Snakes would most likely affect food production
Answer:
Moose may have evolved to become larger because they could better protect themselves from predators. What other factors might have caused this? Answers vary, but may include sexual selection, warmth, parasites and disease, etc.
Explanation:
Answer:
Natural selection
Explanation:
Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.
This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
Answer:
c.Alejandro’s nurturing parents. Alejandro’s genotype includes exceptional musical ability, but it’s his parents’ support of this ability that encouraged those genes to be expressed.
Explanation:
this is an examole of the influence of environment on gene expression
His nurturing parent's support aided his skill developments for professionalism. Generally parents have great influence on the children social skill developments through thorough supervision and monitoring of their general activities.
In addition, they are the social vessels for their child's social interactions, and therefore determiners of the experience to pass though in their immediate environments. Conclusively parents influences determine a child future.
In Alejandro case, the profession of both parents, the monitoring of his activities with musical instruments, and his regular practice(for the development of neural pathways) showed influence of environment on the expression of genotype, which aided his professionalism.
If he was not born to family of guitarist,with no access to a guitar he may not be a professional despite his musical genotype. thus interaction between gene and parental nurturing (environments) favoured this.
