Correct Answer: C. pleural membrane

Correct Answer: B) cell wall and chloroplast

Explanation

In Biology, there are different types of cells with different structures. The question is asking which two structures are present in a palisade cell but not in a liver. Palisade cells are found in plant leaves and are responsible for photosynthesis. The liver, on the other hand, is a vital organ in animals responsible for detoxification, protein synthesis, and many other functions. The options given are cell wall and cytoplasm, cell wall and chloroplast, cell membrane and cytoplasm, and cell membrane and chloroplast. The correct answer is option B, which states that cell wall and chloroplast are present in palisade cells but not in the liver. The cell wall is a rigid layer that surrounds plant cells, providing support and protection. Chloroplasts are organelles found in plant cells responsible for photosynthesis, the process of converting light energy into chemical energy. Palisade cells are specialized for photosynthesis; hence, they have chloroplasts, while the liver does not need chloroplasts since it has no role in photosynthesis. To sum up, the correct answer to the question is option B, which states that cell wall and chloroplast are present in a palisade cell but not in a liver.

Correct Answer: B. superior ovary

Correct Answer: C. Males are usually carriers

Correct Answer: B) taste buds

Explanation

The question is asking about the groups of sensory cells found on the upper surface of the tongue. These cells are responsible for our ability to taste different flavors, and they are called taste buds. Therefore, the correct answer is option B. Taste buds are small clusters of cells found on the tongue, as well as the roof of the mouth and back of the throat. They contain specialized cells called gustatory cells, which are responsible for detecting different flavors. Taste buds can detect five basic tastes: sweet, sour, salty, bitter, and umami (savory). It's important to note that taste buds are not the only cells involved in our sense of taste. The process of tasting involves a complex interaction between taste buds, olfactory (smell) receptors, and other sensory cells. Our sense of taste is also influenced by factors such as texture, temperature, and even our emotional state. In conclusion, taste buds are the groups of sensory cells found on the upper surface of the tongue responsible for our sense of taste. They contain gustatory cells that detect different flavors, and work in conjunction with other sensory cells to create our sense of taste.

Correct Answer: A. protect endangered species

Correct Answer: B. Layering

Correct Answer: A) can see near objects clearly

Explanation

This question is asking about myopia, a condition that affects vision. The question is asking what people with myopia can or cannot see clearly. Myopia is also known as nearsightedness. It is a condition where a person can see objects that are close to them clearly, but objects that are far away appear blurry and out of focus. This means that Option A, which states that people with myopia can see near objects clearly, is the correct answer. In contrast, Option B states that people with myopia can see far away objects clearly. This is incorrect as myopia causes difficulty in seeing distant objects. Option C states that people with myopia cannot see any object clearly. This is also incorrect as people with myopia can see objects that are close to them clearly. Option D states that people with myopia are colourblind. This is not related to myopia and is therefore incorrect. To summarize, people with myopia can see near objects clearly but have difficulty seeing objects that are far away.
