Answer:

New cells are created from a process called cell division. The new cells are produced when a cell, called the mother cell, divides into new cells called daughter cells. When two daughter cells have the same number of chromosomes as the original cell, the process is called mitosis

Explanation:

The release of the protein insulin from pancreatic cells occurs by exocytosis. When blood glucose levels rise after a meal, the beta cells of the pancreas release insulin into the bloodstream. The insulin then binds to receptors on target cells throughout the body, signaling them to uptake glucose from the blood. This helps to regulate blood glucose levels and provide cells with the energy they need to function properly.

Exocytosis is the process by which cells release molecules, such as hormones, neurotransmitters, or enzymes, into the extracellular space. In the case of insulin, it is stored in vesicles within the beta cells of the pancreas. When blood glucose levels rise, calcium ions enter the beta cells, triggering a series of events that cause these vesicles to fuse with the cell membrane and release insulin into the bloodstream.

Overall, the release of insulin from pancreatic cells by exocytosis plays a crucial role in regulating blood glucose levels and maintaining the body's energy balance.

The main reason a new resistant strain can easily take over a system is the antibiotic has eliminated all other bacteria, giving the resistant bacteria more space and resources to grow

The correct answer is A.

When a new resistant strain develops, it is able to easily take over a system because the antibiotic used to kill off the bacteria ends up eliminating all other non-resistant bacteria, leaving more space and resources for the resistant bacteria to grow and reproduce. This gives the resistant bacteria an advantage over the other bacteria, making it easier for them to take over the system.

It is important to note that this is not the case when the antibiotic is able to eliminate both regular and resistant bacteria immediately, as mentioned in option C. Additionally, the resistant strain does not move to the brain, as mentioned in option B, nor does it move from person to person, as mentioned in option D. It is crucial to take necessary precautions to prevent the development and spread of resistant strains in order to combat the issue of antibiotic resistance.

Therefore, the correct answer to the question is A. The antibiotic has eliminated all other bacteria, giving the resistant bacteria more space and resources to grow.

Though the DNA in humans and chimpanzees is about 99% identical, the banding patterns on chromosome 3 can not be used to determine if a human or chimpanzee committed a crime.

While the DNA sequence between humans and chimpanzees is about 99% identical, there are still significant differences that distinguish the two species, and these differences occur throughout the genome, not just in one specific chromosome or region.

Additionally, the 99.9% identity between different humans means that the DNA sequence is still highly similar, and not enough to differentiate between individuals with any reliability for forensic purposes. Forensic DNA analysis typically relies on more variable regions of the genome, such as short tandem repeats (STRs) or single nucleotide polymorphisms (SNPs), which can be used to distinguish between individuals.

1) It may have been underestimated sue to visibility bias

2)  The method of direct microscopic count or direct cell count can be employed.

On the particular agar medium employed, not all bacteria contained in the sediments may be viable or able to grow. Some bacteria might no longer be culturable or in a dormant state, which limits their capacity to grow into colonies on the agar plate. This viability bias may lead to the underestimate of the bacterial population by excluding a sizable fraction of it.

The Theory of Constraints addresses bottlenecks in mask production. The US government expedited vaccine development and production, increased funding, and secured essential supplies to remove constraints.

The Theory of Constraints (TOC) can be applied to the production of breathing masks in the United States by identifying and addressing the bottlenecks or constraints that hinder the production process. For example, during the early stages of the COVID-19 pandemic, there was a shortage of raw materials, manufacturing capacity, and distribution channels for masks. TOC would suggest focusing efforts on alleviating these constraints to increase mask production. This could involve sourcing additional raw materials, expanding manufacturing capabilities, optimizing production lines, and streamlining distribution logistics.

Regarding vaccine production, the U.S. government implemented several measures to remove constraints. They worked to expedite the regulatory approval process for vaccines, facilitating faster development and production. The government provided funding to vaccine manufacturers to expand their manufacturing capacity and ramp up production. They also invoked the Defense Production Act to secure essential supplies and equipment needed for vaccine production. These actions aimed to eliminate constraints such as limited production capacity, logistical challenges, and supply chain disruptions, allowing for a more efficient and accelerated vaccine production process.

The simulation of a chemical reaction does support the scientific law of conversation of mass that states that matter can neither be created nor destroyed but it can change from one form to another.

The scientific law of conservation of mass states that matter can neither be created nor destroyed but it can change from one form to another. This means that the mass of the reactants and the products must be the same, i.e., mass cannot be lost or gained.

For example, when the wood is burned, the products formed are ash, water vapour, and carbon dioxide. The mass of the ash, water vapour, and carbon dioxide formed during the combustion of wood is the same as the mass of the wood that was burned.

The simulation of a chemical reaction supports this scientific law as it has been observed that the mass of the reactants in a chemical reaction is equal to the mass of the products formed during the chemical reaction. Even if the products appear to have a different mass than the reactants, it is only because the mass has changed from one form to another, and not because the mass has been destroyed or created.

For instance, in the process of rusting, iron and oxygen react to form rust, which is hydrated iron(III) oxide. The mass of the iron and oxygen involved in the chemical reaction is equal to the mass of the rust formed. In conclusion, the scientific law of the conversation of mass states that matter can neither be created nor destroyed but it can change from one form to another, which is supported by the simulation of a chemical reaction.

Blood in the fetus is oxygenated in the placenta rather than in the lungs. The umbilical arteries connect the fetus to the placenta.

Fetal breathing occurs 10%-20% of the time during 24-28 weeks of gestation, rising to 30%-40% after 30 weeks. Fetal respiration, which originates in the diaphragm, is irregular in frequency and amplitude and fluctuates during pregnancy. The volume of fluid transported is minimal, and it is inadequate to empty the trachea.

Foetal breathing motions are apparent in humans beginning in the fifteenth week of pregnancy and increasing until the beginning of the third trimester. Breathing motions have been present 30% of the time throughout the previous 10 weeks. Fetal breathing movements (FBM) are critical in lung development because they delay the drainage of fluids from the future airspaces of the lungs, allowing for proper lung expansion.

Meiosis does not cause an organism to grow. While meiosis has important roles in producing gametes, maintaining chromosome number, and generating genetic diversity, it is not responsible for causing an organism to grow.

Meiosis is a specialized form of cell division that occurs in sexually reproducing organisms. Its primary functions include producing gametes (sex cells), reducing the chromosome number in gametes, and creating genetic variability. However, meiosis is not responsible for causing an organism to grow. The growth of an organism occurs through the process of mitosis, which is a type of cell division that leads to the production of somatic cells. Mitosis allows for the increase in cell number, tissue growth, and overall development of an organism. In contrast, meiosis is specifically involved in the formation of gametes, such as sperm and eggs, which are used for sexual reproduction. During meiosis, the chromosome number is reduced by half, ensuring that the offspring receive the correct number of chromosomes from each parent. Additionally, meiosis promotes genetic variability through processes like crossing over and independent assortment, which result in the shuffling and recombination of genetic material.
