It's 1 electron, sodium has an extra valence electron to transfer to chlorine.
Answer:
Incubation period
Explanation:
The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient). It is during this time the pathogen begins multiplying in the host
<span>The
answer is D. So as to take the shortest time to react to stimuli, most sensory neurons
are looped through the spinal cord to motor neurons. Following a reflex action,
the signal is later passed to the brain, from the spinal cord, for the signal
to be analyzed. A reflex arc is divided into
somatic and autonomic reflex arcs. The former is connected to outer muscles
while the later to inner organs. </span>
<span>A. The Archaea have cell membranes made of ether-linked hydrocarbons which branch, while Bacterial membranes are made of ester-linked fatty acids.</span>
Meiosis is a cellular division that produces four haploid daughter cells from a parent cell. It is observed in gametes/sex cells. The process of meiosis undergoes two consecutive divisions. Each division has five phases: prophase, metaphase, anaphase, telophase, and cytokinesis.
In Meiosis I, the chromosomes of the parent cells are multiplied. Each chromatid of the chromosomes exchanges genetic information, or <em>recombination</em>. The number of chromosomes at the end of Meiosis I is haploid but the chromatids of the chromosomes are still attached to each other. Due to recombination, the sister chromatids may not be identical to each other.
In Meiosis II, the chromosomes are separated and produce four daughter cells. It is shorter compared to Meiosis I because it no longer replicates the DNA or exchanges genetic information, and just separates the prepared chromatids from Meiosis I. It is similar to mitosis since it begins with a haploid cell and ends with a haploid cell.
