Describe the rock layers shown in Diagram A and any forces acting on the rock.
Answers
The rock in diagram A has three horizons and no force acts on it.
What is a rock?A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.
Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.
In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.

What is a similarity between phases of moon wi2 and wk 4
Answers
The moon has four phases, which happen in a fixed sequence. Each phase lasts one week and takes place as follows:
1st week - New Moon: At this moment, the part of the moon that is illuminated by the sun is not facing the earth. This prevents the moon from being seen.
2nd week - Crescent Moon: Only ¼ of the moon is being lit by the sun and facing the earth. Therefore, we can only visualize a small part of the moon.
3rd week - Full Moon: The face of the moon that is facing the earth is completely illuminated by the sun, which allows this entire face to be visualized.
4th week - Waning moon: Once again, only ¼ of the moon is lit by the sun and facing towards the earth.
The moon does not have its own light, but reflects the light received by the sun, for this reason, we cannot fully visualize the moon.

A rise in __________ released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires __________ energy.
Answers
A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.
Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).
The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
This organelle (sarcoplasmic reticulum) acts to store calcium which is required during muscle contraction.

Think about the methods used to analyze DNA.
Answers
The technology that was used to produce the results illustrated in the image is gel electrophoresis and it is used for separating deoxyribonucleic acid (DNA) fragments.
Gel electrophoresis can be defined as a technology that is used in the laboratory for the separation of mixtures of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or other macromolecules such as proteins based on molecular size and charge.
In gel electrophoresis, an electric current is applied to the deoxyribonucleic acid (DNA) samples so as to create fragments that can be used to compare the various samples of deoxyribonucleic acid (DNA).
The steps involved in gel electrophoresis include the following:
Extraction of deoxyribonucleic acid (DNA).DNA isolation and amplification.Addition of deoxyribonucleic acid (DNA) to the gel wells.Application of an electric current to the gel.The separation of DNA bands based on molecular size and charge.Deoxyribonucleic acid (DNA) bands are stained.Read more: https://brainly.com/question/10413501

Which structure allows
gases and nutrients in
and out of the cell?
A. mitochondria
B. cytoplasm
C. nucleus
D. cell membrane
Answers
The cell membrane allows gases and nutrients in and out of the cell.
The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.
The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:
Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.
Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.
In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.

A significant amount of legislation passed in the 20th century sought to reduce the risk of future economic events like the liquidity crisis

Answers
The policy which would would increase the risk of a liquidity crisis is Banks
being required to store a smaller percentage of depositor funds in their
vaults.
Liquidity occurs when there is an increase in demand and decrease in
supply. Banks usually have a large percentage of depositor funds stored in
their vault to prevent these occurrence.
In situations whereby they store a smaller percentage of depositor funds in
their vaults , it will lead to a liquidity crisis as they won't be able to cater for
