<h2>Answer:</h2>

While performing any kind of experiment in lab one must be very careful about contamination from other resources.

If you had stored the beaker uncovered for a week, there are 100% chances that your sample will get contaminated either from airborne bacteria in the atmosphere of the lab, other bacteria's from surroundings, or viruses or fungi or any other kind of microbes. If beaker is open there also dust particles that penetrate in it.

So, It is necessary that you should cover your beaker properly with plastic or glass lid or aluminum foil etc while incubation for the smooth results of your experiment.

Talja [164]

Answer:

Embryonic period

Explanation:

The time period of the growth of the baby in the womb of the mother of human is 38 weeks or 9 months.

Which equation best models cellular respiration? (1 point)
jeka94

The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy

CELLULAR RESPIRATION:

  • Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules.

  • Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.

  • The general equation for cellular respiration is as follows:

C6H12O6 + 602 = 6H20 + 6CO2 + Energy

  • Therefore, the equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP).
