Answer:
84.8% scrotium is present in 2.89g scrotium oxide
Explanation:
Mass percent of an element is the percentage product of the mass of the element divided by the mass of the compound formed by the interaction of the element with other elements.
Mathematically,
% of Sr element = mass of scrotium/ mass of scrotium oxide * 100%
% of Sr = 2.45g / 2.89g
% of Sr = 0.8477g of 100%
= 84.8% of scrotium.
Encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.

Answer: Extinction
Animals on the verge of extinction are considered endangered species. Some could argue that the phrasing "threatened" is synonymous to "endangered". Some classify extinction based on if the species is completely wiped out in the wild, or if the species is completely gone (both in the wild and in zoos for instance). Extinction events are not solely due to the changes in atmosphere, but also due to lack of food or habitat, among other possible factors.
