Answer:
True
Explanation:
Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.
During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.
Hence, the given statement is true.

Answer:
The correct answer is c. rod-shaped cells with endospores
Explanation:
Most members of family Enterobacteriaceae can appear pink after gram staining due to porous membrane like<em> Zymophilus</em>, <em>Pectinatus </em>etc. Most of them form endospores which is a very tough outer covering formed by cells to resist the adverse condition. Many members of these family resides in intestine of animals and helps in food digestion.
These bacteria comes under phylum Firmicutes and mostly are rod shaped(bacillus). So when most of cells comes out purple the rod shaped cells with endospores indicates that gram stain contains the member of family Enterobacteriaceae.
Answer:
Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy.
Explanation:
Usually, this process uses oxygen, and is called aerobic respiration.
