what is the function of DNA and RNA
Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.
Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.
Answer:
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell 's activities, while RNA converts that code into proteins to carry out cellular functions.
Explanation:
RNA:
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.
DNA:
The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

What is the purpose of greenhouse gases?
Answer:
A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect[1] on planets. Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F),[2] rather than the present average of 15 °C (59 °F).[3][4][5] The atmospheres of Venus, Mars and Titan also contain greenhouse gases.

1. Describe how photosynthesis and chemosynthesis differ in terms of how energy is converted,
Answer:
1) Photosynthesis:
Reactants- 6CO2 (carbon source), 6H2O, light energy
Products- C6H12O6 (organic molecule), 6O2
2) Chemosynthesis:
Reactants- 6CO2 (inorganic carbon source), 6H2O, 3H2S ( chemical energy source)
Products- C6H12O6 (organic molecule), 3H2SO4
Please find the difference in terms of how chemosynthesis and photosynthesis convert energy below
Explanation:
Photosynthesis and Chemosynthesis are both autotrophic forms of nutrition. They differ in the form of energy and reactants' used to power their respective processes.
- Photosynthesis is the process whereby plants synthesize their food (glucose) from carbon dioxide (CO2) and water (H20) in the presence of sunlight as energy, releasing oxygen gas (O2) as a product.
6CO2 + 6H2O -> C6H12O6 + 6O2
- Chemosynthesis, on the other hand, is the process whereby certain bacteria and fungi that lacks access to light synthesize organic food (glucose) from an inorganic carbon soure (carbon dioxide, CO2), water (H2O), and hydrogen sulfide (H2S), used as chemical energy source, releasing sulfates (H2SO4) as a product
6CO2 + 6H2O + 3H2S -> C6H12O6 + 3H2SO4
However, photosynthesis converts solar energy (energy in sunlight) to chemical energy (in glucose) while chemosynthesis converts inorganic chemical energy to organic chemical energy.
The chemical reaction(reactant and product) for photosynthesis and chemosynthesis are as follows:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18S
Photosynthesis reaction:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂This reaction is a reaction between carbon dioxide and water to form sugar and Oxygen in the presence of sunlight.
The chemical equation of photosynthesis can be interpreted as 6 molecules of carbon dioxide reacting with 6 molecules of water to form a simple sugar and 6 oxygen molecules in the presence of sunlight . The names of the reactant and products are as follows:
carbon dioxide + water → Sugar + oxygen
Chemosynthesis reaction:
Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.
Using H₂S as an energy source a chemosynthetic reaction can be represented below:
18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18SFrom the reaction Hydrogen sulphide was used as a source of energy and it reacts with carbon dioxide and oxygen to produce sugar, water and sulphur.
Hydrogen sulphide + carbondioxide + oxygen → Sugar + water + sulphur.

James adds some magnetic marbles to a glass jar full of ordinary marbles, and then shakes up the jar. What do you think will happen to the magnetic marbles?
Answer:
Magnetic marbles will tend to attract each other.
Explanation:
Magnetic marbles are composed of ferromagnetic materials, which indicates that they function as a magnet and have the ability to attract other objects formed by ferromagnetic materials. In this case, we can say that the magnetic marbles attract each other and inside a jar containing magnetic marbles and common balls, the magnetic marbles will tend to attract and group together.
When James shakes the glass jar ; The magnetic marbles will attract each other
The magnetic marbles will attract each other because of the ferromagnetic materials that each magnetic marble contains. marble is a rock ( metamorphic ) that is made up mainly of calcium carbonate .
when rocks/compounds contain ferromagnetic materials they will act as magnets thereby attracting any metallic object or any magnetic material within close proximity. therefore the magnetic marble will attract each other inside the glass jar
Hence we can conclude that When James shakes the glass jar ; The magnetic marbles will attract each other.

Researchers propose a model to explain variation in phytoplankton cell sizes in a marine
environment. They base their model on the idea that smaller cells absorb nutrients more
efficiently. The researchers predict that the mean diameter of phytoplankton cells will
change by 50 micrometers for every 5-kilometer increase in distance from the shore
because of a gradual decrease in nutrient availability. To test their model, the researchers
determine that the phytoplankton cells found closest to shore have a mean diameter of
900 micrometers.
Based on the model, what will be the mean diameter of the phytoplankton cells that are
found 25 kilometers from shore?
Answer:
650 micrometers

What is the variable that affects enzyme function in the example of phosphofructokinase-1?
Answer:
This question is incomplete
Explanation:
The question is incomplete because the example referred to was not stated. However, phosphofructokinase-1 is a key enzyme in glycolysis; it converts/phosphorylates fructose-6-phosphate to fructose-1,6-bisphosphate in the presence of ATP to release ADP. It is a regulatory enzyme in this pathway (glycolysis) because it's function can be affected by an increased ATP to ADP ratio which inhibits the enzyme (phosphofructokinase-1) and indeed glycosis itself.

Explanation:
Compare substrates and inhibitors.
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. ... Not all molecules that bind to enzymes are inhibitors; enzyme activators bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.
Arginine utilizing enzymes in macrophages showed different specificities for various arginine analogues and derivatives as substrates and inhibitors. Isolated arginase was strongly inhibited by L-canavanine(Can) and L-ornithine(Orn) but only slightly by L-homoarginine(Hom) and L-argininamide(ArgNH2). These effects were not or only weakly observed when released urea was measured in long term cell cultures. On the other hand, both L-canavanine and L-argininamide were substrates for arginase in long-term cultures. The known inhibitors of NO synthase were ineffective. The mechanisms of inhibition were different for L-canavanine and L-ornithine, but clear mechanisms could not be identified). NO synthase was studied only in long term cell cultures without purification. Certain N-guanidino (NG)-substituted arginine derivatives caused a marked inhibition while inhibitors of arginase had only slight or no effect. L-homoarginine was also found to be the substrate of NO synthase. The comparison of these effects of arginine analogues and derivatives made possible a computer-aided approximation for the fitting of active centers of these enzymes to their substrates.
