Answer:
Metamorphic, Sedimentary, and Igneous
Explanation:
Igneous rocks can melt and solidify again, forming another igneous rock. Igneous rocks can also change into sedimentary rocks or metamorphic rocks. Hope this helps!!
Igneous rocks can form intrusive, extrusive, and metamorphic rock.
Intrusive rocks: These form when magma cools and solidifies beneath the Earth's surface. The slow cooling allows for the growth of large mineral crystals. Examples of intrusive igneous rocks include granite and diorite.
Extrusive rocks: These form when lava or volcanic ash cools and solidifies on the Earth's surface or in shallow underground chambers. The rapid cooling doesn't allow much time for crystal growth, resulting in fine-grained textures. Examples of extrusive igneous rocks include basalt and obsidian.
Metamorphic rocks: Igneous rocks, both intrusive and extrusive, can undergo changes in texture and mineral composition due to high temperature and pressure over time. These transformed rocks are called metamorphic rocks. Examples include gneiss and marble.

If a rock was determined to be around 3.9 billion years old how much Potassium 40 would be left in that rock sample? (Percentage of Potassium 40)
What percent of potassium-40 remains undecayed in a rock that is 3.9 billion years old? The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.
How could life on Earth change if both Carbon Dioxide and Ozone levels began to decrease? Describe at least two ways life would be impacted if this change were to occur.
Answer:
Increase occur in skin diseases and decrease occurs in the Earth's average temperature.
Explanation:
If both Carbon Dioxide and Ozone levels began to decrease, increase occur in skin diseases and decrease occurs in the Earth's average temperature. The decrease in ozone levels allows more UV radiation to reach the Earth's surface which lead to various diseases such as skin cancer, cataracts, and weakened immune systems. The atmospheric carbondioxide gas is responsible for the increase of surface temperature by trapping reflected solar radiations so decrease in carbondioxide concentration will leads to lower surface temperature.

An animal that does not have the traits to adapt to its surroundings will?
Explanation: If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.

In a biological reaction involving an enzyme, what does the substrate bind to? the active site of another substrate the inactive site of an enzyme the inactive site of another substrate the active site of an enzyme
Answer: The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction. To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. ... The products then leave the active site of the enzyme.

Answer:

How can an impulse be stopped?
Answer:
The impulse is stopped dead if an action potential cannot be generated.
Explanation:
The neurotransmitter binds with receptors on the other neuron. -If the K+ channels open, the neuron membrane becomes hyperpolarized, and inhibition occurs. The impulse is stopped dead if an action potential cannot be generated.
I dont understand what they are asking please help!!
Answer:
"Phenotype" would mean the two letter combination of traits that make up this trait. For example, heterozygous would be something like "Cc", with the "C" representing a dominant trait and "b" representing a recessive trait.
In this case, the answer would look something like "CC", though I'm not sure the exact letters this question is using. Good luck!

During the retreat of a glacier, pebbles and bare rock that were under the sheet are exposed to the air. What is likely the next event to occur?
( don’t mind the blue dot )
The retreat of a glacier, pebbles and bare rock that were under the sheet are exposed to the air. Thus, option D is correct.
Why, explain brefly?it’s cause About 200 years ago, the glaciers started melting, which scientists call "glacial retreat."
With the retreat of the glaciers, ridges of rock and debris called moraines remained.
Moraine is little more than bare rock and no plant life can exist on it until the first stages of succession begin.
Thus, option D is correct.

8. What resistance would produce a current of 350 amps with a potential difference of 2,500 volts?
The resistance that would produce a current of 350 amps with a potential difference of 2,500 volts is 7.1 Ω.
What is Resistance?Resistance may be defined as a type of opposition that a substance offers to the flow of electric current. In a more simple sense, it may be understood that anything which restricts the flow of electric current is known as resistance. It may be represented by R.
According to the question,
Current = 350 amperes.
Potential difference = 2500 volts.
Now, according to the formula of potential difference.
Potential difference = Current x Resistance.By modifying the above formula, we get,
Resistance = Potential difference / Current.= 2500 volts / 350 amperes = 7.1 volts/amperes.
Therefore, the resistance that would produce a current of 350 amps with a potential difference of 2,500 volts is 7.1 Ω.
