Answer: B. The number of individuals that a habitat can sustain with the resources that it has available.
Explanation:
A carrying capacity is the number of individuals of the population belonging to a particular species that an habitat or region or ecosystem can support or sustain in terms of providing the resources. If the population exceeds over the carrying capacity then this results in decline in members of the population.
According to the above description the accurate definition of carrying capacity is B.
Scientists will look for evidence like similar body or skeleton structures, internal similarities or maybe sometimes the whole heirarchy to confirm that two speices are closely related to each other.
For example ; in birds, scientists will look for type of feathers, body structure, beaks to confirm the similarity of two birds.
Out of the following given choices;
contain ribose
consist of two strands
made of nucleotides
have an R group
The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.
