Neutrons for example isotopes
Answer: 2 atoms
Explanation: A molecular formula of the compound carbon dioxide is CO 2 . One molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of oxygen.
Answer:
<u>The complete question is:</u>
A researcher is using a small molecule inhibitor to manipulate a signaling pathway. This inhibitor prevents phosphorylation and most likely targets
a: phosphatase.
b: ligand-gated ion channel.
c: G protein-coupled receptor.
d: G-protein.
e: receptor kinase.
<u>The correct answer is:</u>
e: receptor kinase.
Explanation:
Kinase is the enzyme that add phosphate groups by transferring them from molecules having high energy (i.e. ATP) to target compound and the process of adding phosphate groups to the target compound is called phosphorylation.
In light of the above explanation, it is clear that kinase is the type of enzyme that involves in phosphorylation therefore, if an inhibitor prevents phosphorylation, it will automatically targets receptor kinase to inhibit the process of phosphorylation.
The symbols that will complete the equation for single displacement reaction is 2NaCl + Br2
Explanation
The balanced equation is as below
2NaBr + Cl2→ 2NaCl + Br2
A single displacement reaction is type of reaction in which element react with compound and take place of other element in that compound.
Mostly the more reactive element displaces the less reactive elements from its compound.
Chlorine (Cl2) is more reactive than bromine(Br2) therefore chlorine displaces bromine from its compound.
P*V=n*R*T where p is the pressure, v the volume in L, n the quantity in moles, R a standard number that should be given and T the temperature in Kelvin
R=8.32 (usually)
T(in K)=273+T(in Celsius) so T=296K
P*V=n*R*T
P=n*R*T/V
P=0.4*8.32*296/0.2
