Answer:
Detail is given below.
Explanation:
Given data:
Mass of enzyme = 32 g
Volume of water = 42.50 mL
Volume of water+ enzyme = 48.0 mL
Density of enzyme = ?
Solution:
Density is equal to the mass divided by volume.
First of all we will calculate the volume of enzyme.
Volume of enzyme = (volume of water+ enzyme ) - Volume of water
Volume of enzyme = 48.0 mL - 42.50 mL
Volume of enzyme = 5.5 mL
Density of enzyme:
d = 32 g/ 5.5 mL
d = 5.8 g/mL
2)
Given data:
Mass of cup = 14 g
Volume of cup = ?
Density of cup = 2 g/cm³
Solution:
Density is equal to the mass divided by volume.
Formula:
d = m/v
2 g/cm³ = 14 g/ v
v = 14 g/2 g/cm³
v = 7 cm³
3) What are the four ways to measure matter?
weight, mass, volume, density
4) Given data:
Mass of rock = 18.5 g
volume of rock = 3cm³
density of rock = ?
Solution:
Formula:
d = m/v
d = 18.5 g/ 3cm³
v = 6.16 g/cm³
5)
Given data:
mass = 6g
density = 8 g/cm³
missing value = ?
Solution:
d = m/v
8 g/cm³ = 6g / v
v = 6g/8 g/cm³
v = 0.75cm³
6)
Given data:
Volume of liquid in cylinder = 48 mL
Volume of toy car and liquid = 52 mL
Volume of car = ?
Solution:
Volume of car = volume of of toy car and liquid - Volume of liquid in cylinder
Now we will put the values.
Volume of car = 52 mL - 48 mL
Volume of car = 4 mL

Mould growing on a tomato that is sitting on a countertop be used as evidence for the spontaneous generation theory.
<h3>What do you mean by spontaneous generation theory?</h3>
According to the hypothesis of spontaneous generation, the emergence of life things from nonliving materials was both common and predictable. It was proposed that some forms, like fleas, may develop from inanimate substances like dust or that maggots could develop from decomposing human flesh.
In addition to causing postharvest rot during harvest and storage, a gray mold of tomatoes can also spread a number of other diseases, such as damping off and blight. A fungus with a host range of over 200 plants causes gray mold on tomato plants. It will be evidence for spontaneous generation theory.
