In scientific investigations, how does empirical evidence help scientists devise hypotheses?
nika2105 [10]

Answer:

Explanation:

An empirical evidence illustrates facts that are drawn from experimentation and observations. These are usually drawn from the way we see and percieve our environment using our senses.

A hypothesis is best and simply defined as a scientific guess. It is often a direct product of empirical studies of a particular problem. Most times when scientists gather facts and principles have been formulated, they try to explain their observation. This explanation is the hypothesis. The satement of the hypothesis is usually tentantive. Sometimes, we can have several hypothesis for a common source of empirical evidence.

inn [45]

All macromolecules have carbon atom and the hydrogen atom.

<h3>What are macromolecules?</h3>

The term macromolecules refers to the molecules that are composed of smaller units. These smaller units are called monomers. The macromolecules that we are concerned with here are the macromolecules that could be found in the human body.

The biological macromolecules are often very large as we can see. This is because the number of units that are joined to form the macromolecules are usually very much. There are thousands of monomer molecules that are joined together to give proteins, lipids, carbohydrates and the nucleic acid macromolecules.

All the macromolecules have the carbon atom and the hydrogen atom. These are found across all the macromolecules. The carbohydrates are reducing sugars thus they contain the carbonyl bond. The carbonyl group is absent in lipids, nucleic acids, proteins, and amino hence they do not undergo carbonyl reduction reactions.

Do Decomposers use carbon to make food molecules
babunello [35]

Answer: it releases it

Cellular respiration is done by decomposers to provide energy for themselves, and the molecules of the object the decomposers eat goes through cellular respiration. Eventually, the molecules from the object are released as CO2 and H2O because of cellular respiration, and CO2 and H2O are used in photosynthesis.

Hope this helps you:)
