0. Give an example of how an organism can use surface tension.
Answers
Answer:
In case of plants surface tension help to support the transpiration pull.
Explanation:
Surface tension is a force that hold the molecules in the surface to minimize the surface area.
During evaporation of excess amount of water from the stomata of leaves of plants by transpiration a surface tension is generated.
The generated surface tension helps to maintain the water column within the xylem tissue by the absorption of water from the soil by the roots.

find angle ABE.
Answers
Answer:
The measure of angle ABE is 27°.
Explanation:
Consider the below figure attached with this question.
Given information: ∠ABE=2n+7 and ∠EBF=4n-13.
From the below figure it is clear that ∠ABE and ∠EBF are congruent.
Isolate variable terms on one side.
Divide both sides by 2.
The value of n is 10.
We need to find the measure of ∠ABE.
Therefore, the measure of angle ABE is 27°.
The measure of angle ABE is 27°.
Since the angles are congruent, therefore, ∠ABE=2n+7 and ∠EBF = 4n-13 will be equated to each other.
This will be;
2n+7 = 4n-13
Collect like terms
4n-2n = 7+13
2n = 20
Divide both sides by 2.
2n/2 = 20/2
n = 10
Therefore, the value of n is 10.
Since angle ABE = 2n + 7
ABE = 2[10] + 7
= 20 + 7 = 27°.
Therefore, the measure of angle ABE is 27°
