b. Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases
c. Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits.
d. Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.
2. What can scientists learn about by studying Chemical Isotopes In Foraminifera? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?
3. What can scientists learn about by studying Fossilized Pollen Grains? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?
4. What can scientists learn about by studying Tree Rings? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?
The answer to the questions are :
The scientists learn from the ice cores about the air and other ocean temperatures and also get to know about the Carbon dioxide levels. The scientists studying Foraminifera get to learn about the amount of carbon dioxide in the air. By analysis of the pollen they learn about the changes in vegetation. From the tree rings, they learn about the tress and weather conditions.
Find out more information about the scientists.
Scientists can learn about past air temperatures and carbon dioxide levels from ice cores, past ocean temperatures from chemical isotopes in foraminifera, historical plant types from fossilized pollen grains, and past air temperatures and rainfall from tree ring patterns.
By analyzing different proxies, scientists can deduce valuable information about Earth's past climate and environmental conditions. Here are the specific insights gained from the proxies mentioned:
Geothermal and solar energy both have a mining step, while nuclear energy does not.
b.
Geothermal and solar energy both require water, while nuclear energy does not.
c.
Geothermal and solar energy are both renewable, while nuclear energy is not.
d.
Geothermal and solar energy both generate a significant amount of waste, while nuclear energy does not.
in short the answer is c.
b. Plants perform photosynthesis
c. Plants perform cellular respiration
d. Plants perform both of photosynthesis and cellular respiration
Plants perform both photosynthesis and cellular respiration.
During photosynthesis, the plant converts solar energy into chemical form. Plant captures light that comes directly from the sun and through different ranges of reaction, using its energy to build sugar molecules known as glucose.
Glucose consists of six oxygen atoms, six carbon atoms and twelve hydrogen atoms. When plant produces glucose molecules, it gets the carbon and oxygen it required to make the glucose molecules from carbon dioxide taken from the air.
Although there is no presence of hydrogen in carbon dioxide, therefore the plant uses water to replace hydrogen. The world is surrounded with large volume of water and every water molecules is made of two hydrogen and one oxygen atom.
For the plant to take the hydrogen needed to build molecules, it use the energy obtain from the sun to split the water molecule apart. During photosynthesis, plant consumes carbon dioxide water, and produces oxygen and glucose.
The glucose produced by the plant is important for cellular respiration. During cellular respiration, the presence of chemical energy in the glucose molecules is converted into a form that plant can utilize for reproduction and growth.
The first step of respiration is known as glycolysis, at this step the glucose molecule is broken down into molecules that are smaller also known as pyruvate and a little energy is also released in the form of ATP. The result of cellular respiration in plant is that it consumes oxygen and glucose and produces water, carbon dioxide and ATP energy molecules

KEYWORDS:
The statement that plants perform both photosynthesis and cellular respiration is correct. Photosynthesis is a process used to synthesize food with sunlight and cellular respiration coverts the produced sugar into usable energy.
The correct answer to the question is d. Plants perform both photosynthesis and cellular respiration.Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. Oxygen is a product in this process, not a reactant.Cellular respiration is the process by which cells in plants, animals and other organisms break down sugar and turn it into energy, which is then used to perform work at the cellular level. This process does use oxygen as a reactant to convert the stored sugar into usable energy.
Therefore, plants do both photosynthesis (to make sugar and produce oxygen) and cellular respiration (to break down the sugar into usable energy).
