Astronomical units
Which of the following is a starting compound during cellular respiration?
glucose
Which of the following gases is formed during photosynthesis?
Oxygen
What type of galaxy is most common?
Spiral
Which statement is correct about the total mass of glucose formed during photosynthesis
It is less than the total mass of carbon dioxide and water light used.
Which of the following waves have the longest wavelengths?
Radio waves
In which of the following forms is carbon present in the atmosphere?
Carbon dioxide
Ken wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. Step 1 is missing.Step 1:Step 2: Plants use carbon dioxide to make glucoseStep 3: Plant-eating animals consume the glucose present in plantsStep 4: Animals exhale carbon dioxide
Carbon enters the atmosphere as carbon dioxide from respiration and combustion.
Which process takes place in both plant and animal cells?
Cellular respiration
What type of energy transformation takes place when carbon is cycled as animals sweat from movement?
Chemical energy to thermal energy
Which of the following terms best describes a group of galaxies?
Cluster
Which of the following terms best describes a group of thousand galaxies?
Cluster
Which of the following processes would impact the cycling of carbon between land and air?
Deforestation
Which of the following stars usually shine with the dimmest of light?
Dwarfs
Which of the following is an example of how science can solve social problems?
It can identify the sources of polluted water.
Which of the following statements best explains how the high-gain antenna in Voyager probes has made outer space exploration easier?
It can send data to Earth.
What happens to the glucose molecule during the process of cellular respiration?
It gets broken down.
Which of the following statements best explains how the photopolarimeter has made outer space exploration easier?
It is able to determine the properties and composition of planets.
The balanced equation for photosynthesis is shown below.6 CO2 + 6 H2O → C6H12O6 + 6 O2
It is conserved because the total number of O atoms on each side is 18.
During which of the following processes would carbon most likely be required?
Making of glucose
Which of the following processes releases carbon into the air?
Respiration
Which of the following best describes an elliptical galaxy?
Several billion stars arranged in a smooth flat manner
Which of the following processes is not a part of cellular respiration?
Simple sugars are formed.
Which feature of the sun is caused due to an eruption of high-energy radiation?
Solar flare
Which of the following measurements is used to measure the distance between astronomical bodies?
Speed of light
Pam described two substances which participate in photosynthesis.Substance A: Combines with carbon dioxide to form sugarSubstance B: Traps sunlight in green plants
Substance A is water and Substance B is chlorophyll.
Which of the following substances is formed during photosynthesis?
Sugar
Which of the following stars is likely to be the dimmest?
The least massive star
Which of the following stars is likely to be the coldest?
The red-colored star
Which of the following is true about the products formed during photosynthesis?
They have the same mass as the mass of reactants.
During cellular respiration, which of the following is equal to the total number of oxygen atoms in glucose and oxygen gas?
Total number of oxygen atoms in carbon dioxide and water
Hugh wrote the characteristics of two types of galaxies as shown below:Type A: Has a central core from which curved arms come outType B: Forms a perfect sphere or a smooth flattened oval
Type A is a spiral galaxy and Type B is an elliptical galaxy.
Which of the following is composed of about one hundred billion galaxies?
Universe
