Answer:
<u>Searching For Facts</u>
- You must first begin surfacing the net or other sources for facts about the Topic provided.
- It also quite depends on the size of the scientific report you are preparing. (It is usually large about 4000 words).
- If you are abundant with information, about the topic, write To-The-Point.
- If there is a lack of information, try to expand about a sub-topic whilst including new facts about the same.
<u>Constructing a report:</u>
- You can start with an appropriate title about your topic, just ensure that it doesn't go too long.
- Begin the report with a short introduction about the report. If you are noting an experiment, include the apparatus required.
- The body should provide a detailed description about the topic. You may use tables or paste images in the report.
- If it's a report about an experiment, don't forget to write down the observations.
- Lastly, a conclusion with a brief thought derived, must be included in the report.
- If necessary, attach the References in the report too.
Answer:
D. Increasing the amount of food bought locally
Pinching in of fluids by a unicellular organism is the process of pinocytosis or fluid endocytosis. The cell takes in surrounding fluids, including all of the substances available, without differentiating. It is a non-specific process. The membrane of the unicellular organism elongates, captures the fluid and small vesicles are pinched off intracellularly. These vesicles then are processed by the organelles of the cell.
Answer:
According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>
<u />
Thus the rate at which oxygen will move across the phospholipid bilayer will depend on the concentration or amount per mole of the oxygen molecule hitting the phopholipid at a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules increases.
Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid bilayer should also be maximized. the distances between the phopholipid and the vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law has been applied , and therefore maximum oxygen molecules can diffuse across.
