<h3>What is an organism?</h3>
An organism is a living entity that is defined by the presence of cells, which are the basic structural unit of life.
Organisms have the ability to respond to external stimuli, perform metabolic activities and exhibit a internal state of equilibrium (homeostasis).
Organisms can be composed of single cells (e.g., bacteria, protists) or many cells (e.g., plants and animals).
In conclusion, the Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.

This is called purging. Purging is a situation when a person gets rid of ingested food <em>voluntarily</em>. This is in contrast to vomiting which is often involuntary. Purging is usually manifested by people with eating disorders such as <em>buliumia nervosa</em> and body dysmorphic syndromes.
<em>Starvation is the lack of nutrients due to reduced intake of food and constipation is reduced frequency of defecation associated with difficulty in defecation.</em>
Answer:
hydrogen
Explanation:
the more hydrogen ions then lower the ph and the fewer hydrogen lions the higher the ph.
The immense amount of information stored in DNA is coded with just four base nucleotides. These four nucleotides are paired by twos to form <u>complementary </u>DNA chains.
The makeup of DNA is limited to two <u>pairs </u>of nucleotides bases. One of these pairs is a pyrimidine base whilst the other forms a purine base. The four nucleotides that will make up the entire DNA code are:
- Adenine (A)
- Guanine (G)
- Cytosine (C)
- Thymine (T).
A and G will pair to form the purine base, meanwhile, Cytosine pairs with Thymine to form the <em>pyrimidine base</em>. As per the entire DNA code, A will always pair with G.
Whilst C always pairs with T. This is due to the very nature of the nucleotides themselves and will not change throughout the synthesis or duplication of DNA. Therefore, to complete the complementary strand described in the assignment we must match the letter given with its corresponding base pair, using this rule of DNA.
