Answer:
1:(D), 2:(D), 3:(D)
Explanation:
1) When a rock is exposed to heat and pressure, it becomes a metamorphic rock. This is correct, because this is the process that forms a metamorphic rock.
2) A rock becomes sediment through weathering and erosion. In this question, they are not asking you to explain the process of sedimentary rock formation, they are asking you how a rock becomes sediment. The process of weathering and erosion breaks down a rock, and turns that rock into smaller peices, which therefore, through the process of compaction and cementation forms a sedimentary rock.
3) A fern is a land plant. It is not found in the sea and there is not enough information given to tell whether or not the area was hot or cold. This leaves us with D. We can tell that this fossil is a land fossil because ferns do not grow in the ocean.
Hope I could help, and best of luck!

Rationale:
Human waste is a large problem and the government is trying to stop the public from disposing of it.
Which Sub-Problems does this criteria address?:
Globally, almost 80 percent of the world's wastewater flows back into the ecosystem without proper treatment. This means that almost a quarter of people drink water contaminated with human waste, according to United Nations Water. That incubates deadly diseases, including cholera, dysentery, typhoid and polio.
Criteria:
Oil
Rationale:
Oil is needed for just about everything but it is very costly when it comes to the environment.
Which Sub-Problems does this criteria address?
Oil spills have a devastating effect on the environment, ruining habitats and killing the organisms that live there by sticking to them, destroying their food sources and poisoning them. Additionally, oil hurts the economy by harming the fishing industry, as well as other trades that rely on the ocean.
Explanation:
What evolutionary advantage might on/off signaling have over this continuously variable kind of signaling?
Answer:
Hello the options to your question is missing below are the missing options
A threshold to cause a signal is lower than in graded potentials. Graded potentials can cause a strong but single depolarization signal.
The speed of propagation is much faster as depolarization in one location causes depolarization in the neighboring ones.
Propagation of the on/off signals requires less ATPATP because the neighboring locations can depolarize each other.
The on/off signal may be propagated over long distances without any decay. Therefore, the signal is reliable.
The power of the stimulus does not matter once it triggers the signal. Therefore, different stimuli may cause the desired response.
Answer :The speed of propagation is much faster as depolarization in one location causes depolarization in the neighboring ones.
Propagation of the on/off signals requires less ATPATP because the neighboring locations can depolarize each other.
Explanation:
Some of the evolutionary advantage that on/off signaling have over this continuously variable kind of signaling are :

What type transporters are used by mitochondria to shuttle ATP and ADP through mitochondria and cell?
Answer:
The correct answer is ATP/ADP transporter.
Explanation:
Mitochondria are the cellular compositions, considered as the driving force of the cells. Each day, ATP is required by living beings to energize all of the cellular activities. Muscle contraction, nerve impulses, protein synthesis, and DNA replication are some of the important procedures, which depend upon ATP supply.
As the only small concentration of ATP is present within the body, there is a need to produce it from the expended product ADP and phosphate with the help of the complex of enzyme, known as ATP synthase situated within the mitochondria. For the ADP to reach the enzyme and for refueling of the cell by the product ATP, each molecule is required to pass through an impermeable lipid membrane, which envelopes the mitochondria. For this, the mitochondrial ATP/ADP transporter takes part to transport ATP out of the mitochondria and ADP within the mitochondria.

Convection currents for weather start from when the Sun heats up the air. true or false
Answer:
True.
Explanation:
Convection currents for weather start from when the sun heats up the air because convection. Current is a form of heating where the lighter warm or less dense material rise above the denser or more dense material because the more dense materials cool and sinks downward giving rise to sea breeze. This convection current lead to circulation pattern on Earth

When a mitochondrial chaperone helps a mitochondrial matrix protein into the matrix by biased diffusion, the chaperone is said to be acting as ______.
a. Brownian motion
b. biased diffuser
c. Brownian ratchet
d. misratchet
e. unbiased diffuser
Answer:
c. Brownian ratchet
Explanation:
Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.
The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.
The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.

