The nicotine indirectly inhibit the CB1 or also known as the
Cannabinoid receptor type 1, which is the one responsible in obesity and
metabolic syndrome, thus, this would explain the weight gain associated with
people who quit smoke as if this is indirectly inhibited, it produces weight
gain.
Yes, they do:
In an F1 generation (first generation to be studied) all offspring will appear with dominant traits.
In an F2 generation (second generation to be studied) there is only a 25% chance of offpring having recessive traits (75% chance of dominant traits).

The glomerulus is supplied blood by the afferent arteriole, then the efferent arteriole takes away blood from the glomerulus.
The afferent arteriole has a larger diameter than the efferent arteriole.
The efferent arteriole, due to its smaller diameter creates some resistance to blood flow causing a blood back-up which creates a high pressure in the glomerular cavity. Therefore fluid and solute are forced out from the blood and into the glomerular capsule. Most of this filtrate is returned to the blood via peritubular capillary bed surrounding the nephron.
Answer:
Top predators at the highest trophic levels eat lower-level predators and herbivores
Explanation:
A trophic level is defined as one group of organisms in the ecosystem occupying the same level in the food chain, which is composed of different levels (primary, secondary and higher levels). Top predators at the higher levels maintain the trophic balance by eating other species that eat on primary producers/consumers, thereby favoring the homeostasis of the ecosystem.
