Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.
The answer is a low-density particle
Atom refers to a tiny particle, which is the basic building block of all the substances and whose properties determine the characteristics of an element made up of only of those atoms.
All the living and nonliving matter in this world are made up of atoms and elements. Everything in the universe is matter, and matter comprises elements. Some of the elements are important to living things.
Elements are formed by atoms, and atoms comprise protons, electrons, and neutrons. The number of protons in an element's atom signifies the identity of the element.
