Option A. Bipolar disorder differs from schizophrenia in that schizophrenia typically involves hallucinations.
What is bipolar disorder?
- Bipolar disorder, previously known as manic depression, is a mood disorder characterized by periods of depression and periods of abnormally-elevated happiness that last from days to weeks each.
- If the elevated mood is severe or associated with psychosis, it is called mania; if it is less severe, it is called hypomania.
What is schizophrenia?
- A disorder that affects a person's ability to think, feel, and behave clearly.
- The exact cause of schizophrenia isn't known, but a combination of genetics, environment, and altered brain chemistry and structure may play a role.
What is hallucination?
- A perception of having seen, heard, touched, tasted, or smelled something that wasn't actually there.
- Hallucination can have causes that aren't due to underlying disease. Examples include drug intoxication.

A. Evolution is a scientific theory, and scientific theories have many hypothesis and experiments that support their findings.
Since no table is given, I will explain how genes are inherited. After Mendel’s discoveries were
accepted, scientists realized that traits passed to offspring were the result
of genes being passed from parents to offspring. This is an example of the law
of inheritance. The genes that are passed down from the parents are being
shared by the offspring. It can be shown if the trait is recessive or dominant
from the parents’ gene. <span>Chromosomes
are inherited from the parents. One chromosome from each of 23 pairs came from
each of the parents. The two chromosomes of a pair (except for the sex
chromosomes) contain the same genes, but the genes have small differences. The
X and Y Chromosomes determine the organism’s sex. One chromosome pair - the sex
chromosomes - is unique. Typically females have two X chromosomes and males
have an X and a Y. Mothers always pass an X chromosome on to their children.
Whether the father passes on his X chromosome (leading to a pair of X
chromosomes) or his Y chromosome (making a mixed set) determines your sex. </span>
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).
