A continent is one of several very large landmasses of the world. Such as North and South America, Australia, Africa, Europe and Asia.
Hope this helps you!

The Correct choices are :
- 1. The elements have filled valence levels.
- 2. potassium (K) with a 1+ charge
To increase the acceleration of the dog sled, increase the applied force on the sled and reduce the mass on the sled.
According to Newton's second law of motion, the force applied to an object is directly proportional to product of mass and acceleration of the object.
F = ma
where;
<em>a </em><em>is the </em><em>acceleration </em><em>of the dog sled</em>

To increase the acceleration of the dog sled:
- Increase the applied force on the sled.
- Reduce the mass on the sled.

Answer:
The correct answer is -
Prokaryotic unicellular -
Eubacteria - is the domain of unicellular organisms that has a prokaryotic cell
Archaebacteria - is one of the two domains of the prokaryotic organisms that are unicellular.
Eukaryotic multicellular (autotroph) -
Plantae - is the multicellular kingdom of the eukaryotic cells and as they produce their own food by photosynthesis called autotrophs.
protists - the autotrophic protists that are multicellular comes under algae, especially red algae.
Eukaryotic multicellular (heterotroph) -
Animalia - The Animalia kingdom is the kingdom of the heterotrophic eukaryotic organism that mostly has multicellular bodies. They depend on plants or other animals for their food.
Fungi - are mostly heterotrophic eukaryotic as they get their nutrient from other organisms are mostly multicellular.
Protist - some protists are heterotrophic as well.
Eukaryotic multicellular/unicellular (heterotroph/autotroph) -
Plantae
protists
Animalia
Fungi
