The answer would be the second option. The best reason for doing more background research after making an observation and before forming a hypothesis is to prevent making the same mistakes made in a prior experiment. It is to make sure that you are able to see the problems of a research and make an experimental design that will minimize the errors.

2 decided by 5/12 in fraction
Rudiy27

Answer:

\frac{24}{5}

Explanation:

\frac{2}{1} ÷ \frac{5}{12} =

To change the ÷ sign to a × sign, swap the denominators and the numerators of the second fraction.

\frac{2}{1} × \frac{12}{5} = \frac{24}{5}

Directly multiply. Numerators with numerators and denominators with denominators.

Motor (efferent) neurons carry information _____ the brain whereas sensory (afferent) neurons carry information ______ the brain
Norma-Jean [14]
Neurons are the building blocks of the nervous system. They are the links so that information could be processed as electrochemical signals. There are three fundamental kinds of neurons in our body:

1. Motor neurons - they carry signals from the central nervous system (CNS) to the body parts such as muscle movement
2. Sensory neurons -  they carry signals from other body parts to the CNS
3. Interneurons - interlinking neurons between the brain and the spinal cord

Thus, the correct and complete statement above should be

<span><em>Motor (efferent) neurons carry information </em><em>from </em><em>the brain whereas sensory (afferent) neurons carry information</em><em> to</em><em> the brain.</em></span>

Is the Earth dying? if so answer, and put the reason's why Earth is dying and what we can do to help Earth stop dying.
GenaCL600 [577]

Answer:

Earth has been our place for many years. all inhabitants on earth are causing great destruction. along the way we tried to resolve issues yet some we couldn't figure out. the one we couldn't figure out had made a great impact on our world today. Just how do we stop it? Many ways actually, taking pollution for example. pollution is a great cause for why earth isn't as lively as before. along the years we've polluted 92% of the earths air. causing us to breathe unhealthy air. We can easily fix this problem with finding new ways to get somewhere like riding a bike or taking an energy efficient car. Therefore, we humans have change the world dramatically by doing good things and bad things, too. but in the end we are the ones causing earth to nearly give up, so we can also be the ones to let the earth forgive.

hope this helps you out!

TIP: change it up so you don't do plagiarism:)

Translation ends when
Y_Kistochka [10]

<span>Translation

</span>Remember that transcription happens in the nucleus as it changes from DNA to mRNA.  In translation,
    the mRNA first has to leave the nucleus and go into the cytoplasm of the cell.  The process of translation actually occurs in the cell’s ribosomes.

<span>
</span>The process of translation uses the genetic code on the mRNA strand to direct the construction (making) of a protein molecule. <span>
</span>1.  A ribosome attaches to an mRNA molecule in the cytoplasm.<span>
</span>2.  As each codon passes through the ribosome, tRNA molecules bring the matching amino acids into the ribosome.  Each tRNA has a set of 3 unpaired nitrogenous bases called an anticodon which matches up with the codon coming through the ribosome.  So one end of a tRNA has an anticodon and the other end carries the amino acid which is how the code is translated.<span>
</span>3.  The ribosome and the rRNA molecules it contains attach the amino acids together as they are being translated.  The protein chain will keep growing until the ribosome reaches the stop codon on the mRNA.  At that point, translation is done and the ribosome lets go.


Hope this helps!!!

(Experiment 1: Diffusion through a liquid) Does the rate of diffusion correcspond with the molecular weight of the dye?
saveliy_v [14]
The answer to this question would be: False

The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
