Answer: enzymes

Explanation:

Enzymes are the special protein molecules present in the cells of the living organism. Enzymes do not participate as reactants in a chemical reaction instead they speed up the chemical reaction. This is the catalytic property of the enzyme. A substrate binds to the active site of the enzyme and gets converted into product. They play important role in respiration, digesting food, muscle and nerve function.

On the basis of the above description, Specialized proteins which function as catalysts for organic reactions are: enzymes.

Calculate the gravitational force of attraction between a 26kg boy and his 5.1kg dog when they are separated by 0.19m

Pavel [41]

Answer:

Gravitational force of attraction G(f) = 2.44 x 10⁻⁷ (approx.)

Explanation:

Given:

Mass M1 = 26 kg

Mass M2 = 5.1 kg

Distance r = 0.19 m

Find:

Gravitational force of attraction G(f)

Computation:

Gravitational force of attraction G(f) = G(m1)(m2)/r²

Gravitational force of attraction G(f) = [6.67 x 10⁻¹¹](26)(5.1)/(0.19)²

Gravitational force of attraction G(f) = 8.84 x 10⁻⁹ / 0.0361

Gravitational force of attraction G(f) = 2.44 x 10⁻⁷ (approx.)

What data should be plotted to show that experimental concentration data fits a first-order reaction? A) 1/[reactant] vs. time B

natita [175]

Answer:

C) In[reactant] vs. time

Explanation:

For a first order reaction the integrated rate law equation is:

$A = A_{0}e^{-kt}$

where A(0) = initial concentration of the reactant

A = concentration after time 't'

k = rate constant

Taking ln on both sides gives:

$ln[A] = ln[A]_{0}-kt$

Therefore a plot of ln[A] vs t should give a straight line with a slope = -k

Hence, ln[reactant] vs time should be plotted for a first order reaction.

At the county fair, Carrie and Sam climbed up on the carousel horses. Around and around they went; the horses also bobbed up and

grigory [225]

I believe sam's response is correct.
When human is riding a moving target with constant speed over a period of time, we tend to have a visual acceleration perception due to our optical movement.
This make people such as Carrie believes that the carousel horses are accelerating while it actually stayed at constant pace.
