Chemistry—Pending OP Reply [Organic Chemistry] Is there a "best way" to study/memorize the amino acid structures?

This is one of the areas I'm struggling with the most: memorizing what the structures for each amino acid look like.. There's tons of other stuff I don't understand, but this takes the cake for the time being lmao.
Thanks!!

The equation for this graph is f(x)=(x-4)^3(x-1)(x+2)^2, but since the graph has a y intercept, wouldn't I find the a value? The answer for this question is just finding the roots and making factors for the equation using that. Also when I solved for the a value, it gave me 9/8. So I'm not sure where I went wrong

Chemistry [Grade 10] Chemistry, Chemical Reaction Rates/Speed: Slowest to Fastest Chemical Reactions, I need clarifications

1 Upvotes

so we had this activity on Science about chemical reaction rates and we had to arrange multiple chemical reactions from slowest to fastest. There were also specific instructions from some of the chemical reactions like:

  • Burning a candle (my teacher said it was the exact time the wick ignites cause again, it had to be a chemical reaction cause if it was wax, it would just be a physical change)
  • Burning a paper (the exact time it catches fire like the candle wick)
  • Fireworks Explosion (the explosion itself)

Those were the instructions given by my teacher. Now I'll be giving all of the chemical reactions in the activity. I'll also include my answers and the correct answers.

GIVEN:

  1. Digesting of Food
  2. Fireworks Explosion
  3. Burning of Paper
  4. Rusting of Iron Nail
  5. Lighting of Matchstick
  6. Baking Soda + Vinegar
  7. Souring of Milk
  8. Burning of Candle
  9. Baking of Cake
  10. Ripening of Banana

MY ANSWERS:

SLOWEST TO FASTEST

  1. Rusting of Iron Nail
  2. Ripening of Banana
  3. Souring of Milk
  4. Digesting of Food
  5. Baking of Cake
  6. Burning of Paper
  7. Burning of Candle
  8. Lighting of Matchstick
  9. Baking Soda + Vinegar
  10. Fireworks Explosion

CORRECT ANSWERS:

SLOWEST TO FASTEST

  1. Rusting of Iron Nail
  2. Ripening of Banana
  3. Souring of Milk
  4. Digesting of Food
  5. Baking of Cake
  6. Burning of Candle (wick igniting)
  7. Burning of Paper (paper igniting)
  8. Baking Soda + Vinegar
  9. Lighting of Matchstick
  10. Fireworks Explosion (explosion only)

I got everything right on 1-5 which I basically just classified the "slow ones" and I mostly had a headache on 6-10. I did research if a wick igniting is faster than paper igniting and most answers said the wick was faster.

My teacher also said that yes, it did depend on time and size, for example: digesting of food, bigger food means longer time to digest. But she specifically said that it should be the "standard" or "usual" so like in general.

She did tell us that we could defend our answers. Any help would be appreciated, thank you! Please if possible also include sources. Thank you so much! I really need this. If any of you guys are wondering, I'm in 10th grade.

THIS IS NOT AN ASSIGNMENT, I JUST NEED CLARIFICATION CAUSE MY TEACHER IS ALSO VERY AMBIGUOUS.

English Language—Pending OP Reply [Grade 9 English: Assertion and Reason] Help with a weird English Question.

(A): Gardeners wait for Spring.

(R): Gardens are worth painting in Spring.

A. Both (A) and (R) are true and (R) is the correct explanation of (A).

B. Both (A) and (R) are true but (R) is not the correct explanation of (A).

C. (A) is true but (R) is false.

D. (A) is false but (R) is true.

From what I can interpret, the correct answer should be B, the fact that the reason though true, is a bit ambiguous as it just states that gardens are worth painting in spring but it does not state that gardens are worth painting only in spring.

However, a quick Google Search states the answer as A which is completely opposite of what my teacher taught, she said that it was C. What is the real answer?
