Answer: The spiny lobster belongs to the kingdom ANIMALIA while diatoms belongs to the kingdom PROTISTA.

Explanation:

There are different ways biologists have used to examine and describe million kinds of living organisms. To classify organisms into groups, biologist look for important features that are shared by a large variety of organisms. These features which should have similar origin, structure and position. Organisms with certain important features in common are then put together into one group.

In the hierarchy of living organisms, the largest group of organisms is the KINGDOM. There are five types of kingdoms in which organisms are grouped, these includes:

--> kingdom Monera

--> kingdom PROTISTA,

--> kingdom fungi,

--> kingdom plantae and,

--> kingdom ANIMALIA.

Kingdom PROTISTA: they are single-celled, motile or non-motile organisms that are made up of eucaryotic cells, that is,cell structure is complex with a definite nucleus. Member include the DIATOMS, amoeba and chlamydomonas.

Kingdom ANIMALIA: They are multiple-celled, motile organisms that feed on other organisms. Their cells have no cell walls. The members include the SPINY LOBSTER, corals,worms, snails and cows

Ammonia, nh3, is a weak base with a kb = 1.8 x 10-5. in a 0.8m solution of ammonia, which has a higher concentration: ammonia (n
insens350 [35]
Answer is: concentration ammonia is higher than concentration of ammonium ion.
Chemical reaction of ammonia in water: NH₃ + H₂O → NH₄⁺ + OH⁻.
Kb(NH₃) = 1,8·10⁻⁵.
c₀(NH₃) = 0,8 mol/L.
c(NH₄⁺) = c(OH⁻) = x.
c(NH₃) = 0,8 mol/L - x.
Kb = c(NH₄⁺) · c(OH⁻) / c(NH₃).
0,000018 = x² /  0,8 mol/L - x.
solve quadratic equation: x = c(NH₄⁺) = 3,79·10⁻³ mol/L.

DiKsa [7]

Answer:

See explaination

Explanation:

The invariant mass of an electron is approximately9. 109×10−31 kilograms, or5. 489×10−4 atomic mass units. On the basis of Einstein's principle of mass–energy equivalence, this mass corresponds to a rest energy of 0.511 MeV.
