The cardiovascular system
The cardiovascular system is an
organ system which allows blood to circulate and transports nutrients, gases, hormones,
and blood cells within the cells of the body for proper functioning of human
cells and organs. The cardiovascular system is made up of the heart and the
circulatory system. A group of arteries, arterioles, and capillaries help to carry
blood from the heart to other parts of the body.

Scientists can reduce uncertainty by performing repeated hypothesis testing trough experiments or observations that exhibit the same predictive outcomes.
<h3>What is hypothesis testing?</h3>
The expression 'hypothesis testing' makes reference to experimental and also observational methods used to test (either confirm or reject) a scientific hypothesis.
Hypothesis testing helps to reduce the level of uncertainty because the same results in different outcomes represent an excellent a measure of reliability by means of the scientific method.
In conclusion, scientists can reduce uncertainty by performing repeated hypothesis testing trough experiments or observations that exhibit the same predictive outcomes.

Answer:
Metabolism refers to chemical reactions that occur within the cells of living organisms -that involve the interaction of substrates, co-factors and enzymes to obtain a product- while homeostasis refers to the internal balance within the body.
Explanation:
<u>Metabolism</u> involves a series of processes that occur in order to obtain a result or product necessary for life. Exist chemical reactions that are part of various metabolic pathways, where chemical substances are transformed into others through the intervention of specific substrates and enzymes. In metabolism reactions can be
:
- Anabolic, when necessary molecules are constructed or synthesized, such as the biosynthesis of proteins from amino acids
- Catabolic, when a substrate is broken down to obtain a product, such as glucose to produce energy (ATP)
.
<u>
</u><u>Homeostasis</u><u> </u>is the maintenance of the proportion of elements for the body to function properly. It is the equivalent of internal balance, which makes use of internal regulation mechanisms.
<em>
A correct functioning of the metabolic reactions guarantees an adequate homeostasis, and the balance that is required for the organism to function properly, implies a regulation of the metabolic processes that occur.</em>
