The aperture diameter (distance from side to side) of the opening of the telescope in millimeters. This is the area that lets light in. This telescope has a 18 mm aperture. Telescopes have a limit to how much useful magnification you can get, and this depends on the size of the aperture. Past that limit, and the image begins to break down, so it is not recommended to magnify higher than this amount. In general, the maximum useful magnification is 1.97x for every millimeter of aperture. Based on the size of the telescope’s aperture, what is the maximum useful magnification for this telescope?

Explanation:

Enzymes bring reactants together so they don't have to expend energy moving about until they collide at random. Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the active site

The site on the enzyme at which reactants are brought together during a chemical reaction is known as the active site.

Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being consumed or changed in the overall process. It may be thought that all cellular reactions and processes are mediated by enzymes.

The construction of the enzyme-substrate complex is the first step in the mechanism of enzymatic catalysis. In this step, the reactant molecules are brought together during a chemical reaction. These reactant molecules bind to the active site of an enzyme.

The Active site of an enzyme is the region where substrates bind and catalysis initiates.

Therefore, the active site is the region on the enzyme at which reactants are brought together during a chemical reaction.

Explanation: SOLID SAMPLE :

1. Peel off the skin of any vegetables e.g. potato and fruits as these are often impermeable. Use a clean spatula to remove samples of powdered food. Avoid cross-contamination with other foods.

2. Add a few ( 2-3) drops of bench iodine solution potassium to a piece of solid food on a white tile.

3.Make observations.                                                  

                       LIQUID SAMPLE:

1. Add 10 cm3 of the liquid food sample to a clean, dry test tube.

Explanation:

A nuclear reactor is an installation capable of initiating, maintaining and controlling the chain fission reactions that take place in the reactor core, consisting of the fuel, coolant, control elements, structural materials and moderator in the case of nuclear thermal reactors.

The core is the part of the reactor where the nuclear chain reaction is produced and maintained.

Components of the core:

The fuel of a nuclear reactor is fissionable material.

Control rod beams provide a rapid means of controlling the nuclear reaction, allowing rapid changes in reactor power and eventual shutdown in case of emergency.

The neutrons produced in fission have a high energy in the form of velocity. Their speed should be reduced to increase the probability of other atoms fissioning and not to stop the chain reaction. This is achieved by elastic collisions of the neutrons with the nuclei of the moderator.

Most of the energy released by fission is in the form of heat. To be able to use this, a refrigerant must pass through the interior of the reactor that absorbs and transports this heat.

In a nuclear chain reaction, a certain number of neutrons tend to escape from the region where it is produced. This neutron leakage can be minimized by the existence of a reflecting medium, thus increasing the efficiency of the reactor.

When the reactor is in operation, a large amount of radiation is generated. Protection is needed to isolate the installation workers from radiation caused by fission products. Therefore, a biological shield is placed around the reactor to intercept these emissions.

A breeder reactor is a nuclear reactor that generates more fissile material in the fuel than it consumes. Considered highly attractive because of their superior fuel economy: a normal reactor consumes less than 1% of the natural uranium that starts the fuel cycle, while a 'breeder' can burn it almost completely. It also generates less waste for the same amounts of energy. Breeders can be designed to use thorium, which is more abundant than uranium. Currently, there is renewed interest in both breeder designs due to the increased price of natural uranium.

All commercial reactors breed fuel, but they have low (though still significant) breeding ratios when compared to machines that are traditionally considered breeders. In recent years, the commercial energy industry has been emphasizing high burn fuels, which last longer in the core of the reactor.

Reproduction of fissile fuel is a common feature in reactors, but commercial reactors are not optimized for this feature which is referred to as improved burning. Up to one-third of all electricity produced in the current U.S. reactor inventory comes from reproducible fuel, and the industry is working hard to increase that percentage over time.

The advantages are:

Generates a large amount of electricity

No production of greenhouse gases

Dependence on oil is reduced

Less damage to the environment

A major disadvantage is the difficult management of the nuclear waste generated.

Nuclear power plants have a limited lifetime. The investment for the construction of a nuclear plant is very high.

Answer:

Atoms themselves are composed of three different types of particles—protons, neutrons, and electrons. A proton carries one unit of positive† charge (Dufay's vitreous electricity) and an electron carries one unit of negative charge (Dufay's resinous electricity). A neutron carries no charge; it is neutral.

Not entirely positive but I do know that bioluminescence is a natural substance found in many living creatures and it makes them glow. They could be testing products for ideas of what undiscovered life is on earth. But all I do know is bioluminescence is an ingredient that causes things to glow.

Explanation:

Bioluminescence refers to a living thing that produces and emits light. Glow-in-the-dark animals can be found in all marine ecosystems, including those at the ocean's surface and deepest depths.

Utilizing bioluminescent bacteria, they can swiftly determine the quantity of bacteria present and end the experiment much more quickly, resulting in less pain, a shorter experiment duration, and the usage of fewer animals.

Current applications of the bioluminescence reaction include gene assays, the detection of protein-protein interactions, high-throughput screening (HTS) for drug development, hygienic monitoring, the assessment of environmental contamination, and in vivo imaging of tiny mammals.

Answer:

During the cell cycle, the transition of DNA from its free form to chromosome is beneficial because it allows the equitable division and transmission of genetic information to the daughter cells.

Explanation:

In eukaryotic cells, DNA contains all the genetic information of an individual and is found in the cell nucleus. The way the DNA is found while the cell is in interphase —period without division— is free form, associated with histone proteins, called chromatin.

When cell division occurs, the DNA must replicate and right at the beginning of the division process the chromatin condenses, forming chromosomes. These chromosomes contain the genetic information compartmentalized into genes, making it easier to distribute it equally to each daughter cell.

The main benefit of the condensation of chromatin - nuclear DNA - into chromosomes is to achieve the equitable distribution of genetic information and its transmission to each daughter cell.
