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?
ey's Bell Jar...
Abstract
Background
Photosynthesis maintains aerobic life on Earth, and Joseph Priestly first
demonstrated this in his eighteenth-century bell jar experiments using mice and
mint plants. In order to demonstrate the fragility of life on Earth, Priestley's
experiment was recreated using a human subject placed within a modern-day
bell jar.
Methods
A single male subject was placed within a sealed, oxygen-depleted enclosure
(12.4% oxygen), which contained 274 Cz and C plants for a total of 48 h. A
combination of natural and artificial light was used to ensure continuous
photosynthesis during the experiment. Atmospheric gas composition within the
enclosure was recorded throughout the study, and physiological responses in the
subject were monitored.
Results
After 48 h, the oxygen concentration within the container had risen to 18.196, and
hypoxaemia in the subject was alleviated (arterial oxygen saturation rose from
86% at commencement of the experiment to 99% at its end). The concentration
of carbon dioxide rose to a maximum of 0.66% during the experiment.
Conclusions
This simple but unique experiment highlights the importance of plant life within
the Earth's ecosystem by demonstrating our dependence upon it to restore and
sustain an oxygen concentration that supports aerobic metabolism. Without the
presence of plants within the sealed enclosure, the concentration of oxygen
would have fallen, and carbon dioxide concentration would have risen to a point
at which human life could no longer be supported.

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!

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.

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.

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 .
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.

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

Explanation:
Imagine two closely related, but separate, species of fish reproduce and the hybrids offspring have higher fitness than either of the parent species. Given enough time, the most likely outcome will be: Group of answer choices The two original species will eventually fuse into a third new species, and disappear. The two original species will remain, and a third new species will appear. Nothing: the two original species will remain, and the hybrids will eventually disappear.
Answer:
The two original species will eventually fuse into a third new species, and disappear.
Explanation:
According to Darwin's theory of evolution, species that are better adapted to their environment have greater chances of surviving long enough to reproduce and pass on these favourable characteristics to their offspring. This is known as 'survival of the fittest'.
The original species lack the resilience of the new hybrid species hence the two original species will eventually disappear and fuse into the third specie.

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.
