Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. ...Digestive juices contain enzymes that break food down into different nutrients.
Answer:
DNA was discovered in 1869 by Swiss researcher Friedrich Miescher, who was originally trying to study the composition of lymphoid cells (white blood cells). Instead, he isolated a new molecule he called nuclein (DNA with associated proteins) from a cell nucleus.
Explanation:
An increase in a predator population would decrease the prey species, since there are more hungry wolves to eat more prey. Look at your food web and find what the wolves are feeding on, this species would decrease. If there’s anything feeding on the wolves, they would increase since now they have a larger population of their prey species.
True. The highest mountain in the world is Mauna Kea in Hawaii. The base of Mauna Kea is underwater, and it rises above sea level.
Answer:
Urochordata
Explanation:
Chordata is an animal phylum characterized by four features at some point in their lifetime. These four features are:
- notochord
- pharyngeal slits
- dorsal hollow nerve cord
- post-anall tail
Chordata is further divided into urochordata, cephalochordata and vertebrates.
Urochordates display all the four features of chordates in their larval form but their adult form has none of them except pharyngeal slits. They also change from their free swimming larval form to sessile adult form which means that they attach to a surface unlike the larval form. They also display filter feeding i.e. their food is filtered via the pharyngeal slits. Since all these characteristics are being displayed by the newly discovered species, it belongs to urochordata group.
