Answer:

The respiratory system has cells that produce MOCO OR MUCUS, which trap germs and dust. On their surface they have a large number of cellular structures called CILIAS, whose function is to spread mucus and direct it outwards. In the stomach, the digestive glands produce the STOMACH ACID, which, due to its extreme ACIDITY, attacks and destroys the PATHOGEN MICROORGANISMS that are introduced with food and drink.

Explanation:

In the respiratory and digestive apparatus there are two types of super specialized mucous upholstery, where the cellular world is challenged.

In the respiratory mucosa the production of mucus and the mobilization of the cilia are part of the innate response of the organism as well as the acidity that is generated in the upholstery and in the gastric tract.

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]

Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

Primary succession on Rangitoto Island

In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]

Cloud Subscriptions can be thought of as "renting" a software license month-to-month or year-to-year. This type of license is also referred to as SaaS (software-as-a-service) model.

Software-as-a-Service (SaaS) is a software licensing model, which allows access to software on a subscription basis using external servers. SaaS allows each user to access programs via the Internet, instead of having to install the software on the user's computer.

Cloud-based licensing allows software vendors to give customers access to real-time data to increase profits and lower costs. The cloud allows access to migration data, information on licence use (including those that aren't being used and therefore being wasted), centralised records, etc.

The net energetic cost of converting two pyruvate to one glucose by gluconeogenesis in ATP equivalents is 6 ATP molecules.

During gluconeogenesis, two molecules of pyruvate are converted into one molecule of glucose. This process requires energy in the form of ATP. Let's break down the steps and calculate the ATP equivalents:

1. Conversion of pyruvate to oxaloacetate: This step requires the hydrolysis of one ATP molecule to ADP and Pi (inorganic phosphate). So, for two pyruvate molecules, two ATP molecules are used.

2. Conversion of oxaloacetate to phosphoenolpyruvate (PEP): This step involves the decarboxylation of oxaloacetate and the hydrolysis of one ATP molecule to ADP and Pi. Therefore, two ATP molecules are used.

3. Conversion of PEP to fructose-1,6-bisphosphate: In this step, the hydrolysis of one ATP molecule to ADP and Pi is required. Hence, one ATP molecule is used.

4. Conversion of fructose-1,6-bisphosphate to glucose: The hydrolysis of one ATP molecule to ADP and Pi is needed. So, one ATP molecule is used.

Therefore, the total ATP equivalents required to convert two pyruvate to one glucose by gluconeogenesis is 2 + 2 + 1 + 1 = 6 ATP molecules.

Explanation:

Answer: They breathe air through their lungs.

Explanation:

Respiratory acidosis occurs when partial pressure of carbon dioxide is increased. Respiratory acidosis is a state where the level of carbon dioxide (CO2) in the blood increases, resulting in a decrease in blood pH.

Acute and chronic respiratory acidosis are the two types of respiratory acidosis. The partial pressure of carbon dioxide in arterial blood (PaCO2) determines the severity of respiratory acidosis. It is the pressure exerted by carbon dioxide in the blood.

The normal range of PaCO2 is between 35 and 45 millimeters of mercury (mm Hg). When it goes beyond this range, respiratory acidosis occurs. Typically, respiratory acidosis occurs when PaCO2 is greater than 45 mm Hg.

Protein B, which is 50kD in size and rod-shaped, will elute last out of the gel filtration column.

Supporting answer: Gel filtration chromatography, also known as size exclusion chromatography, separates proteins based on their size. The principle behind this technique is that smaller molecules can enter the pores of the gel matrix more easily, resulting in slower elution, while larger molecules pass through the column more quickly.

In this case, Protein B is both 50kD in size and rod-shaped. The rod-shaped structure implies that it has a more elongated shape compared to the spherical proteins. Due to its elongated structure, Protein B is likely to have a larger hydrodynamic radius (size as perceived by the gel matrix) compared to Protein A, even though they are both 50kD in size.

Answer:Gene and DNA are the two genetic terminologies mainly used to determine the characteristics of a living thing. In general, a gene is a short section of DNA and DNA- Deoxyribonucleic acid is a molecule which carries the genetic instructions or the hereditary materials

Explanation:The difference between DNA and gene are summarized below

Difference between Gene and DNA

Gene DNA- Deoxyribonucleic acid

Genes are the DNA stretches which encode for specific proteins. DNA is a biomolecule, which contains genetic information

Regulates the traits of an organism. Regulates gene regulation.

