Why have scientist devised a system of comparative weights for atoms rather than using actual weights

Biology
1 answer:
tatuchka [14]2 years ago
5 0

Answer:

Because of multiple reasons:

Explanation:

  1. Atoms are way too small to weigh.
  2. They couldn't use weight, they would have to use mass.
  3. Some atoms are free-floating, because they are the air.
  4. If they even made a scale that measured each atom, it would also catch the air atoms as well, unless they had a vacuum chamber, but even then, no one can make a perfect vacuum, space is not even a perfect vacuum...

Hope this helps.

Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase
Serggg [28]

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.

Zarrin [17]

The answer is B)<span> </span>temporal isolation.

<span>
<span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>

The muscles of a recently deceased human can remain in a contracted state, termed rigor mortis, for several hours, due to the la
forsale [732]

Option A is correct. These ions then have interaction with actin and myosin filaments to purpose muscle contraction. The muscle groups stay in the shriveled state until adenosine triphosphate (ATP) binds to myosin, releasing the myosin and actin filaments from one another.

<h3>How long after a individual dies does rigor mortis set in?</h3>

Rigor mortis appears approximately two hours after dying in the muscle groups of the face, progresses to the limbs over the subsequent few hours, finishing between 6 to eight hours after death. [10] Rigor mortis then stays for some other 12 hours (till 24 hours after death) and then disappears.

<h3>Why does a body go into rigor mortis stiffen within 36 hours of death?</h3>

Rigor mortis is the 1/3 stage in which the muscle mass harden and become stiff, prompted with the aid of the lack of adenosine triphosphate (ATP), which gives electricity to the muscles. Rigor mortis is a extensive tool to any dying examination because it can narrow down the timeframe of death.
