Answer:
The bulk of water absorbed and transported through plants is moved by negative pressure generated by the evaporation of water from the leaves (i.e., transpiration) — this process is commonly referred to as the Cohesion-Tension (C-T) mechanism.
Explanation:
Answer: the answer your looking for is A
Explanation:
The incorporation of valinomycin, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective electrode that is highly selective for potassium.
<h3>How Valinomycin Ionophores Enter and Transport K+ across Model Lipid Bilayer Membranes?</h3>
- A biomimetic lipid membrane attached to the surface of the gold electrode contained the cyclic peptide valinomycin.
- The ionophore characteristics of the peptide were investigated using electrochemical impedance spectroscopy, and the conformation and orientation of the antibiotic valinomycin within the membrane were identified using polarization modulation infrared reflection absorption spectroscopy.
- By forming a complex with potassium ions and an ion pair with a counter anion, valinomycin transports ions across the membrane, and the combination of these two techniques revealed novel information about the ionophore mechanism.
- The ion pair is located inside the hydrophobic portion of the membrane and makes a little angle of around 22° with the surface normal.

A <u>Scientific method </u>is a series of steps used to determine solutions based on needs and wants.
<h3>What is needs assessment?</h3>
A needs assessment is a process that bridges the gap between an organization's current state and the desired conditions. It is a systematic procedure for identifying and addressing performance gaps as well as repairing any defects that may occur in an organization.
<h3>What are the six steps of the scientific method?</h3>
- Describe the issue :Observation with intent
- research : learn more about the subject
- educated guess : hypothesis forecast the outcome of the problem
- experiment :Create a procedure for testing the hypothesis.
- analyze :Keep track of the experiment's outcomes.
- conclusion : compare the hypothesis to the results of the experiment
<h3>What are the Characteristic Features of Scientific Methods?</h3>
- Students learn to identify and formulate scientific problems correctly and in an organized manner using scientific methods.
- Students are trained in information processing techniques using scientific methods.
- Scientific methods help students develop the ability to think critically and rationally, allowing them to make decisions on logical and rational grounds.
