This map shows the counties in Montana that are prone to dam failure. If you were in charge of flood control in Montana, where would your biggest areas of concern be? What other data would you collect about these areas or about local weather patterns to help you make a flood-control plan for the state?
Answer:
The focus would be the western side of the state and several counties in the central part of the state because there are many high-risk dams in these areas. Knowing what communities and structures are located around these dams, the average precipitation rate, and projected rainfall totals would be helpful in designing a flood-control plan. Knowing the age and condition of each dam would be important for setting priorities in the plan.

if epigenetic changes take place above the level of the genome , what would be an example of a change at the level of the genome ?
Answer:
epigenetics chamges take place.
Epigenetics is the examination of the way cells manipulate gene interest without converting the DNA series." Epi-"approach on or above in Greek, and "epigenetic" describes elements past the genetic code.
Epigenetic changes are adjustments to DNA that modify whether or not genes are grown to become on or off. These adjustments are connected to DNA and do now no longer alternate the series of DNA constructing blocks. Within the entire set of DNA in a (genome), all the adjustments that modify the interest (expression) of the genes are referred to as the epigenome.
Because epigenetic changes assist decide whether or not genes are grown to become on or off, they affect the manufacturing of proteins in cells. This law facilitates making sure that everyone produces the handiest proteins which might be essential for its function. For example, proteins that sell bone boom aren't produced in muscle cells.
What is the epigenetic pattern?Patterns of epigenetic change range amongst individuals, in one-of-a-kind tissues inside an individual, or even in one-of-a-kind cells inside a tissue. Environmental influences, together with a person’s food plan and publicity to pollutants, can affect the epigenome. Epigenetic adjustments may be maintained from cell to as cells divide and, in a few cases.
Hence concluded that Epigenetics changes and causes cancers, by changing the genome, epigenome, or both.

fault generally occurs at a transform boundary. O A. normal OB. strike-slip O C. thrust O D. reverse
Answer: Read the question carefully
TRANSFORM BOUNDARIES: B. Strike-Slip
Explanation:
A reverse fault happens at convergent boundaries.
A normal fault happens at divergent boundaries
Hope this helps :)
The fault that generally occurs at a transform boundary is a strike slip. Therefore, option B is correct.
What are transform boundary and strike-slip?A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally in opposite directions. Transform boundaries are characterized by shallow and frequent earthquakes. The most famous example of a transform boundary is the San Andreas Fault in California, which marks the boundary between the Pacific and North American plates.
"Strike-slip" is a type of fault that occurs along a transform boundary, where two tectonic plates are sliding horizontally past each other in opposite directions. In a strike-slip fault, the movement is primarily horizontal and the rocks on either side of the fault move past each other parallel to the strike (or direction) of the fault. The San Andreas Fault in California is a well-known example of a strike-slip fault.
Hence, option B is correct.

Thanks:)
Answers:
Here are some fact about sharks that i found cool
#1
Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey
#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

In this metabolic process, the enzyme RNA polymerase binds RNA nucleotides (the substrates) together by catalyzing the formation of a bond between the backbone sugar of one nucleotide to the backbone phosphate of another nucleotide. Name the metabolic process that bonds RNA nucleotides together
Answer:
TRANSCRIPTION
Explanation:
Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.
RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.
In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.

b
They can interbreed with wasps and increase species diversity.
c
They can colonize wasp nests without being detected.
d
They are mistaken for wasps and avoided by predators.
Answer:
D they are mistaken by wasps
The most likely explanation for why some species of hover flies resemble wasps in body coloring and shape is that they are mistaken for wasps and avoided by predators (Option D).
What is adaptation?Adaptation refers to the process of change in an organism's traits or characteristics over time in response to environmental pressures such as competition, predation, or changing resource availability. Adaptations can be physical, physiological, or behavioral, and they can help an organism to better survive and reproduce in its environment. For example, an organism that lives in a dry and arid environment might develop adaptations such as a deep root system to tap into subterranean water sources or a reduction in body size to reduce water loss through respiration.
Adaptations can occur through natural selection, where traits that are advantageous for survival are more likely to be passed on to future generations, or through other mechanisms such as genetic drift or mutation.

thermosphere
Answer: thermosphere
Explanation:
The layer of Earth's atmosphere most strongly affected by conditions on the sun's surface is the thermosphere.
What is thermosphere?The thermosphere is the highest layer of the Earth's atmosphere, extending from about 90 km to 600 km above the Earth's surface. It is the layer where the majority of ultraviolet and x-ray radiation from the sun is absorbed and where auroras occur. The ionosphere, a part of the thermosphere, is where the sun's solar wind and magnetic fields have the strongest impact on the Earth's atmosphere, creating the Northern and Southern Lights.
In comparison, the mesosphere, stratosphere, and troposphere are lower layers of the Earth's atmosphere that are not as directly affected by conditions on the sun's surface.
