Answer:
conscious neural control
Explanation:
Neural control of digestive tract is unconscious achieved via the autonomic nervous system.
Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:
• The myenteric plexus – controls digestive tract motility
• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.
Meiosis makes haploid gametes like eggs and sperm cells
In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.
mitosis has 5 different stages: interphase, prophase, metaphase, anaphase and telophase.
the process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase

Answer:
C. habitat isolation; temporal isolation; behavioral isolation; mechanical isolation; gamete isolation.
Explanation:
Reproductive Barriers may be of any type which includes habitat isolation; temporal isolation; behavioral isolation; mechanical isolation; gamete isolation. All these examples are categorized under prezygotic barriers.
Habitat isolation: It occurs in case of allopatric speciation, initially all the members of a species can mate with each other but later on due to geographic barriers like due to a rift, their habitat separates and they cannot mate with each other and later on they evolve as separate species.
Temporal isolation: In temporal isolation, reproductive barrier is different time/season of breeding like American toads and Fowler's toad both are closely related and have potential to mate but due to different mating season they are unable to mate with each other. American toads mate during summers while Fowler's toad mate during late summers.
Behavioral isolation: When the members of two closely related species behave and respond to different mating behavior, it is known as behavioral isolation. For example breeding calls.
Mechanical isolation: Mechanical isolation occurs because of structural or chemical barriers. For example: when the shape of pollinator does not match with that of flower then the male gametes will not be able to reach to the egg cell.
Gamete isolation: When the gametes are unable to fuse due to any reason like less mobility of sperm in the female reproductive tract.
