The subatomic particles of protons and neutrons are found in the nucleus of an atom. Protons are particles with a positive charge, while neutrons have no charge. Electrons, which have a negative charge, are particles that can found orbiting outside the nucleus of an atom.
Difference # Open Store System:
1. There is no specific storage area. Stores are maintained in the form of Suitable/convenient locations.
2. Every individual has access to anystorage facility.
3. After the receipt of the material it is delivered to respective department to expedite the production activity.
4. Chances of Pilferage high.5. Less emphasis on accounting control of the material.
Difference # Closed Store System:
1. All materials are stored in a closed/controlled area.2. No other person than the stores personnel is permitted in the area.
Materials can leave or enter the storage area only by authorised documents.
4. Maximum Physical Security.
5. Tight accounting control of inventory material.
The mechanism of enzymatic action within a single substance
Answer:
The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"
Explanation:
The fruit fly <em>Drosophila melanogaster</em> is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.
Answer:
No, if water is not evaporated, it doesn't affect fishes. Fishes need water for its survival and growth. If water is evaporated from fish tank, the quantity of water is reduced in the tank and fish life is in danger if all water is evaporated. If water is not evaporated from fish tank, it is good for fish growth and development.
