Answer:
In a wetland ecosystem:
1- Indicator species: turtles
2- Keynote species: freshwater crayfish
Explanation:
A wetland is an ecosystem either covered with water or saturated with water. Examples of plants living in wetland ecosystems include water lilies lotus, trees (e.g., swamp she-oak), mosquito fern, eelgrass (Vallisnaria spiralis), etc. Examples of animals living in wetlands include dragonflies, mosquitoes, alligators, salamanders, snakes, turtles, grouse, plover, etc. Alligators and freshwater crayfish can be considered keystone species because they are fundamental and their presence defines wetland ecosystems (without these species, wetlands would be dramatically impacted). Moreover, turtles can be considered indicator species because their abundance and distribution in a wetland is an indicator of environmental conditions. These animals (turtles) carry around different organisms (e.g., algae) that are eaten by other species (e.g., fish), and thus contribute to the homeostasis of the ecosystem.
Why does warm air rise
Answer:
When we heat air, the molecules jiggle and zip around faster, which causes them to spread out. When a mass of air takes up more space, it has a lower density. ... Warm air rises when it's surrounded by cold air because of its lower density.
Explanation:
hope this helps :)
Answer:
SAMPLE: When we heat air, the molecules jiggle and zip around faster, which causes them to spread out. When a mass of air takes up more space, it has a lower density. ... Warm air rises when it's surrounded by cold air because of its lower density.
Explanation:
What this means is that when it is hot outside, molecules move faster and faster. This propels the molecule up since the molecule cannot handle low density. This is because when molecules occupy space and a molecule is moving very fast, it needs as much space as possible to move.

You are a tomato farmer whose crops are threatened by a persistent species of beetle. Each year, you spend large sums of money for pesticides to protect your crops. A biotechnology company introduces a new strain of tomato plant that produces a natural pesticide, making it resistant to the beetle. By switching to this new strain, you could avoid both the beetle and the chemical pesticides traditionally needed to fight it.
Answer:
This question is incomplete, the complete question is:
Do you switch to new plant? Why or why not?
Yes, because it would help me get rid of the beetle naturally and save cost for purchasing pesticides.
Explanation:
This question is describing the genetically modified strain of tomato plant introduced by a biotechnology company. The GM tomato plant naturally repels the beetle pest that has been threatening the tomato planted by a me, who is the farmer.
However, the farmer has been spending a huge sum of of money for pesticides to protect his crops. Hence, I would opt to switch to this new strain, so I could avoid both the beetle and the cost of chemical pesticides traditionally needed to fight it. That is, by using the Genetically Modified strain of tomato, I can naturally get rid of the beetle pest and simultaneously save the cost of procuring a control measure (pesticides).

7. If any type of rock experiences intense heat and cools it changes into?
Answer:
Metamorphic rock occurs when you take any other type of rock and put them under and , and they twist and meld together. ... If any type of rock experiences intense heat and cools it changes into rock.
Explanation:
Answer: Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale.

In what ways does carbon enter the hydrosphere?
Answer: When oxygen is present, aerobic respiration occurs, which releases carbon dioxide into the surrounding air or water. Otherwise, anaerobic respiration occurs and releases methane into the surrounding environment, which eventually makes its way into the atmosphere or hydrosphere.

Answer:
Coral Bleaching
Explanation:
"When water is too warm, corals will expel the algae living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality."

Which parts of the water cycle the water molecules to give away heat energy?
Answer:
evaporation i think but im not sure
Explanation:
Answer:
condensation
Explanation:
Precipitation, runoff, infiltration, and ground water. Is the source of energy that drives earths water cycle. The sun. As heat energy was added to the water, it changed states from. A liquid to a gas. This gas is called water vapor. As more energy is added to the water, the water molecules move.

Explanation:
Answer:
The main focus should be equally on a vaccine and on how effective medical supplies are so we can distribute the most effective preventative measures and hopefully reach herd immunity.
Cheetah have evolved a much higher lung capacity,why
Cheetah need a large lung capacity because they consume a lot of oxygen while sprinting.
Answer:
Cheetahs have evolved a much higher lung capacity than humans; it helps provide oxygen to all the muscles in the body and allows them to run very fast. ... In this case, it is not because they run fast but because they have a large body and must be able to take up oxygen in accordance with their body size.
6. Cellular respiration refers to a process where energy is harvested from glucose or food. What environmental component is necessary for this process to occur? a) water b) carbon ) oxygen d) mtDNA
Answer:
Cellular respiration is the aerobic (oxygen requiring) harvesting of energy from food molecules by cells. Cells get energy from glucose when in an exergonic process, The chemical energy of the bonds in glucose is released and stored in the chemical bonds of ATP.

A transformer in a neon sign contains 20 truns in the primary coil and 80 truns in the secondary coil. Which is greater- the output voltage or the input voltage?
Answer:
The output voltage is greater.
Explanation:
The turns ratio is directly proportional. Vs= Vp X (ns/np)
In this neon sign xformer example it is 80/20 or 4
So secondary voltage for 120 volt primary/line voltage = 480 volt secondary volts.
This is practical in a neon sign as it takes more voltage to start the neon gas excitation.
The output voltage is greater.
Calculation of output voltage:Since A transformer in a neon sign contains 20 turns in the primary coil and 80 turns in the secondary coil.
So here turns ratio should be directly proportional. Vs= Vp X (ns/np)
So, In this neon sign former example it is 80/20 or 4
Thus, secondary voltage for 120 volt primary/line voltage = 480 volt secondary volts.

a) based on the signaling model shown in figure 1, describe the role of molecule B
Answer: There are two kinds of communication in the world of living cells. Communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling. An easy way to remember the distinction is by understanding the Latin origin of the prefixes: inter– means “between” (for example, intersecting lines are those that cross each other) and intra– means “inside” (like intravenous). Chemical sign
Explanation:
Cell communication can either be intracellular or intercellular. The given image represents the transduction steps of the BREC.
In the given image, molecule B represents the VEGF.
VEGF is known as Vascular endothelial growth factor, which is a signaling protein that promotes the growth of new blood vessels.
The growth factor in the given image binds to the active site of BERC and is also associated with the regulation of angiogenesis.
VEGF receptor signal transduction is the master regulator of angiogenesis.
Therefore, in the given image, molecule B represents VEGF factors.

Explain why the pulse rate changes during and after exercise. Important words to use are muscle cells, exercise, energy, glucose, oxygen, blood, and cellular respiration.
Answer:
The pulse rate changes during exercise because when we do exercise the demand for oxygen in body is very high as compare to the supply from the environment. To complete the demand the plus rate changes . when we exercise heavily our muscle cells lacks oxygen and respire anaerobically in which glucose broke down into 3 carbon molecule called Pyruvate .
