Transpiration in plants requires adhesion of water molecules to cellulose, cohesion between water molecules, evaporation of water molecules and transport through tracheids. Cohesion between water molecules is as a result of hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule. Transpiration involves the release of water through the leaves in pores called stomata, this serves as a method of excretion of excess water and diffused gases.
Answer:
Because the repetition of the experiment yields different results when they are realized by distinct groups of students
.
Explanation:
The students needs to repeat the experiment and increase the value of n (sample size) in order to obtain statistically significant results and thus confirm the working hypothesis.
The cytoplasm contains organelles. The organelles in this list surrounded by the cytoplasm would be the endoplasmic reticulum, lysosomes, and vacuoles. The cell wall and cell membrane are outside the cytoplasm. The nucleus would also be considered in the cytoplasm. If it's talking about a human cell, then chloroplasts would not be in the cytoplasm. Only in plant cells.
Answer: B/C/E/F and possible A if its talking about a <u>plant cell</u>

responses to eliminate the stress.
The digestive tract is a part of the body very commonly affected by stress.
