To measure the diameter of a organelle with a scale line of 1 µm.
- Measure the length of the scale line on the micrograph in mm, e.g. 1 µm = 17mm.
- Measure the diameter of the organelle in millimetres, e.g. = 60mm.
- True diameter of organelle.
<h3>How do you find the actual size of an organelle?</h3>
To calculate the actual size of a magnified specimen, the equation is simply Mixed6 :
Actual = Image size (with ruler) ÷ Magnification.
Thus, this is how we can measure the size of an organelle.

Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
Hope this helped!

Answer:
Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.
