Explanation

The correct answer is: Set the thief to catch the thief is a idiomatic expression, and the correct changed voice (passive voice) would be: "Let the thief be set to catch the thief".

Explanation

• A J-shaped growth curve is a characteristic of exponential growth, where the population grows rapidly and unchecked, with no limits or restrictions.
• This type of growth occurs when a population has unlimited resources, such as food, water, and space, and is able to grow at its maximum rate, known as its biotic potential.

Explanation

• Blood is slightly alkaline, with a pH range of 7.35 to 7.45.
• This narrow pH range is tightly regulated by the body's acid-base homeostasis mechanisms to ensure proper functioning of various physiological processes.

Explanation

Microtubules are a type of cytoskeletal filament that play a crucial role in moving organelles, vesicles, and chromosomes within cells.

They are involved in various cellular processes, including:

• Intracellular transport (e.g., moving mitochondria, vesicles, and chromosomes)
• Cell division (e.g., separating chromosomes during mitosis)
• Cilia and flagella structure and movement
• Maintaining cell shape and mechanical integrity

Explanation

• The mismatched one is "Glass snake."
• The other three are all types of snakes: Coral snake, Sea snake, and Rattlesnake.
• However, the glass snake is not a snake; it's a legless lizard.

Explanation

The answer is H.J. Muller.

In his experiments, Muller exposed fruit flies (Drosophila) to X-rays, mated the flies, and observed the number of mutations in the offspring.

In 1927, Muller described the results of his experiments in "Artificial Transmutation of the Gene" and "The Problem of Genic Modification".

Explanation

• When cells become specialized, they undergo a process called differentiation, where they develop specific structures and functions to perform specific roles in the body.
• During differentiation, cells transcribe different genes, meaning they express different sets of genes that are specific to their specialized function.
• This leads to the production of different proteins and molecules that enable the cell to perform its unique function.

Explanation

• A Barr body is a densely staining body found in the interphase nuclei of somatic cells of female mammals, including humans.
• It is a condensed, inactivated X chromosome, which is one of the two X chromosomes present in the nuclei of female cells.
• The Barr body is a result of X-chromosome inactivation, a process that occurs in female mammals to avoid a doubling of gene expression.

Explanation

The river flows under the bridge can be used when the flow of the river is normal.

Note: during a flood, when the river has more water beyond its carrying capacity, then at times it starts flowing above the river.
