Answer:
Complimentary base pairings
Answer:
-Complementary base pairing
Explanation:
DNA probes can be defined as fragments of single stranded DNA molecules, which are used to to detect the presence of target DNA sample. The nucleotide sequence in probes is complementary to the nucleotide sequence of target DNA.
Hence, probes detect DNA by hybridizing to single stranded target DNA according to complementary base-pairing rule. Nitrogen bases present in probe and target DNA make hydrogen bonds with each other (adenine binds with thymine and guanine binds with cytosine (and vice versa) and target DNA is detected.
Thus, the correct answer is 'complementary base-pairing.'
One important abiotic factor in marine ecosystems is the a. amount of plankton. c. kinds of algae. b. water depth. d. size of animals. Please select the best answer from the choices provided
Answer:
b. water depth
Explanation:
The abiotic factors are the factors that are not part of the biosphere, thus they are not living organisms. In this case, the water depth is that type of factor that would influence the marine ecosystems. The depth of the water is crucial for the type of organisms that can exist in it, their density, and diversity. This is because the water has certain characteristics that provide certain conditions, like if the water is shallow, it will be warmer, but if its deep, then it will be colder. The amount of nutrients in it also depends on the depth. The sunlight can penetrate into the water only in the shallow parts, but not in the deep ones, so the basis of the ecosystems, the producers can exist only where they can have sunlight to perform the process of photosynthesis.
Water depth is an important abiotic factor in marine ecosystems, as it influences the distribution and abundance of marine organisms.
Explanation:One important abiotic factor in marine ecosystems is the water depth. Water depth plays a crucial role in determining the distribution and abundance of marine organisms. Different depths provide varying levels of light, temperature, and pressure, which in turn influence the types of organisms that can survive in a particular marine zone.

Chromatic aberration ___.
Chromatic aberration is a color distortion that occurs when a lens fails to focus all colors at the same point due to different refractive indices for different wavelengths of light, with violet being bent more than red. Multiple-lens systems can partially correct this aberration.
What is Chromatic Aberration?
Chromatic aberration refers to the phenomenon where a lens is unable to bring all wavelengths of color to the same focal plane, resulting in a distortion of color at the edges of objects. This occurs because different colors of light have different refractive indices in a lens material, thus they are bent by different amounts when passing through a lens. Violet light has a shorter wavelength and is bent more than red light, making the lens more powerful for violet than for red. This leads to violet light being focused closer to the lens, causing images to appear with different colors, locations, and magnifications.
To mitigate this effect, multiple-lens systems may be employed, which can partially correct chromatic aberrations by combining lenses made of different materials. However, this solution can increase the complexity and cost of optical systems such as cameras.
when a solvent equally disperses throughout a solution what type of transport is this
Answer:
Diffusion
Explanation:
Diffusion is the homeostasis of solvents
Answer:
Diffusion (a passive transport)
Explanation:
Diffusion refers to the passive movement of substances from the region of higher concentration to that of lower concentration. Uniform distribution of solvent throughout the solution occurs when molecules of solvents diffuse in all directions to equalize their distribution in the solution. Since it does not need the input of energy, diffusion is a type of passive transport.
The growth of bacteria is determined not only by the composition of their surroundings but also by sudden changes in the living environment. For rapid growth in different environments, bacteria need to adjust their enzyme levels in order to rapidly benefit from the nutrients currently available in their surroundings. If the living environment undergoes rapid changes, the bacterium’s own production of proteins has to conform to these changes in an effective way. How are bacteria able to adapt to a rapidly changing environment?
Answer:
Bacterial genes are organized into clusters of coregulated genes, that are regulated such that they are all turned on or off together.
(hope this helps)
Answer:
Bacteria can adapt to environmental changes thanks to their effective mechanism for regulating gene expression, that is, mechanisms that bacteria have effective mechanisms to control which genes are expressed and at what levels. Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into the mRNA. These molecules act by binding to DNA near the gene and help or block the transcription enzyme, RNA polymerase. Operons are very important in bacteria because operons allow the cell to efficiently express the groups of genes whose products are needed at the same time.
which is true of the light reaction of photosynthesis
Hello There!
The correct answer is it produces "ATP"
Answer:
What is true of the light reaction of photosynthesis is that it produces ATP.
Explanation:
Photosynthesis is the conversion of inorganic matter to organic matter thanks to the energy provided by light. In this process the light energy is transformed into stable chemical energy, being the NADPH (nicotine adenine dinucleotide phosphate) and ATP (adenosine triphosphate) the first molecules in which this chemical energy is stored. Subsequently, the reducing power of NADPH and the energy potential of the phosphate group of ATP are used for the synthesis of carbohydrates from the reduction of carbon dioxide.

