Answer: A. reporting results of scientific analysis.

A physical evidence, also called real evidence. It is a tangiable evidence, which can be touched, picked and collected from the scene of crime or any other place. It can be used to prove a crime has occurred. Physical evidences includes fingerprints, footprints, fibers, paint and building materials.

A specimen sample is taken from the suspects or victims and compared with suspected samples obtained from the scene of crime. The comparitive analysis of physical evidences can be used as a scientific evidence against criminal.

Therefore, reporting results of the scientific analysis is the task she should perform.

schepotkina [342]
The answer is 44 chickens and 28 rabbits.

We have a system of two equations.
x - the number of rabbits
y - the number of chickens

Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.

Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.

Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.

Diffusing molecules move ________ until they are ________. Through channels of active transport proteins; evenly distributed up
koban [17]

Answer;

-Down the concentration gradients; evenly distributed

Diffusing molecules move down the concentration gradients until they are evenly distributed.

Explanation;

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
