Answer:
Option A, accumulate sulfur as intracellular granules.
Explanation:
Purple sulfur bacteria belong to the group of Proteobacteria. These probacterias are anaerobic in nature and yet are able to photosynthesise. They are usually found in water environments such as hot springs, stagnant water etc. They use sulphur (either in the form of sulfide, or thiosulfate) as an electron donor in their photosynthetic activity to oxidise sulfur thereby producing granules of elemental sulfur.
while filamentous sulfur oxidizers use nitrate instead of oxygen to oxidize sulfide thereby producing granules.
Hence, option A is correct.
<h2>Muscle contraction in cytoplasm </h2>
Explanation:
- Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
- ATP is basic to get ready myosin for official and to "revive" the myosin.
- When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
Answer:
<em><u>There are two important types of genetic mechanisms that can give rise to antibiotic resistance: mutation and acquisition of new genetic material. In the case of mutation, the rate at which resistance develops can be attributed to the rate at which bacteria mutate.</u></em>
Answer:
Answer is C. Brain-imaging technology.
Explanation:
The field interpersonal neurobiology is kind of new discovery, which was founded by Dan Siegel and Allan Schore, that is showing a framework on how to to understand the contribution of the brain to human, or better still, a framework showing to care for the mind.
And, brain-imaging technology, help to visualized the know-how map of the brain. This can also be referred to as the architecture structure of the brain.
