What are factors in an experiment that are not changed but are kept the same for both and normal group and the experiment group?

Answers

Explanation:

The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group.

Which statements compare meiosis I and meiosis II? Check all that apply.

Why do scientists think that all modern plants,
animals, and fungi can be traced to protist
ancestors?

Answers

Answer: Scientists think that all modern plants, animals, and fungi can be trace to protist ancestors because the protists is the root of all eukaryotic diversity. yw.

Scientists think that all modern plants, animals, and fungi can be trace to protist ancestors because the protists is the root of all eukaryotic diversity. ... The function that do cilia and flagella in protists carry out is movement. The first multicellular animals presumably evolved from colonial protists (most likely choanoflagellates), and within the colonies, cells progressively differentiated from one another, acquiring specific functional characteristics. It may sound like a bit of a stretch, but in fact such a phenomenon can be observed in colonies of extant unicellular organisms, both prokaryotes and eukaryotes, where some cells of the colony can become differentiated under particular environmental conditions. We can speculate that early in the history of animals some differentiation genetic programs evolved, got stabilized, and became inheritable from one generation to the next. Once different populations of cells were established in the colony, the door was opened to further specialization. Specialized cells were not initially grouped in organs but were more like regionalized populations or layers of cells, as we see in sponges, and morphogenesis progressively evolved

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.

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.

Answers

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

quizleet Using the information in the introduction on mutations and your knowledge of proteins, develop a hypothesis to explain how the changes in the MC1R protein amino acid sequence might affect its function.

Answers

Answer:

Dark colour occurs.

Explanation:

The amino acid changes in the MC1R protein may change the structure and function of the protein because the amino acids are the building blocks of proteins. This change in amino acid leads to increased production of eumelanin, which results in the dark color of the protein. So we can say that change in the amino acids leads to the change in the structure and function of MC1R protein.

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.

Answers

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.

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.
