Match the staining techniques with their purpose.
Dennis_Churaev [7]

A Negative stain such as India ink or Congo red-Look for the presence of a capsule.

This stain method is usually used to stain the area around the microorganism.

B The Gram stain-Divide bacteria into two groups based on cell wall structure (thick vs. thin).  

This is type of differential staining used to distinguish organisms based on their staining properties. Gram + and Gram- bacteria stain different because of different cell wall structure.

C The Ziehl-Neelsen Acid-fast stain- Identify bacteria with waxy cell walls such as: Mycobacterium tuberculosis (the cause of TB).  

This is also differential staining method which uses heat and phenol to derive dye into the cells with lipid-rich walls.

D Simple stain with a basic dye-Stain microbes a bright color to make it easier to see them in bright field microscopy.

One dye is used in simple staining in order to determinate the size, shape and arrangement of the cells.

E The Schaeffer-Fulton Endospore stain-Identify Bacillus or Clostridium species, such as the causative agents of anthrax, botulism, tetanus and gangrene.  

This is a special type of staining only used for the bacteria that can form endospores. Bacteria are first treated with heat and then with malachite green, which is very strong stain that can penetrate endospores.

Which ties to the Calvin cycle because it gives photosynthesis a pathway of light reactions and dark reactions.
vovangra [49]

Answer:

What is the link between the light reactions and the Calvin cycle during photosynthesis?

Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2

Onsidering that gluconeogenesis requires a net input of 4 atp equivalents compared to glycolysis, why would a cell utilize this
Pani-rosa [81]

The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.

  • The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
  • Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
  • For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.

Therefore, gluconeogenesis conserve more energy.
