which of the following correctly orders the zone of depths in a lake from shallowest to deepest?
A. profundal, littoral, limnetic
B. Littoral, profundal, limnetic
C. Limnetic, littoral, profundal
D. Littoral, limnetic, profundal
Answer:
D. Littoral, limnetic, profundal
Explanation:
The level of water bodies like ponds and lakes are divided into different zones from top to bottom and side to side. The Littoral zone starts from the dry land that moves in a downward direction towards the open water. There are lots of nutrients and minerals in this zone. Insects, small fish, and zooplankton live in this zone. The limnetic zone starts after the littoral zone ends. It is the part of the pond which receives the sunlight. Algae and other plants live in this zone because the level of oxygen is high in this area. The profundal zone is located where the sunlight does not reach. The population of fish is very low in this zone.
Answer:
Littoral, limnetic, profundal

How does a scientist compare the age of a rock with other rocks
Answer:
They can use radioactive dating
Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

Which features are usually associated with karst topography?
A. Caves and sinkholes
B. Lakes and wetlands
C. Mountains and valleys
D. Plains and plateaus
A. Caves and sinkholes are usually associated with karst topography.
How Karst topography is formed?Karst topography is formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. As water flows through these rocks, it dissolves them, creating underground cavities and channels.
Over time, the ground above these cavities can sink, forming sinkholes. The dissolved rock can also create caves and other unique features such as natural bridges, disappearing streams, and springs.
Karst topography is a type of landscape that is characterized by distinctive landforms and features that are formed by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum.
These rocks are highly susceptible to chemical weathering, which is the breakdown of rocks and minerals through chemical reactions. The process of chemical weathering dissolves the rocks, leaving behind distinctive landforms and features.
Overall, karst topography is a unique and fascinating landscape that is created by the dissolution of soluble rocks. The distinctive features of karst topography, including caves, sinkholes, natural bridges, disappearing streams, and springs, make it a popular area for exploration and study.
However, the hazards associated with sinkholes and other features of karst topography also make it important to be aware of the risks when living or traveling in these areas.

Please help im being timed Should a marine scientist automatically assume a study from a corporation has bias? Why or why not?
Answer:
Yes
Explanation:
It's safe to assume this because it is the best way to make sure that your sources are reliable and valid.
A marine scientist should not automatically assume that a study from a corporation has bias. This is because there are various factors that could affect the findings of a study, and not all studies from corporations are biased.
What is bias?Bias is the tendency to favor one view, person, or result over another, especially in an unfair or prejudiced way. It can be conscious or unconscious, and it can manifest itself in different ways.
When conducting scientific research, bias is a problem because it can lead to flawed conclusions, which can have negative consequences for the environment or the public.
A marine scientist should carefully evaluate any study, regardless of the source, to determine if it is scientifically rigorous and unbiased. They should look for potential conflicts of interest, analyze the methodology used, and scrutinize the data and results presented.
If they detect any signs of bias, they should report them and try to work with the researchers to correct them or address any concerns. However, if they find that the study is scientifically sound and unbiased, they should acknowledge and use the results in their own work, since these can be valuable for the scientific community.
In conclusion, while it is important to be vigilant against bias in scientific research, a marine scientist should not automatically assume that a study from a corporation is biased. Instead, they should carefully evaluate the study to determine its scientific merits and potential biases, and report their findings accordingly.

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?
Answer:
The bacteria forms new kind of cells to adapt to a new environment. This adaptation is under tight genetic control, involving the expression of multiple genes.
the bacteria need to adjust their enzyme levels in order to quickly benefit from the nutrient mix that is currently available in the surrounding.
If the living environment undergoes a sudden change, the bacterium's own production of proteins has to fulfill these changes in an effective way.

Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.
What is independent variable?The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.
The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.
The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.

The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label A? an arrow pointing from A to a formation of trenches and Island Arcs, an arrow pointing from B and C to an Oceanic Spreading Ridge, and an arrow pointing from D to a trench. © 2016 US Department of the Interior; US Geological Survey Divergent boundary zones Convergent boundary zones Plate boundary zones Transform boundary zones
Answer:
The label A corresponds to Convergent boundary zones
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped volcanic islands, the island arches. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.

Convergent boundaries
