why was it impossible to know about bacteria 5,000
years ago
Answer:
Im assuming because microscopes hadnt been invented. Also the idea of communicable diseases wasnt around so people assumed it was things like god that caused illness
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.

What is the difference between emphysema and asthma?
Emphysema is an inflammation of the lungs, while asthma is a bacterial infection of the lungs.
Emphysema is the gradual destruction of the alveoli, while asthma is a sensitivity to irritants that causes the airway to constrict.
Emphysema is a sensitivity to irritants that causes the airway to constrict, while asthma is the gradual destruction of the alveoli.
Emphysema is a bacterial infection of the lungs, while asthma is an inflammation of the lungs.
Answer:
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.

How many combinations of A, C, G, and U exist? Include an equation
Answer:
64
Explanation:
4 ^ 3 because your first nucleotide can be any of the 4, same with your second, and same with the last nucleotide. 4^3 tells you there are 3 different positions that 4 different bases can be placed.
Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

Which process does the grass used to make the food this horse needs?
A.) Photosynthesis
B.) Respiration
C.) Eating
D.) Digestion
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.

Why is farming good for the society? (Economic growth related) please give me scientific questions, I will mark you as brainly. Thank you
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.