is when the lead male and female are given preferential treatment to resources such as food and potential mates.
Answer:
Dominance hierarchy
Explanation:
Dominance hierarchy may be defined as a type of a social hierarchy which arises when the members of a social group interacts and create a ranking system in the society. The members compete for access to the to limited resources as well as mating opportunities.
It is the ranking system behavior in the nature where the lead or the main male and females are provided preferential treatment to the food resources and potential mates.
If the last pair reflects whether the organism is a male or female, which would the organism be?
Complete question:
There is a karyotype in this question, which is missing. You will find it in the attached files.
Answer:
The individual is a male.
Explanation:
In mammals, sex is determined by a pair of sexual chromosomes. Sexual chromosomes in humans and other mammals are X and Y. The females are represented by the combination of two X chromosomes, while males are represented by the combination of an X chromosome with a Y chromosome. This is, females are XX, and males are XY. When looking at the sexual pair of chromosomes in a karyotype, you can figure out which is the individual´s gender by comparing their sizes. The X chromosome is much bigger and longer than the Y chromosome.
In the shown karyotype, the last pair represents the sexual chromosomes. You can see that one of them (the one on the left) is long and express a sort of J shape, while the other chromosome (on the right) is very short and small. According to what we previously mentioned, the X chromosome is the long one on the left, and the Y chromosome is the short one on the right. This is a male individual.
Sex chromosomes are the central determinant that defines the sex of an individual. By analyzing the karyotype one can conclude the sex chromosomes and the autosomes.
The correct answer is:
The individual is male.
Reason for the answer:
In organisms like mammals, the sex of an individual is determined by sex chromosomes. Humans and many other mammals have two sex chromosomes X and Y.The females have two X chromosomes(XX), while males have one X and one Y chromosome (XY).By studying karyotype one can distinguish among the X and Y chromosomes. The X chromosome is bigger than the Y chromosome.The karyotype provided in the question represents sexual chromosomes. The chromosome present on the left is large and is J-shaped which represents the X chromosome, while the chromosome present on the right is small and depicts the Y chromosome.Therefore, the given Chromosome is the Y chromosome and represents a male chromosome.

Explanation:
- Pain, swelling, or redness where the shot was given
- Mild fever
- Chills
Feeling tired
Headache
- Muscle and joint aches"
.
A lot of us can probably state from experience feeling at least a few of these symptoms with
vaccines. I just got my flu shot on Sunday, and I personally experienced pain at the site of the shot,
tiredness, and muscle and joint aches. (These symptoms were mild and completely worth reducing
the risk of contracting and spreading influenza this fall and winter.)
What's really cool is these symptoms actually serve as a sign that our immune system is at work.
Explain how these mild symptoms following a vaccine indicate our immune system is working
properly. Although we often think of how vaccines affect the third line of defense through the
creation of memory cells and production of antibodies, consider what you learned in the previous
chapter on the second line of defense and how this relates to the mild symptoms following
vaccination.
8 facts about the Geosphere
Facts:
The Geosphere is basically the insides of the earth so breaking it up into eight parts will be based on each section of it.
1. The crust is the top layer of the Earth, it consists of the water and land we see. It is a shell that lays atop or covers the Upper mantle piece.
2. The mantle is a layer between the crust and core, Earth's mantle is a rocky shell that is roughly 2,900km thick and is 84% of Earth's volume.
3. The Geosphere is the solid part of the Earth that consists of rock, soils and sediments on the surface of the Earth.
4. The core is the innermost layer of the Earth and is up to 6371km from the surface of the Earth, it consists of Nickel and Iron and are seen as main components of it.
5. The outside of the core is known as the molten core due to it mainly being liquid metal from the heat and the inner portion of the core known as the solid core.
6. Another name or term given to the Geosphere is called the lithosphere, depending on the definition they both mean the same thing but are still argued by scientists.
7. The Geosphere is in constant motion due to the tectonic plates. These plates are what causes earthquakes ,volcanoes to erupt and even tsunamis.
8.There are eight major tectonic plates making up the earth's geosphere. They are constantly moving, but usually only a few centimeters each year, this is known as continental drift.

Describe the osmotic regulation strategies of marine fish
Answer:Water will diffuse into the fish, so it excretes a very hypotonic (dilute) urine to expel all the excess water. A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. It actively excretes salt out from the gills.
