How could a change in the size of the walleye pollock population cause an increase in the size of the moon jelly population?
u must have been a change to the birth rate or the death rate in the moon jelly population. Within a population, organisms are always being born and dying. ... zooplankton; a decrease in walleye pollock, leading to an increase in zooplanktonanation:
Final answer:
A decrease in the walleye pollock population can lead to an increase in the moon jelly population due to reduced predation on the jellies' food sources, demonstrating the interconnected nature of marine ecosystem dynamics.
Explanation:
Changes in the size of the walleye pollock population can impact the moon jelly population through a cascading effect in the marine food web. When the walleye pollock population decreases, possibly due to overfishing or environmental changes, their predation pressure on the jelly's prey also lessens. Consequently, with fewer predators consuming their food sources, moon jellies may experience a boom in the food available to them, such as zooplankton, allowing the jelly population to grow.
This demonstrates a fundamental concept in ecology where the populations of predators and prey are interconnected. Fluctuations in one part of the food web can lead to changes in other populations. Examples include the impact of PCB presence on higher trophic levels, the introduction of fish farms affecting local fish species, or how the size of fish can influence their reproductive success. Disruptive events, such as overfishing, can therefore not only affect the targeted species but also have unexpected consequences on ecosystem dynamics.

4. If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of refraction?
15 index ofreaction 21820 and the angle of medence is as degres what's the angle of reaction
16 degrees
32 degrees
48 degrees
64 degrees
Answer: The angle of refraction is 32°
Explanation:
By snell law, we have that:
n₁*sen(θ₁) = n₂*sen(θ₂)
Where n₁ = 1.5
n₂ = 2.0
θ₁ = 45°.
then we want to find the angle of refraction.
1.5*sin(45°) = 2*sin(x)
x = Asin(1.5*sin(45°)/2) = 32°
The angle of refraction is 32.0 degrees
Refractive index and Shell's lawSnell’s Law describes how a ray of light will change direction as it passes from one medium into another, or as it is reflected from the interface between two media.
Snell's law states that:
n1 * Sinθi = n2 * Sinθrwhere;
nA is refractive index of media Aθi is the angel of incidence in media 1n2 is the refractive index of media 2θr is the angle of refraction in media 2Using the formula above
1.5 * sin 45 = 2.0 * sin r
sinr = 1.5 × sin 45/2
r = 32.0 degrees
Therefore, the angle of refraction is 32.0 degrees

Describe the general structure of the monomers
Answer:
The monomer is an amino acid, and I will describe it below. :)
Explanation:
Rubisco is an enzyme found in plants, and its job is to fix carbon. Since we know it is an enzyme, we also know it is a protein since pretty much all enzymes are proteins. The monomer of proteins is the amino acid.
The structure of an amino acid looks like this (see the picture). On one side we have a basic amino group, on the other side we have an acidic carboxyl group. The combination of the amino group and acid group gives us the name amino acid. Also notice that there is the R group. Each amino acid has the same basic structure (with the amino group and carboxyl group), but the unique R group is what gives the particular amino acid its unique characteristics. There are about 20 different kinds of R groups which is why there are 20 different types of amino acids.
So, having a non-polar R group would allow it to interact with a hydrophobic amino acid in another Rubisco molecule.
Monomers are the basic unit of polymers. They are composed of carbon, oxygen, and hydrogen atoms, joint by covalent bonds. There are different monomers which vary in structure, such as nucleotides and amino acids.
-------------------------------------------------------------------
Monomers are the basic unit of polymers. When many monomers join through chemical bonds, through the polymerization process, they form a polymer.
There are many types of monomeric molecules. To name a few, we can mention
Monomer Polymer
Monosaccharide ⇒ CarbohydratesFatty acid ⇒ LipidsAmino acid ⇒ ProteinsNucleotide ⇒ Nucleic acids
Monomers are organic molecules of reduced molecular mass. They are basic units relatively simple, with a defined structure.
Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.
For instance,
Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.Amino acids are monomers composed of a central carbon, one hydrogen atom, one carboxyl group, one amine group, and one R group. The composition of the R group is what makes them different from each other.Every monomer has a free H atom and a hydroxyl group (-OH) in the extremes. When two monomers get together, the H atom and the -OH join to form a water molecule, which is released. The result is a polymer of two monomers and H₂O.

Answer:
It is true that climax communities are stable for a long time, with the same species maintaining their population.
Explanation:
Climax is the final, relatively stable state of successive ecosystems that occurs as a result of shifts, or successions, and to a large extent corresponds to the environmental conditions of a particular area. Climax depends on climatic factors, on local soil characteristics and on human impacts on nature.
Theoretically, the climax community can support itself indefinitely, all its internal components are balanced with each other, and it is in equilibrium with the physical environment.

Researchers are studying lichens growing on trees in a forest ecosystem. At the beginning of the study, the researchers identified twelve lichen species in the forest. Later, a forest fire happened in the study area. The researchers returned to the area and found only six lichen species. What inference is best supported from the researchers observations?
Answer:
Certain lichen species are better adapted to survive forest fires than others.
We can conclude that Initial area of the forest was suitable for lichens whereas the later area was not suitable for lichens.
What are lichens?Lichens do not have vascular tissue like xylem and phloem to carry nutrients and water throughout their thalli like a plant does, nor do they have a waxy coating like plants do on their leaves.
The structure of the lichen incorporates everything in its surroundings. Lichens obtain their water and nutrients from the air and rain that fall on them. A lichen's basic structure is made up of layers of fungus and algae.
If there is already a green algal layer present, cyanobacteria can be found in a layer beneath the upper cortex or in microscopic pockets on top of the upper cortex. The lichen will be dark green, brown, or black in color thanks to cyanobacteria.
Therefore, We can conclude that Initial area of the forest was suitable for lichens whereas the later area was not suitable for lichens.

a. their shorter duration
b. the combination of high winds and flood waters
Selected:c. all of the aboveThis answer is incorrect.
d. coastal storm surges
Answer:
B.) the combination of high winds and flood waters
Explanation:
Hurricanes contain coastal storm surges, high winds, flood waters. Hurricanes also last longer than tornadoes. Hurricanes can last days and maybe even weeks.
The answer would the combination of high winds and flood waters because winds can reach at least 156 mph with a category 5 hurricane. A category 1 hurricane can produce 74 to 95 mph winds. For comparison, an EF0 tornado can produce 65 to 85 mph winds. As for flooding, most of the locations that experience hurricanes are coastal areas, meaning they are situated around an ocean. Since there is a lot more water in the ocean than in a lake, like Lake Michigan or Lake Huron, there is a lot more water that can drown a city. As years pass, hurricanes are getting more and more devastating due to climate changes. More places will get destroyed by hurricanes, high wind, and flood waters.

Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º.
Scarlett's height is 1.65 meters, so the height of the dam is meters.
Answer:
The height of a dam:
h = x + 1.65 m,
x = 90 m · tan 26°
x = 90 · 0.4877
x = 43.90
h = 43.90 m + 1.65 m = 45.55 m
The height of the dam is 45.5 m.
Explanation:
The height of the dam will be "45.55 m". A complete solution is below.
According to the question,
The height of dam,
[tex]h = x + 1.65 \ m[/tex]
