Answer:
You will be able to tell whether the unknown cell is from an animal or from a plant through the knowledge of difference between plants and animal cells.
Explanation:
A cell can be defined as the simplest bit of living matter which exhibits a variety of shapes and sizes and that can exist independently.
When a slide of an unknown cell is studied under a microscope, different cell structures would be observed which would be used to conclude if the cell on the slide is a plant or animal cell.
The following features are observed in a plant cell:
--> cellulose cell wall is present
--> Chloroplast is present
--> A large central vacuole is present
--> Centriole is absent
The following features are observed in animal cell:
--> Cellulose cell wall is absent
--> Chloroplast is absent
--> Small vacuoles is present
--> Centriole is present
The difference between a plant and an animal cell can be seen from the features above and a clear knowledge of this will help the student tell whether the unknown cell is from an animal or from a plant.
The answer is A. the same.
Since the container is sealed, their will be no loss of material from the container which means that the mass won’t vary.
It pulls the moon toward earth
For the answer to the question above, we have to use this formula
Pressure = P = force / area
Then, just substitute the values of the formula
force = mg = 2(10) = 20 N
area = A = 1 cm² = [1 x 10 ̄ ²]² m²
=> P = 20 N / [1 x 10 ̄ ²]² = 200 x 10³ Pa
= 200 kPa
I hope my answer helped you. Have a nice day!
