Answer:

C) Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is lacking completely in cell III.

Explanation:

The  explanation that is most accurate between these two contrasting claims is that Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is completely lacking in cell III, which is in Option C.

The nucleus is present in the eukaryotic cell while it is absent in the prokaryotes, and in the nucleus are the enzymes for DNA replication, transcription, and so on that can make the DNA and the mRNA, as well as the genetic contents. The nuclear membrane acts as a barrier between the genomic contents and the cytoplasm, and transportation takes place through it.

Hence, the explanation that is most accurate between these two contrasting claims is that Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is completely lacking in cell III, which is in Option C.

When breathing in, air enters the larynx through an opening called the glottis.

The larynx, also known as the voice box, is a part of the respiratory system located in the neck. It is responsible for protecting the trachea (windpipe) during swallowing and producing sound. The glottis is a slit-like opening located between the vocal cords in the larynx. As we inhale, the vocal cords move apart, allowing air to pass through the glottis and into the larynx, then further down into the trachea and eventually the lungs.

The glottis is the crucial opening in the larynx through which air passes during inhalation.

Explanation:

Stomach acid breaks down proteins is the process that best describes a physical change that occurs during digestion.

When a protein source attains your stomach, it is divided into smaller chains of Amino acids by hydrochloric acid and proteases. Peptides connect amino acids, which are broken down by proteases. These smaller amino acid chains pass from your stomach into your small intestine.

Lipase is an enzyme that converts fats into fatty acids. Protein is broken down into amino acids by protease.

When you eat something, your body's digestive system breaks it down into individual amino acids, that are consumed and utilized by cells to construct other proteins as well as a few other macromolecules like DNA.

Nine amino acids are needed to travel through the thickness of the membrane.

Alpha-axial helix's distance between amino acids is 1.5. A

The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.

Therefore, the helix's length is (21 X 1.5) = 31.5.

One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A

The thickness of the membrane is determined by the formula above to be 31.5 AA.

In the beta-strand, there is 3.5 AA between each amino acid.

Therefore, (31.5/3.5) = 9 amino acids are needed.

Answer:

ATP is the energy-carrying molecule produced by the mitochondria through a series of chemical reactions.

Explanation:

The correct answer is (d) egg cells. Egg cells, also known as oocytes or ova, possess several features that make them suitable for biochemical studies of the cell-cycle control system.

These features include their large size and arrest in a G2-like phase. Egg cells are typically larger in size compared to other cell types, which makes them easier to handle and manipulate during biochemical experiments. Their large size also allows for the extraction of sufficient amounts of cellular material for analysis. Eggs, or oocytes, possess several advantageous characteristics that make them ideal for studying the cell-cycle control system in biochemical studies. Eggs are considerably larger in size compared to other cell types, providing ample material for experimental analysis. Additionally, eggs naturally undergo arrest in a G2-like phase, allowing researchers to easily synchronize and study specific stages of the cell cycle. This property simplifies the investigation of cell-cycle regulatory mechanisms and facilitates the identification of key molecules involved in controlling the progression of the cell cycle.

The term that means "a benign, fibrous tumor of the uterus" is "uterine fibroid." Uterine fibroids, also known as leiomyomas, are non-cancerous growths that develop in the muscular wall of the uterus, or womb.

They are composed of smooth muscle cells and fibrous connective tissue. Uterine fibroids can vary in size, ranging from small, pea-sized nodules to large masses that can distort the shape and size of the uterus.

The exact cause of uterine fibroids is not fully understood, but hormonal factors, particularly estrogen and progesterone, are thought to play a role in their development.

These hormones stimulate the growth of the uterine lining during the menstrual cycle, and it is believed that fibroids arise from the overgrowth of uterine muscle cells in response to hormonal imbalances.

Uterine fibroids are commonly found in women of reproductive age, and some estimates suggest that up to 80% of women may develop fibroids by the age of 50.

However, not all fibroids cause symptoms, and many women may be unaware of their presence unless they are discovered during routine medical examinations.

Answer:

A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.

Explanation:

During sexual reproduction, meiosis produces the sex cells that combine to make new children.

Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.

Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.

The true statement regarding helminths is that they can all be considered as cellular obligate parasites.

Helminths are a type of parasitic worm that is often found living inside the host's body, feeding on its nutrients and causing various health problems. These organisms typically require a host to complete their life cycle and cause various diseases. They are not protozoans, which are unicellular organisms, and they are not all hermaphroditic, meaning they do not all have both male and female reproductive organs. They are multicellular worms.
As for the left-right halves being biplanar opposites, this is not a characteristic of helminths. The body plan of helminths is often elongated and cylindrical, with a distinct head and tail end. However, their body shape may vary depending on the species. In summary, while helminths are not protozoans and do not have a biplanar body plan or universal hermaphroditism, they are obligate parasites that rely on their host for survival.

Eyelashes are shorter than terminal hairs on the scalp because the growth stage of an eyelash is shorter and eyelashes grow slower than terminal hairs.

The length of hair, including eyelashes and terminal hairs on the scalp, is determined by the growth stage and rate of the hair follicle. In the case of eyelashes being shorter than terminal hairs on the scalp, two main factors contribute to this difference.

Firstly, the growth stage of an eyelash is shorter compared to that of a terminal hair on the scalp. Hair follicles go through growth cycles consisting of active growth (anagen), regression (catagen), and resting (telogen) phases. The anagen phase, during which the hair actively grows, is shorter for eyelashes than for terminal hairs on the scalp. As a result, eyelashes have a limited time to grow and reach their maximum length.

Secondly, eyelashes generally have a slower growth rate compared to terminal hairs on the scalp. The rate of cell division and hair growth in the hair follicle is influenced by various factors, including genetics, hormones, and blood supply. Although not explicitly mentioned in the given options, the slower growth rate of eyelashes may contribute to their relatively shorter length compared to terminal hairs on the scalp.
