Answer:There are more species in the tropics because tropical ecosystems have more niches. However, the number of niches in an ecosystem is determined by the number of species in that ecosystem.

Answer:
Polymerase Chain Reaction (PCR)
Explanation:
Polymerase chain reaction (PCR) is a technique that creates thousands of copies of a small amount of DNA. The processes use a small amount of DNA at the template, Taq polymerase as enzyme of DNA replication, primers, and deoxyribonucleotides.
By the end of one round of PCR, two copies of one DNA fragment is formed. These two copies enter the second round of PCR and form a total of four DNA segments. The process goes on and creates the desired number of copies from the single piece of DNA.
Answer:
Sexual Reproduction
Explanation:
Since sexual reproduction automatically causes genetic diversity(crossing over, DNA from both parents, etc.) it produces desirable traits for organisms. Asexual reproduction does not bring in new and desirable traits and is more of a copy of the parent.
Lysosomea are mainly responsible for intracellular digestion and waste removal
