Both DNA and RNA are synthesized by covalently linking a nucleoside triphosphate to the previous nucleotide, constantly adding to a growing chain. In the case of DNA, the new strand becomes part of a stable helix. The two strands are complementary in sequence and antiparallel in directionality. What is the principal force that holds these two strands together
Answers
Answer:
The correct answer is - hydrogen bond.
Explanation:
Hydrogen bonding is very essential for life on earth. DNA has a double-helix structure that means it has two distinct strands in its structure and hydrogen bonds hold together the nitrogen base pairs in the middle. In absence of hydrogen bonds, DNA would have to exist as a different structure. The principal force or bonds between those two strands are Hydrogen bonds between the nitrogen bases. Adenine always makes a hydrogen bond with Thymine whereas Guanine always binds with cytosine.
Thus, the correct answer is - hydrogen bond.

If you were a chemical engineer tasked with developing a photosynthesis inhibitor to be used in agriculture, propose which part of photosynthesis your chemical would target. What do you think some of the “unintended consequences” of this work might be, if successful?
Answers
By attaching to particular locations on the photosystem II complex in plant chloroplasts, photosynthesis inhibitors thwart the process of photosynthetic (food production) in sensitive plants.
What are photosynthesis inhibitor?Membrane disruptors are another name for contact herbicides, which are those that prevent Photosystem I from functioning.
Herbicides obstruct photosynthesis by binding to D1 proteins of the photosystem II complex in chloroplast thylakoid membranes.
Herbicide binding to this protein prevents electron transport, halts the fixation of CO2, and halts the synthesis of the energy required for plant growth.
Therefore, photosynthesis inhibitor block the function of photosystem inside the chloroplast.

Organic semiconductors are a new technology that scientists are considering for the next generation of solar
panels. Manufacturers want to produce efficient semiconductors at a low cost. Which type of organic
semiconductors would be most desired as a solar panel technology?
Answers
The specific properties of the most desired organic semiconductors for solar panel technology may evolve as advancements are made in the field.
In the context of solar panel technology, the most desired type of organic semiconductors would typically possess the following characteristics:
High Efficiency: The organic semiconductors should have a high power conversion efficiency, meaning they can efficiently convert sunlight into electricity. This is crucial for maximizing the electricity output of solar panels.
Tunable Bandgap: Organic semiconductors with a tunable bandgap would be advantageous. The bandgap determines the range of light wavelengths that can be absorbed by the material. A tunable bandgap allows for optimization to match the solar spectrum, enabling better absorption of sunlight and improved overall efficiency.
Long Operational Lifetime: The organic semiconductors should be stable and exhibit a long operational lifetime. Solar panels are expected to endure outdoor conditions for many years, so the materials used should be resistant to degradation, such as from exposure to UV radiation or moisture.
Scalability and Low Cost: Manufacturers aim to produce organic semiconductors on a large scale at a low cost. Therefore, desirable organic semiconductors should be readily synthesized using cost-effective methods and be compatible with high-volume manufacturing processes.
Environmental Friendliness: Organic semiconductors that are environmentally friendly and have low toxicity are desirable. This is aligned with the goal of sustainable and clean energy technologies.
It is important to note that the field of organic semiconductor research is still evolving, and scientists are continually working to improve the performance and characteristics of these materials.

If sea otters were removed from the food web, what effect would that have on other tropic levels?
A. The kelp population would increase in size
B. The kelp population would decrease in size.
C. The elephant seal population would start eating kelp.
D. The population of kelp crabs would immediately decrease.
E. The population of sea urchins would immediately decrease
Answers
Answer:
E. The population of sea urchins would immediately increase, which could lead to a decrease in the size of the kelp population over time as the sea urchins consume more kelp.
Explanation:
If sea otters were removed from the food web, the population of sea urchins would immediately increase. This is because sea otters are a natural predator of sea urchins, and they help to control the sea urchin population. When sea otters are removed, the sea urchin population can grow rapidly and consume large amounts of kelp, which is a primary food source for many organisms in the ecosystem.
Therefore, the answer is E. The population of sea urchins would immediately increase, which could lead to a decrease in the size of the kelp population over time as the sea urchins consume more kelp.
\The data in the table were recorded during an investigation in which a paramecium was placed in a hypertonic salt solution.

Which statement correctly describes the bars on a bar graph representing the data?
The graph has five bars of equal height.
The bars range from tallest for very high concentration to shortest for very low concentration.
The bar for very low concentration is twice the height of the bar for medium concentration.
The bar for very high concentration is five times the height of the bar for very low concentration.
Answers
The table Paramecium Contractile Vacuole Contractions which correctly describes the bars on a bar graph representing the data is the bars range from tallest for very high concentration to shortest for very low concentration.
The data in the table records the number of contractions per minute of a paramecium's contractile vacuole in response to different salt concentrations in the surrounding environment.
A bar graph representing this data would have five bars, one for each level of salt concentration.
The bars would vary in height according to the number of contractions per minute, with the tallest bar representing the highest salt concentration and the shortest bar representing the lowest salt concentration.
Therefore, the correct statement describing the bars on the bar graph would be: "The bars range from tallest for very high concentration to shortest for very low concentration."
This statement accurately describes how the height of the bars would vary based on the data in the table.
The other statements do not accurately represent the data or the trends observed in the table.

Renewable resources are those resources which are inexhaustible in nature . It means these resourses are present in unlimited quantity and are environment friendly.
Geothermal energy is one of the example of renewable resources.
In geothermal energy, The word ' geo' stands for earth. So ,It basically means the energy that is extracted from the earth.
Here are some uses for the utilisation of renewable geothermal energy.
Geothermal energy helps in generating electricity.The geothermal power plant extract the heat from geothermal reservoirs. Then, This extracted heat is transfer to the heat engine .Which are responsible for running the heat engine smoothly and generation of electricity.
Geothermal energy helps in heating greenhouse .The heat that is released from the underground reservoirs are used to reduce green house gases because Geothermal energy needs very less CO2 . This heat is transfer in green house and it results into direct heating of green houses.
It also act as a tourist spotThere are so many people who wish to enjoy their leisure time peacefully. In winters, People like to visit the areas where hot spots are found .Which is a example of geothermal energy.
Geothermal energy helps in heating and cooling buildingsThe warm water is taken from underground reservoirs and then converted into hear energy. Then this heat energy is transfer in the building by using geothemal pumps helps in generating heat in building in winter. This same process is also follows for cooling of building.
It is also used as industrial purposeGeothermal energy is also used in industries for cooking, pastuerizing milk etc.
