Answer:
Explanation:
cells, tissues, organ, and body system.
The phrase survival of the fittest can be misleading because survival of the fittest means the more fit you are the better chance you have at survival but if you're in the wild and use smarts like setting traps you can over power the other animals same thing with humans we are not the strongest animal on the planet but we evolved to have brains that are smart enough to process info so that we could adapt to our environments.
Think of it this way: the energy from that sunlight, plant and/or animal, is going into the predator's mouth.
The hypothesis by Coleman was that the product of the ob+ gene was the appetite suppressing hormone. Hence, the homozygous ob/ob mutant are in a position to synthesize that hormone, and its circulating level would be zero. He also hypothesized that the product of the db+ gene was the receptor for the appetite-suppressing hormone. Thus, the homozygous db/db mutant would be able to synthesize the hormone but would not be in a position to respond to it. It would eat excessively and produce large amounts of body fat, which in turn would produce large amounts of appetite-suppressing hormone . In the absence of a receptor, the db/db mutant's hormone level would remain abnormally high.
Coleman's hypothesis were confirmed when the precise functions of the ob+ and db+ genes were determined. The peptide hormone encoded by the ob+ gene was named Leptin.
Answer:
Roots---xylem vessel-- upper parts of plant.
Explanation:
The plant absorb water from hairs present on the roots and taken this water to the xylem vessel that is responsible for transporting water to all parts of the plant body. Water enters in the root through a process is called osmosis until it reached to the xylem vessel. Osmosis is a movement of molecules through a semi-permeable membrane into a region of higher solute concentration in order to equalize the solute concentration.