Gene is a specific sequence present on a short stretch of DNA. DNA made up of two long chains of polynucleotides wound together

Genes are made up of either DNA or RNA. DNA is a polymer of nucleotides

A gene is located on a chromosome. DNA is located within the nucleus of the cell.

Are coded with heredity information. Encodes the genetic instructions.

The distance between the linked genes is (49*201 - 49 - 201 + 1)/2, which is 5050 m.u.

Linked genes are genes that are located on the same chromosome and tend to be inherited together. This is due to the fact that when the chromosome is duplicated and passed on to the offspring, the linked genes are passed on together. Linked genes can also be referred to as close proximity genes or linked loci. Linked genes can be used to study a variety of genetic phenomena, including genetic disorders, genetic polymorphism, and evolutionary divergence. By studying linked genes, researchers can gain insight into how genes interact and influence each other and how they contribute to an organism's phenotype.

The distance between the linked genes can be calculated using the formula d = (ab - a - b + 1)/2,
where a is the number of progeny that are black and transparent, and b is the number of progeny that are pink and black.
In this case, a = 49 and b = 201, so the distance between the linked genes is (49*201 - 49 - 201 + 1)/2, which is 5050 m.u.

that ABO blood type demonstrates multiple allele inheritance of what multiple allele inheritance means. In humans, the ABO blood type is determined by three alleles - A, B, and O. Each person one from each parent, and the are combination  these two alleles determines their blood type.

The A and B alleles are co-dominant, meaning they both express their phenotype when present together. The O allele is recessive and only expresses its phenotype when paired with another O allele. This results in four possible blood types - A, B, AB, and O. So, the inheritance of ABO blood type involves multiple alleles interacting in a complex way to determine a person's phenotype.

The ABO blood type is a trait that demonstrates the type of inheritance known as "codominance." the term are we the "codominance" refers to the type of inheritance exhibited by the ABO blood type  codominance, both alleles for are specific trait are expressed equally in an individual's phenotype, and neither allele is masked or dominates the other. The explanation for this is that ABO blood types have three alleles (A, B, and O), with both the A and B alleles being dominant over the O allele, and the A and B alleles are codominant with each other, leading to four possible blood types: A, B, AB, and O.

C. Cells are the basic building blocks of all living organisms.

a) At pH = pK, the generic amino acid exists in both protonated (NH3+) and deprotonated (NH2) forms.

b) At pH = pK2, the generic amino acid exists in both fully protonated \((NH3+)\) and partially deprotonated (NH3) forms.

c) On the upper, flat portion of the green curve (pH above pK2), the generic amino acid primarily exists in the deprotonated form (NH3).

d) The proportion of the "red" form of the amino acid at pK2 can be estimated by observing the position of the dot on the graph.

a) At pH = pK, the generic amino acid exists in two forms: the protonated form (NH3+) and the deprotonated form (NH2). On the graph, the protonated form is represented by a dot below the green curve, while the deprotonated form is represented by a dot above the green curve.

b) At pH = pK2, the generic amino acid also exists in two forms: the fully protonated form (NH3+) and the partially deprotonated form (NH3). On the graph, the fully protonated form is represented by a dot below the green curve, while the partially deprotonated form is represented by a dot on the flat portion of the green curve.

c) On the upper, flat portion of the green curve (pH above pK2), the generic amino acid exists mainly in the deprotonated form (NH3). This form predominates at high pH levels.

d) At pK2, the amount of the "red" form of the amino acid (partially deprotonated form, NH3) can be determined by observing the position of the dot on the graph corresponding to that pH. The proportion of the red form can be estimated by the distance between the dot and the green curve, with a shorter distance indicating a higher proportion of the red form.

In summary, the graph illustrates the ionization state of the generic amino acid as a function of pH. At specific pH values (pK and pK2), different forms of the amino acid exist, ranging from fully protonated to partially deprotonated. By interpreting the position of the dots on the graph, we can understand the distribution of the amino acid forms at different pH levels.
