Sedimentary
Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contains fossils.
Examples of this rock type include conglomerate and limestone.
Metamorphic
Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). The rocks that result from these processes often have ribbonlike layers and may have shiny crystals, formed by minerals growing slowly over time, on their surface.
Examples of this rock type include gneiss and marble.
Igneous
Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals form and the rock looks shiny and glasslike. Sometimes gas bubbles are trapped in the rock during the cooling process, leaving tiny holes and spaces in the rock.

The rabbit cell is an animal cell. It has a two layered lipid membrane. The lipid membrane is non-polar in nature and will permit the movement of non-polar substrates across itself. Ions and large charged particles cannot pass across this membrane unless the cell expends its store of energy to facilitate their active transport into the cell. Hence Calcium ions and sodium ions will not diffuse across the rabbit cell membrane, whereas water (uncharged), glucose (polar) and oxygen (uncharged) will diffuse across the lipid membrane.
Answer:
- Chimpanzee : probes to obtain insects, Spears to kill bush babies
- Capuchin monkey : stones for nut cracking, stones used to dig for food
Explanation:
The Chimpanzee are a type of Mammals known to be very strong from the age of Five. they hunt down other larger mammals using spear and stones. it has been observed in Africa when Chimpanzees were making spear out of sticks in order to kill bush babies in the forest.they also use twigs to probe /obtain insects.
Capuchin monkeys are a type of monkey with similar characteristics with other types of Monkeys who live in the wild, they eat fruits and nuts and they used stones to dig up hard to get food from the ground and from back or roots of trees.
The doctor examined her external ear canal and tympanic membrane with an otoscope. An otoscope is an instrument used to visually examine the external ear canal and tympanic membrane. Eardrum or tympanic membrane is a thin layer of tissue in human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles, which are tiny bones in the tympanic cavity.
True. The Esophagus is the alimentary canal of the human body in which digestion does not occur. The alimentary canal is the where the food travels that starts from the mouth unto the anus. When the food enters the mouth, digestion already starts. Food only travels in the esophagus to the stomach.
