The <span>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.</span>

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.

Radda [10]
• Genes can contain more than one polyadenylation site, which alters the 3' of the mRNA transcript and the inclusion/exclusion of exons.
• mRNA transcripts from the same gene can be differentially spliced to include/exclude exons.

In the electron transport system
antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

However, had it been a real sound, the sound's pitch would have been increased by the Doppler Effect, since the Falcon was movin
kow [346]

Answer:

Towards the southern of the sound

Explanation:

As the motion of the source of sound is moving,the percieved sound frequency varies .this is known as Doppler effect.the sound waves emited by the sources tends to bunch up in front of the source and spread out behind the source.

Since the falcon is moving towards the sound,the frequency increases and so does the pitch of the sound

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.
