Muscles are the tissue structures that move bones. They are connected to bones and need proteins to grow and stay healthy.

Answer is Muscles.

Muscles work on contraction. Muscles can only pull and cannot push. This means that a muscle can only move a bone in one direction and there is no way to move the bone back again. This problem is solved by having muscles in pairs, called antagonistic muscles. The antagonistic muscles work in pairs. One muscle contracts while the other relaxes.

For example, the lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed. To lower the forearm again, the triceps contracts and the biceps relaxes.

what is a mass extinction? what is a mass extinction? an event that causes the extinction of a large fraction of earth's species
sineoko [7]

A mass extinction event occurs when a species disappears far more quickly than it is replaced. This is typically understood as the loss of around 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.

An enormous number of species were wiped out by a harsh, worldwide, swift, and selective event is mass extinction. According to marine fossils, at least 75% of all species are thought to have become extinct. The most recent mass extinction is the Cretaceous-Paleogene extinction event, which is also the only one that can be proven to have been caused by a significant asteroid impact. All non-avian dinosaur species, making up about 76 percent of all species on the earth, perished during mass extinction. The Chicxulub asteroid impact in what is now Mexico, which occurred 66 million years ago, caused an ecosystem collapse that resulted in the extinction of the dinosaurs and >75% of all land and sea species as well as the macroevolution of mammals.

Explain why most farmers use stem cuttings to plant new fruit trees rather than plant seeds.
Dvinal [7]

The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
