The aspect of his experimental process that is most important for obtaining reliable results is : Taking observations at precise intervals.

With this, Cameron will not messed up the duration data during each stage of germination.

hope this helps

An experiment signifies a method done to support, refute, or validate a hypothesis. The experiments provide insight into the cause and effect by showing that what outcome is possible when a particular element is changed.

In the given case, the most important characteristics of the experimental approach is to attain reliable results by noting observations at the fixed intervals. With the assistance of this, Cameron will not be confused with the time-period of data at the time of each phase of germination.

If Cas9 edits DNA, why is a molecule of RNA needed in a CRISPR complex?
pantera1 [17]

Explanation:

The use of CRISPR/Cas9 avoids the need for protein engineering to develop a site-specific nuclease against a specific DNA target sequence, requiring only the synthesis of a new piece of RNA. This dramatically simplifies and greatly reduces the time needed for gene editing design and implementation.

Which of the following correctly pairs biotic factors with an effect on the biosphere?
uysha [10]

The statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.

<h3>What are biotic factors?</h3>

Biotic factors of an ecosystem refers to the living components of that ecosystem. Biotic factors include the following:

  • Plants
  • Microbes
  • Animals

Biotic factors make use of oxygen in the atmosphere to perform the process of respiration, hence, their presence will cause a decrease in the oxygen content.

Therefore, the statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.
