Answer:
c. Compression.
Explanation:
Compression is the primary way from which folded mountains are formed. Fold mountains are created where two or more of tectonic plates of earth are pushed together. Due these collision, compressing boundaries and rocks are folded into rocky hills, mountains, and entire mountain ranges. Fold mountains are formed through a process called orogeny which is an event that leads to both structural deformation of the Earth's lithosphere at the margins of convergent plate.

Nonmetals are defined as elements that generally cannot
conduct _____
and are poor conductors of heat.
Answer:
they can not conduct electricity
Non-metals are defined as elements that generally do not conduct electricity and are poor conductors of heat.
What are elements?
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Cell theory defines the cell being the fundamental unit that is the structural and the functional basis. The energy flows inside the cell. Thus, the statement is false.
What is modern cell theory?Cell theory gave the organizational and fundamental basis of the cell that is the same for both the eukaryotic and the prokaryotic cell including the multicellular and single-celled organisms.
The cells of the organisms all come from a pre-existing cell through reproduction and cell division. The cells are important and crucial for cellular and metabolic fiction.
The energy flows inside the cell in the mitochondria of the cell that power and act as fuel involved in the working of the cell by breaking the bonds stored in the sugar molecule.

Wind power is an excellent option for North Carolina homes, farms, businesses, schools, and utilities interested in producing clean, independent electricity.
List four functions of the muscular system.
The main functions of the muscular system are as follows:
1. Mobility
The muscular system’s main function is to allow movement. When muscles contract, they contribute to the gross and fine movement.
Gross movement refers to large, coordinated motions and includes:
•walking
•running
•swimming
Fine movement involves smaller movements, such as:
•writing
•speaking
•facial expressions
The smaller skeletal muscles are usually responsible for this type of action.
Most muscle movement of the body is under conscious control. However, some movements are reflexive, such as withdrawing a hand from a source of heat.
2. Stability
Muscle tendons stretch over joints and contribute to joint stability. Muscle tendons in the knee joint and the shoulder joint are crucial in stabilization.
The core muscles are those in the abdomen, back, and pelvis, and they also stabilize the body and assist in tasks, such as lifting weights.
3. Posture
Skeletal muscles help keep the body in the correct position when someone is sitting or standing. This is known as posture.
Good posture relies on strong, flexible muscles. Stiff, weak, or tight muscles contribute to poor posture and misalignment of the body.
Long-term, bad posture leads to joint and muscle pain in the shoulders, back, neck, and elsewhere.
4. Circulation
The heart is a muscle that pumps blood throughout the body. The movement of the heart is outside of conscious control, and it contracts automatically when stimulated by electrical signals.
Smooth muscle in the arteries and veins plays a further role in the circulation of blood around the body. These muscles maintain blood pressure and circulation in the event of blood loss or dehydration.
They expand to increase blood flow during times of intense exercise when the body requires more oxygen.

what happens if plant protoplasts are placed in distilled water
Answer:
Protoplasts are plant cells that have had their cell walls removed. What happens if plant protoplasts are placed in distilled water? A They get larger and become turgid.When the plant protoplast is placed in distilled water ; It becomes Turgid
When protoplast is placed in a distilled water, the distilled water flows into the protoplast and this makes the protoplast to become turgid and this is due to absence of the plants cell wall and also the difference in the concentration of the contents of the protoplast and the distilled water. Protoplast represents the plant cell without the presence of the cell wall.
Hence we can conclude that when the plant protoplast is placed in distilled water it becomes Turgid.

3. From the fossil evidence shown, how did the skills change over time?
4. How might the environment in which each of these species lived have affected the evolution of horses?
Answer:
1: 50 million years
2: The forefeet changed over time by the bones merging into one to create the hoofed feet that we are used to today.
3: Their teeth and skull changed over time to better fit the environment and food they fed on. Their feet and hight changed based on the physical requirements of the environment like walking across dense forests vs open prairies and how they had to move to access food.
4: The environment affected the way the horses evolved because they had to evolve to better fit and survive/thrive the new environments they lived in.
What is one role of ATP in the light independent reaction of photosynthesis
i) Explain how the biochemical reaction can still occur if the blood sugar level is lower
than the normal range.
Answer:
To produce energy from available sugar.
Explanation:
The biochemical reaction can still occur if the blood sugar level is lower than the normal range because energy is needed by the body for its activities. The biochemical reactions helps in producing energy in the form of ATP that is needed by the body for its different activities. The lower level of sugar in the blood does not fulfil the needs of body but provides some energy for it so that's why the body produces energy from available sugar present in the body.

Answer:
during cell division daughter cells are genetically identical to the mother cell
Explanation:
DNA replication refers to the biological process by which two identical DNA molecules are produced from one original DNA molecule. DNA replication generates two identical DNA molecules known as sister chromatids which separate during mitosis. After this process, both daughter cells contain identical genetic information as the parent cell. Moreover, DNA replication is semiconservative because the two daughter DNA molecules that are synthesized have one parent (original) DNA strand and one newly synthesized complementary strand.

Which of the following is a feature of all cells?
O A. All cells have a nucleus.
O B. All cells have a rigid cell wall.
O C. All cells are spheres.
O D. All cells have a cell membrane.
All cells have a rigid cell wall is a feature of all cells. Therefore, option (B) is correct.
What are the characteristics of cell wall?A plant cell's cell wall is its outermost covering. It is a tough, pliable, and occasionally rigid layer that provides the cell with structural support and protection. There is no cell wall in animal cells.
Plant cells' tensile strength and resistance to mechanical and osmotic stress are provided by the cell wall, which encloses the plasma membrane. Additionally, it permits the development of turgor pressure, or the pressure of the contents of the cell against the cell wall.
The cell's interior contents are kept separate from the outside environment by the cell wall. It also gives the cell and its organelles shape, support, and protection. However, only a few prokaryotic organisms, eukaryotic plants, and fungi contain this cellular component.
