Answer:
Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide. Oxygen and carbon dioxide, therefore, are involved in both respiration and metabolism. Metabolic reactions are sometimes referred to as cellular respiration, which can cause confusion.
Answer:
New species can appear gradually through small changes in an ancestral species.
Explanation:
The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.

Explanation:
2. Organism are classified foe easy identification.
3.classification of living things includes 7 levels:
kingdom
Phylum
Classes,
Order
Families
Genus
Species .
4.Organisms are classified into domains according to their characteristics features,habitat and mode of nutrition/ adaptation.
5.These organisms are classified together because they are made up of eukaryotic cells. Characteristics like structure, function, and method of reproduction further classify the organisms into smaller groups called kingdoms. The three domains are further divided into six Kingdoms.
6.Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.
A single base-pair deletion would cause a frameshift mutation, disrupting every codon sequence read after it. A single base-pair change, however, only affects one codon. It is therefore less likely to cause harm.
