Answer:
Mendel's law of dominance
Explanation:
A pea plant homozygous for purple flowers could have the genotype PP. A pea plant homozygous for white flowers could then have the genotype pp.
This means that all the offpsring have the genotype Pp, see the attached punnet square.
Because the P allele is dominant to the p allele, the plants have purple flowers. This is in agreement with Mendel's law of dominance. This states that for a dominant trait (following a cross of two different homozygous genotypes), hybrid offspring of the next generation will always express the dominant allele.
Answer:
"50%, so you are correct, legislation can lead to significant positive health outcomes."
Explanation:
Health and safety legislation. Safe exercise is very significant to the raise of self-respect in care. There are a few governmental procedures and rules to care health and safety at work. These are planned to defend people in work, those by means of facilities and the broader public. Legislation is one of the most significant tools of administration in organizing society and defending citizens. It controls between others the privileges and tasks of persons and establishments to whom the legislation applies
Answer:
Addiction.
Explanation:
A person with an addiction uses a substance, or engages in a behavior, for which the rewarding effects provide a compelling incentive to repeat the activity, despite detrimental consequences. Addiction may involve the use of substances such as alcohol, inhalants, opioids, cocaine, and nicotine, or behaviors such as gambling.
There is evidence that addictive behaviors share key neurobiological features: They intensely involve brain pathways of reward and reinforcement, which involve the neurotransmitter dopamine. And, in keeping with other highly motivated states, they lead to the pruning of synapses in the prefrontal cortex, home of the brain's highest functions, so that attention is highly focused on cues related to the target substance or activity. It is important to know that such brain changes are reversible after the substance use or behavior is discontinued
