Protists are unicellular eukaryotes, whereas Eubacteria and Archaebacteria are unicellular prokaryotes.
Eubacteria and Archaebacteria belong to kingdom Monera; whereas Protists belong to kingdom Protista.
All Monerans have prokaryotic cell structure. Protists have eukaryotic cell structure and are unicellular.
Protists either lack cell wall or have cell wall made up of cellulose.
Eukaryotes have cell wall made up of peptidoglycan or murein.
In Archaebacteria cell wall lacks peptidoglycan but contains proteins and non-cellulosic polysaccharides.
Protists have typical sexual reproduction involving fusion of gametes. In Eubacteria and Archaebacteria typical sexual reproduction is absent.
Cell division is mitotic type in Protists and amitotic in Eubacteria and Archaebacteria.
A first quarter to a full moon
Answer:
Explanation:
Lower frequency for both dewlap extension and pushups. In the presence of predators and females an increase in the dewlap frequency and pushups is expected as a result of defense and breeding mechanisms mixed while in the second situation we have just breeding mechanisms involved
Fatty substances such as cholestrol and saturated fats may be deposited on the inner surface of the coronary arteries. This narrows the lumen of these arteries and increases blood pressure. Such an affected artery develops a rough inner surface. This increases the risk of a blood clot being trapped in the artery. A blood clot that forms in an artery is called a thrombosis. Blood supply to the heart muscles can be greatly reduced due to the blockage of the coronary arteries. This can cause a heart attack. Hope this helps!
Fault-block mountains are formed by extensional stresses.
Explanation:
- Fault-block mountains are formed because of extensional stresses. They are also called tension stresses.
- These stresses pulls and stretches rocks apart which causes normal faults to form.
- The normal fault cuts through rocks, causing one to slip downward and one to move upward. Thus, fault-block mountains are formed.
- Sierra Nevada in California and Nevada is an example of a fault-block mountain.
