Answer:A herbivorous duck
Explanation:A primary consumer is an organism that eats producers. Primary consumers are always herbivores.
As humans sometimes experience, a cold environment can result in<span> </span>shivering<span>. This is when skeletal muscles begin to shake in small movements, creating warmth by expending energy. Humans can also sweat in high temperatures. The water on the surface of the skin is able to absorb a lot of heat during evaporation, resulting in cooling of the body.</span>
<span>This is speciation. In this process, two distinct species are formed through the intervention of some means such as differing environments or locations. This is done typically as a way of staying evolutionarily competitive in the area in which the species resides. The new species would be the exemplar of that which is best suited to the new conditions.</span>
Answer:
1) Organisms in this domain can be unicellular or multicellular - Eukarya
2) Organisms in this domain are unicellular and are often found in extreme environments - Archaea
3) Organisms in this domain have cells that contain a nucleus - Eukarya
Explanation:
All living organisms were classified into a large group consisting of three types of organisms called DOMAIN. It is the highest taxonomic rank of organisms. The three domains that life was classified into are: Archaea, Bacteria and Eukarya.
The domain Archaea contains organisms that are unicellular and prokaryotic i.e. they do not have a membrane-bound nucleus. The organisms in this domain are characterized by their ability to survive in harsh environmental conditions e.g hot temperatures etc
The domain Bacteria also consists of unicellular and prokaryotic organisms. They contain cell walls in their cells made up of peptidoglycan unlike domain Archaea and Eukarya.
The domain Eukarya consists of organisms that are both unicellular and multicellular and strictly eukaryotic i.e. possess a membrane bound nucleus that houses their genetic material. They are divided into Kingdoms: Protista, Plantae, Animalia and Fungi.
