if there was no S phase during cell division, half of the chromosome will get decreased for each generation.

S phase, also referred to as the "conflation phase," of the cell cycle, which follows after G1 and G2, is when DNA replication takes place. Since adequate genome duplication is required for normal cell division, the conditioning processes that occur during S-phase are tightly controlled and largely conserved. Entering S-phase is controlled by the G1 restriction point (R), which commits cells to the rest of the cell cycle in the presence of adequate nourishment and growth signals. Because this transition is essentially irreversible, even if the terrain is unfavourable after the cell has passed the restrictionpoint, it will still enter the S- phase. In order to control the entry into the S-phase, molecular processes that allow a fast, unidirectional change in cell state are involved.

Oceanic crust is generally composed of dark-colored rocks called basalt and gabbro.

Mid-ocean ridges constantly produce new oceanic crust. Magma rises into the upper mantle and crust at these ridges where continental plates separate. The freshly created rocks cool and begin to disintegrate as the continental plates move away from the ridge, and silt slowly begins to accumulate on top of them. The oceanic ridges are home to the youngest oceanic rocks, and as you move away from the ridges, the rocks grow older and older.

The mantle cools and melts as it rises, and as the pressure drops, it passes the solidus. The temperature of the mantle as it increases is the single factor affecting how much melt is created.

In humans with a typical constitution of chromosomes, X-chromosome inactivation induces dosage compensation by randomly inactivating one of the X chromosomes in the somatic cells of females.

X-chromosome inactivation, also known as Lyonization, is a process that occurs during early development in female embryos to equalize the gene dosage between males and females. Since females have two X chromosomes and males have one X and one Y chromosome, X-chromosome inactivation ensures that both sexes have an equal amount of X chromosome gene products.

During X-chromosome inactivation, one of the X chromosomes in each somatic cell of a female is randomly chosen and inactivated. This inactivated X chromosome undergoes structural and epigenetic changes, forming a condensed structure called a Barr body. The genes on the inactivated X chromosome are effectively silenced and are not actively transcribed.

The random nature of X-chromosome inactivation results in a mosaic pattern in which some cells express genes from the maternal X chromosome, while others express genes from the paternal X chromosome. This ensures that each cell maintains a balanced gene expression level despite having two X chromosomes.

In summary, X-chromosome inactivation induces dosage compensation by randomly inactivating one of the X chromosomes in the somatic cells of females, allowing for equal gene expression between males and females.

The scientist who discovered that all plants are made of cells was Matthias Schleiden. Here option A is the correct answer.

Schleiden was a German botanist who, along with Theodor Schwann, is credited with developing the cell theory. In 1838, Schleiden observed plant tissues under a microscope and noted that they were composed of discrete units that he called "cells."

He also observed that the cell was the basic unit of structure and function in plants and that all plant tissues, including stems, leaves, and roots, were composed of cells. Schleiden's discovery that all plants were composed of cells was a major breakthrough in the field of biology and laid the foundation for cell theory.

The cell theory states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. This theory was later expanded upon by Theodor Schwann, who observed that animal tissues were also composed of cells. Together, Schleiden and Schwann's work helped to establish the fundamental principles of modern biology.

The statement that best explains why there is usually not more than five trophic levels in a food chain is that Energy is lost from each trophic level.

A food chain shows the transfer of energy and nutrients from organisms to organisms in a feeding pathway.

Each step along a feeding pathway is known as a trophic or feeding level.

This feeding pathway in nature follows a certain pattern:

At every trophic level, some of useful energy is lost as heat energy. Thus as we move along the food chain, the amount of useful energy decreases progressively.

Cellulose-rich food substances are a good source of roughage in human beings because a) human beings do not have cellulose-digesting enzymes.

Cellulose is a complex carbohydrate found in the cell walls of plants. While humans lack the enzymes necessary to break down cellulose, it still plays an important role in the digestive system. When we consume cellulose-rich foods, it passes through the digestive tract without being fully digested. Instead, it acts as dietary fiber or roughage.

The presence of cellulose in the diet aids in maintaining healthy digestion and bowel movements. It adds bulk to the stool, promoting regularity and preventing constipation. Additionally, cellulose stimulates the muscles of the digestive tract, aiding in the movement of food through the system.

Although cellulose itself is not digested by humans, it serves as a substrate for cellulose-digesting bacteria present in the large intestine. These bacteria ferment cellulose, breaking it down into smaller components such as short-chain fatty acids. These byproducts of cellulose fermentation provide additional energy and nutrients for the body.

Therefore, while cellulose is not directly digested by humans, it contributes to overall digestive health and acts as an important source of dietary fiber or roughage. Therefore, Option a is correct.

Explanation:

Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Due to Base Substitutions Mutations.

A nonsense mutation refers to a base substitution in which the changed nucleotide transforms the codon into a stop codon.

Such a modification leads to a premature termination of translation, which can badly affect the formation of proteins.

Thus, Base Substitutions Mutations take place.

The false statement about vesicle budding from the Golgi is: Clathrin molecules act at the cytosolic surface of the Golgi membrane. The correct option is d.

Clathrin molecules do not act directly at the cytosolic surface of the Golgi membrane during vesicle budding. Clathrin proteins are involved in the formation of coated pits and vesicles on the cytoplasmic side of the Golgi membrane. These coated pits are lined with clathrin molecules and adaptins, which interact with each other.

The adaptins help to select specific cargo molecules for transport within the vesicles. Once the vesicle has budded off, clathrin molecules remain associated with the vesicle, forming a clathrin coat on the vesicle's outer surface. The clathrin coat is later shed, and the vesicle fuses with its target membrane for cargo delivery.

Therefore, option D is the false statement. Clathrin molecules do not act directly at the cytosolic surface of the Golgi membrane during vesicle budding but instead participate in the formation of coated pits and vesicles on the cytoplasmic side of the Golgi membrane.

In an inducible system, the role of the repressor is to prevent transcription until a specific signal (inducer) is present, and then the repressor will be deactivated, allowing transcription to occur.

In contrast, in a repressible system, the role of the repressor is to continuously prevent transcription until a specific signal (corepressor) is present, which will activate the repressor to bind to the operator and stop transcription.The function of the repressor in an inducible system is to inhibit transcription until a certain signal (inducer) is present, at which point the repressor will be deactivated and transcription will be permitted to proceed. A particular signal (corepressor) must be present in a repressible system for the repressor to be activated, bind to the operator, and stop transcription from occurring.
