Answer:
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. ... Once the light reactions have occurred, the light-independent or "dark" reactions take place in the chloroplast stroma.

True, a person can have two conflicting attitudes.
The correct answer is C. It is so strict because a foreign species could compete with a native species and drive it to extinction.
The Hawaiian islands are one of the geographical isolated islands which faces the problem of the invasive species affecting the biodiversity of the island negatively.
The foreign species is equipped better to survive in the Hawaiian habitat and competes with the native species for the resources and food. The interaction and competition of the foreign species in the Hawaiian environment and habitat limits the resources for native species which increases the chance of the native species getting endangered.
The Hawaii Invasive Species Council along with other bodies such as department of agriculture, department of business and economic development, private and other government and non-government bodies have taken initiatives towards eradication of invasive species by strict laws.
Betta fish are also known as Siamese fighting fish.They flare their gills when they are ready to fight. This makes them appear larger since fish do not have very good eyesight. They also fan their gills when they are trying to court a female Betta. ... Bettas are one of the few fish that can get air from above the water.
Answer:
Transmission electron microscope (MET): allows sample observation in ultra-thin sections. A TEM directs the electron beam towards the object to be increased. A part of the electrons bounce or are absorbed by the object and others pass through it forming an enlarged image of the specimen. To use a TEM, the sample must be cut into thin layers, not larger than a couple thousand thousands of angstroms. A photographic plate or a fluorescent screen is placed behind the object to record the enlarged image. Transmission electron microscopes can increase an object up to a million times.
A scanning electron microscope creates an enlarged image of the surface of an object. It is not necessary to cut the object into layers to observe it with an SEM, but it can be placed in the microscope with very few preparations. The SEM scans the image surface point by point, unlike the TEM, which examines a large part of the sample each time. Its operation is based on traversing the sample with a very concentrated beam of electrons, similar to the scanning of an electron beam on a television screen. The electrons in the beam can disperse from the sample or cause secondary electrons to appear. Lost and secondary electrons are collected and counted by an electronic device located on the sides of the specimen. Each point read from the sample corresponds to a pixel on a television monitor. The higher the number of electrons counted by the device, the greater the brightness of the pixel on the screen. As the electron beam sweeps the sample, the entire image of it is presented on the monitor. Scanning electron microscopes can enlarge objects 200,000 times or more. This type of microscope is very useful because, unlike TEM or optical microscopes, it produces realistic three-dimensional images of the object's surface.
