Answer: Proteins change shape as temperatures change. Because so much of an enzyme's activity is based on its shape, temperature changes can mess up the process and the enzyme won't work. High enough temperatures will cause the enzyme to denature and have its structure start to break up. Enzymes are responsible for many of the chemical processes that take place in animals, plants and microbes. They play a critical role in all life on Earth. Because every enzyme has a specific role and function, a change in its tertiary structure would cause the enzyme to be impaired in its function.
Explanation:
Answer: The nucleolus works to transcribe ribosomal RNA (RNA) and it forms incomplete ribosomes by combining proteins and RNA. Other functions of this structure include transporting molecules, vital substances and ions to ensure efficient cell metabolism.
Explanation:
The nucleolus is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly. Nucleoli also have other important functions like assembly of signal recognition particles and playing a role in the cell's response to stress. Nucleoli are made of proteins and RNA and form around specific chromosomal regions.
Answer:
Explanation:
The fibrous root is one of the small hair-like roots of the fibrous root system. Fibrous roots are derived from the base of the plant. This root system is available mainly in Monocotyledons, Gymnospermae (conifers) and Pteridophyta (ferns). Most of the fibrous roots grow horizontally and very few roots grow vertically to anchor the plant. Most importantly, the fibrous roots are short. They grow near the surface of the soil, not deep into the soil.
Answer:
The correct answer is C.
Explanation: If a document for example has bleed, it means that it has to be printed on a large sheet of paper and then it has to be trimmed down.
