Explanation:
density(d) = mass(m) × volume(v)
given:
mass = 4.3 g = 0.0043 Kg
volume = 2.7 cm³ = 0.027 m³
= 0.0043 Kg / 0.0027 m³
= 0.15 Kg/m³

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.
Answer:
1. Nonmetal
2. Nonmetal
3. Covalent
Explanation:
CH4 is the chemical formula for the methane molecule in which four atoms of hydrogen is chemically bonded to one atom of carbon. Both carbon, which is the first element and hydrogen the second element are non-metals, and hence can only form a covalent bond.
A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.
Answer:
369.4 g.
Explanation:
- The chemical reaction of reacting hydrogen with oxygen to produce water is:
<em>H₂ + 1/2 O₂ → H₂O.</em>
- From the law of conservation of mass states that <em>the mass does not destroyed or created from nothing but it can converted from from to another one.</em>
- The mass of the reactants = the mass of the products
∴<em> The mass of hydrogen + the mass of oxygen = the mass of water.</em>
∴ The mass of oxygen = the mass of water - the mass of hydrogen = (416.0 g) - (46.6 g) = 369.4 g.
