Non-disjunction is the process of sister chromatids not separating at the centromere during cell division.
What is cell division?
The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle. Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells. A vital process for life is mitosis.

The several ways how an immune system can defend the body against pathogens are:
1) Mechanical and chemical barriers as the first line of defense
2) The inflammatory response and phagocytosis are the second line of defense.
3) Natural killer cells and specific immunological responses serve as the third line of defense.
There are three layers of defense in immune function, which is the internal environment's defense against invading cells, proteins, and viruses. A series of barriers between the internal and external environments serves as the initial line of defense.
The innate inflammatory response (including phagocytosis) makes up the second line, while the adaptive immune responses and the innate defense provided by natural killer cells make up the third line.
Of course, the first two lines of defense do not apply to tumor cells that develop inside the body, thus the third line of defense must be used to combat them.

In the absence of a dominant allele, a recessive allele is a type of genetic coding that has no impact on phenotype. The more pronounced effects of the dominant allele in a recessive relationship between two alleles obscure the effects of the recessive allele. An allele is a particular variation of a gene or a particular DNA fragment. Different alleles generate a somewhat different set of proteins with various functions.

how many sets of chromosome 21 are present in each cell after 1) mitosis, 2) meiosis, and 3) if a nondisjunction event occurred during anaphase i?
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move on to the third and final phase of meiosis: meiosis II.
At the end of meiosis I there are two haploid cells. Most of complete trisomy 21 is caused by chromosome nondisjunction that occurs during maternal meiotic division (∼90%). Errors occur more frequently in the first maternal meiotic division than in the second. Nondisjunction can occur during meiosis I and meiosis II, resulting in abnormal number of gamete chromosomes. The key difference between nondisjunction in meiosis 1 and 2 is that during meiosis 1, the homologous chromosomes do not separate while in meiosis II the sister chromatids do not separate. Each chromosome contains 1 DNA in anaphase II meiosis. The remaining centromeric cohesin is cleaved in anaphase II, allowing segregation of sister chromatids. The mother cell remains diploid in nature (46 chromosomes in each cell) after meiosis I. After meiosis II, when each mother cell divides into two gametes, each gamete cell contains 23 chromosomes.

The pressure in the lungs increases is not a part of inspiration.
The process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, primarily to flush out carbon dioxide and bring in oxygen, is known as breathing (or ventilation).
The process of taking air into the lungs is known as inspiration (inhalation). Because it is the result of muscle contraction, it is the active phase of ventilation. The diaphragm contracts and the thoracic cavity expands during inspiration. This lowers the intraalveolar pressure, allowing air to enter the lungs.
Expiration (exhalation) is the process by which air is expelled from the lungs during the breathing cycle. The relaxation of the diaphragm and elastic recoil of tissue during expiration reduces thoracic volume while increasing intraalveolar pressure. Expiration forces air from the lungs.

When a neuron is not producing an electrical signal, it is at rest. During this period, the neuron's inside is negatively correlated with its exterior.
Once the sodium channels open, the neuron totally depolarizes to a membrane potential of about +40 mV. Action potentials are referred to as "all-or-nothing" occurrences because, once the threshold potential is reached, the neuron always completely depolarizes. Most animal cells have a negative resting membrane potential because their interiors are more negatively charged than their exteriors. The resting membrane potential can only be accurately described in this way.
Na+ is drawn to the inside of dormant neurons by two different mechanisms. The high concentration of Na+ outside the cell initially pushes Na+ down the gradient of concentration into the cell. Second, the negative charge of the neuron creates an electrical gradient that tends to pull the positively charged ion within the cell.

The term "desiccation tolerance" describes an organism's capacity to withstand or endure conditions of extreme dryness or drought-like conditions. Physiological or behavioural adaptations to endure these periods have been required to ensure the survival of animals and plants that live in arid as well as periodically arid environments, such as transient streams or ponds. In particular, insects use a variety of defence mechanisms to prevent desiccation because they occupy a broad range of ecologically diverse niches. Typically, the change in mass under dry conditions is used to gauge an insect's desiccation resistance. As respiratory water loss is typically regarded as negligible, the overall mass difference among measurements before and following exposure to aridity is credited to body water loss.

why do lipoprotein particles (e.g. vldl) only have a monolayer of phospholipids instead of a typical lipid bilayer?
Lipoprotein particles only have a monolayer of phospholipids because the phosphate of the lipids interacts with the triglycerides and cholesterol esters of the particle. The monolayer protects the particles from bile acids.
What is the role of the phospholipid monolayer at the outer surface of lipoprotein particles?
The lipid monolayer, along with binding proteins, that surround lipid droplets is what helps stabilize the oil drop in the aqueous cell environment due to the amphipathic nature of these molecules.
What are the functions of lipid monolayer?
Lipid monolayers are used as experimental model systems to study the physical-chemical properties of biomembranes. With this purpose, surface pressure/area per molecule isotherms provide a way to obtain information on the packing and compressibility properties of the lipids.
What is the difference between monolayer and bilayer?
The difference is that in bilayers the flux of solution is expressed as a volume change of the vesicles and in monolayers as an area change. By extension, the same approach should apply to the surface pressure area lipid process.
