Explanation:
free convection
This transfer of heat energy away from the ground by the vertical movement of air is called "free convection" or "natural convection." A hot air balloon rises because warmer air is less dense than cool air.

If a cytosine replaces a guanine in a strand of DNA, this is known as what type of mutation?
Substitution mutation
Deletion mutation
Insertion mutation
Corruption mutation
Answer:
substitution
Explanation:
c replaces g. does not cause a frameshift mutation so it is not insertion or deletion, and i have no clue what corruption is when there is the word "replace" it is probably substitution.
Answer:
Substitution mutation
Explanation:
Mutation refers to a change in the genetic sequence of an organism. Mutation can be of different types depending on how it occurs. A type of mutation called SUBSTITUTION MUTATION involves the replacement of a nucleotide base by another in a gene.
For example, as stated in this question, when a cytosine (C) replaces a guanine (G) in a strand of DNA, it is called SUBSTITUTION MUTATION because guanine base replaces cytosine base in the sequence.

Ocean currents store energy and help to distribute heat and
Answer:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

Answer:
Open system: has the transfer and exchange of matter and energy in the system's surroundings.
Closed system: has a limit to how much matter is exchanged.

What are the advantages and disadvantages of the serial dilution-agar plate procedure?
Answer:
Advantages
- Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies.
- In biochemistry, serial dilution is used to obtain the desired concentration of reagents and chemicals from a higher concentration.
- In pharmaceutical laboratories, serial dilution is performed to receive the necessary concentration of chemicals and compounds as this method is more effective than individual dilutions.
- In homeopathy, homeopathic dilutions are used where a substance is diluted in distilled water or alcohol. It is believed than dilution increases the potency of the diluted substance by activating its vital energy.
Disadvantages
- An error might occur during the propagation of the sample, and the transfer inaccuracies lead to less accurate and less precise transfer. This results in the highest dilution to have the most inaccuracies and the least accuracy.
- Because serial dilution is performed in a stepwise manner, it requires a more extended period of time which limits the efficiency of the method.
- Serial dilution only allows the reduction of bacteria/cells but not the separation of bacteria/cells like in other techniques like flow cytometry.
- This technique also requires highly trained microbiologists and experts in aseptic techniques.

Explanation:
You have a circular plasmid containing 9 kb of DNA, and you wish to map its EcoRI and BamHI sites. When you digest the plasmid with EcoRI and run the DNA on a gel, you observe a single band at 9 kb. You get the same result when you digest the DNA with BamHI. When you digest with a mixture of both enzymes, you observe two bands, one 6 kb and the other 3 kb in size. Explain these results. Draw a map of the restriction sites.
Answer:
A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both
Explanation:
Circular plasmid containing : 9 kb of DNA
Eco R1 and Bam H1 are known as restriction sites in DNA ( i.e. special sequences found in a DNA ) hence they can be specifically cleaved by the restriction enzymes enabling the insertion of a gene. that is why you will get a same result when you digest the Plasmid with either Eco R1 or Bam H1
but A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both

A ______ is a type of turbine used to capture the energy of moving air. A. geotherm B. windmill C. solar panel D. dam
Answer:
b windmill
Explanation:
A windmill is a type of turbine used to capture the energy of moving air.
Windmills have been used for centuries to power grain mills, water pumps, and other mechanical devices. In modern times, wind turbines are often used to generate electricity on a large scale.
Wind turbines typically consist of a rotor with two or three blades that spin around a horizontal or vertical axis. As the wind blows, it pushes the blades, causing them to rotate and give energy. The rotating blades turn a shaft, which is connected to a generator that produces electricity.
Wind turbines can range in size from small turbines used to power individual homes or businesses to large utility-scale turbines used to generate energy for the grid.

What is soil structure?
Answer:
Soil structure is defined by the way individual particles of sand, silt, and clay are assembled. Single particles when assembled appear as larger particles. These are called aggregates.
Explanation:
Aggregation of soil particles can occur in different patterns, resulting in different soil structures. The circulation of water in the soil varies greatly according to structure, Therefore, it is important for you to know about the structure of the soil where you plan to build a fish-farm. Although you may not be able to assemble all this information yourself, the specialized technicians from the soil testing laboratory will be able to provide it after examining your undisturbed soil samples. They will be able to tell you if your soil has bad structure or good structure (pores/capillary canals, network, etc.). They will also be able to tell you about the degree of water circulation or permeability.
