Answer:

A true understanding of the physiology of these bacteria and their roles in ecology, host health, and natural product production requires their cultivation in the laboratory. Recent advances in growing these species include coculture with other bacteria, recreating the environment in the laboratory, and combining these approaches with microcultivation technology to increase throughput and access rare species. These studies are unraveling the molecular mechanisms of unculturability and are identifying growth factors that promote the growth of previously unculturable organisms. This minireview summarizes the recent discoveries in this area and discusses the potential future of the field.

Asthma and COPD are both chronic lung diseases. COPD is mainly due to damage caused by smoking, while asthma is due to an inflammatory reaction. COPD is a progressive disease, while allergic reactions of asthma can be reversible.With asthma, the swelling is often triggered by something you're allergic to, like pollen or mold, or by physical activity. COPD is the name given to a group of lung diseases that include emphysema and chronic bronchitis. Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged.

Explanation:

Answer:

Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.

Explanation:

Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers. The food system remains within the local economy by being locally produced and eliminates the need for long-distance transportation. The opportunity to purchase locally grown food proves invaluable as the demand for it rises.

Answer:

Photosynthesis

Explanation:

Just like trees and other plants, grass converts energy from sunlight into sugar through the process of photosynthesis. This energy is used to convert water and carbon dioxide into glucose. Carbon dioxide is absorbed through the stomata in the leaf and water is mainly derived from uptake in the roots. Photosynthesis makes the grass green and healthy.

Answer:

Carbon dioxide is essential for internal respiration in a human body. Internal respiration is a process, by which oxygen is transported to body tissues and carbon dioxide is carried away from them. Carbon dioxide is a guardian of the pH of the blood, which is essential for survival.
