KIA tubes and SIM tube in this exercise to determine whether or not your unknown produced H2S.

<h3>What gas is produced by Salmonella?</h3>

F0F1 ATP synthase activity is necessary for Salmonella typhimurium to produce hydrogen sulfide and fermentative gases.

<h3>H2S production by Salmonella enterica?</h3>

Infections with Salmonella enterica continue to have a serious impact on global public health. H2S-negative Salmonella have lately surfaced, despite the fact that the capacity of S. enterica to produce H2S is an essential phenotypic trait utilized to screen and identify Salmonella with selective media.

<h3>H2S is it produced by Shigella?</h3>

Shigella do not create H2S, hence colonies on Hektoen agar appear bluish-green rather than having the black center seen with Salmonella. Shigella are comparatively biochemically inactive and do not ferment lactose or xylose.

Which of the following expressions is not a function of mitosis?

madam [21]

The answer would be "production of gametes" or the first option. Is a mature haploid male or female germ cell which could collide with the opposite sex of the germ cell then for a thing called a zygote which is diploid cell that was formed because of the two gametes cells.

Hope this helps!

Describe how living things use anaerobic respiration to generate energy.

Mrac [35]

Anaerobic respiration is the process by which some organisms produce energy in the absence of oxygen. Instead of oxygen, organic and inorganic molecules are used as electron acceptors. One example of anaerobic respiration is fermentation.
In latic acid fermentation, one molecule of glucose undergoes glycolysis to produce two molecules of pyruvate. The two molecules of pyruvate then undergo fermentation to produce two molecules of lactate. The lactate will be transported to the liver. The lactate can be reconverted to pyruvate and utilized for energy. Latic acid fermentation occurs in the muscles.

List vertebral column bones in correct order from Cervical to Coccyx.

zimovet [89]

Answer:

Cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, coccyx.

Explanation:

Vertebral column or spine is made of a total of 26 vertebrae in adults. Starting from the upper part, it has 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, one sacrum, and one coccyx.

The coccyx is made of four fused coccygeal vertebrae. Likewise, the sacrum consists of five sacral vertebrae that are fused during development.

The genes dumpy (dp), clot (cl), and apterous (ap) are linked on chromosome II of Drosophila. In a series of two-point mapping c

Dmitrij [34]

Answer:

The order of genes is- dp-cl-ap

Explanation:

The genes a be mapped on chromosome on the basis of the recombination frequency as the recombination shows that is the genes are linked or not. In genetic mapping, 1 per cent recombination frequency is considered as 1 cM or map distance.

In the given question, the three gene distance are provided on the basis of which the gene can be mapped in the following manner:

1. Take the higher value of gene distance that is 42 m.u and plot them on the line,

2. now place second-highest value on the line that is 39 m.u.

3. The gene will be arranged in the order of dp-cl-ap.

4. dp--³---cl-----------³⁹---------------------ap.

Thus, dp-cl-ap is correct.
