Answer:

A. Contain cells that connect to form pipes.

B. Transport water and food.

Explanation:

The vascular tissue is known to be conducting tissue which has more than one cell type. It is usually found in vascular plants. It is composed of xylem and phloem.

Their function is to transport fluid (like water) and other nutrients, therefore they have cells that connect to form pipes. The xylem and phloem occur together in vascular bundles in the plant organs passing through stems, leaves and roots.

I/3 of 12 = 2/3 of<br>please help at 11 o'clock am it needs to be done ​
Nostrana [21]

Answer:

6

Explanation:

This question is seeking for an equivalent of one expression. The first expression says 1/3 of 12, which means 1/3 × 12 = 4. To find 2/3 of a number that will give us 4, we say

Since; 1/3 of 12 is 4

Then, 4 = 2/3 of x, where x is the number, which when multiplied by two-third (2/3) will result to 4.

4 = 2/3 × x

4 = 2x/3

Cross multiply

2x = 3 × 4

2x = 12

x = 12/2

x = 6.

This means that; 1/3 of 12 = 2/3 of 6
