Correct Answer: C. involve the use of chemical substances

Correct Answer: D. Cockroach

Correct Answer: A) Cassava

Explanation

This Biology question is asking us to identify which plant stores food in its roots from the given options. The correct answer is option A, which is cassava. Cassava is a tropical root vegetable that is a major staple food in many parts of Africa, Asia, and South America. Cassava is a drought-tolerant plant that can grow well in poor soils, and it is a good source of carbohydrates, fiber, and some essential minerals. The roots of the cassava plant are the main part that is consumed, and they are rich in starch. The roots can be boiled, fried, or roasted and are used to make various dishes such as cassava flour, tapioca, and garri. It is important to note that some other plants also store food in their roots, but they are not among the options provided in this question. For example, sweet potatoes, carrots, and beets are root vegetables that are known to store food in their roots. In conclusion, the correct answer to this question is option A, cassava, which is a tropical root vegetable that stores food in its roots.

Correct Answer: D. Sweat

Correct Answer: B) Chlorophyta

Explanation

This question is asking which of the groups listed is not a major group of the plant kingdom. The options listed are Bryophyta, Chlorophyta, Pteridophyta, Spermatophyta, and Thallophyta. The plant kingdom is divided into several major groups based on their characteristics and features. Bryophyta, Pteridophyta, Spermatophyta, and Thallophyta are all major groups of the plant kingdom. They are characterized by different features such as the presence of flowers, seeds, or vascular tissues. Chlorophyta, on the other hand, is not a major group of the plant kingdom. Chlorophyta is a group of green algae, which are classified separately from the plant kingdom. Green algae share some characteristics with plants, such as the presence of chlorophyll and the ability to carry out photosynthesis. However, they lack some important features that define the plant kingdom, such as the presence of specialized tissues and organs. In summary, the correct answer to this question is Option B: Chlorophyta. Chlorophyta is not a major group of the plant kingdom, as it is classified separately as a group of green algae. For more information on the plant kingdom and its classification, please see the relevant sections of the recommended textbooks.

Correct Answer: A. character are linked

Correct Answer: A) Cytoplasmic membrane

Explanation

The question is asking about the structure in a cell that regulates the movement of substances in and out of the cell. The options provided are Cytoplasmic membrane, Nuclear membrane, Cytoplasm, and Protoplasm. The answer to this question is option A, the Cytoplasmic membrane. Also known as the cell membrane or plasma membrane, it is a thin layer that encloses the cell and regulates the movement of substances in and out of the cell. It is semi-permeable, meaning it allows some substances to pass through while blocking others. The membrane is made up of a phospholipid bilayer with embedded proteins that act as channels or pumps to move substances across the membrane. The Nuclear membrane, option B, surrounds the nucleus of the cell and regulates the movement of substances in and out of the nucleus. The Cytoplasm, option C, refers to the gel-like substance that fills the cell and contains organelles. The Protoplasm, option D, is an outdated term that refers to the entire living content of the cell including the cytoplasm and nucleus. Understanding the function of the Cytoplasmic membrane is important as it plays a vital role in maintaining the internal environment of the cell, which is essential for the cell to carry out its functions.

Correct Answer: D. Missense mutation

Explanation

A missense mutation is a type of point mutation (single base pair change) that alters the codon to the creation of a different protein. A silent mutation is also a point mutation with a change in one base pair, but with the resulting strand still coding for the same protein (hence the term silent). A nonsense mutation changes a codon from coding for an amino acid to coding for termination of the protein. The protein may or may not still be functional depending on how much of it is terminated when the mutation occurs. An insertion is a mutation in which one or more base pairs is added to the coding sequence. Unless the insertion is in a multiple of three (preserving the frame because a codon is made up of three base pairs), it results in a frame shift that alters the reading frame of the codons to the right, causing it to code for a different set of proteins. A deletion is another type of frame shift mutation, in which a base pair (or more) is deleted from the coding sequence, altering the reading frame to code for different proteins in many cases. As with insertions, if the deletion is in a multiple of 3, the frame is preserved as each codon consists of 3 base pairs.
