How do the Earth and Moon compare in terms of gravitational force?
Law Incorporation [45]

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.

Option A

<u>Explanation:</u>

According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.

In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.

F=\frac{GM}{R^{2} }

So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.

Dimas [21]

Answer:

The answers are c)are the most reinforcing, generate the greatest immediate sensual appeal, and produce the most powerful psychological dependence.

Explanation:

Like all psychoactive substances, amphetamines affect the central nervous system and have stimulating effects (empathy, sensuality, confusion, etc.), producing an alert state along with various reactions in perception. Some individuals also report optical and auditory illusions. On many occasions this is also favored by the existence of intense visual and auditory stimuli, as happens for example at parties. However, most of these desired effects have tolerance with repeated doses of the same substances and even cross tolerance with doses of other substances. With the appearance of this tolerance other effects appear such as aggressiveness, anxiety symptoms, panic attacks, etc.

Among the medical complications related to the use of these substances, acute neurological complications, seizures and cerebrovascular diseases stand out.

Complex Chemical media is a media whose component are not known. It includes both animals,yeast, plant source whose component are not known this Mixture makes it complex.

Example of complex media is Human Endothelial-SFM (Life Technologies), Endothelial Basal Media, EndoGRO-LS Complete

Example of chemically defined media enhancing or inhibitory effects of GSLs and sphingolipids on tyrosine kinases associated with growth factor receptors.

USPshnik [31]
I would say that the fishes exhibited the greatest diversity (though the brachiopods also had considerable diversity) and mostly were of the ostracoderms (with a platey or shell-like skin and no jawbone) which exhibited many varieties and also the placoderm which had gills, a jawbone and fins so was developing characteristics of modern fish.
