How did the Mafia gain the interest and scrutiny of the public?
mihalych1998 [28]

Mafia gain the interest and scrutiny of the public through their unique and fearful actions.

Mafia gain the interest and scrutiny of the public by threatening people in the society as well as killing some of them. The main aim of Mafia is to earn money so they perform many actions in order to gain money from the public such as extortion, kidnapping etc.

The person who gives money to Mafia is safe but that person who refuses to pay money to Mafia will gain the punishment of death so we can say that in this way Mafia gain the interest of the public.

A rooster with gray feathers is mated with a hen of the same phenotype. Among their offspring, 15 chicks are gray, 6 are black,
m_a_m_a [10]

Answer:

Alleles for feather colour exhibit incomplete dominance or co-dominance.

50% gray offspring + 50% black offspring

Explanation:

<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>

Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.

Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.

15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.

Bb   x   Bb = 1BB, 2Bb, and 1bb

Crossing the gray rooster (Bb) with a black hen (bb):

Bb   x   bb = Bb, Bb, bb, and bb

          = 2Bb (gray):2bb (black)

50% of the offspring will be gray while the remaining 50% will be black.

In the case of two EPSPs occurring at a single synapse, which of the following will produce a subthreshold effect and not genera
labwork [276]

Answer:

Both potentials occurring after the postsynaptic membrane potential returns to its resting value

Explanation:

This is simply because, a neuron returning to its resting state,will have the ligand gated Na+ channels closed.Therefore depolarization can not occur.More K+ gated channels will open, and more K+ leaks out of the axoplasm,returning the neuron to the resting state.

Hence if  the summation of the two EPSP returns to the resting level after crossing the synapse, they can not propagate,and generate action potential, because they will produce  a sub threshold effects,which  will not generate action potential.
