Which of the following animals have long sticky tongues?
a)
eagles
b)
penguins
c)
cheetahs
d)
cows
|
Freak Artworks answered |
Long Sticky Tongues
The animal that has a long sticky tongue among the given options is the penguin.
Here is a detailed solution:
- Penguins: Penguins have long, thin, and sticky tongues that help them catch and swallow their prey, such as fish and krill. Their tongues are covered in backward-facing spines that help secure the prey and prevent it from slipping away.
- Eagles, cheetahs, and cows do not have long sticky tongues.
- Eagles: Eagles have sharp beaks and talons that they use to catch and grip their prey, but they do not have long sticky tongues.
- Cheetahs: Cheetahs have long, muscular tongues, but they are not sticky. They use their tongues to lick the meat off bones and groom themselves.
- Cows: Cows have long tongues, but they are not sticky. They use their tongues to gather grass and other vegetation for grazing.
Therefore, the correct answer is B: penguins.

Amar Patel answered • Dec 21, 2024 |
Understanding the Range
To find five rational numbers between -5/7 and -3/8, we first need to convert both fractions into decimal form for easier comparison.
- -5/7 ≈ -0.714
- -3/8 = -0.375
This means we are looking for rational numbers between -0.714 and -0.375.

(16)^7 × (25)^5 × (81)^3 ÷ (15)^7 × (24)^5 × (80)^3,?

Amar Patel answered • Oct 09, 2024 |
Understanding the Expression
The expression to simplify is:
(16)^7 × (25)^5 × (81)^3 ÷ (15)^7 × (24)^5 × (80)^3
This involves both multiplication and division of powers.
Step-by-Step Simplification
- Factorization of Each Number:
- 16 = 2^4
- 25 = 5^2
- 81 = 3^4
- 15 = 3 × 5
- 24 = 2^3 × 3
- 80 = 2^4 × 5
- R... more
- (2^4)^7 × (5^2)^5 × (3^4)^3 ÷ ((3 × 5)^7) × ((2^3 × 3)^5) × ((2^4 × 5)^3)
- Apply the Power of a Power Rule:
- 2^(4*7) × 5^(2*5) × 3^(4*3) ÷ (3^7 × 5^7) × (2^(3*5) × 3^5) × (2^(4*3) × 5^3)
- Combine and Simplify:
- Combine all similar bases together and simplify the expression.
Final Calculation
- Collecting the Powers:
- For 2: 2^(28 - (15 + 12)) = 2^1
- For 3: 3^(12 - (7 + 5)) = 3^0 (which equals 1)
- For 5: 5^(10 - (7 + 3)) = 5^0 (which equals 1)
Conclusion
After simplification, we find:
2^1 × 3^0 × 5^0 = 2
Thus, the final answer is 2.

Correctly Punctuated Sentence Explanation:
The correctly punctuated sentence is option 'B':
b) He did not like being told-off.
