semi-permeable membrane which encloses the cytoplasm and all of the cellular organelles
Cell membranes act as boundaries and checkpoints. Because of their semi-permeability, some molecules can diffuse across the lipid bilayer but not others. A membrane that is selectively permeable encloses every cell. This membrane serves as a partition between the internal and external environments in addition to enclosing the cellular organelles.
Is a phospholipid bilayer semi-permeable?
As a result, the phospholipid bilayer serves as a semipermeable membrane that enables cells to maintain their internal monolayers in isolation from the outside world and other cells. The tonicity of the fluid bound by a semipermeable membrane can be used to determine the concentration in relation to the surroundings or other cells.

Free radicals produced during biochemical reactions can serve as carcinogens if they are not neutralized by? a. mutator genes b. growth factors c.antioxidants d.repair enzymes e. proto-oncogenes
Answer: C. Antioxidants neutralises free radicals produced during biochemical reaction serve as carcinogens
Antioxidants displace some of their own electrons to counteract free radicals. They serve as a natural "off" switch for the free radicals by making this sacrifice. This aids in stopping a chain reaction that may have an impact on other cellular molecules and other cells across the body.
Explanation:
What are the free radicals in biochemical reactions.
Free radicals are chemical entities that can be thought of as fragments of molecules because they have an unpaired electron and are frequently very reactive. They are continuously created in cells, either unintentionally as waste products of metabolism or on purpose, for example, during phagocytosis.
The oxygen atom and its radical derivatives (superoxide and hydroxyl radical), hydrogen peroxide, and transition metals are the most significant reactants in free radical biochemistry in aerobic cells.
To stop the generation of free radicals or to reduce their destructive effects, cells have evolved a wide range of antioxidant defences. These include proteins that bind transition metals, enzymes that break down peroxides, and a variety of substances that "scavenge" free radicals. Biomolecules can be oxidised by reactive free radicals produced inside of cells, which can cause cell death and tissue damage. Due to these species' short lifespans, it is very challenging to prove that they are involved in the pathogenesis of a disease.

which body system(s) is (are) dedicated to maintaining stable internal conditions by detecting and responding to stimuli?
The body system dedicated to the maintenance of stable internal conditions by detecting and responding to stimuli is the nervous system.
Nervous system and homeostasisHomeostasis refers to the maintenance of relatively constant internal processes such as temperature, pressure, etc. The normal range of operation of processes is referred to as the set point. When these setpoints are breached, it may result in irreversible damage to the body or even death.
Thus, when setpoints are breached, the breach is quickly reported to the control center (the brain) and the brain sets mechanisms in motion to counter whatever is causing a breach to the setpoints.
All these feedbacks happen between the sense organs and the nervous system. The sense organs are able to sense a breach by picking up stimuli, this is conveyed by the nervous system to the brain. The brain then sends messages to muscles, cells, or tissues to counter the breach and return to normalcy.

during cell injury caused by hypoxia, why is there an increase in the osmotic pressure within the cell?
Due to entry of sodium inside the cell, during cell injury caused by hypoxia, there an increase in the osmotic pressure within the cell.
Moving fluid and ions into the cell causes immediate failure of metabolism and a reduction in ATP synthesis in hypoxic damage. Normally, the active-transport enzyme ATPase and the presence of ATP maintain the pump that removes sodium ions from the cell. Reduced ATP and ATPase levels enable sodium to accumulate in the cell while potassium diffuses outward in metabolic failure brought on by hypoxia. More water is drawn into the cell when osmotic pressure rises as intracellular sodium levels rise. The other choices fall short of adequately describing the cell damage brought on by hypoxia, which leads to an increase in osmotic pressure.

why is there a limit to the amount of shortening that can occur in a sarcomere during muscle contraction?
Moreover, a maximal shortening of the muscle only reduces sarcomere length by around 10% (to just under 2 mm). A sarcomere will create less force if it is stretched too far since there won't be enough myofilament overlap. Over-contracted muscles have a reduced capacity for subsequent contractions, which lowers the force generated. Contraction is impaired if the resting length is either too short or too long. The length-tension connection describes how the length of a muscle fiber at rest affects its ability to contract. The amounts of tension and sarcomere length measured during the plateau were used to establish a sarcomere length-tension relation. Between 1.9 and 2.6 micrograms, tension was independent of sarcomere length, and it decreased to 50% of its maximum at 3.4 micrograms.

To focus the eyes on a visual cue, the paramedian pontine reticular formation (PPRF) will cause a fast eye movement or saccade. To swiftly focus the eyes on a visual signal, the paramedian pontine reticular formation (PPRF) will start a rapid eye movement or saccade. The medial longitudinal fasciculus (MLF), which spans the majority of the brain stem, links these regions to the oculomotor, trochlear, and abducens nuclei.
