Answer:
Negative feedback occurs when a system's output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body's homeostasis.
When you expect something, but get something else, you have a reason big enough to ask new questions and start a new investigation.
Example:
If you create a tree by artificially breeding different species, and then plant it with certain expectations in width, size, bark width, leaf shape, etc. and things go differently, a new investigation might begin with a whole new load of questions.
Answer:

Hope it helped,
Happy homewok/ study/ exam!
Agree
Explanation:
It is very correct that plants cannot walk and animals can't use energy from the sun.
Locomotion is the movement of body from one place to another.
The process by which plants manufacture their food using sunlight is called photosynthesis.
- Plants are fixed, sessile and cannot move about.
- Their root penetrate deep into the earth by which they derive their own nourishment.
- Walking is one attribute of higher animals.
- Manufacturing of food using sunlight is in the exclusive preserve of plants.

A body of underground water, usually comprised of water saturated regolith, is permeable, and replenishes lakes and streams, is known as a aquifer.
Groundwater to be able to get into a rock with good porosity it must also have good permeability. For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.
An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers confined and unconfined.
