Correct Answer: D. Both parents possess gene for shortness

Correct Answer: A) photosynthesis

Explanation

The fossil fuels include coal, natural gas and the products from the fractional distillation of crude oil, such as petrol and diesel. When any fossil fuel is burned, one of the combustion products is carbon dioxide. This has led to an increase in the percentage of carbon dioxide in the air. Thus, burning of fossil fuels add carbon dioxide to the biome. The answer should be photosynthesis because the byproduct of photosynthesis is oxygen and not carbon dioxide.

Correct Answer: D. Progressive decrease in the number of individuals from lower to higher trophic level

Correct Answer: A. vivparous mode of reproduction

Correct Answer: C. ventricles pump blood to longer distances

Correct Answer: C)Mitochondrion

Explanation

This question is testing your knowledge of the components of a cell nucleus. The nucleus is the control center of the cell and contains several important structures. The question is asking which of the following structures is NOT present in the nucleus of a cell. The options given are chromosomes, nucleolus, mitochondrion, and genes. Chromosomes are thread-like structures that carry genetic information, and they are present in the nucleus of a cell. The nucleolus is a dense region within the nucleus that is responsible for producing ribosomes, and it is also present in the nucleus of a cell. Genes are specific segments of DNA that provide instructions for the development and functioning of an organism, and they are located on the chromosomes within the nucleus. The correct answer is option C, mitochondrion. Mitochondria are organelles that are responsible for producing energy in the cell through a process called cellular respiration. They are not present in the nucleus of a cell, but rather in the cytoplasm outside of the nucleus. Therefore, mitochondrion is not a component of the nucleus. In summary, the correct answer to this question is option C, mitochondrion, which is not present in the nucleus of a cell.

Correct Answer: A. erythrocytes

Correct Answer: D) an anemometer

Explanation

An anemometer is an instrument used to measure the speed of wind. It is a device that has cups that spin when the wind blows. The faster the wind blows, the faster the cups spin. The anemometer then calculates the wind speed based on the speed of the spinning cups. It is important to measure wind speed in various fields such as aviation, weather forecasting, and even sports. Wind speed affects the flight of planes, the accuracy of weather predictions, and the performance of athletes. The other options listed - a barometer, a wind gauge, a wind vane, and a hydrometer - are instruments used for other purposes and are not used to measure wind speed. Therefore, the correct option for the instrument used in measuring the speed of wind is option D, an anemometer.

Correct Answer: C. tall plants and short plants are crossbred

Correct Answer: C) fat droplets

Explanation

This Biology question is asking which of the following is not a cell organelle. The options given are golgi body, nucleus, fat droplets, ribosome, and endoplasmic reticulum. A cell organelle is a specialized structure within a cell that performs a specific function. Option A, golgi body, is a cell organelle that processes and packages proteins and lipids. Option B, nucleus, is also a cell organelle that contains the genetic material of the cell. Option D, ribosome, is an organelle responsible for protein synthesis. Option E, endoplasmic reticulum, is an organelle involved in protein synthesis and lipid metabolism. Option C, fat droplets, is not a cell organelle. Fat droplets are stored in cells as a source of energy. They are not specialized structures with specific functions like the other organelles mentioned in the options. Therefore, option C is the correct answer to this question. It is important to note that although fat droplets are not considered cell organelles, they are still important components of cells and play a vital role in energy storage and metabolism.
