Correct Answer: A. Abnormally high blood sugar level

Correct Answer: C) Chyle

Explanation

During digestion, food is broken down into smaller molecules that can be absorbed by the body. The process of digestion starts in the mouth where food is chewed and mixed with saliva. The food then moves down the esophagus and into the stomach where it is further broken down by stomach acid and enzymes. After this, the partially digested food, known as chyme, moves into the duodenum, which is the first part of the small intestine. Here, the chyme is mixed with bile from the liver and enzymes from the pancreas to continue the process of digestion. The bile helps to emulsify fats, making it easier for enzymes to break them down. As the chyme passes through the duodenum, it is mixed and churned with these digestive juices, eventually turning into a watery liquid. This watery liquid is called chyle, which is primarily made up of fats and other nutrients that have been broken down by the digestive system. Therefore, the correct answer to the question is option C: Chyle. It is important to note that chyle is not the same thing as chyme, which is the partially digested food that enters the duodenum. It is essential to understand the process of digestion and the role of different organs and enzymes in breaking down food. This knowledge is important in maintaining a healthy digestive system and preventing digestive disorders.

Correct Answer: D) Lowest in the tube with sandy soil

Explanation

Three 30cm lengths of glass tubing are tightly packed with different types of soil (clay, sand, and loamy soil) respectively and stood in a beaker of water for one week. The question is asking what will happen to the level of water in the tubes after one week. The options are: lowest in the tube with clay, the same in all the tubes, lowest in the tube with loamy soil, highest in the tube with sandy soil, and lowest in the tube with sandy soil (which is the correct option). When soil is packed tightly in a tube, it creates small spaces or pores between the soil particles. The size of these spaces varies depending on the type of soil. Sandy soil has larger spaces between particles, whereas clay has smaller spaces. Loamy soil is a mix of sand, silt, and clay and has medium-sized spaces. When the tubes are stood in a beaker of water, the water will move up the tubes through the spaces between the soil particles. However, because the size of the spaces varies between the different types of soil, the rate of water movement will also vary. Since sand has larger spaces between particles, water will move up the tube with sandy soil the fastest, resulting in the highest water level in that tube. On the other hand, clay has smaller spaces between particles, so water will move up the tube with clay the slowest, resulting in the lowest water level in that tube. Loamy soil has medium-sized spaces, so the water level in the tube with loamy soil will be in between the water levels of the tubes with clay and sand. Therefore, the correct option is D, lowest in the tube with sandy soil.

Correct Answer: A. water-soluble

Correct Answer: A. maize gain

Correct Answer: A. able to carry out holozoic nutrition.

Correct Answer: A) chlorophyll and carotenoids

Explanation

Photosynthesis is a process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. This process requires several pigments that absorb light energy and use it to drive the process of photosynthesis. The question is asking about the photosynthetic pigments. According to the options provided, the correct answer is option A: chlorophyll and carotenoids. Chlorophyll is the primary photosynthetic pigment that absorbs light energy and is responsible for the green color of leaves. Carotenoids are accessory pigments that absorb light energy in different parts of the visible spectrum and are responsible for the yellow, orange, and red colors of some fruits and vegetables. Option B is incorrect because chloroplasts and cytochromes are not pigments, but rather organelles and proteins involved in photosynthesis and respiration, respectively. Option C is incorrect because melanin and haemoglobin are not involved in photosynthesis at all, but rather are pigments involved in skin color and oxygen transport in the body, respectively. Option D is incorrect because while carotenoids are indeed a photosynthetic pigment, haemoglobin is not involved in photosynthesis. In summary, the correct answer to the question is option A: chlorophyll and carotenoids. These pigments are essential for the process of photosynthesis, which is how plants and other organisms produce their own food.

Correct Answer: A. thinness in body

Correct Answer: B. nitrogen fixation

Correct Answer: C) Samara

Explanation

In Biology, fruits are the mature ovary of a flowering plant. They usually contain seeds and help the plant in seed dispersal. One type of fruit is the dry indehiscent fruit, which does not split open to release its seeds. This question is asking about a specific type of dry indehiscent fruit formed from one carpel, which is called a samara. A samara is a winged fruit that helps in seed dispersal by wind. The other options listed are Schizocarp, Caryopsis, Nut, and Follicle. Schizocarp is a dry fruit that splits open into separate segments when mature. Caryopsis is a type of fruit where the seed coat is fused with the fruit wall, as seen in grains like wheat and corn. A nut is a hard-shelled fruit that does not split open to release its seeds. A follicle is a dry fruit that splits open along one side to release its seeds. So, the correct answer to this question is option C: Samara, a dry indehiscent, winged fruit formed from one carpel.
