If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm

You start by answering the first question on the list which tells you what to do from there. Pretend your animal was a bird, you might have a key like this:
Does this animal have wings?
yes go to question 2
no go to question 6
Then you just continue until the list doesn't say to do anything else. i.e.:
Is the animal feathered?
yes bird
no go to question 4
A. Both strands of the DNA molecule act as templates
Answer:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

Answer:
B is the correct option because, in a cell, <u>only mitochondria</u> generate and provide <u>energy</u> for muscle movement.
Explanation:
Mitochondria are known as a powerhouse of the cell because they perform <u>cellular respiration</u> and <u>generate energy as an ATP</u> (Adenosine Triphosphate) molecule. <u>Muscle cells function in movement and burn more energy that's why they have many mitochondria to fulfill energy demands.</u>
On the other hand, options <u>A, C, and D are not correct options </u>because mitochondria do not perform other services such as acting as protein factories, linker cells, nutrients transportation. The activities are performed by other organelles.
