Heterotrophic Nutrition, Excretion, and Respiration review

Which substances are Metabolic Waste products Carbon dioxide, water, urea Glucose, water, oxygen Carbon dioxide, water, sugar Oxygen, water, protein

The adaptations that allow organisms to remove cellular wastes effectively vary according to The color of the external surface Metabolic activities and the environment it inhabits Number of offspring Size of the organism and reproduction

freshwater protozoans excrete ammonia and mineral salts by means of Small vacuoles released through the membrane Small tubes leading from the cyroplasm to openings in the cell membrane Contraction of food vacuoles Diffusion through the cell membrane

Which organism has excretory organs most similar to the nephrons in the kidneys amoeba hydra earthworm grasshopper

Which organism is paired correctly with the excretory adaptation used for removal of nitrogenous wastes Grasshopper-nephron Earthworm- nephridia Human – malphigian tubules Hydra - kidney

Grasshoppers conserve water by excreting nitrogenous wastes in the form of ammonia urea Uric acid Carbon dioxide

Which human excretory organ breaks down red blood cells? lung kidney skin liver

Which structures filter and moisten air as it passes through the euman respiratory system? Alveoli and cartilage rings Diaphragm and bronchioles Epiglottis and bronchi Cilia and mucous membranes

Which structures in the nasal cavity remove some bacteria and dust from outside air before it enters the lungs? Ciliated mucous membranes Thin, moist alveoli Lymph nodes Rings of cartilage

Humans breath more rapidly during exercise because the blood contains More oxygen Decreased red blood cells Increased levels of CO2 Decreased bile

In humans most gas exchange occurs between the Excretory tubules and body cells Arteries and blood cells Alveoli and capillaries Skin and air

Smoking may damage the respiratory system because? Interfere with ciliary action of the trachea Trigger the release of bile by the liver Block the regulation of breathing Lower blood pressure in the alveoli

A disorder of the digestive system that can cause a problem with the emulsification of fats gallstones anorexia Constipation diarrhea

Which structure creates a substance that aids in the mechanical breakdown of fats? Gall bladder Pancreas Liver rectum

This structure is found in the Stomach Small intestine Esophagus Large intestine

Pepsin and Trypsin are classified as Sugars Carbohydrates Lipids proteins

Pepsin operates best at a pH of 8. It is most likely found in the Stomach Esophagus Small intestine Large intestine
