With each contraction cycle, actin moves relative to myosin. ... ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur. Therefore, without ATP, muscles would remain in their contracted state, rather than their relaxed state.
Fat is the nutrient needed as an energy store and insulation.
The two major surviving clades of diapsids include modern animals like snakes, lizards, crocodiles, and birds
A clade is a branch in a cladogram that has a single common ancestor with all of its offspring. An evolutionary tree that depicts the relationships between species' ancestors is called a cladogram. In the past, cladograms were created using similarities among species' phenotypic or physical characteristics.
All hominoids, including humans, chimpanzees, gorillas, orangutans, and gibbons, are members of this group. The Hominoid clade is a subgroup of the Anthropoids, a broader clade that includes Old World and New World monkeys. The use of a phylogenetic tree makes clade identification simple. Just visualize pruning even one branch from the tree.
