Answer: d. Does sugar or salt have a greater effect on plant growth?

Explanation:

A scientific question is said to be reproducible if it can be answered by many scientists on the basis of either applying similar, improvised or different methodologies.

d. Does sugar or salt have a greater effect on plant growth? is the correct option. This is because the sugar and salts are the two independent variables whose affect is to be measured on the test variable or dependent variable that is plant growth. This question can be answered using suitable methodologies and by different scientists as the question is testable.

Lady bird [3.3K]

Answer:

Tissue

Explanation:

A cell is a structure formed during the evolution which contained all the molecules and favourable conditions required to survive and therefore acts as the functional and structural unit of life.

In evolution, more than one cell aggregated together to form a structure which could perform much complex function than a single cell called tissue as they are programmed to perform the same function.

In the given question, since the heart cells worked together to cause movement in the robot therefore the cardiac cells formed cardiac tissue or heart.

Thus, the tissue is the correct answer.
