Answer: 20 mg

Explanation:

Lethal overdose can be defined as the dose which is an indication of the lethal toxicity of the given substance. It can be defined as the dose of substance above which it is considered lethal.

The lethal dose for heroin is 20 mg above which it can be deadly for a number of people.

There are chances that some people might not die because the effect varies from person to person.

Answer:

I'm thinking maybe B, illustrates the principle of natural selection.

Explanation:

This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.

Suppose that Rose has myotonic dystrophy and shows traits such as uncontrolled muscle activity. Rose\'s mother, Becky, is dystro
Bogdan [553]

The six pedigree symbols with the corresponding names of the individuals in Rose's family will be like  2nd - Rose; 7th - Becky; 4th - Dave; 8th - Mike; 10th - Pat and 13th - Erik.

The second will be Rose because Becky's father, who is Rose's husband, is healthy and Jess, Becky's mother, has myotonic dystrophy. The seventh person is Becky, who has myotonic dystrophy and is married to Mike, who is healthy. Dave, who has myotonic dystrophy, is the fourth.

Mike, who is normal and married to Becky who has the condition or is impacted, comes in at number eight. Pat (unaffected), the daughter of Dave and Mary, is ranked tenth. Erik (affected), the son of Becky and Mike, is the 13th person on the list.

Myotonic dystrophy is an autosomal dominant condition that is passed vertically from parents to offspring. This illness affects both men and women equally and does not pass down through generations.

Which current is produced inresponse to a hyperpolarizing stimulus in a giant axon of a squid?
bekas [8.4K]

The giant axon of a squid, shows that hyperpolarizing stimulus is followed by transient inward capacitive current and lasting outward capacitive current.

Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.

Hyperpolarization can be caused, for instance, by opening channels that allow positive ions to move out of the cell (or negative ions to move in).

The hyperpolarization-activated current is an inward current activated by hyperpolarization from the resting potential and is an important modulator of action potential firing frequency in many excitable cells.