1. Name TWO contributions made by soil organic matter to the environment.
2. What happens to the pH of the ocean seawater as carbon dioxide dissolves into it?
3. Give TWO relationships between greenhouse gases and heat radiation that negatively affect the globe.
Answer:
1) Binds soil particles into aggregates and improves the water holding capacity of soil.
2) When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
3) Carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming.
Without greenhouse gases in its atmosphere , the Earth would be much colder on average than it is now. Greenhouse gases: absorb energy transferred as infrared radiation from the Earth's surface. release infrared radiation in all directions, which keeps the Earth warm.

What was Pangaea?when did it form and when did it break apart it was
Pangaea was a supercontinent. This was a land mass that included all continental masses on Earth, and it was the last one of this type. There were two other supercontinents after it broke apart, but they were not consisted from all land masses. Pangaea formed in the late Paleozoic era, around 335 million years ago, and it existed until the early Mesozoic until it started to break apart around 175 million years ago. After it broke apart, there were two large continents that were short lived, Laurasia on the north, and Gondwanaland on the south, and from the further breaking apart of these two the modern day continents have formed.

A) people
B) automobile and trucks
C) solar heat from the sun
D) industry and manufacturing
I think the answer is c, because in a city, there is very little natural shade like trees. also, asphalt creates more heat when the sun is directly on it.
Answer: Option C
Explanation:
The heat from the sun is absorbed by the trees and the cooling of the places takes place because of the trees in the area.
But due to the development of the cities there are a lot of building and infrastructure which does not allows the heat to escape and makes the area more hot.
The radiations from the sun is not allowed to escape and due to this the area becomes more heated.

Wally is a planetologist in the future. He discovers a planet similar to Earth that has two major oceans. Ocean A is
very large and looks like it has baseball stitches down its center. Ocean B is very small and has volcanoes all along
one side. Wally needs to predict what the planet will look like far into the future. Which prediction would most likely
come true?
Ocean A will shrink, and Ocean B will get bigger.
Ocean A will disappear, and Ocean B will remain the same.
Ocean A will get bigger, and Ocean B will shrink.
Both Ocean A and Ocean B will remain the same.
Answer:
Option (C)
Explanation:
The divergence of two oceanic plates leads to the expansion of the ocean. The mid-oceanic ridge occurs along the divergent plate boundary, where the magma comes out to the surface of the ocean floor and solidifies. This region experiences more stretching as a result of which the sea floor near the mid oceanic ridge appears like the baseball stitches. This oceans in due course of time becomes large because of the continuous expansion. For example, the Atlantic ocean is rapidly expanding.
On the other hand, the oceans also gets shrink because of the convergence of oceanic and continental plates and convergence of two oceanic plates. They are often marked by the presence of active volcanisms in its adjacent plate. These oceans due to the continuous convergence, leads to the shrinkage of oceans. For example, the Pacific ocean.
Thus, the ocean A will become larger and Ocean B will shrink.
Hence, the correct answer is option (C).

Answer:
B. Two different sperm both fertilizing the same egg
Explanation:
Two different sperm both fertilizing the same egg
Answer: B. Two different sperm both fertilizing the same egg.
Explanation:
Fertilization is a process which involves the fusion of haploid gametes such as a sperm from male and an egg from female to develop a diploid zygote either inside the body of female mate (internal fertilization) or outside the body of female mate (external fertilization).
B. Two different sperm both fertilization the same egg. is the correct option. As only one sperm can fertilize the egg. The sperm brings changes in the external membrane of the egg which prevents the fusion with other sperm.

