4. Use Models Use your model to compare the administration of an mRNA drug to the
protein synthesis that the cell normally performs.
NOTEBOOK
5. Conduct Research Use an online search engine to research more information about
mRNA drugs, their uses, and their development. Be sure to take notes and to cite your sources.
The text: What happens when you take a conventional drug, such as aspirin or penicillin? The drug
travels through the blood stream, and then is absorbed by body cells or (as with penicillin)
by the cells of bacteria or other invaders. The drug does its work, but eventually it goes
away. Enzymes and other mechanisms break apart drugs and remove them from the body.
Today, researchers are trying to develop drugs in a very different way. The new drugs are a
modified form of messenger RNA (mRNA). Instead of directly completing the tasks of the
drug, the modified mRNA enters the cell and directs protein synthesis. Then the protein
takes action as a drug or medicine. The protein might be a vaccine or antibody, or it might
be an enzyme that the body cannot make or that it needs in an increased supply.
To develop mRNA drugs, researchers had to find a way to make the molecules last longer
in the body than they generally do. They also needed to "trick" the target cell into
recognizing and accepting the drug. Otherwise, the cell might attack the drug as if it were
a virus.
Researchers met both challenges with the same solution. The drug is not quite the same as
the natural mRNA found in cells. Instead, it uses a few nucleotides that are slightly
different from the normal nucleotides found in RNA. The modifications make the mRNA
both more stable and less virus like.
Answer:
The text describes the development of mRNA drugs and how they differ from conventional drugs. mRNA drugs work by directing protein synthesis inside the cells, and the protein produced by the cell acts as the drug. To develop mRNA drugs, researchers had to find a way to make the molecules last longer in the body and to avoid the cell recognizing the drug as a virus. The solution was to modify the mRNA so that it is different from the natural mRNA found in cells, making it more stable and less virus-like. The text does not directly address the hypothesis about whether mRNA can be replaced with other types of RNA for the therapy to work. However, it does suggest that the modifications to the mRNA are key to the drug's effectiveness and stability.

The cells of a certain culture of bacteria triple every 2 minutes. If there are 40 cells in the beginning, in how many minutes will there be more than 9500 cells?.
A specific culture of bacteria has cells that triple every two minutes. If there are 40 cells in the start, there will be more than 9500 cells there in 9.20 minutes.
Since the number of cells triples every 2 minutes, we can write the relationship between the number of cells (N) and time (t) as:
N = 40 x [tex]3^{t/2}[/tex]
where t is the time in minutes.
We want to find out when the number of cells will be greater than 9500.
Dividing both sides by 40, we get:
[tex]3^{t/2}[/tex] > 237.5
Taking the logarithm (base 3) of both sides, we get:
t/2 > log_3(237.5)
Solving for t, we get:
t > 2 x log_3(237.5)
Using a calculator, we can evaluate log_3(237.5) to be approximately 4.60. Therefore,
t > 2 x 4.60 = 9.20 minutes
So it will take more than 9.20 minutes for the number of cells to exceed 9500.

In this project, you will design and conduct an investigation in order to provide evidence that a feedback mechanism helps a living organism maintain homeostasis.
Background
The internal and external environments of living organisms are constantly changing in many ways. To stay alive, a living thing must maintain homeostasis (internal stability). Feedback mechanisms help living systems maintain this stability. A feedback mechanism does this by sensing a change in a condition and causing a response. Thus, it keeps an organism's internal conditions within a tolerable range. A positive feedback mechanism is one that encourages the change that was detected. A negative feedback mechanism is one that discourages the change.
Both the stimulus for feedback and the response can be internal or external. For example, an increase in a person's heart rate while running is an internal response to an internal stimulus. The upward movement of tree sap in spring is an internal response to an external stimulus. A lizard running under a rock to cool off in hot weather and a leaf's stomata opening and closing as the humidity rises and falls are external responses to external stimuli.

. In a salt marsh in Agusan, the quantity of solar radiation reaching the ground during the summer is 7,000,000cal/m2/day. The gross productivity of the producers in the salt marsh (mostly microscopic algae) is 0.0040 g/cm2/day. The average rate of respiration (the respiration requirement) is 35% of the gross primary productivity. Ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories.
The algae in the salt marsh are very efficient in their use of the solar radiation they receive.
What is solar radiation?Solar radiation is the energy emitted by the sun in the form of electromagnetic waves. These waves consist of visible light, infrared radiation, and ultraviolet radiation. Solar radiation is important for life on Earth as it provides the energy for photosynthesis and drives the water cycle.
The amount of solar radiation reaching the ground in a salt marsh in Agusan during the summer is 7,000,000cal/m2/day. This energy is used by the producers (microscopic algae) to photosynthesize and produce organic matter. The gross primary productivity (GPP) of the producers in the salt marsh is 0.0040 g/cm2/day. This means that the algae are able to produce 0.0040 grams of organic matter per square centimetre of salt marsh every day.
The respiration requirement for the algae is 35% of the GPP. This means that in order for the algae to survive, they must use 35% of the GPP for respiration. This leaves 65% of the GPP to be used for growth and other metabolic needs.
Finally, ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. This means that 1 gram of algae in the salt marsh contains enough energy to provide 2,920 calories. This indicates that the algae in the salt marsh are very efficient in their use of the solar radiation they receive.

what is the relationship between a continent and the earth’s plates
Answer:
tectonic plates
Explanation:
The relationship between a continent and the Earth's plates is that continents are part of the Earth's tectonic plates. The Earth's outer shell is divided into several large and many small plates, and the continents sit on these plates. The movement of these plates is responsible for many geological events such as earthquakes, volcanic eruptions, and the creation of mountains. The boundary between two plates is called a plate boundary, and there are three main types of plate boundaries: divergent boundaries, where plates move away from each other and magma rises from the mantle to create new crust; convergent boundaries, where plates collide and one plate is forced beneath the other, leading to the formation of mountains; and transform boundaries, where plates slide past each other and can cause earthquakes. The continents move with the plates, and over long periods of time, this movement has led to the formation and breakup of supercontinents, such as Pangaea.

What is diffusion and osmosis?
How does diffusion and osmosis work?
Answer:
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane, such as the cell membrane. In osmosis, water molecules move from an area of higher water concentration to an area of lower water concentration.
The process of diffusion and osmosis works by having molecules move from a region of high concentration to a region of low concentration. This movement is caused by the molecules having kinetic energy, which causes them to move around randomly. As they move, the molecules spread out, causing the concentration of the molecules to decrease in the area they are moving away from and to increase in the area they are moving towards. This process can be used to explain the movement of molecules across a semi-permeable membrane, such as the cell membrane. In this case, the molecules move from the area of higher concentration (inside the cell) to the area of lower concentration (outside the cell).
Answer:
What is Osmosis are Diffusion
•Osmosis is the process of moving solvent particles across a semipermeable membrane from the solvent’s higher concentration to the solvent’s lower concentration. The complete process does not require energy to take place
•Diffusion is the process of moving particles from a region of higher concentration to a region of lower concentration until equilibrium is reached. Simple diffusion does not require energy; however, facilitated diffusion requires ATP
How they work
•In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
