one of the following that is not a possible cause for the growth is B
An increase in the population of prey it feeds on.
Answer: A.Caffeine
Explanation:
Caffeine works by blocking adenosine, a neurotransmitter that promotes sleep. This makes us feel more awake and alert. It's the most commonly used psychoactive substance and is found in many everyday items like coffee and medicines.
The actual mechanism of A) Caffeine is to block chemicals that inhibit or slow nerve activity in the brain. Caffeine functions as an adenosine antagonist, meaning it inhibits the adenosine receptors. Adenosine is a neurotransmitter that promotes sleep, so caffeine's effect reduces sleepiness and enhances alertness.
This mechanism allows caffeine to indirectly increase adrenergic activity (energy release), promoting a more energetic state. While caffeine is often associated with increased alertness and arousal, it's important to remember that it's acting primarily by blocking the inhibiting effect of certain chemicals on the brain nerve activity.
It's noteworthy that caffeine, as the world's most widely consumed psychoactive drug, is unregulated, found in everyday items like beverages and medicines, and generally not harmful in moderation.

Answer:
c
Explanation:
genotypic inheritance
Answer/Explanation:
Let's say the allele for short hair is S and the allele for long hair is s. Since long hair is recessive, an individual would need to have two copies of that allele to show the genotype (h0m0zygous - ss). That means they must inherit one from each parent.
A guinea pig with short hair could be h0m0zygous (SS) or heterozygous (Ss)
Since a short haired male and a short haired female produced some long haired offspring, they must each have a copy of the long haired allele (s). Otherwise there is no way their offspring could inherit two copies of the s allele. The offspring must have got one s allele from each parent.
Therefore, the parents must both be heter0zygous (Ss)
