skelet666 [1.2K]3 years ago
8 0

Answer:

  1. cell
  2. molecule
  3. macro-molecule
  4. organs
  5. ecosystem
  6. population
  7. population
  8. tissue
  9. organism
  10. Organism
  11. organelle

Explanation:

Level of organisation or biological organisation is defined as a hierarchy of biological structures or systems that contribute to the life.

Level of organisation become complex as it increases in its hierarchy. Arrangement of biological organisation from simplest to complex include : Atom/Molecule/macro-molecules or bio-molecular complex, organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

  • Blood is classified as a cell because it is the basic unit of life.
  • Carbon dioxide  is classified as a molecule because it is made up of group of atoms.
  • Carbohydrates are macro-molecule made up of group of bio molecules.
  • Lungs are the organs which is a functional group of tissues.
  • A desert, including animals, birds, plants, rocks, wind is considered as ecosystem because it include groups of organisms with the physical (abiotic) environment.
  • All species of lizards in a rain-forest tree and Zebras in the zoo are classified as population because groups of organisms of the same species.
  • Skin is considered as tissue because it is a functional groups of cells.
  • One bacterium is considered as a organism because it is a living system consist of single cell.
  • Dog is classified as organism as it is also a living system and made up of several cells.
  • Chloroplast is a n organelle because it is a functional groups of bio-molecules and helps in several chemical processes.

Hence, the correct matches are:

Blood  - cell

Carbon dioxide  - molecule

Carbohydrates  - macro-molecule

Lungs  - organs

A desert, including birds, animals,rocks,  plants, wind  - ecosystem

All species of lizards in a rainforest tree  - population

Zebras in the zoo  - population

Skin  - tissue

One bacterium  - organism

Dog  - organism

Chloroplast  - organelle

Write a 600 word report discussing nuclear reactors. The report should include a description of the way a reactor works and the
barxatty [35]

Answer:

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.
