2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?
Answer:
if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)
Explanation:
The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.
Litostatic pressure originates from the weight of materials in the interior of the crust.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.
There are different types of metamorphism.
Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.
Classification of the metamorphic rocks according to their structure:
GranulationRecrystallizationMetasomatismMassiveFoliationFoliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.
According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.
If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.
What is a foliation?Foliation on a rock means continuous multi layering on a metamorphic rock.
These layers can be thin as a sheet of paper.
Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.
Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

What does a model of the carbon cycle show?
A. The amount of Earth’s carbon is constant.
B. The amount of Earth’s carbon cannot be determined.
C. The amount of Earth’s carbon decreases.
D. The amount of Earth’s carbon increases.
I think its A
Answer:
Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year.
The model of the carbon cycle determines the amount of earth's carbon is constant. Thus, option A is correct.
Carbon is the element that is responsible for the major life forms on earth. The conversion of carbon in varying life forms and the reservoir is given by the carbon cycle.
What is the effect of the carbon cycle on the amount of carbon?The carbon cycle is operated for the analysis of the conversion of the carbon in different states and life forms in the earth.
The conversion results in the change in the state of the carbon and its concentration in different constituents.
The earth is the reserved closed system and is consisted of a fixed amount of elements.
Thus, the amount of carbon in the earth is constant in the model of the carbon cycle. Thus, option A is correct.

Which of the following is not a principle of natural selection?
Answer: The last one on the bottom i'm in biology
The statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others. So, the correct option is D.
What do you mean by Natural selection?Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.
The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.
Therefore, the statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others.

Tim does not need to factor his amino acid consumption into the total protein intake because they are components of protein, not full protein
Answer:
Yes.
Explanation:
Yes, amino acid can not be factor or broken down because it is the smallest unit of proteins. Proteins are made up of about 20 small amino acids. Proteins can be factor into amino acids but amino acids can't be factor into proteins because proteins are made up of amino acids but the amino acids does not formed from proteins so that's why Tim does not factor his amino acid into total protein.

Peter is complaining of stomach pain and constant hunger as he was diagnosed with a worm infection.
Peter feels hungry because the tapeworm is absorbing food from his intestine as tapeworm begins to feed off your body's nutrients to grow once it invades the body.How tapeworm infection occurs?Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae.When tapeworm hatches and attaches itself to your intestine, it starts feeding off body's nutrients causing increase in apatite (hunger increases).It grows by reproducing proglottids ( chain looking body part) and the cycle continues.Planaria upon causing infection feeds on blood cells hence can not cause apatite.Leech and marine worm can not invade the body like tapeworm and planaria.To learn more about tapeworm infections:

A ray of light is passing through a medium making an angle of 45°. If the
refractive index of the medium is 1.4, calculate the angle of refraction. [Ans: 30°)
Answer: By Snell's law, we can see that the angle of refraction is 30.34°
Explanation:
Snell's law says that:
If a ray in a medium of refractive index n₁, insides with an angle θ₁ in another medium with refractive index n₂, then the angle of refraction θ₂ is given by:
n₁*sin(θ₁) = n₂*sin(θ₂)
We know that:
The incidence angle is 45°, then: θ₁ = 45°
We can assume that the first medium is air, then n₁ = 1
The refractive index of the other medium is 1.4, then n₂ = 1.4
Replacing these in the Snell's law equation we get:
1*sin(45°) = 1.4*sin(θ₂)
Now we can solve this for the angle of refraction:
sin(45°)/1.4 = sin(θ₂)
Asin(sin(45°)/1.4 ) = Asin( sin(θ₂)) = θ₂ = 30.34°
So the angle of refraction is 30.34°

Explain the unique information trace fossils and coprolites can help scientists infer about an organism
They're trace fossils, not animal bodies. This coprolite can reveal an animal's diet. Scientists can determine what animal dropped coprolites based on its shape, size, and location.
What are coprolites?Fossilized feces are known as coprolites. Because coprolites provide information for the animal's behavior rather than its shape, rather than being considered body fossils, they are instead categorized as trace fossils.
A coprolite can provide researchers with information about an animal's nutrition. Scientists are able to determine the species of animal that may have been responsible for the droppings by analyzing the shape and size of the coprolites as well as the location where they were discovered.
Because coprolites have a propensity to deteriorate so quickly, we only find them very infrequently. They are the marine species that are found the most frequently. The presence of coprolites in fish and reptiles is very common.

What is a resistance gene?In order to survive, bacteria can create mechanisms known as resistance against antibiotics and antifungals. The germ's resistance mechanisms are determined by the specific proteins that DNA instructs the germ to produce. Many different forms of resistance genes can be found in bacteria and fungi.
Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.
