Why are seismic waves considered
mechanical waves?
A. They must travel through a medium, such as
the bedrock of the Earth.
B. They will only travel through empty space.
C. They travel in circles.
D. They do not require a medium.

Answers

Answer 1

Answer:

The correct answer is - option A.

Explanation:

The seismic waves are the waves that are the result of an explosion or the breaking of the rock within the earth. In other words, when these explosions or breaking cause an energy transfer within the earth are seismic waves. Seismic waves require a medium to travel and normally it is the earth.

The bedrock of earth is a great example of a medium for traveling these waves that make it a mechanical wave. Earthquake is the result of such waves.

light-dependent reaction

first stage photosynthesis

Answers

Answer:

light-independent reaction

Explanation:

Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.

The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:

- Carbon fixation of CO2

- Reduction reactions of G3P

- Regeneration of ribulose 1,5-bisphosphate (RUBP).

Answers

C

Explanation:

protons are positive neutrons are neutral and electrons are negative

In an electrically charged particles  protons are positive and electrons are negative.

Neutron has a positive electrical charge?The charge on neutron is zero(no charge). The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another and so atoms are neutral.

Protons have positive or negative?

A proton carries a positive charge and an electron carries a negative charge.so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.

Answers

Explanation:

detach it from or reattach it to the ATP molecule (Brandt). A main reason this is important is because as it was stated earlier, almost all organisms obtain and store their energy through the use of ATP. It is important to note that this energy comes from the energy stored in the bonds of the ATP molecule; therefore, breaking the bonds will release energy and the building of the bonds will require energy. Using this background knowledge, the question can be addressed more thoroughly. Most plants (a fruit in this case) make their own energy through the use of photosynthesis. The basic process of photosynthesis occurs as: light energy (sun) + 6 H2O + 6 CO2 6 O2 + C6H12O6 This is a simplified version of the equation and one must keep in mind that the reaction does not simply occur as written. There are many processes that must take place before the final product, glucose, is produced. Conceptually, photosynthesis is the reverse of cellular…

In shorthorn cattle, color shows incomplete dominance. A red cow has the genotype RR. A white cow

1. Cross a red bull with a roan cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow

Answers

Answer:

red cow would be 50% and the same for a roan cow

Cross a Red Bull with a roan cow. The Punnett Square are

% Red Cow =  25% red

% Roan Cow = 50% roan

% White Cow = 25% white

What is a Punnett square?

A Punnett square is a square with a block that is used to see and describe the offspring of the next generation. It contains both genotypes, dominant and recessive, and then there is a crossing over.

Given that, the red cow has genotype RR

A white cow has the genotype ww.

Heterozygous cattle are called Roan (red and white spotted) (RW).

When RR (red) is crossed with WW (white), it results in a roan color.

RR (red)   x    WW (white) = RW (roan)

Two roan individuals are then mated.

RW    x    RW

RR    RW    RW    WW

Offspring

1/4 RR - Red

1/2 RW - Roan

1/4 WW - White

Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.

Drag is a force caused by air that slows objects down

Friction is a major force that slows the object down, air resistance is a type of frictional force.

What is air resistance?

Air resistance is a kind of frictional force that slows down an object from moving in a particular direction.

During the movement an object has a particular speed for movement, speed depends on how friction works, more friction slows the speed of an object a low friction allows the object to at a particular speed.

Air is a mixture of gases and particles in the atmosphere, these particles create a force during the movement of an object in the air, and these forces decide the actual speed of object movement.

Therefore air resistance is a force that slows the object.

Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA

Answers

Answer:

A. DNA polymerase pairing A with G

Explanation:

Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).

DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.

An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.

DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.

It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).

If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.

This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.

The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.

Thus, the correct option is A.
