Are endocytosis and exocytosis active or passive transport? Choices are : Active Passive The Correct Answer and Explanation is: Correct Answer: Active Explanation: Endocytosis and exocytosis are both examples of active transport processes. These mechanisms are used by cells to move large molecules or particles across the cell membrane, which cannot pass through by simple

which number is located between 1.2 and 1.4 The Correct Answer and Explanation is: Correct Answer:A number located between 1.2 and 1.4 is 1.3. Explanation:To find a number that lies between two given decimal numbers, such as 1.2 and 1.4, it helps to understand how decimal numbers work. Decimal numbers are based on the number

A tree is 119 inches tall. how tall is it in feet and inches The Correct Answer and Explanation is: Answer:A tree that is 119 inches tall is 9 feet 11 inches tall. Explanation (like in textbooks):To convert a measurement from inches to feet and inches, we use the fact that 1 foot equals 12
