Within a narrow range of temperatures, S. marcescens produces a red pigment called prodigiosin. Although the ultimate purpose of

the pigment is a mystery, it is known that at least 10 enzymes are required for its production. If one of these enzymes is rendered nonfunctional, how would you expect the appearance of the bacteria to change?

Answer:

Either the color will disappear or the brightness of the color will reduce as compared to the brightness in normal case.  

Explanation:

Non diffusible red pigment known as prodigiosin is a characteristics of S. Marcescens. Since, the red pigment is dependent on least 10 enzymes, it is clear that the pH and temperature range must be adequate for these enzymes to be functional. The optimum condition for pigment formation is 30 degree temperature and alkaline medium.

If any of the 10 enzymes become non-functional, the chances of attaining normal bright red color are not possible. Either the color will disappear or the brightness of the color will reduce as compared to the brightness in normal case.

NeX [460]

Answer:

I don't think there is a #6, so I'm gonna answer the "Mammals and plants don't belong in the same domain".. If this is the wrong one I can help with the one you actually need help with.

Explanation:

Myth: Mammals and plants don't belong in the same domain. 

Fact: Mammals, being a group of animals do not belong in the same domain as plants. Evidence: All living organisms are divided into three domains: Bacteria, Archaea and Eukarya. All of the organisms that possess a eukaryotic cell, plants, animals, protists, and fungi are in the Eukarya domain. Therefore, mammals and plants belong to the same domain, the Eukarya domain.

What kind of channels are located in the input region?
tamaranim1 [39]

Answer:

The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).

Explanation:

Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.

The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.

The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.

Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
