Answer:
A producer is any living organism that makes its own food or makes food for other organisms, for example, plants.
Answer:
D. A base substitution in gametes during meiosis
Explanation:
Sunlight is the source of energy because producers such as grass and trees use photosynthesis to make energy from sunlight. Grass and trees are then eaten by animals like cows, chickens, and pigs. The animal takes in the energy it receives from the foliage, and humans in turn, receive energy from eating the livestock.
Answer:
The classification of organisms as either a prokaryote or a eukaryote is based on the structure of the organism's cell nucleus
Explanation:
The etymology of the word 'karyote' in both 'prokaryote' and 'eukaryote', is derived from a Greek word that explains the nucleus.
An organism having a true nucleus (i.e a nucleus surrounded by a nuclear membrane) in its cell(s), is classified as a eukaryote.
'Eu' in the word 'eukaryote', is derived from a Greek word that means 'true'.
A prokaryote is an organism that lacks a definite nucleus, hence, having its genetic materials suspended freely in the cyoplasm without a special nuclear membrane enclosing it, aside from its plasma membrane.
