Answer:
Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.

Here are some explanations from 0nline so if you want rewrite in your own words
hope this helps :))
blood glucose-
"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."
"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."
body temperature-
" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."
"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."
"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."
"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"
Answer:
It can work against some viruses or bacteria by sweating out the invaders.
Explanation:
The correct options are as follows:
1. D.
<span>A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.
2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.
3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.
4. C.
In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.
5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.</span>
Answer:
What are the advantages and disadvantages of digital over analog?
Do you want to learn more about crypto?
“Advantages of Digital Communication. The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are easy to design and cheaper than analog circuits. The hardware implementation in digital circuits, is more flexible than analog.” In general, digital is far easier to handle and has (virtually) unlimited precision (limited only by hardware constraints and compute time).
Analog computation takes place at a significant portion of the speed of light (the time it takes for an electrical signal to traverse a circuit). However, it is almost impossible to correct completely for noise, and precision is limited to three (or at most four significant digits).
