When prokaryotic bacterial cells undergo cell division, the single circular chromosome replicates to form a second chromosome. This new chromosome, like the original, attaches to the plasma membrane. Next, the plasma membrane pinches inward, and a cell wall forms across the middle of the cell to separate the two chromosomes and form two daughter cells. How does cell division in bacteria differ from mitosis in eukaryotes?
Bacteria have these things:
A. Cell wall, nucleus and cell membrane
B. No membrane bound organelles, cell membrane and cell wall
C. No DNA, cell membrane and no cell wall
D. Have no organelles or DNA

Explain what would happen to the food chains if:
a.) A toxin was released into the local water supply, and the mice in the meadow died.
b.) There was an increase in the hawk population.
a. The hawks would die because the mice died, since the bottom part of the food chain was taken out, the whole food chain would fall apart;
b. All the mice would die; since there are more hawks to eat the mice, the mice would be eaten faster than they could reproduce, and they would slowly die out.
Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the addition of a certain amino acid to a specific tRNA. c The biological role of restriction enzymes is to: A) aid recombinant DNA research. B) degrade foreign DNA that enters a bacterium. C) make bacteria resistant to antibiotics. D) restrict the damage to DNA by ultraviolet light. E) restrict the size of DNA in certain bacteria.
Answer:
C) are sequence-specific DNA endonucleases
Explanation:
Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are EcoRI, BamHI and HindIII, isolated from Escherichia coli, Bacillus amyloliquefaciens and Haemophilus influenza, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.

How is a molecule like glucose related to an organism?
Glucose is combined with oxygen and releases usable energy, carbon dioxide, and water. Cells can use that extra energy to power their functions. The energy isn't just floating around....ATP is the power molecule used by all the cells of an organism to power the secondary reactions that keep us alive. Hope this helps, if you need more calrafocation feel free to ask me in the comments!
A molecule of glucose that plays a vital role in the metabolism of the most of living organisms. Glucose is the 6 carbon molecule which plays the an important role in the metabolism cycle and the chain.
What is the molecule that is related to the glucose ?A molecule like glucose that is related to the glucose is the galactose which is also a sugar.
Glucose is a sugar that plays a vital role in the metabolism of most living organisms. It is manufactured by plants and certain bacteria and protists during photosynthesis. Glucose is the main source of chemical energy for cell functions in organisms from bacteria and plants to humans.
Photosynthesis requires the sunlight with carbon dioxide and water as the starting reactants. When the process completes, photosynthesis releases the oxygen and produces the carbohydrate molecules when the most commonly compound is glucose. These molecules contain the energy molecules that are living things that need to survive.

Explain what happens to the body temperature of the rattlesnakes as day turns to night
[tex]\huge\bold\red{Answer}[/tex]
It bears repeating that reptiles potentially dangerous to man account for only a small proportion of Nevada’s herpetofauna. Of the twenty-five snake species found here, only the six rattlesnakes pose any possible threat. Similarly, of twenty lizard species native to Nevada, only the Gila monster is venomous. The vast majority of reptiles found in Nevada (and elsewhere) are completely harmless!

Analyze your results. Which type of liquid will prevent the apple from turning brown?
Answer:
Lemon
Explanation:
The process in which the exposed "interior" of an apple becomes/turns brown is caused by enzymatic actions in the apple. This browning reaction occurs in many fruits and tubers (like banana and yam). This process requires oxygen to proceed and hence can be restricted by the presence of an antioxidant. Ascorbic acid is an antioxidant that can assist in countering the effect of the oxygen molecules in this browning.
Lemon contains a good amount of ascorbic acid which can assist in counteracting the effect of oxygen and prevent the browning from taking place.

Answer: Cells : Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
virus : A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
Both : Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that's used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve.

Carrie is conducting an experiment on a solution. The solution’s initial pH is 10. Then, as Carrie gradually adds Compound X into the solution, the pH decreases to 5. Which is the most likely identity of Compound X? *
Answer:
Compound X must be an acid
Explanation:
Acids have a lower pH than alkaline solutions. When you add an acid to a solution, the pH drops, as has happened here. If the pH did not change, we would assume compound X was neutral. If the pH increased, we would assume compound X was even more alkaline than pH 10.

The mountains of the Sierra Nevada play a role in the formation of desert in eastern California and Nevada.
What is this an example of?
Answer:
The correct answer would be - The lithosphere influences the atmosphere and biosphere .
Explanation:
The mountains of the Sierra Nevada play the role of a barrier that blocks the air or wind that brings the clouds filled with water to eastern California and Nevada as it can not pass the mountains and reach the other side of mountains which cause less or no rain to this region.
Rain is a very important aspect for the region to be less diverse in plants and animals as most of them require water but as it is described there is no or very little precipitation so it becomes desert.
This makes it an example of the lithosphere influences the atmosphere and biosphere .

Fat and ATP are different molecules that can both be described as molecules that store
energy. Compare the functions of these molecules in terms of energy storage.
A) O ATP molecules are made when where there is an excess amount of energy,
while fat molecules are used immediately.
B) O ATP molecules are used for long-term storage, while fat is used for
immediate energy
C) O Fat molecules are stable and can be stored for a long time, while ATP is not.
D) O Fat molecules are unstable and can be stored short-term, while ATP
molecules are stable and stored long term.
Answer:
C) Fat molecules are stable and can be stored for a long time, while ATP is not.
Explanation:
ATP is short-term energy, and fat is long-term energy and is used when when there is no more energy. Fat molecules are also highly stable because of the many covalent bonds
Answer:
C, i think
Explanation:
ATP is short term storage due to the fact that it is produced rapidly and used up just as fast in cells. Fat is long term, usually when there is no energy, fat is burnt up (during exercise is the most common) and used for energy
