A and C both seem like valid answers.
Foreshadowing means b. hinting at things that will occur later.
Answer:
observational learning
Explanation:
Mirror neurons are the neurons present in the frontal lobes and are responsible for observational learning. The action potential fired by these neurons is identical when a person observes an action and when the same action is being performed by the person itself.
For example, watching a child when he scores good in the examination, a teacher can sense the pleasure felt by him. This is because the teacher imitates the child in her own imagination and plays out the consequences and thereby understands the feeling of the child.
Answer:
8 possible combinations
Explanation:
In a diploid organism (2n), there are two sets of chromosomes in each cell. Each set of chromosome is contributed by each parent i.e one set of chromosome from the father and one set from the mother.
To determine the number of possible combinations in each gamete of a cell, we use the formula 2^n, where n = number of chromosomes in haploid gametes. In this case, the cell contains 3 pairs of chromosomes, meaning that each gamete will have 3 chromosomes. However, there will be 2³ = 8 possible combinations of chromosomes in each gametes.
Crossing over creates more variety by changing the linkage between genes. In a population that does not experience crossing over, the genes on the same chromosome will always be on the same chromosome and therefore inherited together.
In populations that do experience crossing over in diplonema during prophase I, the phenotypes will be more diverse because there is a greater chance for genes to be separated from one another and inherited separately. Crossing over does not always happen in the same location, so for populations in which this occurs, there is an exponentially greater number of inheritance combinations.
You should be able to answer your own questions with that information.
