubles each chromosome, meaning the cell can pass on DNA to daughter cells - the duplicated DNA is divided equally between the two new cells formed from the parent.
The laws of inheritance are:
1) The Law of Dominance: An organism with alternate forms of a gene, called alleles, will always display the form that is dominant, masking the recessive trait.
2) The Law of Segregation: In a diploid genome, like most eukaryotes, each trait is defined by a pair of genes (alleles). Each allele is randomly passed on to the gametes so that each gamete only contains one allele. The offspring inherits one allele from each parent during the process of fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted independently from one another That is, the inheritance of one trait does not depend on the inheritance of another trait. so that the inheritance of one trait is not dependent on the inheritance of another.
Explanation:
HIV virus is an RNA virus
This chocolate is most likely milk chocolate made in the United States.
Fruit flies produce offspring relatively fast and have specific traits, such as eye color and body color/shape. They are easy to observe and their traits are easily traced throughout the next generations.
Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
