Answer:

nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

Explanation:

the air is passed out from alveoli to Bronchioles to bronchi to trachea to larynx to pharynx to nasal cavity to nostrils and the breathed out

Here are the parts of the respiratory system that air passes through as it is breathed out:

The respiratory system is a complex network of organs, tissues, and structures that work together to facilitate the exchange of gases (oxygen and carbon dioxide) between the body and the environment. Its main function is to provide oxygen to the body's cells while removing carbon dioxide, a waste product of metabolism, from the body.

The respiratory system includes the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, and lungs. When we inhale, air enters through the nose or mouth and passes through the respiratory tract, where it is filtered, warmed, and humidified.

Mutation and Genetic Variation

The Galapagos finches evolved from a common ancestor millions of years ago. The evolution into many different species with varying beak sizes, body sizes, songs, and feeding behaviors occurred due to genetic variation introduced through mutations. The shape and size of the finches' beaks are continuously evolving, helping the birds to adapt to their environments. The diagram shows the different species of Galapagos finches.

Peter and Rosemary Grant studied medium ground finches (Geospiza fortis) on the Galapagos island of Daphne Major for over 40 years. Daphne Major was chosen to study the medium ground finches because it had not been inhabited by humans, and contained few predators and little competition with other species of finch. Medium ground finches eat mainly small seeds, insects, and fruits. Each year, the Grants returned to the island and made observations of the finches' beak size, weather, and food supply. In 1977, a drought killed many plants, causing a shortage of small, tender seeds. After all of the tender seeds were gone, large, tough seeds were the only available food source. In 1982, a population of a large ground finch species came to the island and began to colonize. Large ground finches eat mainly large seeds, fruits, caterpillars, and large insects. In 1984, heavy rains on the island resulted in an abundance of small, soft seeds and a shortage of large, tough seeds. A drought in 2003 created another shortage of large seeds. The diagram shows the average beak size of the medium ground finch from 1973 to 2012.

The line-graph shows beak depth in millimeters along the vertical axis from 8 to 10.5, in increments of 0.5. The horizontal axis shows years from 1970 to 2010, in increments of 5. The line starts at 9.5 millimeters around 1973 and drops to slightly more than 9 millimeters in 1975. The line then rises sharply to more than 9.5 millimeters around 1978 and continues until just after 1985 when it drops to 9.5 millimeters. The line continues to drop to a little less than 9.5 millimeters around 1988 and drops again to around 9 millimeters in 1995. The line then remains level until around 2003 when it rises to about 9.25 millimeters. Just before 2005, the line sharply declines to just above 8.5 millimeters and remains level from then on. Significant periods are shown on the graph at 1977 to show a drought, at 1984 to show heavy rainfall, and at 2003 to show a drought.

The nervous system is composed predominantly of neural tissue.

Explanation: Anatomist study anatomy, the study of the structure of organisms or their parts. By observing the structure of the nervous system, anatomist will tell that it is composed predominantly of neural tissue. So, he observed the structure of one part of an organism.

The common structural features of cellulose and chitin are both made up of long unbranched chains of β-glucose and N-acetylglucosamine respectively. These polysaccharides have features such as rigidity, insolubility, and high tensile strength, which are necessary for structural support in plants and fungi.

Cellulose is an organic compound with the formula ₙ, a polysaccharide consisting of linear chains of several hundred to more than ten thousand β bonds of D-glucose units. Cellulose is the main structural component of the cell walls of green plants, many forms of algae and oomycetes. Cellulose is present mostly in the cell walls and woody parts of plants. Cellulose has a role that determines the character of the fiber and allows its use in paper making. For pulping, it is hoped that the fibers will have a high cellulose content. Textile materials from cellulose (cotton) have several characteristics, such as a cold and slightly stiff material, wrinkled easily, absorbs sweat easily, is susceptible to mold, and is flammable.

Most bodily enzymes, including lactase, function best at a temperature of about 37 degrees Celsius.

At temperatures below this, the low kinetic energy of the atoms results in fewer collisions between the enzyme and substrate, a smaller proportion of which have enough activation energy, causing the reaction to proceed slowly. One substrate molecule and one enzyme molecule join forces. At pH 5.0, E. coli lactase is easily inactivated, and at 36°C, its best activity is found between pH 7.0 and pH 7.5. It was discovered that 46°C is the ideal temperature for its action. The critical thermal increment between 45°C and 53°C was calculated to be 56,400 calories per mol. Its inactivation by heat follows the course of a first order reaction.

A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are large molecules made of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

As it moves along the single strand DNA template, DNA polymerase reads the nucleotide bases as it goes, adding additional complementary nucleotides to the primer to create a sequence that is complementary to the template. 749 nucleotides are thought to be replicated by DNA polymerase every second.

Answer: Archaea

Explanation:

The formation of a simple lipid bilayer membrane would not be sufficient for the origin of the cell because a cell requires more than just a physical barrier to separate itself from the environment. While a lipid bilayer can provide a basic barrier to separate the internal and external environments, it cannot perform essential functions required for cellular life.

For instance, in order for a cell to survive, it needs to have the ability to maintain a stable internal environment, a process known as homeostasis. A lipid bilayer alone cannot regulate the flow of molecules and ions across the membrane to maintain a stable internal environment. Therefore, the membrane would need to have specialized proteins that allow for the selective transport of molecules and ions in and out of the cell.

Additionally, a lipid bilayer alone cannot carry out metabolic reactions required for cellular functions. Enzymes and other proteins are required for cellular metabolism, which would need to be present within or attached to the membrane.

Damaged DNAs have to be repaired before cells can proceed to divide mitotically so as to ensure the integrity of the resulting daughter cells.

During mitosis, the DNA of a dividing cell would have to be shared equally between the two resulting daughter cells.

With damaged DNA, the resulting daughter cells' genomes have already been compromised before they even exist and this might impact their normal existence.

Thus, the integrity of the DNA of a cell that wants to divide must be certified by the cell cycle checkpoints before active division can take place.

Answer:

Sclerenchyma is Greek word where "Sclero-" means hard and "enchyma" means infusion. This tissue consists of thick-walled, dead cells and protoplasm is negligible.

The image in the correct order in which mitosis will occur will be 3, 4, 2, and 1.

It is the division of vegetative cells that results in the formation of 2 daughter cells.

There are 4 stages of mitosis - prophase, metaphase, anaphase, and telophase. Thereafter, the cytoplasm divides in a process known as cytokinesis.

At prophase, the nuclear membrane dissolves and the chromatin material condenses.

At metaphase, the chromosomes align at the center of the cell while the spindle fiber engages each of them from the opposite ends of the cell.

At anaphase, chromosomes are pulled apart and sister chromatids of the same chromosome begin migrating towards opposite ends of the cell.

At telophase, migration of chomatids complete.

Thereafter, the nuclear membrane reappears around each chromosome, the chromosomes decondense, and the cytoplasm divides to give two independent cells.
