Chloroplast is a part in a plant cell. It is the site at which photosynthesis occurs (light energy converted into oxygen).
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).
An endergonic reaction, like photosynthesis, refers to a reaction, which needs the energy to be driven. The activation energy for the reaction is usually greater in comparison to the entire energy of the exergonic reaction. The endergonic reactions are non-spontaneous.
In the given case, in order to accomplish the process, the coupling of the endergonic reaction, that is, thermodynamically unstable reaction with an exergonic, that is, the thermodynamically stable reaction is done so that the entire free-energy change of the coupled reactions becomes negative.
Answer:
C. meteorology
Explanation:
meteorology is the scientific study of the atmosphere that focuses on weather processes forecasting, and climate.
The theory of evolution can be proved by the comparison of DNA genetic sequences of organisms.
<u>Explanation:</u>
The evolution can be proved by following
- Homologous organs - they are organs that have similar basic structure but perform different functions. example: Human, Bird.
- Analogous organs-they are organs that perform same function but have different structure or basic design. example: Bird and insect.
- Fossils- the remains of dead animals and plants.
Dead organisms get decomposed by microbes, due to the absence of oxygen and moisture some body parts does not decompose.
The soft parts of body gets decomposed hard parts take time to decompose and get covered by sea, at these deep levels the decomposition stops and the hard parts remain preserved called fossils.
