Answer:
A. Tissue
Explanation:
The cells join together to form tissues. So, option (A) is the correct answer.
1 kilometer = 6.68 ×
(<<<AU is in scientific notation here)
To convert 300 billion kilometer (3,000,000,000 km) into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 ×
)
3,000,000,000 × (6.68 ×
) = 20.04 AU
Hope this helped!
