In the study of ecology, the Winogradsky column is used for the effective cultivation of microbial growth in the water and soil of lake or stream to study the microorganisms ability to survive and produce different inorganic compounds at different environmental conditions.

The columns differs by the layers and composition such as carbon, sulphur and carbon + sulphur, exposed to light and non exposed to light so on.
All the columns are same in the way of subjecting under changes everyday.
The differences in the column can be seen by the changes in the color as the microbes produces their metabolic component (inorganic compound) which alters the pH of the environment gives different colors based the substrates present in the particular area. Thus based on the metabolic strategies, microbial population produced geochemical gradients inside the column.

Answer:

attenuation

Explanation:

"X-ray" is a type of radiation that is commonly used during diagnostic tests. It provides images within the person's body that are need for diagnosis. The images provided doesn't come in multi-colors but in "black-and-white." This largely depends on the penetration of the X-ray beam into the matter.

The deeper the penetration, the lower its intensity.

This means that the X-ray loses its energy as it travels deeper. The intensity then gets weaker.

If a person has not eaten for several hours and is experiencing hypoglycemia, which hormones are released to counteract the hypo

kykrilka [37]

Answer:

glucagon

epinephrine

cortisol

growth hormone

Explanation:

Hypoglycemia is a dizzying drop in blood sugar levels. When this occurs, symptoms such as dizziness, pallor and mental confusion arise. This problem is more common in patients with diabetes due to blood glucose fluctuation, but can also occur in completely healthy individuals who have spent several hours without eating.

During a hypoglycemic crisis, the patient should have a glass of orange juice, or non-diet soda, or half a glass of water sweetened with a sugar spoon, or suck on candy to replenish glucose levels. In addition, the body itself attempts to combat hypoglycemia by releasing the hormones glucagon, epinephrine, cortisol and growth hormone.
