Answer:
Actually, the ELECTRON: Negatively charged particles in an atom. Electrons, which spin around the protons and neutrons that make up the atom's nucleus, are essential to chemical bonding.
Explanation:
Answer:
b. to amplify the signal
Explanation:
A multi-enzyme phosphorylation cascade is a series of signaling events where one enzyme phosphorylates to another, then this last enzyme acts to phosphorylate another protein and so successively, thereby triggering a chain reaction that leads to the phosphorylation of hundreds or even thousands of proteins. A multi-enzyme phosphorylation cascade is known to increase the number of activated (phosphorylated) proteins at each step of the signaling cascade. Phosphorylation is a posttranslational modification capable of activating proteins during long periods, thereby a phosphorylation cascade also enables the activation of multiple proteins before these proteins become inactive again.
Answer:
The correct answer is - a. mesial, b. distal c. buccal d. distal e. lingual f. occlusal.
Explanation:
Mesial is the surface near the midline of the face, In dentistry, the canine is mesial to the first molar which means it is the middle of the face. The third molar is distal to the second molar.
Distal is the backside of a particular tooth in dentistry. The cheek side of the tooth known as the facial surface for the front teeth in dentistry. Lateral incisors are distal to the central incisors. Lingual is the part of the tooth near the tongue. The chewing surface of posterior teeth is also known as the occlusal.
Answer:
The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.
Explanation:
Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.
The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.
The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.
In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.
