Answers
Answer:
1)Burr or also spelt as Bur are seeds of plants, which have spikes around them and these spikes are slightly bent towards their end, which make them easier to attach them to the furs or coats of animals or clothes of human beings.
2)Shearing doesn't usually hurt a Sheep. It is just like getting a hair cut.However, shearing requires skill so that the sheep is shorn efficiently and quickly without causing cuts or injury to the Sheep or shearer.The uppermost layer of the skin is dead.
3)The stomach is the main food storage tank of the body. If it were not for the stomach’s storage capacity, we would have to eat constantly instead of just a few times each day. The stomach also secretes a mixture of acid, mucus, and digestive enzymes that helps to digest and sanitize our food while it is being stored.
4)Gastric mucus is a glycoprotein that serves two purposes: the lubrication of food masses in order to facilitate movement within the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity.
5)Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
Answer:
1, A burn is a damage to skin or deeper tissues
2, Just like a hair cut , Shearing also does not hurt the sheep . It is the upper most layer of the skin of sheap which is usually dead
3, The innermost lining of the stomach secretes mucus , hydrochloride acid as well as a certain types of digestive enzymes ti digest or breakdown the food present in the stomach
4, Gastric mucus is the glycoprotein that serves two proposes : the lubrication of food mass in order to facilitate movement with in the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity
5, Chlorophyll jobs in a plant is absorb light - usually sunlight . The energy absorbed by light is transferred ti two kinds of energy - storing molecules . Through Photosynthesis plants uses the stored energy ti convert carbon dioxide and water into glucose , A TYPE OF SUGAR
