You are working in a lab trying to identify a single celled organism. You are not
sure if it is a Protist or a Moneran (Eubacteria or Archaebacteria). What test
would be most useful to determine its identity?
A. Put it in the sun and measure the oxygen levels
B. Determine if it is motile
C. Test its cells for chitin
D. Determine if it has a nucleus
The test that will be most useful to determine the identity of the single-celled organism is to "determine if it has a nucleus".
DIFFERENCE BETWEEN A PROTIST AND MONERAN:
A protist is a member of the kingdom protista characterized by it's single cells and eukaryotic nature.
On the other hand, a MONERAN is a member of the kingdom MONERA and characterized by it's unicellular and prokaryotic nature.
The major difference between Monera and protista is their prokaryotic and eukaryotic cells respectively. Prokaryotic cells do not have a membrane bound nucleus while an eukaryotic cell does.
Since the major difference between Monerans and protists is their possession of a membrane bound nucleus, the identity of the single-celled organism is to "determine if it has a nucleus".

What is meant by the term base-pairing? How is base-paring involved in DNA replication?
Answer: Hydrogen bonds form only between specific base pairs. ase pairing ensures that the complementary strands produced are identical to the original strands.
Explanation:
You added 20 g of NaCl to 100 g of water. What is the percent by mass of the solute?
Answer: We are given:
Mass of solvent (water) = 100 grams
Mass of solute (NaCl) = 20 grams
Mass of the Solution:
Mass of Solution = Mass of Solute + mass of Solvent
100 + 20 = 120 grams
Mass Percent of NaCl:
We know that
mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100
replacing the variables
Mass% of NaCl = (20 / 120)*100
Mass% of NaCl = 100 / 6
Mass% of NaCl = 16.67%

Why do disruptive selection pressures tend to favor rapid evolutionary changes?
a. They result in sudden gene frequency changes.
b. They eliminate extreme genetic traits.
c. They select for one variation of a genetic trait.
d. They result in environmental adaptation.
Answer:
The correct answer is a. They result in sudden gene frequency changes.
Explanation:
The evolution of life, its diversity, is reduced to the processes of microevolution or speciation. But not all evolutionary processes in populations end with the formation of a new species. Disruptive selection is a type of natural selection that selects against the average individual in a population. The composition of this type of population would show phenotypes (individuals with groups of traits) of both extremes but with very few individuals in between. Disruptive selection tends to increase intra-population variability and, to this end, favors individuals at both ends of the phenotypic distribution, that is, as a final result there is a break in two different populations, which can lead to speciation.

A"They result in sudden gene frequency changes."Explanation:

(PLEASE HELP I WILL MARK BRAINLEST) Limestone is a sedimentary rock and marble is a metamorphic rock. Despite limestone and marble having the same chemical makeup, which statement describes why they are classified as different rocks?
They formed at different times.
They were formed from different fossils.
They were formed by different methods.
They formed in different amounts of time.
Answer:
The were formed by different methods
They were formed by different methods is the statement that describes that limestone and marble are classified as different rocks.Therefore, the correct option is C.
What is limestone?Limestone is a sedimentary rock primarily made up of calcium carbonate (CaCO3) in the form of the mineral calcite. It is formed from the accumulation of shells, coral, and other debris from marine organisms.
Marble is a metamorphic rock that forms from limestone, which is a sedimentary rock composed primarily of calcium carbonate (CaCO3). It is formed through a process of metamorphism, which involves the transformation of the original rock through heat and pressure over time. Therefore, the correct option is C.

which statement describes what happens with ATP during glycolysis?
A) more ATP is produced than is used
B) glycolysis splits ATP
C) more ATP is used than is produced
D) glycolysis does not make any ATP
Answer:
A. more ATP is produced than used
Explanation:
Regulation of glycolysis
Several steps in glycolysis are regulated, but the most important control point is the third step of the pathway, which is catalyzed by an enzyme called phosphofructokinase (PFK). This reaction is the first committed step, making PFK a central target for regulation of the glycolysis pathway as a whole^1

start superscript, 1, end superscript.
PFK is regulated by ATP, an ADP derivative called AMP, and citrate, as well as some other molecules we won't discuss here.
ATP. ATP is a negative regulator of PFK, which makes sense: if there is already plenty of ATP in the cell, glycolysis does not need to make more.
AMP. Adenosine monophosphate (AMP) is a positive regulator of PFK. When a cell is very low on ATP, it will start squeezing more ATP out of ADP molecules by converting them to ATP and AMP (ADP + ADP \rightarrow→right arrow ATP + AMP). High levels of AMP mean that the cell is starved for energy, and that glycolysis must run quickly to replenish ATP^2

Why does DNA need to make a transcript of itself and what is this transcript called?
Answer:
DNA needs to be transcribed itself as a mechanism for the multiplication of its molecules, and this transcription process is called DNA replication.
Explanation:
DNA replication is a mechanism that allows it, from one molecule, to obtain two molecules identical to the original. In other words, it transcribes the information from one of its strands to a new strand.
The process of DNA replication is semi-conservative, because each new molecule is formed by an original strand and a new strand, which contributes to maintaining the integrity of the genetic information.
As a requirement of the cell division process, as mitosis, DNA must replicate so that each daughter cell has the same genetic information as the original cell. This is why replication of this nucleic acid occurs.
