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.

Grams are very exact and meters are also common to use.
DNA helicase untwists the helix at the replication origins. Then the DNA is seperated into a "Y" shape called the replication fork.
Answer:
a monocot
Explanation:
Monocotiledoneas are plants that develop from a seedling with a single cotyledon. That is why we can say that maize is a monocotyledon.
Monocotyledons and dicotyledons are two classes of vegetables that belong to the angiosperm plants (plants with seeds contained within the fruits) and also phanerogams (flowering plants), currently classified as magnoliophytes, gathering approximately 230 thousand species. Monocotyledons are plants that have only one cotyledon in the seed. Cotyledons are the initial leaves of plant embryos.

Explanation:
The best shelling opportunities tend to happen during low tide, where the shells that are normally covered by water are left exposed on the sand.
