Explanation:
Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all. A few lipophilic substances move freely across the cell membrane by passive diffusion. ... Large molecules do not cross intact cell membranes, except in certain special cases.
Sternal angle marks the joint between the sternum and the 2nd rib.
Option E.
<h3><u>Explanation:</u></h3>
Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.
The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.
B, C, D
A is r-selected species
Answer:
4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D. 
> <em>NADP </em>> <em>Calvin cycle.</em>
- Electron is first provided to the photo-system II by the phtolysis of water.
- Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome
. - Finally, electron from the photo-system II is used to reduce NADP to NADPH.
- NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.
5. The correct answer is B.) photosynthesis.
- Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
- In light independent phase of photosynthesis, it requires ATP and NADPH in order to synthesize food.
- Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.
