Why do you think mendel spent so much time observing plants & their offsprings before he began experimenting with them?
I don't know if you mean, like, historically or in relation to the scientific method...
I know he was a monk... (I think it was his job to be the gardener too)
But you're supposed to observe before you can come up with a question that you would then answer through experimentation.

which describes a difference between a positive and negative feedback loop?
a. the output of a system stimulates another cycle of the system only in a positive feedback loop.
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
c. the output of a system maintains conditions around a set point only in a positive feedback loop.
d. the output of a system signals the system to disregard the stimulus only in a negative feedback loop
Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
Explanation:
In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.
Answer:
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Which two changes are caused by shear acting on Earth's crust?
A. The matter in rock gets pulled apart.
B. The matter in rock gets pushed together.
C. Two slabs of rock slide past one another.
D. One slab of rock breaks into two pieces.
Answer: C. Two slabs of rock slide past one another.
Explanation:
Shear stress is one of four stresses that act on the Earth's crust with the other three being Confining, Compression and Tension.
Shear stress is the result of two parallel forces moving in opposing directions to each other. It is the force that results in two slabs of rock sliding past one another.

if we place a dialysis tube filled with water that is a 10% salt solution into a beaker that has a 5% salt solution water will...
A. have net movement OUT of the tube, this is a hypertonic solution compared to inside the tube
B. have net movement into the tube, this is a hypotonic solution compared to inside the tube
C. have net movement OUT of the tube, this is a hypotonic solution compared to inside the tube
D. have no net movement, this is an isotonic solution compared to inside the tube.
Answer:
The correct option is D.
have no net movement, this is an isotonic solution compared to inside the tube.
Explanation:
It will have no net movement, this is an isotonic solution compared to inside the tube because isotonic solution is a solution that has the same osmolarity or solute concentration in both solution, which allow free water movement across the semi permeable memberane on both solution i.e the concentration of the two solution are mostly the same.

A report from the environmental department in one of the universities in the United States gave an estimation of 2.3 million dollars as what is spent yearly to get snow and ice off the streets and highway.
Snow removal is simply an action that is undertaken to get snow off the streets or road after it snowed for safe and easy movement of people.
In conclusion it is estimated to be about $2 billion dollars given 2.3 billion dollars is around this figure.

Explanation:
A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other. The truck parked overnight in a place where energy transferred out of the substance. In the morning, the substance was a gas. How were the molecules moving in the morning?
Answer:
The gases will be together since they do not possess kinetic energy
Explanation:
let us use the kinetic theory of matter to explain the condition of the gas in the morning.
During the day, the atmosphere can be very hot so the gases tend to be in constant random motion, hence they will move away from themselves because they possess kinetic energy.
In the morning the temperature of the atmosphere is relatively low and the vehicle is not in motion, hence the gases will move together because they no longer possess kinetic energy anymore
