Explanation:

The most primitive vertebrates are members of the group of jawless fishes, specifically the Agnatha.

Agnatha is a superclass of vertebrates that includes two extant groups: the lampreys (Petromyzontida) and the hagfishes (Myxini).Jawless fishes are considered primitive because they lack certain characteristics that are present in more advanced vertebrates.

One significant feature they lack is jaws, which are found in more derived vertebrate groups such as cartilaginous fishes (sharks and rays) and bony fishes. Instead of jaws, jawless fishes have a circular mouth lined with rows of teeth.

Another distinguishing feature of jawless fishes is the absence of paired fins. While they do possess unpaired fins, such as a single dorsal fin and a caudal fin, they lack the pectoral and pelvic fins found in more advanced fishes.

Additionally, jawless fishes have simple cartilaginous skeletons rather than bony skeletons, which are characteristic of many other vertebrate groups. They also lack scales and have smooth, slimy skin.

Jawless fishes have a long evolutionary history and are believed to represent an early divergence within the vertebrate lineage. Their primitive characteristics make them valuable for understanding the early evolution of vertebrates and provide insights into the transition from aquatic organisms to more advanced vertebrate groups.

The outer shell membrane in an animal cell represents the cell membrane.

The cell membrane, also called the plasma membrane,

The plasma membrane is a vital component that surrounds the cell, acting as a protective barrier and controlling the movement of substances into and out of the cell. It consists of a phospholipid bilayer embedded with various proteins that serve essential functions.

The phospholipid bilayer provides the foundation of the plasma membrane, with its hydrophilic heads facing the watery extracellular and intracellular environments, and the hydrophobic tails oriented towards the interior of the membrane. This structure creates a selectively permeable barrier that regulates the passage of molecules and ions.

The proteins embedded in the plasma membrane play diverse roles. Some proteins serve as transporters or channels, facilitating the movement of specific substances across the membrane.

Others act as receptors, allowing the cell to receive and respond to external signals. Additionally, there are proteins involved in cell adhesion, cell signaling, and enzymatic activities.

The plasma membrane is essential for maintaining the cell's internal environment and integrity. It regulates the exchange of nutrients, waste products, and signaling molecules, while preventing the loss of vital cellular components.

Moreover, the plasma membrane plays a crucial role in cell recognition and communication, enabling interactions with neighboring cells and the surrounding environment.

Overall, the outer shell membrane, or plasma membrane, is a dynamic structure that is fundamental to the proper functioning and survival of animal cells.

Its selective permeability and various protein components contribute to a range of cellular processes, making it a key player in maintaining cellular homeostasis and facilitating interactions with the external environment.

The frequency of the dominant allele in the population is approximately 0.7241 or 72.41%.

In a population that is in Hardy-Weinberg equilibrium, the frequency of the recessive trait (q²) can be determined as 16%. To find the frequency of the dominant allele (p), we need to take the square root of the complement of the recessive trait frequency.

Let's denote the frequency of dominant allele as p and the frequency of the recessive allele as q. According to the Hardy-Weinberg equilibrium equation;

p² + 2pq + q² = 1

We know that q² (the frequency of the recessive trait) is 0.16. So, we will substitute this value into the equation;

p² + 2pq + 0.16 = 1

Since p² + 2pq represents the frequency of individuals with the dominant trait, and the complement of q² is 2pq, we can rearrange the equation;

2pq = 1 - 0.16

2pq = 0.84

Now we solve for p. To isolate p, we divide both sides of the equation by 2q;

p = (0.84) / (2q)

Since q is the square root of q², which is 0.16, we have:

q = √(0.16) = 0.4

Now we can substitute the value of q into the equation to find p;

p = (0.84) / (2 × 0.4)

p = 0.84 / 0.8

p = 1.05

However, we can't have a frequency greater than 1, so we need to adjust for this by rescaling the frequencies. We can divide both p and q by the sum of their frequencies to obtain the corrected frequencies;

p' = p / (p + q)

q' = q / (p + q)

p' = 1.05 / (1.05 + 0.4)

p' = 1.05 / 1.45

p' = 0.7241

Therefore, the frequency of the dominant allele in the population is approximately 0.7241 or 72.41%.

Lymphatic organs that filter lymph before it enters the blood is Lymph nodes.

The lymphatic framework is an organ structure in vertebrates that is fundamental for the protected system, and reciprocal to the circulatory system. It includes an immense association of lymphatic vessels, lymph centers, lymphatic or lymphoid organs, and lymphoid tissues.

The vessels convey an undeniable fluid called lymph (the Latin word lympha suggests the lord of new water, "Lympha") back towards the heart, for re-dissemination.Not at all like the circulatory system that is a closed structure, the lymphatic system is open. The human circulatory structure processes an ordinary of 20 liters of blood every day through thin filtration, which kills plasma from the blood.

Lymph hubs are explicit tissue masses that are arranged along lymphatic structure pathways. They channel lymph fluid preceding returning it to the dissemination framework. Lymph hubs can be found in each space of the body.

A parasitic bacteria contaminated her food.

Explanation:

A parasitic organism is that which derives nutrients from another, usually called a host, by harming it. In this case of Arainne who fell sick after traveling abroad and eating different countries' food, it indicates that a microbe that is harming her (leading to health complications) has contaminated her food.

Contrary to a parasitic organism, a mutualistic and commensalistic organism will not cause harm to any organism they interact with. Only a parasite will deteriorate the health and physical well being of its host in the process of obtaining nutrients. A predatorial organism kills its pretty, which is not the case here.

Therefore, Arianne's current health condition is as a result of the contamination of the food she ate by a parasitic bacteria.

While both anaerobic and aerobic respiration involves the regeneration of NAD+ and the production of ATP, the specific processes and final electron acceptors differ, leading to variations in ATP yield.

Both anaerobic and aerobic respiration involves the regeneration of NAD+ to produce ATP and NADH. However, there are some differences in how this occurs between the two processes. In anaerobic respiration, since oxygen is not available as the final electron acceptor, an alternative molecule, such as an inorganic compound or an organic molecule, is used.

This molecule accepts the electrons from NADH, resulting in the regeneration of NAD+ and the production of ATP. The specific molecule that accepts the electrons can vary depending on the type of anaerobic respiration occurring. For example, in lactic acid fermentation, pyruvate accepts the electrons from NADH, forming lactate and regenerating NAD+.

Anaerobic respiration produces fewer ATP molecules compared to aerobic respiration because the final electron acceptor in anaerobic respiration has a lower energy yield than oxygen. In aerobic respiration, each molecule of glucose can produce up to 36-38 ATP molecules, while anaerobic respiration typically yields around 2 ATP molecules per molecule of glucose.
