Ferns make their own food. They grow and reproduce using spores instead of things like seeds. Humans on the other hand have to ingest food from their surrounding and when mature reproduce sexually. They can also choose if they want to reproduce or not while ferns don't have that option. Sexual reproduction is based on inseminating and egg cell, while ferns don't worry about this because the spores just fall on the ground.
Individuals of the same species have different traits because they have different genes which code for different proteins. B would be the correct option.
<h3>Variations</h3>
Organisms of the same species can have different traits due to a difference in their proteins.
Genes are responsible for proteins and proteins are an expression of traits. Thus, with different proteins come different traits.
Hence, once there is a difference in the DNA sequence of organisms, different proteins will be produced, and different traits will be expressed.

The temperature depends to the certain point
Answer:
Endangered
Explanation:
Endangered species are organisms that are at risk of extinction if deliberate efforts are not made to conserve them due to a rapid decrease in their population.
<em>Hence, if a marine biologist writes an article about saving whales and labels them as </em><em>endangered species</em><em>, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem. Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable. </em>
