Actually energy is the capacity to do work. It is not moving. It is transmitted, propagated, dissippated, or radiated. It depends upon what type of energy it is. Heat energy is dissippated through conduction, convection or radiation. For conduction the particles must be in contact. For convection the particles which posses the energy must ba able to move about. For radiation, even without a material medium the energy is transmitted in the form of waves. Eg. energy from the sun. When a stone is dropped in still water the energy is imparted to the water surface. This energy is distributed all over the water surface in the form of circular waves (ripples). Electrical energy - through conducting wires or electromagnetic radiation. Light energy & sound energy are through waves.

MRSA has emerged as a serious infectious disease, with the first case of methicillin-resistant S. aureus being detected in 1961.

andreev551 [17]

Answer:

All of the options are true for a MRSA infection.

Explanation:

Staphylococcus aureus is one of the most frequent pathogens causing hospital and community infections. S. aureus can become very easy methicillin resistant (called MRSA isolates) and others beta-lactam antibiotics (are the ones widely used to treat infections) and usually can be resistant to other class of antibiotics, become a very strong bacteria making treatment options very limited. MRSA isolates can rapidly transfer the methicillin resistance to other species of Staphylococcus and some other bacteria. Also S. aureus can acquire other antibiotic resistant genes making a deadly bacterium for its strong resistance. It is in search how the bacterium acquire this antibiotics resistance ( and other virulence factors genes) and the mechanism involve to develop new drugs to treat MRSA infections with the hope that can´t develop resistance to this new drugs.

Which of the following chemicals opens us binding sites allowing muscle filaments to connect to each other? Select one:

HACTEHA [7]

Answer:

The correct answer will be option-D.

Explanation:

Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.

Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.

This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.

Thus, option-D is the correct answer.

An ion can be removed from an aqueous solution by 1. the formation of a gas that escapes. 2. formation of a precipitate. 3. the

Lena [83]

The correct option is ALL OF THESE.
Generally, three processes can lead to the removal of ions from solutions, these include;
1. The formation of an insoluble product, which is called precipitate.
2. The formation of either a non electrolyte or a weak electrolyte and
3. The formation of a gas product, which escapes from the solution.

Which best describes the purpose of a controlled experiment?

leva [86]

I think the correct answer from the choices listed above is option C. The purpose of a controlled experiment is to examine whether one variable causes a change in another. An independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect.
