Answer;
All the statements are true of herbivores except that they are sometimes predators.
Explanation;
-Herbivores are animals that gets its energy from eating plants, and only plants. Many herbivores have special digestive systems that let them digest all kinds of plants, including grasses.
-Herbivores form an important link in the food chain because they consume plants in order to digest the carbohydrates photosynthetically produced by a plant. Carnivores in turn consume herbivores for the same reason, while omnivores can obtain their nutrients from either plants or animals.
Answer:
messenger RNA /mRNA!
Explanation:
mRNA is a type of RNA that carries the information about the type of protein to be made
It carries it to the ribosomes for the production of proteins
Ribosomes decode the information on the ribosome and make protein from the amino acid sequence directed by the mRNA
The researcher determines that the S value (number of species at equilibrium) for the island closer to the mainland is higher than the S value for the island located farther from the mainland. In addition, she finds that the closer island's extinction rate is same as the extinction rate on the farther island.
Explanation:
In bio-geographical research of islands, the s-value is the species value of an island ecosystem. This is used to calculate the biodiversity of the island and is dependent on the size of an island and its distance from the mainland.
This is in accordance with the equilibrium theory of island biogeography (ETIB) which states that immigration of species is higher in islands close to mainland and the extinction of species depends on the size of the island; i.e., rate is high in smaller islands and less in larger islands.
In the given case, the researcher is comparing the species value of two islands and concludes that the island near the mainland has a higher species value than the one that is far which correlates with the ETIB theory.
The fact that the extinction rates of the species of both the islands were found to be the same is because both the islands are of the same size, which also correlates with the ETIB theory.
