Answers
Answer:
1. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. ... Ruminant animals do not completely chew the grass or vegetation they eat.
2. Incisors are the teeth that you use to bite into your food. Canines - Your canines are the next teeth that develop in your mouth. You have four of them and they are your sharpest teeth, used for tearing apart food. Premolars - Premolars are used for tearing and crushing food.
3. The life cycle of silk moth starts when a female silk moth lays eggs. The caterpillar or larvae are hatched from the eggs of the silk moth. The silkworms feed on mulberry leaves and give rise to pupa. In the pupa stage, a weave is netted around by the silkworm to hold itself.
4. A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.
5. An acid is a substance that produces hydrogen ion (H+) as the only positive ion when mixed with water. A base is a substance that produces hydroxyl ion (OH–) as the only negative ion when mixed with water. An acid is a species that can release/donate a proton to another species.
6. In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
