Answer 1

Answer:

The correct response to this question is Gravitropism.

Explanation:

Gravitropism is the directional growth response of plants to the force of gravity. When a seed is planted, the root of the plant grows downward and the shoot grows upward, even in darkness. If the seed is planted upside down, the geotropic response of the root causes it to grow upward initially, against gravity, until it senses the pull of gravity and then it will turn and grow downward. This process is known as negative gravitropism as the root grows against the direction of gravity at first, but eventually turns to grow in the correct direction.

Third Mean = 6

Fourth Mean = 9

Explanation:

For each column you just add up the data numbers and divide them by how many numbers is in that column which would be 3.

0.5 + 14.0 + 0.5 = 15 | 15 / 3 = 5

2.5 + 4.0 + 2.5 = 9    | 9 / 3 = 3

6.0 + 7.0 + 5.0 = 18   | 18 / 3 = 6

8.0 + 10.0 + 9.0 = 27 | 27 / 3 = 9

First= 5
Second= 3
Third= 6
Fourth= 9
