The ultraviolet radiation level is not a variable controlled by bioreactors in order to produce large amounts of microbes

A bioreactor is a vessel or tank designed to generate a suitable environment under controlled conditions (e.g., nutrients, pH, etc) for enzymes, microorganisms or animal/plant cells that convert biochemicals into products.  

For example, bioreactors are used in the biotechnology industry to produce different components such as beneficial microorganisms, pharmaceuticals, vaccines, and antibodies.

Bioreactors can also be used for sterilization procedures (for example, in water treatment.

who created the earth

Answers

God, He is the one that created the earth.

Explanation:

Hey, there!

It's not obvious that who created the Earth.

Noone can say the answer of who created Earth because Earth wasn't created by any human or any specific creatures.. So, let me give some information about creation of Earth. Many hypothesis has been given by our great astronomers and philosophers. Here, i'm gonna describe some:

Old planetesimal hypothesis: According to this hypothesis there was a huge gaseous mass and comet collided together as a result, a very large amount of matter was thrown out of the sun, which later on cooled and planets are formed.Nebular hypothesis: According to this hypothesis the sun, the earth and other planets were formed by a large whirling cloud of hot gases and dust. When the cloud cooled and grew smaller, it began to spin faster. As the surface of the cloud cooled by radiation, a ring a matter was formed at the equatorial region of it.New plantesimal hypothesis: According to this hypothesis, the gaseous mass didn't collied with comet but they came closer to one another and due to gravity of comet, great tidal rose on gaseous mass. The materials rise up as a large spiral arms. Then the spiral arms were cooled down and broke away from the main mass. Then they were considered to be planets and main mass as the sun. It is modern of old plantesimal hypothesis. Tidal hypothesis: According to this hypothesis, it was also supposed that a comet passed through and had exerted a tidal pull upon a mass. The outer part of the filament escaped into space, inner part came back into the gaseous mass and middle part formed different sizes, which were planets and remaining were sun.Dust-cloud hypothesis: This hypothesis is different tgan above. It says tgat all planets were formed by large cloud of dust and gases. The light of stars pushed the atoms of gases and dust to form a large particals. These particals were attracted to eachother by gravity and began to crowd together. Eventually, a huge ball of materials formed the sun and the solar enegry was produced by nuclear reaction. Other particals remain near the sun and started revolving around it. The huge whirlpools originated in the rotating clouds which formed the smaller gaseous glodsand dust to form planets.

This is how the earth was originated or created according to different hypothesis. so, there is no any single people or things that created the earth.

Next the student drops candy tablets into the drink using a rolled piece of paper, so that the tablets are able to fall into the drink continuously. The student notices a very powerful reaction as the drink fizzes and starts to bubble In this scenario, what would be the catalyst ? O The candy tablets being added to the drink The gasses being released when the drink was first opened The piece of paper being placed over the soft drink O The container that holds the liquid​

Answers

Answer: the candy tablets being added

Explanation:

just took it

The candy tablets being added to the drink would be the catalyst of the reaction in the drink.

WHAT IS A CATALYST:

A catalyst is any substance that makes the rate of a chemical reaction faster by lowering the activation energy needed for the reaction to occur.

Catalyst makes a reaction proceed faster than usual. In this case, a student who wants to make a liquid volcano notices bubbling in a sealed drink bottle. She then opens it and began to add candy tablets using a rolled piece of paper.

She notices that a very powerful reaction occured as she constantly puts the candy tablets in the drink. This suggests that the catalyst of this reaction in the drink is the CANDY TABLETS.

the frequency of a drum note is 20Hz. what does this tell you about the drum skin movement

Answers

Answer:

The drum skin oscillates 20 times per second

Explanation:

The frequency of a note is dependent on the mechanical activities that occur when it is produced. A drum is beaten in this case. The oscillation of the drum skin transfers sound waves to the air particles which move at the same frequency before reaching our ears.

If the frequency of the sound wave is 20 Hz this means that the wave is oscillating 20 times in one second. For the drum to produce such a sound, the skin must have been oscillating at the same frequency of 20 oscillations per second too.
