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.
Scientists have determined that the codes for amino acids are?
a) different in bacteria and viruses.

d) never the same.
Answer:I
I think its B
Explanation:
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.

If the population of moths is found to have 100% dark colored individuals, would it be possible for them to survive if humans came and cleaned up the pollution on the trunks of the trees; returning them to a light colored bark?
Why or why not?
Explain your reasoning.
Answer:
Decrease occur in the population.
Explanation:
It would be impossible for dark colour moth to survive if humans cleaned up the pollution on the trunks of the trees and returning them to a light colored bark because the dark colored moths can easily be seen by their predators. The dark colour of trunk helps the dark colored moths to hide from their predators so if the black colour of the trunk are turn into light colour so there is decrease occur in the population of black colored moths.

New molecules of DNA are synthesized by copying the genetic sequence of another molecule of DNA, which we call the template, so that __________. View Available Hint(s) New molecules of DNA are synthesized by copying the genetic sequence of another molecule of DNA, which we call the template, so that __________. the helical shape of DNA is conserved during cell division daughter cells are genetically identical to the mother cell there are two copies of each gene on a single DNA molecule DNA can serve as a template for the synthesis of other polymers such as proteins and carbohydrates
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.

2. hypothesis → b. If the amount of daylight increases plant growth, then plants will have higher rates of growth during the summer.
1. law → c. For every action or force in nature, there is an equal and opposite reaction.
Explanation:
THEORY
The scientific theory explains facts or the cause of natural phenomena and makes predictions about them. It is based upon direct observation and scientific methodology.
The theory is fundamental to science because it allows scientists to organize and understand observations.
HYPOTHESIS
A hypothesis is a prediction done by the researcher when trying to answer a problem question. It is a conjecture, which has not been verified yey, nor refused, and that requires corroboration. It is a possibility, but not a fact. The researcher performs the experiment and concludes if the hypothesis is rejected or accepted. The prediction must be objective, expressed in a comprehensive manner, and reflect a logical relation between the variables involved in the experiment.
LAW
Law is a statement that establishes a relationship between variables explaining the cause of natural phenomena. It is based upon empirical information and evidence obtained after many repeated experiments and observations. Many scientists agree with the statement and use it to perform a research project. A law cannot be changed.

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.

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.

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.
