Cloud seeding
Another instance where supercooled and mixed-phase clouds are studied extensively is related to cloud seeding and weather modification. Cloud seeding involves the addition of aerosol, such as silver iodide aerosol, that modifies the phase and size distribution of hydrometeors. The goal of cloud seeding is to alter the natural development of the cloud to enhance precipitation, suppress hail, dissipate fog, or reduce lightning. Various cloud seeding techniques are employed, as particles are released from rockets, aircraft, or ground. The seeding of ice-phase clouds can induce the phase transition from a supercooled water cloud to one composed of ice. In the case of dynamic cloud seeding, the purpose is to stimulate vertical air motions through increased buoyancy caused by the release of latent heat of freezing (Hobbs, 1975; Cotton and Pielke, 1995).
Answer: Feeding behaviors, trophic levels, cell wall composition, and their organelles distinguish fungi from plants.
Explanation:
While plants and fungi are both eukaryotes, they differ in terms of feeding behaviors, trophic levels, cell wall composition, and their organelles.
- Cell walls: both are non-chain polysaccharides (sugars) that function as structural support; yet fungal cell walls are composed of chitin while plant cell walls are made up of cellulose
- Feeding: fungi secrete compounds that digest their food sources before they can take in nutrients and they store food as <em>glycogen; </em>while plants do not require a means of pre-digesting food and store their food as <em>starch.</em>
- Organelles: plant cells contain <em>chloroplasts</em>, small green structures with chlorophyll that causes their characteristic coloration. Unlike plants, fungi do not photosynthesize to make their own food or contain chloroplasts.
- Trophic level: are strictly <em>heterotrophs or decomposers, </em>depending on other organisms for survival. Their chloroplasts enable them to carry out photosynthesis, thus they are <em>autotrophs or producers. </em>
The chorion develops into the PLACENTA, a pancake-like structure that is attached to the endometrium and is about 7 inches in diameter and 1-2 inches thick.
Placenta is an organ present inside the uterus that contains the fetus and connects the fetus to the uterine wall of the mother. The fetus derives all the nutrients and food from the mother with the help of placenta.
Answer:
It produces a clear smooth liquid that combines with sperm to create semen
Explanation:
Answer:
List the features of gas exchange surfaces in animals.
1)They are moist to prevent the cells from drying and to allow gases to dissolve;
2)They have a large surface area , so that a lot of gas can diffuse across at the same time;
3)They have a high concentration gradient - maintained by the movement of air & blood.
