aproximadamente dos mil
Explanation:
masa_proton/masa_electron=
1.673e-24 / 9.11e-28 = 1836.443468715697
Answer:
The correct answer is a Receptor ubiquitinylation mechanism is most likely to irreversibly terminate a signal transduction pathway.
Explanation:
Cell signaling or signal trasduction is phenomenon that regulates all physiological and biochemical processes that occur inside our body.Cell signaling take place by the binding of signaling molecule to a specific receptor.
It is also very much important to terminate the signaling pathways after the physiological or biochemical process is completed to maintain body"s normal homeostasis.
Irreversible termination of signal transduction means signaling pathway that is terminated cannot be reversed for further activation. Receptor ubiquitinylation or destruction of receptor by ubiquitin proteins and its associated enzymes helps to irreversibly terminate a signal transduction pathway.
Since the number on top is the mass number (number of neutrons and protons) while the number at the bottom is the atomic number ( number of protons)
A) 13 protons, 14 neutrons (27-13)
For the number of electrons it has to be equal to the number of protons if the atom is uncharged.
Therefore you have 13 electrons.
B) 17 protons, 18 neutrons (35-17)
18 electrons
C) What is the atomic number of Sulphur - need slightly more info
The number of mole of tin (Sn) that you have is 0.058 mole
<h3>Avogadro's hypothesis </h3>
6.02×10²³ atoms = 1 mole of tin (Sn)
With the above information, we can obtain the number of mole ot tin. Details below
<h3>How to determine the mole of tin that contains 3.5×10²² atoms</h3>
We can obtain the number of mole of tin as follow:
6.02×10²³ atoms = 1 mole of tin (Sn)
Therefore,
3.5×10²² atoms = (3.5×10²² atoms × 1 mole) / 6.02×10²³ atoms
3.5×10²² atoms = 0.058 mole of tin (Sn)
Thus, the number of mole of tin (Sn) you have is 0.058 mole
