Answer:
Most kingdoms are Eukaryotic
Explanation:
Prokaryotes are organisms consisting of cells that do not have membrane-bound organelles or a cell nucleus.
Eukaryotes are organisms made up of cells that have a membrane-bound nucleus to hold their genetic material, in addition to membrane-bound organelles.
The five kingdoms are Animalia, Plantae, Protista, Fungi, and Monera.
Animalia are eukaryotic because the organisms in this category are advanced organisms that require membrane-bound organelles and a nucleus with their genetic DNA in order to function and thrive. Protista, fungi, and plantae also go into the eukaryotic category because protists, fungi, and plants all have membrane-bound organelles and can carry out higher-level functions.
Monera are prokaryotes, and monera are usually classified into two domains: bacteria and archaea. Monerans lack a nucleus and membrane-bound organelles, and for this reason Monerans are very small organisms.
Answer:
The answer is below
Explanation:
The half life of a substance is the time required by that substance to reduce to half of its initial value. The half life is calculated using the formula:
Given that t = 87 years, half life = 29 years, therefore the quantity of strontium-90 left is:
That is one-eight of Strontium 90 would be left after 87 years
