Answer:

<em>Evolution</em>

Explanation:

Evolution can be described as the changes which occur in a population over a period of time. Over a period of time, organisms tend to evolve those characteristics which make them better adapted to live in an environment. Such changes which occur over a long period of time are termed as evolution. Charles Darwin was the scientist to bring forward the theory of evolution.

The change in the tail length of a rat over a course of many years is an example of evolution.

Alexxandr [17]

Answer:

soil and vegetative matter screening for soil structure integrity and invasive pathogens

Explanation:

Repeated use of fertilizer causes the soil to break down and lose it nutrient capacity. This in turn will affect the integrity of the plants, now in a nutrient deficit environment. In addition to this, soil micro-biome environment may also be compromised once soil structure and nutrient is lost. Some of the bacteria, fungi and protozoan in the soil plays a role in defense against invasive pathogens. When this is lost the possibility for infection and increased risk of unknown pest and disease is imminent.

Covalent bonds have a higher melting points than ionic bonds.<br><br> True<br> False
melomori [17]

Answer:

This statement is false.

Explanation:

Ionic bonds have relatively high melting and boiling points, compared to that of covalent bonds.

Ionic compounds have strong electrostatic bonds between oppositely charged ions. Covalent bonds, on the other hand, have weaker attractions between molecules.

Remember, the melting point, is simply the amount of heat (energy) it takes to break apart the molecular bonds. The stronger the bonds, the harder it will be to separate them!

Hope this helps! :)

Negative feedback
zhuklara [117]

Answer:

b. Works within an upper and lower range

c. " Is regulatory. "

d. Is very common in biological systems

Explanation:

Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.

For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
