Answer:
infection control- clean equipment to prevent spread of germs
All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation
Everything needs to be sterile
All instruments need to be inspected for any signs of contamination after the sterilisation process
Shoes from outside should never be worn inside an operating room
Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment
The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids

How would the fact that a species like the Florida panther "requires large territories" make it vulnerable to extinction?
Answer:
Continued human development and natural resource abuse lessen the amount of wilderness, affecting the Florida panther particularly negatively due to its requirement for large territories.
Answer:
With the continuous expantion of humanity and society, wild territory is becoming smaller and smaller. The more needs an animal requires, the harder it will be for that animal to survive.

I would like to note that I am dissatisfied with the answer you gave nineteen different questions (including my own); And I quote "Sorry don’t know just trying to get points". These are the words that were used, and it is impossible for me to believe that you would be jumping up and down for joy if this was the answer you got on your questions. Now, I could have done the same to you for revenge (trust me, the thought passed my mind), or, I could show you what it is like to act mature. Again, I feel sorry that you fill your days with letting others down when they need it. I hope my answer helps you more than your answer helped me.
And to any other people who may see this answer, if you do the same thing as this user, please stop. It makes others feel like they don't mean anything to anybody else. This behavior is not a habit, it's a disease. It makes me incredibly upset, so please stop the unnecessary fake apologies.

Explain what happens to a cell as it enters the cell cycle and goes through the process of
MITOSIS. Tell what happens to the cell at each part of the cell cycle starting at
Interphase, then the stages of Mitosis (PMAT) and ending at Cytokinesis. (This should be
a longer response than one sentence!!)
Answer:
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

Answer:
Cause: Earth’s magnetosphere traps radioactive solar wind particles in bands around Earth → Space travel through the Van Allen belts is dangerous.
Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.
Cause: Solar wind particles interact with Earth’s upper atmosphere → Effect: An aurora is created
Explanation:
I have been able to drag the tiles to the correct boxes to complete the pairs.
When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind. The solar wind are captured by and held around a planet by that planet's magnetic field.
When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.
Answer:
Cause: Earth’s magnetosphere traps radioactive
solar wind particles in bands around Earth.
Effect: Space travel through the Van Allen
belts is dangerous.
Cause: Earth is surrounded by a magnetic field.
Effect: Solar wind deflects toward the poles.
Cause: Solar wind particles interact with Earth’s

1. A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
2. Coral snakes are brightly colored, highly venomous snakes with red, yellow, and black bands along their bodies. Another species of snake, called the scarlet king snake, has similar bands of red, black, and yellow. Which of the following describes the conditions that resulted in a large population of king snakes with these types of markings?
King snakes and coral snakes relied on similar food sources that contributed to their unique coloring.
Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.
Coral snakes mated with king snakes often enough to produce another species of king snake with the red, black, and yellow.
Overproduction of offspring increased the likelihood that the genetic mutation leading to these bands would spontaneously occur.

Imagine that a space shuttle carrying astronauts is launched from Earth to the International Space Station (ISS). As the shuttle travels toward the ISS, it will encounter different layers of Earth’s atmosphere.
helppppppppppppp Determine the change in temperature that the shuttle will experience while passing through each atmospheric layer.
temperature decreases with altitude
temperature increases with altitude
Answer:
Troposphere - temperature decreases with altitude
Stratosphere - temperature increases with altitude
Mesosphere - temperature decreases with altitude
Thermosphere - temperature increases with altitude
Here's a visual to to the changes in temperature as altitude increases:
how many layers are in earth atmosphere ?
The Earth’s atmosphere is layered and each layer of the atmosphere has its own specific traits. The atmosphere of Earth is divided into four layers as Troposphere, Stratosphere, Mesosphere and Thermosphere
Generally, temperatures decrease with increasing height because the atmosphere distributes itself according to gravity. In the troposphere, the temperature generally decreases with altitude. The reason is the troposphere's gases absorb very little of the incoming solar radiation.
Troposphere - temperature decreases with altitude
Mesosphere - temperature decreases with altitude
The temperature increases with increasing altitude in the stratosphere because there’s a high concentration of ozone molecules.
Stratosphere - temperature increases with altitude
Thermosphere - temperature increases with altitude

What would happen if we didn't have a moon?
Answer:
The moon affects the angle of the Earth's tilt. ... The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Explanation:
Answer:
Simply said: Night would be a lot darker
Explanation:
The moon is responsible for a lot of things, but two that it's most well-known for is the pull is performs on the earth and lighting the sky at night. The moon reflects light from the sun, allowing us to see better at night, without assistance from outside sources- so simply said, it would be a lot harder to see. Also, the moon pulls the earth towards it, which causes more stability for the planet. A side effect of this are tidal waves.
