Q: Pulmonary ventilation in mammals occurs via what? Read this paragraph and choose the correct option from the provided answers: Mammalian Systems In mammals, pulmonary ventilation occurs via inhalation (breathing). During inhalation, air enters the body through the nasal cavity located just inside the nose (Figure 39.7). As air passes through the nasal cavity, the air is warmed to body temperature and humidified. The respiratory tract is coated with mucus to seal the tissues from direct contact with air. Mucus is high in water. As air crosses these surfaces of the mucous membranes, it picks up water. These processes help equilibrate the air to the body conditions, reducing any damage that cold, dry air can cause. Particulate matter that is floating in the air is removed in the nasal passages via mucus and cilia. The processes of warming, humidifying, and removing particles are important protective mechanisms that prevent damage to the trachea and lungs. Thus, inhalation serves several purposes in addition to bringing oxygen into the respiratory system. Choices: - inflammation - osmosis - ingestion - inhalation A:
inhalation

Q: Where does the process of assembling amino acids into a protein take place? Read this paragraph and choose the correct option from the provided answers: The process of assembling amino acids into a protein takes place in the ribosome. This structure consists of two subunits, each of which is composed of both proteins and ribosomal RNA (rRNA). The two subunits clamp together on the mRNA and catalyze the formation of the amide linkages in the growing protein. When protein synthesis is complete, the two subunits dissociate and release the completed protein chain. Choices: - in the nucleus - in chromosomes - in the chitin - in the ribosome A:
in the ribosome

Q: Q: What is absorbed from food waste in the large intestine before it passes out of the body as feces? Read this paragraph and choose the correct option from the provided answers: Excess water is absorbed from food waste in the large intestine before it passes out of the body through the anus as feces. Trillions of helpful bacteria also live in the large intestine. They carry out important roles, such as making vitamins. Choices: - distilled water - dependent water - inactive water - excess water A:
A: excess water

Question: Q: Is the most basic what is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions? Read this paragraph and choose the correct option from the provided answers: Section Summary 1.1 Physics: An Introduction Science seeks to discover and describe the underlying order and simplicity in nature. Physics is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions. Scientific laws and theories express the general truths of nature and the body of knowledge they encompass. These laws of nature are rules that all natural processes appear to follow. Choices: - experiments - biology - genetics - physics A:
Answer: physics

Q: What body part does encephalitis attack? Read this paragraph and choose the correct option from the provided answers: Encephalitis is a brain infection ( Figure below ). If you have encephalitis, you are likely to have a fever and headache or feel drowsy and confused. The disease is most often caused by viruses. The immune system tries to fight off a brain infection, just as it tries to fight off other infections. But sometimes this can do more harm than good. The immune system's response may cause swelling in the brain. With no room to expand, the brain pushes against the skull. This may injure the brain and even cause death. Medicines can help fight some viral infections of the brain, but not all infections. Choices: - lungs - liver - heart - brain A:
**Answer**
brain
