Answer:Negative feedback is a type of regulation in biological systems in which the end product of a process in turn reduces the stimulus of that same process.Sometimes referred to as a “negative feedback loop”, negative feedback occurs when the product of a pathway turns the biochemical pathway off.
Explanation:
<span>A method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.</span>
The correct answer is; <span>You conduct a dihybrid cross. a 12:1:1:4 ratio would make you suspect that the genes are linked. This is the expected phenotypic ratio for the dihybrid cross that would cause the genetic linkage i.e. formation of DNA sequences during the process of sexual reproduction. </span>
Answer:
The producer is some kind of plant
Explanation:
Producers are plants, because plants <em>produce </em>their own food through photosynthesis. Producers obtain their energy from the sun, which they then use in photosynthesis. The equation for photosynthesis is below:
sunlight+water+carbon dioxide⇒oxygen+glucose
<span>The plasma membrane is both a barrier and gateway between the cytoplasm and ECF. It is selectively permeable—it allows some things through, such as nutrients and wastes, but usually prevents other things, such as proteins and phosphates, from entering or leaving the cell.</span><span>The methods of moving substances through the membrane can be classified in two overlapping ways: as passive or active mechanisms and as carrier-mediated or not. Passive mechanisms require no energy (ATP) expenditure by the cell. In most cases, the random molecular motion of the particles themselves provides the necessary energy. Passive mechanisms include filtration, diffusion, and osmosis. Active mechanisms, however, consume ATP. These include active transport and vesicular transport. Carrier-mediated mechanisms use a membrane protein to transport substances from one side of the membrane to the other. We will first consider the mechanisms that are not carrier-mediated (filtration, simple diffusion, and osmosis) and then the carrier-mediated mechanisms (facilitated diffusion and active transport).</span>
