Acetylcholine, sometimes shortened to ACh.
C. The cell's ability to feed enough
Answer: High Frequency waves by method of compression bone conduction
Explanation: in this, vibration of the bones of the skull and sometimes, arguably soft tissues leads to the production of sounds. The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
Greater genetic diversity, compared to asexual reproduction.
If you think about it, this makes sense because in asexual reproduction, an organism reproduces all by itself, and uses its own genome as the blueprint for its' offspring. However with sexual reproduction, two organisms come together, each contributing half the required chromosomes, and the offspring gets 1/2 it's genes from the mother and 1/2 it's genes from the father. Sexual reproduction allows for greater diversity because it doesn't just rely on mutations to add new diversity to the genepool.
Answer:
In order to control invasive species, we have implemented chemical controls such as pesticides, herbicides, and fungicides.
