When the photosynthesis occur the extra food of plant store in Ground
Answer: The first part is wire mesh and bolts, the second one is NOT air pressure
Explanation:
Answer:
Abiotic factors can be described as the non-living components of an ecosystem. Biotic factors can be described as the living components of an ecosystem.
Abiotic factors include all the non- living components such as the weather, climate, temperature, soil, water of an area.
Biotic components include all the living organisms like the plants, animals, microorganisms of an ecosystem.
Hence, abiotic factors best describe the temperature and weather conditions of an organism's environment.
Answer:
c. a high percentage of very long chain saturated fatty acids
Explanation:
Saturated fatty acids do not have double bonds (they are saturated with hydrogens), so their tails are relatively straight. Unsaturated fatty acids, on the other hand, contain one or more double bonds, which often produces an elbow or bend. (You can see an example of an unsaturated bent tail in the phospholipid structure diagram that appears at the beginning of this article.) Saturated and unsaturated phospholipid fatty acid tails behave differently when the temperature drops:
- At colder temperatures, the straight tails of saturated fatty acids can be tightly bound, producing a dense and quite rigid membrane.
- Phospholipids with unsaturated fatty acid tails cannot bind so closely due to the bent structure of their tails. For this reason, an unsaturated phospholipid membrane remains fluid at lower temperatures than a saturated phospholipid membrane.
Most cell membranes contain a mixture of phospholipids, some with two saturated (straight) tails and others with a saturated tail and an unsaturated (folded) tail. <u>Many organisms — fish, for example — can adapt physiologically to cold environments by changing the proportion of unsaturated fatty acids in their membranes, that is, increasing the proportion of saturated long-chain fatty acids.</u>
In addition to phospholipids, animals have an additional component in their membrane that helps them maintain fluidity. Cholesterol, another type of lipid that is embedded between the membrane phospholipids, helps decrease the effects of temperature on fluidity.
Answer: When cells swell up
Explanation: Plants need carbon dioxide and <u>stomata allow the plant to take in carbon dioxide to perform photosynthesis</u>. The "lips" are actually individual cells (called guard cells) <u>that can swell up to open the stomata</u> or deflate to close them off.
