The correct answer is - predator species in a community.
In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.
The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.
If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.
Answer:
At the time in our history when there were slave owners, it was part of our culture to own slaves to help with the labor on farms. It did not make slave owners INHUMAN. It was part of the culture of the times. Maybe not the best part of our culture but was accepted by millions of people and I dont think there were millions of people that were INHUMAN. It was part of our history and we learned from the mistakes of the past. As our culture and society change so do the beliefs and acceptable societal norms. Sometimes for the better sometimes for the worst. Hopefully, most of the time for the better.
Explanation:
Answer:
The correct statements are statement 3 and 4.
Explanation:
An alignment of three nucleotides within the RNA or DNA that assists in coding a specific amino acid or instructs the cell to either cease or begin the synthesis of protein is termed as a codon. A sum of 64 probable codons are found that comprise three of the four possible nucleotides, however, only 20 amino acids are present in the majority of the biological species.
The given third statement is true as there are some of the codons known as stop codons that plays an essential role in terminating the process of protein synthesis.
The given fourth statement is also true as codons known as stop codons are not identified by tRNAs, they are identified by ribosomes.
Answer:
D.
Explanation:
Myeloma cells are fused with cancerous plasma cells to produce hybridoma cells that produce a single type of antibody for the lifetime of the cell.
