Vera_Pavlovna [14]

Answer:

<u>The process of photosynthesis occurs in the chloroplast</u>. Photosynthesis can be described as a process in which plants convert water and carbon dioxide into glucose and oxygen. Oxygen is the by-product of the reaction. The energy for this reaction is taken by the chloroplast by trapping light energy of the Sun.

The reaction for photosynthesis can be written as:

6CO2 + 6H2O → C6H12O6 + 6O2

<u>The process of cellular respiration takes place in the mitochondria.</u> Respiration can be described as a process in which glucose and oxygen get converted into carbon dioxide and water. Energy is released by this process which is used for many cellular activities. Hence, mitochondria is known as the powerhouse of a cell.

The reaction of cellular respiration can be summed up as:

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP

Both, these processes provide energy for the working of cells.

Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits. Mars
Mars Close Approach to Earth

Simply go outside and look up and, depending on your local weather and lighting conditions, you should be able to see Mars. That is the point in Mars' orbit when it comes closest to Earth, this time at about 38.6 million miles (62.07 million kilometers) from our planet. 24.8 million miles
Venus is closest to Earth at its inferior conjunction. The smallest distance this can be today is just under 24.8 million miles (40 million km). Their orbits rarely make this happen, but there is such a close approach in January 2022. Also, The Moon
A huge system of stars is called a galaxy. The Moon is the closest celestial body to our Earth. Earth is the third nearest planet to the Sun. Planets do not have their own heat and light.

How can food handlers avoid time temperature abuse?
Andru [333]

Make sure food is not left out for an excessive amount of time as this could cause it to enter the danger zone for temperature and allow bacteria to grow. To stay out of the temperature danger zone in the kitchen, make sure your refrigerators and freezers are set to the proper temperature.

<h3>Food is what?</h3>
  • Any material consumed as food provides nutrition for an organism.
  • Food comprises essential nutrients such carbohydrates, lipids, proteins, vitamins, and minerals and is frequently generated from plants, animals, or fungi.
  • An organism consumes the substance, which is then absorbed by its cells to provide energy, support life, or stimulate growth.
<h3>What is temperature?</h3>
  • Temperature is a physical quantity that expresses how hot matter is, or as a measure of the average translational kinetic energy per atom or molecule in the system.
  • It is the detectable portion of the molar thermal energy of matter; a temperature difference allows heat transfer to occur, as energy flows from a hotter body to a colder body.
