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:

Foliation 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.

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.

Explanation: it gets weaker because there not as close together

Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.

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.

Answer:

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

gaining modification in their Gene's which helped them to resist that particular pesticide

These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.

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.

Hence, These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.

Answer:

Cause: Earth’s magnetosphere traps radioactive  solar wind particles in bands around Earth → Space travel through the Van Allen  belts is dangerous.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.

Answer:

28% of Adenine

Explanation:

Chargaff's Rule states that A = T and C = G

Because of that, the sample must have the equation:

A + C = T + G

G must have the same amount as C so,

A + .22 = T + .22

Both sides of the equation must equal each other by .50, so .50 - .22 = .28

.28 x 100 = 28%

If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%

The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.

DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.

Chargaff's Rule states that A = T and C = G

Because of that, the sample must have the equation:

A + C = T + G

G must have the same amount as C so,

A + .22 = T + .22

Both sides of the equation must equal each other by .50, so .50 - .22 = .28

.28 x 100 = 28%

Therefore, the percentage of the sample is made up of adenine, A is 28%

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°
