Will someone comment they cashapp after they answer these questions.
Rufina [12.5K]

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

Human beings have about 100,000 genes, and each has a single specific function. True or False
melomori [17]
I would go with false, because not only 100,000 genes, there are lots to those. and there are not even like 100,000 genes, that is not really possible!!
hope that this helps you! =)

Answer:

A group of parasites called myxozoans have traditionally been considered simple multicellular protists. However, because these organisms possess stinging cells, some scientists consider them to be animals in the phylum that is named for such cells, the <u>cnidarians</u>.

Explanation:

Cnidarians are animals with radial symmetry, that is, their bodies can be divided, by different planes, into equal parts. It includes hydras, jellyfish, anemones and marine corals. Its body is a kind of sac with an opening (the mouth) surrounded by a circle of tentacles. Some have a dominant jellyfish phase, others polyp, or both. They present defensive nematocysts with stinging action.
