Correct Answer: D) mitochondrion

Explanation

This question is asking which of the following is not likely to be found in the cell of a ripe tomato fruit. The options are plastids, chlorophyll, cellulose cell wall, mitochondrion, and mineral salts. Plastids are organelles found in plant cells that are responsible for the synthesis and storage of important chemical compounds. Chloroplasts are a type of plastid that contain chlorophyll, which is a pigment responsible for photosynthesis. Cellulose cell walls are found in plant cells and provide structural support. Mitochondria are organelles responsible for producing energy in the cell through cellular respiration. Mineral salts are inorganic compounds that are important for the growth and development of plants. The correct answer to this question is option B: chlorophyll. Chlorophyll is not likely to be found in the cell of a ripe tomato fruit because chlorophyll is responsible for photosynthesis, which occurs in the leaves of the plant. As the tomato fruit ripens, the chlorophyll in the fruit breaks down, resulting in the loss of the green color associated with chlorophyll. In summary, all the options listed are likely to be found in the cell of a ripe tomato fruit except chlorophyll. Chlorophyll is not likely to be found in the cell of a ripe tomato fruit because it breaks down during the ripening process.

Correct Answer: C. cow dung

Correct Answer: D) shark

Explanation

This Biology question is asking which animal is not metamerically segmented. Metamerically segmented means that the animal's body is made up of repeated segments that are similar in structure. The options given are tapeworm, earthworm, centipede, and shark. Tapeworms are flatworms that are parasitic. They have a long, ribbon-like body but do not have segmented bodies, so they are not metamerically segmented. Earthworms, on the other hand, have segmented bodies, which allows them to move efficiently. Each segment has muscles and bristles that help them move through the soil. Centipedes are also metamerically segmented, with each segment having a pair of legs. They are predatory arthropods and use their legs to hunt for prey. Sharks, the correct answer, are not metamerically segmented. Although they have a skeleton made of cartilage and have some repetitive structures, their body is not divided into segments like that of an earthworm or centipede. In conclusion, the animal that is not metamerically segmented is the shark. It is important to understand different body structures of animals as it helps us classify them better.

Correct Answer: B. sexual

Correct Answer: D. autotrophs

Correct Answer: B) Diatom ? crustacea ? ?sh ?man

Explanation

This Biology question is asking us to identify the correct food chain in nature from the given options. A food chain is a series of organisms that depend on each other for food. The organisms are arranged in a particular order such that each organism in the chain feeds on the one before it and is, in turn, eaten by the one after it. Option A suggests that crustacea feeds on diatoms, fish feeds on crustacea and man feeds on fish. This is incorrect because man is not usually part of a food chain in nature. Option B suggests the correct food chain in nature: diatoms are eaten by crustacea, crustacea are eaten by fish and fish are eaten by man. This is a correct food chain in nature. Option C suggests that fish feeds on crustacea, crustacea feeds on man and man feeds on diatoms. This is incorrect because it is not usually the case that higher organisms such as man feed on lower organisms in a food chain. Option D suggests that diatoms are eaten by fish, fish are eaten by crustacea and crustacea is eaten by man. This is incorrect because it is not usually the case that higher organisms such as man feed on lower organisms in a food chain. Thus, the correct answer is Option B, which represents a correct food chain in nature.
