How quickly do sunspots form? How long do they last? What is the length of the average sunspot cycle? (site 1)

The sunspots form when the sun's magnetic field protrudes through its surface. The sun's magnetic field is composed of tubes that affect the sun’s surface temperature at the point of protrusion. Hope this helps. Have a nice day.

Answer:

There are different form or level of physical effects due to the sun rays or any electromagnetic radiations that are exposed to the human integumentary system or mainly the human skin. As, they are formed to the degeneration of some of cells or the pigments present inside the human skin. As, they have the optimum level of requirements to grow and develop themselves, for that reasons the sunspots are created on the region or part of the human body to which the electromagnetic radiations are exposed.
As, the sunspots may last for a much longer duration, which might precede in the formation of the sunspots which would last for a tenure of about seven years.
While, the length of the average sunspot all depends upon the body mechanism of the target individuals.

creativ13 [48]

Answer: True

Explanation: Like all living things, prokaryotes need energy and carbon. They get energy from inorganic chemical compounds.

Chemoautotrophs are organism that utilizes inorganic molecules to supply energy for the organism, and use carbon dioxide as a carbon source. Chemoautotrophs are mostly prokaryotes that break down hydrogen sulfide and ammonia.

Most Eukaryotes cannot utilize these inorganic molecules as energy source.

Studentka2010 [4]

Answer:

Becomes completely enclosed by the region of the cell membrane into which the spikes and matrix protein are embedded

Explanation:

The viral capsid is a protein shell that sorrounds a virus, it serves as a criterion for the classification of viruses and it encloses the genetic material of the virus and it has glycoproteins (spikes and matrix) embedded in it.

I hope you find this information sueful and interesting! Good luck!

aivan3 [116]

Answer:

DNA ligase

Explanation:

DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;

initiation
elongation
termination

Initiation involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme

Elongation involves binding of RNA primer to the DNA strands and addition of bases to the primer to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).

Termination involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.

The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.

Hence, the answer is DNA ligase.
