B. Internal respiration occurs.
C. Ribs and diaphragm muscles contract.
D. Inspiration occurs.
Answer:
The correct answer is option A.
Explanation:
Breathing is the exchange of air through the involved passages in between the atmosphere and the lungs. Inspiration is a process where we take air into the lungs from the atmosphere also known as inhalation.
Expiration is releasing air out of the lungs to the atmosphere. In expiration, the diaphragm relaxation and elastic recoil of tissue decrease the thoracic volume of lungs. That results in an increase the intraalveolar pressure in the lungs.
Thus, the correct answer is option A.

The correct answer is A. Phenotypes
Explanation:
In genetics, the observable traits of an organism that includes behavior, physical traits, biochemical properties, etc. are known as phenotypes. These traits depend on both the genes of the organism (genotype) and the influence of the environment. Due to this, organisms of the same species with a similar genotype can display different phenotypes. This occurs in the case of Patrick and Michael as their observable traits or phenotype is different despite they are brothers. Thus, the observable characteristics are the phenotypes of an organism.
