Answer:

probably there would be more carbon in the air and trees help collect carbon. Also if you cut down trees some people cut it by burning it down and if that happens you are making more carbon which is affecting the atmosphere

Roles of bones in bony fish include which of the following?
Rina8888 [55]

Answer:

D All of the above

Explanation:

Like our bones, bones in fish can provide general protection and support to their body.

(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)

The bone is also where the muscles will attach to, which allows for movement.

(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)

Bones can also protect the fish's brain.

(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)

Which best explains why muscle cells are different from blood cells
Rus_ich [418]

Answer:

A mutation occurs during the development of muscle cells but not in blood cells. Different genes are activated in muscle cells than in blood cells. Muscle cells experience different environmental influences than blood cells.

How will you determine which strain is wild type and which strain is mutant? Can you justify your answers using molecular biolog
Levart [38]

Answer: The simplest way is to determine if a strain is mutant is observing morphology, growth rate, double time, etc but it is accurate if you can prove if the strain is deficient in one aminoacid or can't metabolize lactose, etc.

Explanation: A wildtype strain functions normally, for example, can metabolize as a carbon source, glucose, lactose and other sugars, can synthesize all the aminoacids requered for protein synthesis, etc. If a strain suffers a mutation and it is inheritable, the strain become a mutant. Since several mutations can be silent ones, only those that interfere with a process, can be assesed easyly.

For example, if you have several strains and put them in a lactose medium, but some of them cannot growth means that are lactose mutants. Those strains could carry a mutation in genes that encode lactose degrading enzymes or in regulatory genes of the lac operon, etc.

There are 258 g of MgCl2/liter. What is the molarity of the solution?
Zolol [24]

Taking into account the definition of molarity, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

<h3>Definition of molarity</h3>

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles÷ volume

<h3>Molarity of the solution in this case</h3>

In this case, you know that the molar mass of MgCl₂ is 95.21 g/mole [molar mass is the amount of mass that a substance contains in one mole.]

You can apply the following rule of three: If by definition of molar mass 95.21 grams are contained in 1 mole, 258 grams are contained in how many moles?

amount of moles= (258 grams× 1 mole)÷ 95.21 grams

<u><em>amount of moles= 2.7098 moles</em></u>

Replacing in the definition of molarity:

258 g of MgCl₂/liter= <u><em>2.7098 moles of MgCl₂/liter</em></u>

<em />

Finally, the molarity of the solution is 2.7098 moles of MgCl₂/liter.

What results from the addition or deletion of nucleotides in any number except a multiple of 3?
eimsori [14]
Addition or deletion of nucleotides in any number besides 3 results in a "frame-shift mutation."
This is because every 3 nucleotides of DNA/mRNA exons codes for a single amino acid in the synthesis of a protein. This triplet codon theory means that if 3 nucleotides are added or deleted then an amino acid will be added or lost, but subsequent codons and amino acids will still be read correctly.
However, if any number of nucleotides other than 3 are added or removed, then the codons following the mutation will be out of "sync," in terms of the reading order.
Hence it is called a frame-shift mutation because it shift the reading frame when translating nucleic acids into proteins. Frame shifts will lead to the wrong amino acids being adding in the wrong order for the rest of the code after the mutation.
