Answers

Answer 1

A normal or narrow QRS complex indicates that the impulse was not formed in the ventricles and is termed supraventricular tachycardia.

Narrow (normal) QRS complexes indicate that the ventricles are depolarized normally; this can only be the case if the impulse (which depolarizes the ventricles) passes through the bundle of His, and hence it originates in the atria. In other words, tachycardias with narrow QRS complexes originate in the atria.

A narrow QRS complex (<120 ms) reflects rapid activation of the ventricles via the normal bundle of His-Purkinje system, which in turn suggests that the arrhythmia originates above or within the His bundle so supraventricular tachycardia occurs. Although such type of tachycardia often occurs in patients with a normal heart and rarely represents life threatening conditions.

Meiosis produces our sex cells or gametes. (eggs in females and sperm in males).
O true
O false

Answers

Answer:

True

Explanation:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

True. Meiosis produces our sex cells or gametes.

What is meiosis?

Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce haploid gametes (sperm and eggs) with half the number of chromosomes as the parent cell. It involves two successive cell divisions, known as meiosis I and meiosis II, each of which consists of a series of stages, including prophase, metaphase, anaphase, and telophase.

During meiosis I, homologous chromosomes pair up and exchange genetic information in a process called crossing-over, which increases genetic diversity. The paired homologous chromosomes then separate and move to opposite poles of the cell, resulting in two daughter cells that have half the number of chromosomes as the parent cell.

In meiosis II, the sister chromatids of each chromosome separate, resulting in four haploid daughter cells with unique combinations of genetic information.

If the cell's external environment becomes very WATERY (dilute) then the outside of the cell will have a higher water concentration. We say the cell environment is HYPOTONIC. Water will diffuse in this case.
Which way is the water going to diffuse?

Answers

The cell's exterior cell will contain higher water percentage if the external environment of the cell becomes particularly watery (dilute). The cell milieu is referred to as hypotonic. In this situation, water will diffuse.

A hypotonic solution is what is it?

Any external solution with a low solute content and a high water concentration in comparison to body fluids is referred to as a hypotonic therapeutic solution. There is a net transfer of water first from solution through into body in hypotonic solutions.

Has hypotonic water gained?

When a cell is in a concentrated solution, water goes out of the cytoplasm when both solutions equal isotonic because the workaround has a greater moisture content than the cell cytosol. When cells are submerged in a hypotonic solution, their surfaces will absorb water.

Answers

Insertion mutation occurs when an extra base pair is added to a sequence of bases.

In general, a Point mutation refers to alteration in a single base pair of DNA by substitution, deletion, or insertion of a single nitrogenous base. Most common example of point mutation is sickle cell anemia. that consists of mutation in a single base pair in the beta-globin chain of hemoglobin pigment in the blood cells. Thus, An insertion can involve the addition of any number of nucleotides, that can be a single nucleotide or an entire piece of a chromosome.

An insertion is a point mutation in which one or more base pairs is added to a DNA sequence. Point mutations is further divided into silent mutations, missense mutations, and nonsense mutations.

Humans, social and economic organisations, and living things are all competing entities. It provides people a variety of employers and working settings while also creating jobs.

Additionally, competition lessens the need for government intervention through business regulation. Consumers, society, and individual liberty all benefit from a healthy, competitive free market.

What would happen if a mistake were not caught by the proofreading mechanism and became permanent in the DNA

Answers

If a mistake were not caught by the proofreading mechanism and became permanently incorporated into the DNA, the consequences could be catastrophic.

The DNA is the blueprint for all life, and any mutation or alteration can cause a range of problems, from minor to severe. If the mistake were to alter a gene that is important for cell survival, it could lead to a range of health problems, from mild to life-threatening.

For example, if a gene that is responsible for the production of a certain enzyme is altered, it can cause a metabolic disorder, leading to physical and mental disabilities. If the mistake were to alter a gene that is responsible for the functioning of a specific organ, such as the heart or brain, it could lead to serious health problems, such as heart defects or neurological disorders.

If the mistake were to alter a gene responsible for the development of an organism, it could lead to serious developmental defects or even death. For example, if a gene that provides instructions for the development of the body's organs is altered, it could lead to serious malformations or even death.

In addition to the health risks, a mistake in the DNA could also lead to changes in the species. For example, if a mutation alters a gene that is important for the survival of a species, it could lead to the extinction of the species. This could be due to a decrease in fertility, a decrease in the population size, or an inability to adapt to a changing environment.

Explain how the tructure of a cell allow localization of reaction, protection from reactive molecule, and greater efficiency of cellular procee than a bacterial cell

Answers

A eukaryotic cell's structure allows for the localization of reactions because there are areas within the cell where particular enzymes colocalize.

Structural barriers are also used to protect against reactive molecules, and the division of work in this cell allows for greater efficiency of cellular processes than in a bacterial cell. In a eukaryotic cell, the phrase "subdivision of work" refers to the existence of several cell compartments, such as those connected to certain organelles that offer an appropriate medium for carrying out specific reactions, such as the presence of hydrolytic enzymes in lysosomes. As a result, according to the findings, division of labour is essential for eukaryotic cells to carry out various activities, which translates to greater metabolic efficiency when compared to bacteria.
