Answer: geologic events like earthquakes and volcanoes that happen at their boundaries
Explanation:
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.
Evidence for plate tectonics includes satellite images of plate outlines, earthquakes and volcanoes at plate boundaries, drilling samples, topographical studies, and the concept of uniformitarianism to infer past tectonic activities.
Explanation:The evidence for plate tectonics comprises multiple observations and scientific data. Satellite images enable us to see the jigsaw-puzzle appearance of tectonic plates, confirming the outlines of the plates. Geologic events such as earthquakes and volcanoes that predominantly occur at plate boundaries offer strong evidence of plate movement. These natural phenomena correlate with fault lines and areas of tectonic stress where the Earth's crust is undergoing deformation. Additionally, drilling into the Earth and studying rock layers can provide direct physical evidence of past and present tectonic activity.
Geologists also use the concept of uniformitarianism to understand plate tectonic activity from the geologic past. They interpret ancient tectonic activity by observing ongoing processes and their impact on the landscape—including mountain building and the formation of rift valleys and ocean trenches. The study of topography and bathymetry also offers insights into the tectonic history of an area, with changes in elevation indicating past plate movements.
Overall, the interplay of these pieces of evidence supports the theory of plate tectonics, explaining the dynamic and continually changing nature of Earth's surface.

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.

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.

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.

why are cat's scared of cucumbers?
Answer:
the cats think its a snake so they going into a defensive reaction
Cats may be scared of cucumbers because they mistake them for predators like snakes, triggering their instinctual fight-or-flight response. The element of surprise also contributes to this fear. Scaring cats in this way can be harmful and stressful to them.
The question of why cats are scared of cucumbers can be explained by combining a few principles of biology and behavior. When a cat encounters a cucumber, it may mistake it for a predator or a snake, both of which pose a potential threat. This sudden appearance triggers a cat's instinctual fight-or-flight response, causing fear and alarm.
Additionally, the surprise element comes into play; cats are not expecting an object to be behind them when they are eating or in a relaxed state. Thus, the unexpected presence of a cucumber (or any object that sneaks into their personal space) can lead to a startled reaction.
It is also important to note that scaring cats with cucumbers or any object can be harmful and stressful to them. It is best for their well-being to refrain from creating these scenarios.

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

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.
