ANY DIFFERENCE? 🤔
Osmosis = movement of WATER through a semipermeable membrane
Diffusion = movement of PARTICLES from high concentration to low concentration

Both are about moving from high to low, but only one needs a membrane and water 👀

Alternate angles don't have to be confusing 😮‍💨
Look for the N shape 👀 That’s alternate angles right there.
And the 2 pedals of a bicycle 🚲 That’s alternate angles too.
When lines are parallel, those angles are equal.
That’s why x = 70° and y = 120°.

Now it’s your turn 👇
Try the 3rd question "TRY THIS" and drop your answer in the comments.
Let’s see who gets it!

"ALTERNATE ANGLES HAVE NICKNAMES 😂
We call them:
Pedaled Angles
Z-Angles
N-Angles
Reversed Z-Angles

But the definition is SACROSANCT:

They are equal angles on opposite sides of a transversal
and inside the two lines.

2 CONDITIONS MUST BE MET:
1. The two lines must be PARALLEL ||
2. They must be cut by a TRANSVERSAL

If lines are not parallel → Angles are NOT equal ❌

See the Z? That’s alternate angles 🔄

CAN YOU DEFINE 1 JOULE? 🤔

Here’s the sacrosanct answer:

1 Joule of Work =
1 Newton of Force x 1 Meter of Distance
in the direction of the force.
That’s it. That’s the definition.
Unit: Joules or Newton-meter[J][Nm]

If the object doesn’t move,
You did ZERO work.

WORK in 30 seconds ⚡
Work = Force x Distance
Condition: The point of application of force MUST move
Derived Unit: Newton-meter (Nm)
SI Unit: Joule

No movement = No work. Period.

BIOLOGY QUESTION ALERT! 📌

Q: Which of the following is correct of OSMOSIS?
A) Water moves from concentration of low solute to high solute
B) Water moves from concentration of high solute to low solute
C) Neither A nor B is correct

This question has come in WAEC/NECO before 😤
Don’t forget: Osmosis = Movement of WATER

Drop your answer A, B, or C in the comments 👇
I’ll post the explanation later and attend to you personally. Here comes opportunity to always clear your doubt by interacting with the author.

How to solve -3² and (-3)² in 10 seconds

Don’t fall for this 😅

STEP 1:
-3² → No bracket. Square only the 3.
3² = 9. Then add the negative.
Answer: - 9

STEP 2: BRACKET MEANS EVERYTHING
(-3)² → There’s a bracket. Square -3 too.
-3 × -3 = +9
Answer: +9 or simply 9 ✅

The difference? 1 small BRACKET 😩

Remember: Bracket changes everything.

Comment your answer to this:
-9² = ?
(-9)² = ? 👇

Pop Quiz! 🧪
‎What’s the correct way to write Sodium Chloride?
‎
‎A lot of students miss this in WAEC/NECO because of 1 small rule 👇
‎FIRST letter CAPITAL, SECOND letter small.
‎
‎Na = Sodium
‎Cl = Chlorine
‎So together = NaCl ✅
‎
‎How many got D? Be honest 😂
‎Drop "I got it" if you did! 👇
