MathGPT Pro | MathGPTPro said:

Close! 👍 The correct answer is C) Smooth muscle.

Here’s the breakdown:

• Smooth muscle (C) → involuntary, found in organs like stomach, intestines, blood vessels.

• Cardiac muscle (B) → also involuntary, but only in the heart.

• Skeletal muscle (A) → voluntary, moves bones.

• Connective tissue (D) → supports and binds tissues (not muscle at all).

👉 Trick: Smooth = stomach & organs.

🔬 TEAS Science Quiz – Question 7

Which organelle contains digestive enzymes that break down waste inside the cell?

A) Nucleus
B) Ribosome
C) Lysosome
D) Mitochondrion

---

👉 What’s your answer?

You said:

d

MathGPT Pro | MathGPTPro said:

Almost 😅 but the correct answer is C) Lysosome.

Here’s why:

• Lysosome (C) → contains digestive enzymes that break down waste, old cell parts, and foreign invaders.

• Mitochondrion (D) → “powerhouse,” makes ATP, not digestion.

• Nucleus (A) → stores DNA, controls cell activities.

• Ribosome (B) → makes proteins.

👉 Trick: Lysosome = Lysol → cleans up the cell. 🧽

🔬 TEAS Science Quiz – Question 8

Which blood type is considered the universal donor?

A) A+
B) O+
C) AB+
D) O−

---

👉 What’s your answer?

You said:

b

MathGPT Pro | MathGPTPro said:

Almost! 👍 The correct answer is D) O−.

Here’s why:

• O− (O negative) → universal donor because it has no A, B, or Rh antigens on its red blood cells → can be given to any blood type safely.

• O+ (B) → can only donate to positive blood types (not universal).

• AB+ (C) → universal recipient, not donor.

• A+ (A) → can donate only to A+ or AB+.

👉 Trick: O− gives to everyone, AB+ receives from everyone.

🔬 TEAS Science Quiz – Question 9

What molecule carries genetic information in cells?

A) RNA
B) DNA
C) ATP
D) Protein

---

👉 What’s your answer?

You said:

b

MathGPT Pro | MathGPTPro said:

✅ Correct! 🎉

Answer: B) DNA

• DNA (deoxyribonucleic acid) → stores and transmits genetic information.

• RNA (A) → helps in protein synthesis (messenger, transfer, ribosomal), but not the main storage of genetic info.

• ATP (C) → cell’s energy currency.

• Protein (D) → performs functions but instructions come from DNA.

👉 Trick: DNA = Directions for life.

🔬 TEAS Science Quiz – Question 10

Which part of the heart pumps oxygenated blood to the body through the aorta?

A) Right atrium
B) Left atrium
C) Right ventricle
D) Left ventricle

---

👉 What’s your answer?

You said:

d

MathGPT Pro | MathGPTPro said:

✅ Absolutely correct! 🎉

Answer: D) Left ventricle

• Left ventricle → pumps oxygenated blood into the aorta, sending it throughout the body.

• Right atrium (A) → receives deoxygenated blood from the body.

• Left atrium (B) → receives oxygenated blood from the lungs.

• Right ventricle (C) → pumps deoxygenated blood to the lungs.

👉 Trick: Left ventricle = Largest, strongest pump → body.

Q3: Mitosis – which phase has chromosomes lined up in the middle?

• You answered: A) Prophase

• Correct answer: B) Metaphase

• 🔑 Trick: Meta = Middle. Chromosomes line up in the middle of the cell during metaphase.

❌ Q4: Which system transports hormones in the body?

• You answered: A) Lymphatic system

• Correct answer: C) Circulatory system

• 🔑 Trick: Endocrine system makes hormones, Circulatory system moves them through blood.

---

❌ Q5: What happens to diaphragm during inhalation?

• You answered: C) Contracts and moves upward

• Correct answer: A) Contracts and moves downward

• 🔑 Trick: Inhale = chest expands = diaphragm pushes down to make space for lungs.

---

❌ Q6: Which RNA carries amino acids to ribosome?

• You answered: A) mRNA

• Correct answer: B) tRNA

• 🔑 Trick:

  • mRNA = message (code from DNA)

  • tRNA = transfer (carries amino acids)

  • rRNA = ribosome (structure)

---

❌ Q10: Two heterozygous parents (Rr × Rr) — probability child has disorder?

• You answered: B) 50%

• Correct answer: A) 25%

• 🔑 Trick: Punnett square:

  • RR = 25% (healthy)

  • Rr = 50% (carrier)

  • rr = 25% (disorder)

 The mitochondrion (answer B) is the “powerhouse of the cell” because it produces ATP (adenosine triphosphate) through cellular respiration.

• Ribosome → makes proteins, not energy

• Endoplasmic reticulum → helps with protein & lipid synthesis

• Lysosome → breaks down waste

• 🔬 TEAS Biology Question 2:

  If a DNA strand has the sequence:
  5’-ATCGTACG-3’,

  what is the complementary strand?

  A) 5’-TAGCATGC-3’
  B) 3’-TAGCATGC-5’
  C) 5’-UAGCAUGC-3’
  D) 3’-UAGCAUGC-5’

  ---

  👉 What’s your answer?

  (We’ll check and explain before moving to Question 3.)

  If you’d like, I can also show you a shortcut method to always find complementary DNA strands. Would you like me to include that in the explanation?

  You said:

  MathGPT Pro | MathGPTPro said:

  ✅ Correct again! 🎉

  The complementary DNA strand is 3’-TAGCATGC-5’ (answer B).

  Here’s why:

  • DNA follows base-pairing rules:

    • A ↔ T

    • C ↔ G

  • The given strand is 5’-ATCGTACG-3’.

  • Pairing each base:

    • A → T

    • T → A

    • C → G

    • G → C

    • T → A

    • A → T

    • C → G

    • G → C

  That gives: TAGCATGC.
  Since DNA strands are antiparallel, the complementary strand must be written 3’ → 5’.

Question 7 of 38

Solve:

358×225

• 7916
• 614
• 1087
• 8710

End Quiz

Answer Explanation

Incorrect

---

Step 1: Convert the mixed numbers into improper fractions

358=3×8+58

=298

 

225=2×5+25

=125

 

358×225 now becomes  298×125

Step 2: Cross Simplify [If Applicable] and multiply
When we look at the fractions to cross-simplify, we find that 12 and 8 have a common factor of 4. We can now reduce the fraction by 4. 

298×125=29×(12÷4)(8÷4)×5

=29×32×5

=8710

Step 3: Simplify [If Possible] and convert into a mixed number
Convert the improper fraction into a mixed number.

8710=87÷10

8710

Answer: 8710
