The primary function of the muscular system is movement.
What is muscles?
The muscular system is a group of organs that includes skeletal, smooth, and cardiac muscle. It allows the body to move, maintains posture, and circulates blood throughout the body. Although some muscles (such as the heart muscle) are entirely autonomous, the nervous system controls the muscular systems in vertebrates. It forms the musculoskeletal system in humans, along with the skeletal system, and is responsible for body movement.
Muscles control movement and are linked to bones, internal organs, and blood arteries. Muscle contraction causes nearly all movement in the body.

The cells membrane is permeable to saline but saline concentrations in the cell do not change when diffusion is allowed to take place. Why?
During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will:
a. move across the membrane to the outside of the cell.
b. stop moving across the membrane.
c. continue to move across the membrane in both directions.
d. move across the membrane to inside the cell.
The cell membrane is a organic membrane that separates and protects the indoors of all cells from the outdoor environment.The cellular membrane consists of a lipid bilayer this is semipermeable. The mobile membrane regulates the transport of substances getting into and exiting the cell.
Diffusion is the net movement of anything commonly from a area of higher concentration to a area of lower attention. Diffusion is driven through a gradient in Gibbs loose energy or chemical capacity.
One of the foremost traits of diffusion is the movement of molecules alongside the attention gradient. When this could be facilitated with the aid of other molecules, it does no longer without delay involve high-electricity molecules which includes adenosine triphosphate (ATP) or guanosine triphosphate (GTP).

Law of dominance is the Mendel's law which is demonstrated by the data.
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent.
Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

C4H12+7O2 = 6H2O+4CO2 What is the name for this chemical reaction? I need the acual name for what this is called together.. Thank you.
The given chemical reaction: C4H12+7O2 = 6H2O+4CO2 is a type of Combustion reaction.
A combustion reaction takes place when oxygen (O2) reacts with a chemical substance and energy is released in the form of heat as well as light. Combustion reactions always require oxygen.
The chemical reaction: C4H12+7O2 = 6H2O+4CO2 represents a combustion reaction of a hydrocarbon, which is C4H12 in this case. The combustion of hydrocarbons in the presence of oxygen leads to the formation of carbon dioxide (CO2) and water (H2O) as products.

Explain how Mendel’s data supported his hypothesis. Support your answer by citing textual and evidence from this lesson.
Mendel's hypothesis suggested that every one plant might have received two 'factors' for each trait, one from each parent plant during cross-pollination between purple-flowered and white-flowered plants.
Mendel's data supported this hypothesis as all first-generation (F₁) plants had purple flowers but 1/4th second-generation (F₂) plants possessed white flowers. Mendel termed this characteristic the recessive trait as compared to the rest 3/4th second-generation plants with purple flowers, which contained the dominant trait.
Based on these results, Mendel hypothesized that certain traits like white flower color are expressed only when the plant received both the factors that were responsible for white flower color.

One fertilized egg (ovum), which develops into two children with the same genetic makeup, produces identical or monozygotic twins.
Two eggs (ova) are fertilized by two sperm to create fraternal or dizygotic twins, which are two genetically distinct children. Twin studies make it possible to separate the shared genetic and environmental factors that contribute to the desired trait. Researchers can calculate how much of a trait's variance is due to genetic variation versus how much is due to shared or unshared environments. Identical twins, also known as monozygotic twins, are produced when a single egg is fertilized by a single sperm, resulting in the fertilized egg splitting into two.

Glycolysis occurs in cytoplasm
Explanation:
The enzymes required for the glycolytic pathway are only found in the cytoplasm. A transport protein is required to move glucose across membranes.
if needed, protein can help to maintain a steady blood glucose level
a. True
b. False
The given statement is true as if needed, protein can help to maintain a steady blood glucose level and so meet the glucose needs of the brain.
With enough insulin, protein has no impact on blood glucose levels. However, when there is a lack of insulin, gluconeogenesis progresses quickly and raises blood sugar levels.
Proteins and glucose interact nonenzymatically in physiological settings. In diabetic patients with high blood sugar levels, this glycation is amplified and results in a number of problems. The most prevalent protein in plasma is human albumin serum (HSA), which is glycated by glucose.
Gluconeogenic substrates, such as proteins, can be utilised during fasting or low-carbohydrate diets to create glucose. In general, high-protein (HP) diets contain little carbs and are thought to encourage postprandial gluconeogenesis.

As stimulus strength is increased, the force of a twitch response increases. What does this represent?.
The correct answer is the increased requirement of motor units.
The force of muscle contraction increases with the strength of the stimulus. This is because the contraction of individual muscle fibers increases as the intensity of the stimulus increases. The greater the stimulus, the greater the force the muscle will not contract. Muscles respond to stronger stimuli with the same force. In skeletal muscle, motor neurons can innervate many muscle fibers.
At high stimulation voltages, the muscle response reaches its maximum amplitude. Since the muscle is already working at its best, the muscle response does not continue to increase with increasing stimulation voltage. The stronger the stimulation, the more nerve fibers are stimulated and the more motor neurons are activated. Recruiting additional fibers can increase contractile force.
