The difference in an area with high concentration and an area with low concentration is called concentration gradient.

<h3>What is concentration gradient?</h3>

Concentration gradient refers to the difference between the concentrations of two solutes in a solution.

A solution usually contains an area or region with higher concentration and an area with lower concentration.

The difference between these two areas of different concentrations is referred to as a concentration gradient.

Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes

oee [108]

Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt?

a. Photosynthesis

b. Lactic acid fermentation

c. Krebs cycle

d. Alcoholic fermentation

Answer:

b. Lactic acid fermentation

Explanation:

Lactic acid fermentation occurs when pyruvate formed by glycolysis is reduced into lactate under the anaerobic conditions. The NADH serves as an electron donor for the reduction of pyruvate into lactic acid. Lactic acid bacteria are the anaerobic bacteria that ferment the milk sugar lactose into lactic acid. This converts the milk into yogurt. Lactobacillus, Streptococcus salivarius, etc. are mostly responsible for the conversion of milk into yogurt.

Homework. Unanswered

Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.

All bacteria indicated in the question can be classified by the Gram staining test:

Actinomycetes are Gram-positive bacteria
The genus Arthrobacter includes Gram-positive bacteria
Escherichia coli (E. coli) is a Gram-negative bacterium
Staphylococcus spp. are Gram-positive bacteria
Bacillus spp are Gram-positive bacteria
Mycobacterium spp. are Gram-positive bacteria

Prokaryotes can be divided into two domains: Bacteria and Archaea.

Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.

In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).

Archaebacteria belong to the Archaea domain.