how to finding life in extreme environment on Earth support the idea that life exists elsewhere?
Very often the critics of the idea that there's life on other planets tend to argue that in order for the life to develop there has to be certain right conditions, like water, temperature that is not extreme, oxygen etc. But with the greater examinations of the most extreme places on the planet, it has been shown and proved that life can exist in places that were never thought it is possible, in fact, the only places on the planet where there's no life is inside the volcanoes. Organisms have been discovered that live at places where there's no oxygen, deep bellow the ice, at temperatures that are significantly higher than those on the surface of Earth, or at places where there's no water. This proves and supports the idea that life is able to find its way to survive in incredibly cruel environments, so there's no reason why it would not be able to develop on other planets or moons in the universe.

what is the largest population that an ecsystem can support over time?
Answer:
Explanation:
The largest number of individuals of a species that an environment can support and maintain for a long period of time.
The largest population that an ecosystem can support over time is known as the carrying capacity.
Carrying capacity is defined as the maximum number of individuals of a particular species that an ecosystem can sustainably support without degrading the natural environment and its resources. This concept is central to the study of population ecology and is influenced by a variety of factors, including available resources such as food, water, and shelter, as well as environmental conditions, disease, and the presence of predators.
When a population within an ecosystem grows, it will eventually reach a size that the resources can no longer support. At this point, the population size will stabilize around the carrying capacity, or it may experience a die-off until the population size is back within the limits that the ecosystem can support. The carrying capacity is not a fixed number; it can change over time due to changes in the ecosystem, such as climate change, human activities, or the introduction of invasive species.
Mathematically, carrying capacity (K) can be represented in the logistic model of population growth, which is given by the equation:
[tex]\[ \frac{dP}{dt} = rP \left(1 - \frac{P}{K}\right) \][/tex]
where:
- [tex]\( \frac{dP}{dt} \)[/tex] is the rate of change of the population (P) over time (t),
- [tex]\( r \)[/tex] is the intrinsic growth rate of the population,
- [tex]\( P \)[/tex] is the current population size, and
- [tex]\( K \)[/tex] is the carrying capacity of the environment.
As the population size (P) approaches the carrying capacity (K), the growth rate slows down, and the population levels off. If the population exceeds the carrying capacity, the term [tex]\( \left(1 - \frac{P}{K}\right) \)[/tex] becomes negative, leading to a decline in population size until it returns to or below the carrying capacity.

Sharon puts a large pot of water on the stove to boil pasta. Then she starts to make a tomato sauce. When the sauce is cooking, she looks at the pot of water and thinks the water level is much lower than it was. How does this diagram of part of the water cycle help Sharon explain what happened to the pasta water?
A .Energy from the stove heats the water, causing the water molecules to move faster and collide harder. This causes the water to change from liquid to gas.
B. As the water heats up, the water molecules begin to move faster and collide harder. This causes them to gain energy from the sun, and change from liquid to gas.
C. As the water heats up, the water molecules begin to move faster and collide harder. This causes them to release energy into the air, and change from gas to liquid.
D. Energy from the stove heats the water in the pot, causing the water molecules to move faster and collide harder, and eventually it causes the water to change from gas to liquid.
Maria has been making weather observations for the last couple of days. She made the following notes on the cloud coverage: “Monday: Sky is clear, no clouds. Tuesday: Sky is partly cloudy, large fluffy clouds.”
Which understanding about the water cycle can help Maria explain the differences in the cloud coverage?
A .More water evaporated from the land to form the clouds on Tuesday.
B. More water evaporated from the land to clear away the clouds on Monday.
C. More water vapor condensed in the atmosphere on Tuesday to form the clouds.
D. More water vapor condensed in the atmosphere on Monday to clear away the clouds
Answer:
1. A
2. C
Explanation:
Hi again!
For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.
What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.
A is the correct answer.
For the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.
C is the correct answer.
I hope I helped! :)
The diagram of the water cycle helps explain the evaporation of pasta water, while understanding the process of condensation in the water cycle can explain the differences in cloud coverage.
Explanation:The correct answer to the first question is A. Energy from the stove heats the water, causing the water molecules to move faster and collide harder. This causes the water to change from liquid to gas. When the water is heated, it evaporates and changes into water vapor, which is a gas. This is an example of the water cycle, where water goes through the processes of evaporation, condensation, and precipitation.
The correct answer to the second question is C. More water vapor condensed in the atmosphere on Tuesday to form the clouds. Clouds are formed when water vapor in the air condenses into tiny droplets or ice crystals. On Tuesday, more water vapor condensed in the atmosphere, resulting in the formation of clouds.
