Which statement correctly compares mass and weight?

hram777 [196]

Answer:

D. Weight varies with location, but mass does not vary

Explanation:

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

$Weight = mg$

Where;

m is the mass of the object.
g is the acceleration due to gravity.

Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.

Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).

<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>

Liono4ka [1.6K]

Answer:

Gender roles are necessary to keep the family in balance.

Explanation:

Functionalists perspective of gender roles view conventional gender roles as necessary to commit to family functioning as it tends towards keeping the family balance: Women take on the “expressive” character of putting up with household chores and giving emotional care, grooming and nurturing of family members, while men take on the “instrumental” character of acquiring income and undertaking important family decisions.

Hexokinase can use glucose or fructose as a substrate. The Km forglucose is 0.15 mM and for fructose Km = 1.5 mM.

babymother [125]

Answer:

a) glucose because Km is less for glucose.

b) For glucose, V as a percentage of Vmax = 50 %

For fructose, V as a percentage of Vmax = 9 %

Explanation:

a) Hexokinase has highest affinity for glucose because it's Km for glucose is low.

When enzyme [E] binds a substrate [S] an [ES] complex is formed. It is represent as under:

[E] + [S] ⇌ [ES] ⇌ [E] + [P]

As soon as [ES] is formed it may either form [E] & [P] in a forward reaction or dissociate back into [E] & [S]. Km is known as dissociation constant which represents the extent to which [E] & [S] are being formed. A higher value of Km represents formation of more [E] & [S] back from [ES]. It also means that binding affinity of enzyme with substrate is less or we can say that Km is inversely proportional to binding affinity.

Km ∝ 1 / binding affinity.

So, it simply means that lower the Km more will be the affinity of the enzyme for the substrate. In the given question, Km for glucose is 0.15 mM which is less than fructose (Km for fructose = 1.5 mM) that is why glucose is the answer.

b) The formula for Michaelis–Menten equation is as under:

V = Vmax × [S] / ([S] + Km)

V / Vmax = [S] / ([S] + Km)

Here, for glucose Km = 0.15 mM and [S] = 0.15mM.

So V as a percentage of Vmax for glucose will be as under:

V / Vmax = 0.15/0.15 + 0.15

→ V / Vmax = 0.15/0.30

→ V / Vmax = 0.5 = 1/2 = 50 %

Here, for fructose Km = 1.5 mM and [S] = 0.15mM.

So V as a percentage of Vmax for fructose will be as under:

V / Vmax = 0.15/0.15 + 1.5

→ V / Vmax = 0.15/1.65

→ V / Vmax = 0.09 = 9/100 = 9 %
