In biological taxonomy, the next smallest classification group after Order is Family. This is part of the classification system that ranges from broad categories to more specific ones, which include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
In the biological classification system, the next smallest group after Order is Family. This refers to the hierarchy of taxonomic ranks in biology, where organisms are classified from broad categories to more specific ones. The sequence of ranks from broad to specific is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each rank gets more specific as you go down the list. So, if you're looking at the rank just beneath Order, it would be Family. For instance, in the Order Carnivora (carnivores) one of the Families is Felidae (cats).

Answer:
= 25 g
Explanation:
Using the formula;
A = A₀ (1/2)^(t/h)
where A is the final amount,
A₀ is the initial amount of the substance,
t is the time and
h is the half-life of the substance,
In this case; the half life of U-238 h is equal to 4.47 billion years.
A = A₀ (1/2)^(t/h)
A = 50 (1/2)^(4.5 / 4.47)
= 24.88
= 25 g
Answer:
C) 25 grams
Explanation:
25 grams would remain after one half-life (4.5 billion years). Find the point where percent remaining is 50% and that will tell you it is one half-life.
B) steel rusting
C) paper burning
D) wood decaying
A physical change changes the state on object is in, making the answer A) iron melting. Since it's melting, it's going from solid to liquid.
