Correct Answer: FALSE
Explanation:
The right ventricle transports deoxygenated blood to the lungs, where the oxygenation takes place.
Hence, the given statement is FALSE.
Correct Answer: have some embryonic development outside the uterus
Correct Answer: nucleoid
Correct Answer: DNA replicates before the division
Correct Answer: Allows for expansion or contraction of the trachea
Explanation:
Allows for expansion or contraction of the trachea. Hence, so large masses of food can pass through the esophagus during swallowing.
Correct Answer: Polygenic traits
Correct Answer: Nucleus
Correct Answer: Schizophrenia
Explanation:
Antipsychotic drugs have proved helpful in the treatment of schizophrenia and other psychotic disorders, inhibits dopamine, reduces delusions, hallucinations, thought disorganization.
Correct Answer: Golgi apparatus
Correct Answer: Replication occurs as each base is paired with another exactly like it.
