What is the most important reason to control the conditions of an experiment?
O to make the experiment easier to repeat
O to reduce the amount of data that must be recorded
O because this is necessary for graphing the data
O because this is necessary for the data to be valid

Answers

Answer 1

Answer:

The answer would be the last choice, "because this is necessary for the data to be valid."

Explanation:

This is because in an experiment, things must be controlled or monitored in most ways; otherwise, the result of the experiment will be different from what it was meant to be. An experiment should be as exact as possible. If this is not possible, results may be unreliable.

B. Cellular respiration produces carbon dioxide from glucose made by the process of
photosynthesis.

C. Photosynthesis produces carbon dioxide from ATP made by the process of cellular
respiration

D. Cellular respiration produces carbon dioxide from ATP made by the process of
photosynthesis.

Answers

Answer:

B. Cellular respiration produces carbon dioxide from glucose made by the process of

photosynthesis.

Explanation:

Photosynthesis is a process by which the autotrophic cells make food by absorbing and converting solar energy into chemical energy.

Cellular respiration is a process in which the oxygen molecules couple with food nutrients to generate energy, CO₂ and water.

The correct answer is:

Option B. Cellular respiration produces carbon dioxide from glucose made by the process of photosynthesis.

This can be explained as:

Photosynthesis uses the light energy from the sun to convert them into chemical energy.

The reactants of photosynthesis are sunlight, carbon dioxide and water molecules and the products produced are glucose and oxygen molecules.

The glucose produced by the process of photosynthesis is then utilized in cellular respiration to produce carbon dioxide.

Therefore, cellular respiration utilizes the glucose produced from photosynthesis.

Answers

Answer:

This question is incomplete as it does not contain any provided information. The information is as follows:

Number of cells: Unicellular

Cell type: Prokaryotic

Location found: Underwater volcano

The answer is Archaea

Explanation:

Living organisms has been classified into a large group of three called DOMAIN consisting of Bacteria, Eukarya and Archaea. The major basis of this classification is the possession or not of a membrane-bound nucleus.

Domains Bacteria and Archaea do not possess a membrane-bound nucleus and hence, are PROKARYOTIC. However, in addition to being prokaryotic, Domain Archaea members are unicellular (single-celled) and are found in locations with harsh environmental conditions e.g volcano.

Therefore, an organism with a PROKARYOTIC cell type, UNICELLULAR number of cells and found in an UNDERWATER VOLCANO will belong to the domain ARCHAEA.

Answer:

Trees absorb carbon dioxide from the atmosphere and turn it into oxygen

Explanation:

Trees help to offset our carbon footprint by absorbing carbon dioxide from the atmosphere and turning it into oxygen.

Trees are often regarded as carbon sinks because they take in more carbon dioxide than they release.

The process of photosynthesis is one that allows plants to use carbon dioxide and water in the presence of sunlight to produce their own food. In this process, oxygen is the by-product.
