A, cholesterol in the blood
Answer:
C. a sequence of nucleotides in DNA that codes for a functional product.
Explanation:
A gene is referred to as a nucleotide sequence in DNA that codes for the synthesis of a functional product such as an RNA or a protein. It is also referred to as the functional and basic unit of hereditary. A gene is also found on a chromosome and differs from DNA because a DNA just comprises nucleotides and is found in the cell nucleus.
Genes carry genetic information which can be transferred to the offspring from the parents. These genetic information could be the color of the hair, height, color of the eyes and other traits that can be passed from parents to offspring.
Answer:
Habitat
Explanation:
All organisms are in constant interaction with their environment. This includes both biotic, living things, or abiotic, non-living things, factors. Where this interaction takes place is what we call an ecosystem.
Within each ecosystem, e.g. aquatic or terrestrial, <u>a population, or group of species, lives in a specific physical environment known as a habitat</u>, where they occupy their own niches or roles/functions.
Here, several populations of different species can coexist, however, they have their own roles or, in other words, they have specific adaptations to this area. Habitats could range from oceans, lakes, and rivers to deserts, forests, and mountains.
Therefore, a <u>habitat</u> is a physical environment where a species lives and becomes adapted.
