Answer:
Option A, Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction
Explanation:
Genetics variation allows as organism to evolve in a way to be able to cope up with the existing or changing environmental condition. Now, a Pantala flavescens undergoes sexual reproduction, thus only this creature has the ability among all the given organism to evolve genetically and be able to survive in this environment. All the remaining organisms reproduce asexually and hence there is no variation with in them and hence it would be difficult for these organisms to cope up with changing environment.
Hence, option A is correct.
Answer:
1. Another word for chemical weathering is b. disintegration
Chemical weathering is a process by which the rocks are broken down into parts and sediments by the action of a chemical agent such as alkali or acid. The disintegration can be a natural process by which a solid body is broken down into parts or subparts.
2. d. moving water is not an agent of chemical weathering agent.
The chemical weathering can be caused by the agents like lichens which secretes acid on the rock surface and causes it's disintegration, acid rain and salt water are chemical agents that can cause the disintegration of the rock but moving water will have little influence on the hard rock surface.
3. c. chemical weathering is a process which turns rocks and minerals into new substances. The chemical weathering process brings change in the chemical composition of the rocks due to the action of the weathering agents hence, on disintegration of rocks new substances are formed.
Mitochondria important for the cell that can't survive without it but blood cell is an exception. Blood is a tissue in animals so RBCs are animal cells and don't have mitochondria
