An 8-mer oligopeptide has the following amino acids:
A D E E F M W Y (two Es are present)
Here is your evidence:
1. Edman degradation produces A.
2. CNBr produces a 5-mer and a 3-mer that contains W.
3. Chymotrypsin produces two dipeptides and a tetrapeptide. The tetrapeptide has a total net charge of -4 at pH 12.5.
4. Staphylococcal protease in phosphate buffer produces a tetrapeptide (4-mer), dipeptide, free D, and free W.
5. Staphylococcal protease in acetate buffer produces a pentapeptide (5-mer), dipeptide, and free W.
Put in the sequence of the 8-mer (use caps here) i.e. ABCDEFGH.
A mutation always causes a change in a protein or a trait.

If plants were removed from an area, which statement below describes the outcome?
a) Carbon dioxide levels would increase.
b) Oxygen levels would increase.
c) None of the above.
d) Carbon dioxide levels would decrease.
Answer:
"A" they would increase
Explanation:
If plants were removed from an area, then Carbon dioxide levels would increase.
What happens if plants are removed from an area?When green plants prepare their food, they give off oxygen. This is a gas that all animals must breathe in order to stay alive.
Without plants, animals would have no oxygen to breathe and would die. Without plants, there would be no food to eat.
Thus, Carbon dioxide levels would increase.

reasons why cells divide.
Answer:
Cells divide so living things can grow. When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.
Explanation:
Growth. Replacing damage or dead cells.
TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.
e. Regardless of the ratio of RNA to coat protein in the starting mixture, the reassembled virions always contain RNA and coat protein in the ratio of three nucleotides of RNA per coat protein monomer.
Answer:
Explanation:
tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n
In the homeostasis lab we are using ____________________ as a homeostatic parameter.
Answer:
Body temperature
Explanation:
We use body temperature as homeostasis parameter in the lab.
Homeostasis can be described as a self regulating mechanism used by the body systems for stability maintainable so as to adjust to several conditions that are important for survival.
The way the body controls the body temperature in humans is a good description of homeostasis
You are looking at the color of feathers in ducks and find that Green feathers (G) are dominant to yellow feathers (g). However, a second gene, H, controls whether the color will be expressed in the feathers. If the duck is hh, the duck will always be white, because the pigment does not go into feathers. What ratio of phenotypes in the progeny would you expect following a dihybrid cross

Which statements are true?
1 and 2
2 and 3
2.4 and 5
3.4 and 5
Answer: 2, 4 and 5.
Explanation:
Human system are made of various organs which in turn are made up of various tissues which in turn are made up of various cells. Cells are therefore much more numerous than systems.
As already mentioned, organs are made up of tissues which are made up of cells so statement 4 is right.
As systems are made up of various organs working together, they are more complex than the individual organs. For instance, the Muscular system is more complex than the triceps or bicep muscles.
