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
Answer:
Selective transport enables the substances to move rapidly through the cell membrane (for instance, H2O, O2 and CO2), while other substances pass through the cell membrane more slowly. Moreover, there are also compounds that can't pass through this barrier.
Explanation:
The selective transport of the substances across the cell membrane enables the cell to maintain the homeostasis of the system by maintaining the ionic equilibrium on both sides of the cell membrane. Moreover, selective transport also is required for carrying out cellular mechanisms, since this mechanism enables the entry and the exit of macromolecules used by the cell to maintain its function and structure.
The most common mechanisms of selective transport are diffusion and transport active. Endocytosis and exocytosis are active transport process where proteins, lipids, and different types of macromolecules are transported to both sides of the cell membrane through vesicles. Polar molecules (such as for instance, calcium and iron ions) may be transported via transport active, while hormones and vitamins may be transported via passive diffusion.
Answer:
The primary function of the pigment during the process of photosynthesis is to absorb maximum light energy which is necessary for the process
