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

Zymogen cells, also known as chief cells, are found in the stomach and are responsible for producing and secreting pepsinogen, a precursor enzyme that is converted to pepsin, a digestive enzyme that breaks down proteins.

Explanation

• Ticks and mites are members of the subclass Acari, which is a group of tiny arachnids that includes many parasitic species.
• Ticks are ectoparasites that feed on the blood of animals and humans, while mites include both free-living and parasitic species, with some feeding on skin, blood, or other bodily secretions.

Explanation

• IgE antibodies are responsible for triggering an allergic response when they combine with an allergen.
• This binding causes mast cells to release histamine and other chemical mediators, leading to allergic symptoms such as itching, swelling, and increased mucus production.

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

• Jellyfish are bioluminescent.
• They are capable of producing and emitting light, often for purposes such as attracting prey or mates, camouflage, or self-defense.

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

• The syncytial theory, also known as the "syncytial hypothesis," proposes that metazoa (multicellular animals) evolved from a single, giant cell or syncytium.
• According to this theory, the first metazoan was a large, multinucleate cell that eventually gave rise to multiple cells, leading to the development of multicellularity.

Explanation

• In protein synthesis, the initiation of a polypeptide chain is typically started by an amino acid called methionine (Met).
• This is because methionine has a special tRNA (transfer RNA) that recognizes the start codon (AUG) on the mRNA (messenger RNA) and initiates protein synthesis.

Explanation

• Dragonflies, like all insects, have an "open circulatory system", which means that they do not have a closed system of blood vessels like humans or other animals.
• Instead, they have a network of tiny tubes called tracheae that bring oxygen directly to their cells, and they do not need a circulatory system to transport gas.
