Why do most particles in solar wind not reach Earth’s surface?
Inessa [10]

Answer:

Due to the dense atmosphere

The magnetic field of the earth

Explanation:

Most particles in the solar wind do not reach the earth's surface because the atmosphere is very dense and the protecting magnetic field of the earth.

A solar wind is a burst of energetic particles from the sun which are made up electrons, ions, etc.. They travel at a very high velocity.

  • The magnetic field of the earth is able to deflect these charged particles away.
  • In areas such as the pole, the interact with the atmosphere to produce very stunning auroras.

Christmas trees don’t just look pretty, they give out lovely life-giving oxygen. An acre of Christmas trees will provide oxygen
Licemer1 [7]
The answer would be about  18.

<span>Christmas trees give, in fact, a lot of oxygen and in return they consume a lot of carbon dioxide.
</span><span>The oxygen produced by each tree depends on several factors, but there is a estimative. In about 1 acre of land, there are enough trees to produce the oxygen necessary for 18 people to breath during a whole year!

What is the overall reaction for photosynthesis
Leokris [45]
Photosynthesis is a process used by plants and other organisms to convert light energyinto chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις, synthesis, "putting together".[1][2][3] In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth.[4]

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centresthat contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate(NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells.

In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the reverse Krebs cycle, to achieve the same end. In the Calvin cycle, atmospheric carbon dioxide is incorporatedinto already existing organic carbon compounds, such as ribulose bisphosphate(RuBP).[5] Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reducedand removed to form further carbohydrates, such as glucose.

What can you conclude about the susceptibility of the bacteria to the antibiotics?
vova2212 [387]

Susceptibility refers that they can not grow if drug is present . Antibiotic is effective against the bacteria. Resistant means the bacteria can grow even if the drug is present and this sign is an effective antibiotic.

The antibiotic susceptibility testing are based on measuring the inhibition of growth of bacteria. Average time which requires to obtain result are 18- 24 hours for rapid system.Antibiotic sensitivity test can help in finding that which antibiotic is more effective in treating infection accordingly.

Antimicrobial susceptibility test is very significant bacterial isolates and there goal of testing is to detect possible drug resistance in common pathogen to assure susceptibility to drug of choice for particular infections.
