Answer:

There was no sulfur compound added to the medium, that could be used as an electron donor.

Explanation:

Bacteria that use light for energy requirements mean that they get their energy from photosynthesis and transferring energy through the molecules.

Bacteria play a major part in the reductive and oxidative cycle of the sulfur which is mediated by the help of photosynthetic bacteria, so the sulfur or sulfur compounds are major requirements for their growth in the habitat or the medium.

Thus, the correct answer would be- There was no sulfur compound added to the medium, that could be used as an electron donor.

Serjik [45]
<span>The mineral crystals in obsidian are too small to see without a microscope. This is because the rock cools so rapidly from magma that crystals barely have time to form. Obsidian is a normally happening volcanic glass framed as an extrusive molten shake. It is delivered when felsic magma expelled from a well of lava cools quickly with negligible precious stone development.</span>

Which organelles would create a basic protein that could be modified to move chromatids during metaphase?
bija089 [108]

The organelles would create a basic protein that could be modified to move chromatids during metaphase is the histine protien which is secreted from the RNA's.  

<u>Explanation:</u>

Histone protein is the protein that is associated with the chromosome. The chromatin fibres get condensed into chromosomes on these proteins.  

The chromatin fibre i.e. the DNA fibre gets to wrap itself around the histone octamer which is formed of two units of each of Histone H2A H2B H3 and H4. Then the H1 protein seals the turn and thus a chromosome is formed. These histone are produced in the S-phase of the cell cycle. This protein is transcribed into m-RNA's and then translated into protein.

What do fats, steroids, and waxes have in common? What do fats, steroids, and waxes have in common? (a) Moderate polarity. (b) L
hodyreva [135]

Answer:

Both (b) and (c)

Explanation:

Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.

Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
