The option that best represents an example of carbon fixation would be the incorporation of CO2 into organic molecules.
Carbon fixation refers to the process of converting atmospheric carbon, mostly in the form of carbon dioxide, to organic molecules in the form of carbohydrates, usually in living organisms.
In living organisms carbon is fixed either via photosynthesis or chemosynthesis.
During the photosynthetic process, inorganic carbon in the form of carbon dioxide combines with water and is converted into carbohydrates in the presence of radiant energy. The process usually happens in green plants.
During chemosynthesis, carbon dioxide reacts with H2S instead of water to arrive at carbohydrates. The process usually happens in chemosynthetic bacteria.

The process of photosynthesis is the best example of carbon fixation.
In the process of photosynthesis, energy from sunlight drives the carbon fixation pathway. photosynthesis process is used by the primary producers such as plants, algae, and cyanobacteria. They contain green pigment named chlorophyll that used the Calvin cycle to fix carbon.
The carbon atom present in the atmosphere in the form of carbondioxide gas fixes by the producers in the form of glucose which have 6 carbon atoms so we can conclude that photosynthesis is the best example of carbon fixation.

All of the following will help the skin to fight infection but one. Which of the following will have little effect on the skin's ability to fight infection? Group of answer choices More tight junctions between keratinocytes of the stratum corneum. Greater production of melanin. Increased secretions of defensins from skin cells. Greater production of keratinocytes resulting in more layers of the stratum corneum.
In order for the skin to fight off infection more efficiently and of the options listed, the correct choice would be for the skin to secrete more defensins.
Keratinocytes are the cells that constitute the epidermis. They are the most dominant cell type in this region and function to create and maintain this barrier. Though this barrier that they create does in fact aid in avoiding bacterial infection, it does little to fight off an already existing infection.
The correct answer is for the skin cells to secrete a greater number of defensins. These are small cationic proteins which are known as "Host Defense Peptides". What this means is that these defensins will either have direct anti-infection properties, or they will act as signals for the immune system.

A spring with a spring constant of 5 N/m is stretched by John until extended by 1 m. How much elastic potential energy is stored by the spring?
Answer:
0.719m
Explanation:
if the load/ deflection curve of the spring has Force (N) on the y axis and Deflection (m) on the x axis then the slope of the curve is 85 N/m
The energy is the area under the curve ie Base x Height/2
Area (22) = Deflection x (Deflection x 85) /2
Therefore, Def = Sqrt(22 x 2 /85)
Answer:
2.5J
Explanation:
Elastic potential energy = ½ ke²
½ x 5 x 1² = 2.5

The fossils that scientists find and study today formed thousands to millions of years ago. But, you can simulate the process of fossilization. Follow these steps to model a fossil:
Line the inside of the plastic container with plastic wrap.
Let the ends of the plastic wrap hang out of the container. The overhanging ends will allow you to more easily lift out your formation when it’s complete.
Pour four inches of water into the container. Use a ruler to measure the correct depth.
After adding the water, add two inches of sand.
Spread the twigs and leaves in a thin layer on the top of the sand.
Stay safe! Use gloves when handling the leaves and when checking the inside of your model during the weeks to come. Wash your hands and gloves when you are done.
Part A
After assembling the materials, record your observations. Describe what the setup looks like and the color of the leaves and twigs. Predict what changes will take place over the next few weeks.

True or false compared with the other substances water requires a lot of heat to increase its temperature
True. Water has a high specific heat capacity (4.18J/g/K) compared to other substances, thus more heat is required to raise its temperature. This can be explained by water's strong hydrogen bonds.

during the experiment measuring energy production in plants, the highest rate of cellular respiration occurred in
Inferring that the experiment in question seeks to measure the rate of energy production in various stages of plant life, we can conclude that the highest rate will be measured in germinating seeds.
The way in which plants produce energy can vary between the species of plants as well as the stage in the plant's life cycle. In broad terms, plants produce energy through cellular respiration.
Cellular respiration is the process by which cells use oxygen or other nutrients and turn it into an energy molecule known as ATP through a series of metabolic reactions. In plants, this occurs in the chloroplasts.
Once the required environmental conditions are met a seed begins to germinate. When this occurs, the seed begins to:
Absorb increased amounts of waterMobilize nutrient reservesGrow rapidly.All of these will require energy molecules to complete. This rapid and sudden increase in the amount of energy required explains why the highest rate of energy production will be measured in germinating seeds.

Explanation:
The solute potential of a plant cell is -10 bar, and its pressure potential is 3. The plant cell is placed into a solution with a water potential of -10 bar.
What is the water potential of the cell, and in which way will water move?
The water potential of the cell would be -7 bar and thus, water will move from the cell to the surrounding solution.
Recall that:
Water potential = pressure potential + solute potential
For the plant cell, solute potential = -10, pressure potential = 3
Water potential of the cell = 3-10
= -7 bar
The water potential of the cell is -7 bar while that of the surrounding solution is -10 bar. Thus, the cell has a higher water potential than the surrounding solution.
Recall that water usually moves from the region of high to the region of low water potential. Therefore, water will move from the cell to the surrounding solution.

5. Juan’s cell phone company charges $35 a month for the phone service plus $0.50 for each text message. How many text messages does Juan send in a month if his bill was $52? plz help its due today
Answer:
Juan sent 34 text messages in a month
Explanation:
You have to create an equation for your problem!
t = text messages
The equation below represents the charge for Juan's cell phone usage
35 + 0.50t =$
Substitute 52 for "$" since that is the amount of the bill sent to Juan for a particular month.

Human blood consists of blood groups A, B, and O. However, there is one more blood group, AB, which contains alleles A and B in the same genotype. What is this phenomenon called?
A.
coinheritance
B.
codominance
C.
incomplete dominance
D.
polygenic inheritance
Answer:
Coinheritance
Explanation:
It is coinheritance because, if the placement of the A and B molecules on each cell is controlled by the proteins that are coded by different versions of the same gene, then IA and IB are codominant but both are dominant to Io. If a person receives an IA allele and a IB allele, their blood type is type AB, in which characteristics of both A and B antigens are expressed.

Explanation:
The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell's ribosomes. Following assembly, ribosomes are transported to the cell cytoplasm where they serve as the sites for protein synthesis. Within the cell nucleus there's a very specific part called the nucleolus. This does not contain the chromosomes. What this contains is the machinery necessary to assemble the cell's ribosomal RNAs.
how parrotfish affect the carrying capacity of coral reefs
Answer:
Explanation:
Parrotfish spend 90% of their day cleaning the reef of algae. This cleaning (eating) helps corals grow and thrive, and healthy reefs support more fish in the sea. ... They snack on the hard parts of coral which becomes a white sandy material in their stomachs that they leave behind on the reef.
