Answer:

electrical synapse

Explanation:

An electrical synapse provides channel of proteins referred to as gap though which two neurons are connected. This connection allows the electrical signal to travel from cell to the other. Electrical synapses are commonly found in the brain and nervous system of an organism

In this synapse, there is a passive flow of ions from one neuron to the other through the gap junction pores. The neuron from which the current flows is called as presynaptic element and is also referred to as upstream neuron while the neuron which receives the current is called as postsynaptic or downstream neuron.

Synapses in which gap junctions allow ions to diffuse quickly from cell to cell are called ELECTRICAL synapses. An electrical synapse is a mechanical and electrically conductive link between two neighboring neurons that is formed at a narrow gap between the pre-synaptic and post-synaptic neurons known as a gap junction.

In the classic Meselson and Stahl experiment, E. coli are first grown in 15N-enriched media (0th generation) and, subsequently,

Answer:

The correct answer is - option e.)

Explanation:

The experiment that was performed by Meselson and Stahl was created to prove that DNA replication is a semiconservative process.

When Bacteria grow on 15N media they incorporate the isotype of nitrogen and after few generations, the culture moved to 14N media where it incorporates as they replicate in semi-conservative mode and one DNA strand comes from the Parent DNA.

The right option for question one is Option (e) Run as one band, at a position expected for DNA containing a 14N:15N ratio equal to 1.

How long after conception can you get a positive pregnancy test

sasho [114]

Answer: Although many tests indicate you can test as soon as five days before your next period, the most accurate results will be obtained after you have missed your period and the earliest a test can provide an accurate reading is 14 days after conception. Tests differ in sensitivity in detecting HCG in the urine.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over spher

dangina [55]

Answer:

Genotypic ratio = 16 WwDd: 0

Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit

Explanation:

This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).

According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:

WWDD - WD, WD, WD, WD

wwdd - wd, wd, wd, wd

Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.

The genotypic ratio is 4 WwDd: 0

The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.
