Answer:
To do this you need to know equation for acceleration: a = Δv / Δt where a is acceleration, Δv is the change in velocity, and Δt is the amount of time it took for that change to occur. The unit for acceleration is meters per second per second or m/s2.

Mr. Carter draws a box with a particle diagram of a liquid on the whiteboard. Next, he draws another box with a particle diagram of a solid, but he leaves this box blank for one of his students to fill in.
What should Mr. Carter's student draw in the blank box?
Answers
Mr. Carter's student must draw particles very close together.
We can arrive at this answer as follows:
Mr. Carter is showing how the particles fit into a solid substance and a liquid substance.In a liquid substance, the particles are separated from each other, which allows the characteristic fluidity of liquids.In a solid substance, the particles are very close to each other, not allowing space between them.In this case, we can say that Mr. Carter's student, when drawing the particles of solid substance, must draw them very close to each other, not allowing any space between them, preventing them from moving.

A cell uses active transport to move sodium ions out of the cell. Why does the cell use active transport instead of diffusion to move sodium ions out of the cell?.
Answers
Answer:
A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.
Explanation:
The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.
WHAT IS ACTIVE TRANSPORT?Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.
This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.

A drug that affects both divisions of the autonomic system is going to bind to, or block, which type of neurotransmitter receptor
Answers
A drug that affects both divisions of the autonomic system is going to bind to, or block the nicotinic neurotransmitter receptor
A chemical that the body produces to interact with those receptors is called an endogenous chemical, whereas a chemical introduced to the system from outside is an exogenous chemical.
Nicotine is not a drug that is used therapeutically, except for smoking cessation. When it is introduced into the body via products, it has broad effects on the autonomic system.
The nicotinic receptor is found on all autonomic ganglia.

Based on this diagram label the positive and negative sides of the DNA fingerprint with a + and – sign.
Answers
We can say that the top of the gel, where the DNA samples were applied, is the negative side, while the bottom of the gel is the positive side.
We can arrive at this answer because:
DNA is a negatively charged molecule.For this reason, when DNA is applied in an electrophoresis vat, it must be placed in the negatively charged portion.This is because the electrophoresis vat will allow an electrical discharge to pass through the vat and drag the DNA from the negative side to the positive side.This movement allows the DNA to present a series of fragments of different sizes that will be observed in a fingerprint, such as the one presented in the question above.
In the figure below you can more accurately see the positive and negative sides.

dna is a double-stranded molecule made up of complementary, antiparallel strands. based on what you know about complementary base pairing, fill in the rest of the details in the figure.
Answers
The details in the figure correspond to the elements that the DNA strands have in their ends. Also, they correspond to the antiparallel strand with the complementary bases.
The DNA has two antiparallel strands with complementary bases (thymine, adenine, guanine, and cytosine). That is to say, that T pairs with A and G with C. Also, they have specific elements in their ends.
The 3' strand in its end has a hydroxyl (OH) group.The 5' strand in its end has a phosphate group.There is a complementary strand with its respective nucleotides that will pair with the other strand according to their specific bases (A-T; C-G)
In conclusion, the top left end of the 3' strand has a hydroxyl group, while the top right, the 5', has a phosphate group. The complementary strand will go the other way round, from 5' to 3', so the hydroxyl and phosphate groups would be on the right and the left, respectively. The bottom strand is the complementary one, and it runs from 3' to 5'.

Why are common cold viruses difficult to cure?(1 point)

The virus leads to other viral infections such as the flu and HIV.
The viral genome mutates very quickly.
Vaccines prevent the development of a cure.
Answers
Answer:
You are very correct the answer is c
Correct option is ''The viral genome mutates very quickly.''
Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.
