Answer:
A species refers to the group of similar organisms that can interbreed to produce a viable offspring. For example, <em>Homo sapiens </em>is a species of humans, <em>Panthera leo </em>refers to the species of lions et cetera.
In contrast, a population in ecology refers to the group of organisms of the same species living in a particular area. For example, the deer population in a forest, human population in a town et cetera.
For example, <em>Aptenodytes patagonicus </em>refers to a species of penguins but number of penguins of the same species living in a particular area would make up a penguin population of that area.
Answer:

Answer: Option C) Root hairs have an elongated shape that increases the surface area-to-volume ratio.
Explanation:

Excretion is the only effective way invertebrates fight disease. Because they don't have an immune system working daily, invertebrates only have the capacity to excrete and cleanse their body of harmful materials.
