Correct Answer: A) Homoiothermic

Explanation

This Biology question is asking about animals that do not change their body temperature with their surroundings. These animals are called either poikilothermic or homoiothermic. Poikilothermic animals are those whose body temperature changes with the temperature of their surroundings, while homoiothermic animals maintain a constant body temperature regardless of the temperature of their surroundings. The correct answer to this question is option A, homoiothermic. Homoiothermic animals, also known as endothermic animals, are able to maintain a constant body temperature through internal thermoregulation mechanisms such as sweating, panting, shivering, or adjusting their metabolic rate. This allows them to live in various environments and climates without their internal temperature being affected. Some examples of homoiothermic animals include mammals and birds. On the other hand, poikilothermic animals, also known as ectothermic animals, rely on external factors such as sunlight or shade to regulate their body temperature. Their body temperature fluctuates along with the temperature of their surroundings. Some examples of poikilothermic animals include reptiles, amphibians, and fish. In summary, animals that do not allow their body temperature to vary with the ambient are called homoiothermic or endothermic animals, and they are able to maintain a constant body temperature through internal thermoregulation mechanisms. The correct answer to this question is option A, homoiothermic.

Correct Answer: A. digesting its food extra cellularly

Correct Answer: D. Osmosis

Correct Answer: D) B

Explanation

Beriberi is a disease that is caused by a deficiency of a particular vitamin. The question is asking us to identify the specific vitamin that causes beriberi. From the options given, we have vitamin A, D, K, and B. We need to select the correct vitamin that causes beriberi. The correct answer is option D, which is vitamin B. Beriberi is caused by a deficiency of thiamine, which is also called vitamin B1. Thiamine is important for the proper functioning of the nervous system and the heart. It is found in foods such as whole grains, meat, fish, beans, and nuts. It is important to note that there are different types of beriberi, such as wet beriberi and dry beriberi, and they can affect different parts of the body. Wet beriberi affects the cardiovascular system, while dry beriberi affects the nervous system. Severe thiamine deficiency can also lead to a condition called Wernicke-Korsakoff syndrome, which affects the brain and can cause memory loss and confusion. In conclusion, the correct vitamin that causes beriberi is vitamin B or thiamine. It is important to eat a balanced diet that includes sources of thiamine to prevent deficiency and the associated health problems.

Correct Answer: D. Syphilis

Correct Answer: A. stigma, style and ovary

Correct Answer: D. Nastic movement

Correct Answer: D. oxygen

Correct Answer: B. Water in ponds and swamp

Correct Answer: B. Lipids and glycogen

Explanation

Both lipids (fat) and glycogen (made up of glucose molecules) store energy in animals. Lipids are used for long-term energy storage while glycogen, found in the liver and muscles, is used for short-term energy storage. Peptidoglycan is the molecule that makes up the bacterial cell walls.
