Essential Knowledge
It is essential that the student be able to distinguish between specialized structures that allow protists and fungi to obtain energy and explore their environment.
Protists
Protists are organisms that are classified into the Kingdom Protista. Although there is a lot of variety within the protists, they do share some common characteristics.
● Protists are usually single celled organisms.
● Live in moist environments.
● Vary in the ways they move and obtain energy.
Protists obtain their energy in several ways.
● Animal-like protists ingest or absorb food after capturing or trapping it.
● Plant-like protists produce food through photosynthesis.
● Fungus-like protists obtain their food by external digestion either as decomposers or as parasites.
● Some protists have both autotrophic and heterotrophic characteristi
Answer:
The dimension is L
Explanation:
Dimension analysis is a method of representing quantities majorly with respect to some fundamental quantities of mass (M), length (L), time (T).
A sphere has a definite volume which relates to its radius by:
V = 
In this equation is a dimensionless quantity, and the unit of v is 
.
But, metre is a measure of length, thus it has a dimension of L.
So that,
≅ 
Then,
=
Find the cube root of both sides to have,
r = L
Therefore, the dimension of the radius of a sphere is L.

Answer:
The apple
Explanation:
The apple has gravitational potential energy because it is just sitting there but nothing is pushing it up, it is not sitting on something. This means that it has a lot of gravitational potential energy as nothing is pushing it up.
