I'm Having Trouble Wording How I Would Describe The Molecular Change In Chocolate When Melted. I'm Asked

Answers

Answer 1

Answer:

When chocolate melts, the molecules in the chocolate gain more freedom of movement. To correctly show this change in a model, you can add a layer of movement to the molecules, such as showing them vibrating or rotating. You can also show the molecules breaking apart and reforming into different shapes, as they gain more freedom of movement.

Using compaction and cementation explain why sedimentary rocks are not just a loose pile of sand and rocks.​

Answers

Compaction and Cementation They are compacted, reducing the available pore space and expelling much of the pore-water. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.

Through compaction and cementation, minerals form a crusts on the sedimentary rocks which are no longer just a loose pile of sand and rocks.

What are sedimentary rocks?

Sedimentary rocks are formed from the pre-existing rocks or pieces of or fossils of living organisms. They form from the deposits which accumulate on the surface of Earth. Sedimentary rocks often have distinctive layering or bedding over Earth.

Dissolved minerals present in the ground water precipitates from the water surface present in the pore spaces forming mineral crusts on the sedimentary grains, which gradually undergo cementing the sediments, which thus lead to formation of a rock.

If a DNA strand contains 12% thymine, it also contains ____

a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C

Answers

Answer:

If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.  

Explanation:

A=T
so A is 12% too
100-(12+12)
=100-24
=76
then divide by 2 to get each C and G
76/2=38
so C and G are each 38%

the answer is option A

The number of neurotransmitter molecules located within a specific synaptic gap would most clearly be
reduced by

Answers

Answer:

The correct answer is - reuptake.

Explanation:

The process that reabsorbs the neurotransmitters known as reuptake which reduced the number of neurotransmitter molecules. Neurotransmitter transporter found on the outer membrane of the plasma membrane assists the process of reuptake by reabsorbing the neurotransmitter molecules from the specific synaptic gap. Neurotransmitters recycle by this process in order to reuse again after a time for the particular signal to last.

Thus, the correct answer is - reuptake.

Find the edge length of the cube. (The density of copper is 8.96 g/cm3, and the volume of a cube is equal to the edge length cubed.)

Express your answer with the appropriate units.

Answers

Answer:

[tex]x = 2.13\ cm[/tex]

Explanation:

See comment for complete question

Given

[tex]Mass = 87.2g[/tex]

[tex]Density = 8.96gcm^{-3[/tex]

Required

Calculate the edge length of the cube

First, we need to calculate the volume of the cube using:

[tex]Density = \frac{Mass}{Volume}[/tex]

Make Volume the subject:

[tex]Volume= \frac{Mass}{Density }[/tex]

Substitute values for Mass and Density

[tex]Volume= \frac{87.2g}{8.96gcm^{-3}}[/tex]

[tex]Volume= \frac{87.2cm^3}{8.96}[/tex]

[tex]Volume= 9.73cm^3[/tex]

Represent the edge length with x.

So:

[tex]Volume = x^3[/tex]

Substitute x^3 for Volume in [tex]Volume= 9.73cm^3[/tex]

[tex]x^3 = 9.73cm^3[/tex]

Take cube root of both sides

[tex]x = \sqrt[3]{9.73cm^3}[/tex]

[tex]x = 2.13\ cm[/tex] --- approximated

Hence, the edge length is 2.13cm

Explanation:

The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.

Answer:

a. the second nucleotide is wrong. It is a U but should be an A. No other nucleotides were effected by this, only the one was effected. This is a Point (Substitution) Mutation.

b. the third nucleotide is wrong. It is a T that was inserted. As you can see, the rest of the nucleotides are right, but since the T was added, it will mess up how the rest of the sequence is read. It will be read UAT GGC GAA... instead of UAG GCG AAU... see how it messed it up? This is an Insertion (Addition) Mutation.

c. the second nucleotide was deleted. This is called a Deletion Mutation. It will mess up the rest of the sequence, similar to how the example above did.
