What is the pathway of blood in the cardiovascular system
Answer: Through the tricuspid valve, the heart moves oxygen-poor blood from the right atrium to the right ventricle. The blood is subsequently pumped by the right ventricle down the pulmonary artery to the lungs, where it enters the respiration process to absorb oxygen and expel carbon dioxide. The oxygen-rich blood then travels through the pulmonary veins back to the left atrium of the heart. Through the mitral valve, the left atrium delivers blood that is oxygenated to the left ventricle. The aorta, which divides into smaller arteries that carry blood to numerous organs and tissues, is how the left ventricle subsequently pumps the oxygen-rich blood to the rest of the body.
. 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.

expression in the cell.)

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.

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.
