Excretory System is the wastes that gets out of your body by sweat, gas and other types of wastes.Urinary system rids the blood of wastes produced by the cells.
answer:
: D.finding fossils in the same area that are in layers closer to the surface.
Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.
The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion
Cyanobacteria or simply known as blue-green algae may have formed the oxygen into the early atmosphere. This is because these micro-organism has the capability to photosynthesize wherein they can produce oxygen and carbohydrates. In fact, all the plants contribute in the fomation of oxygen.
Answer:
you can see below
Explanation:
Basic Definitions:
Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.
Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.
Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.
Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.
Now Specific Locations:
Eukaryotic cells
have plasma membranes
please mark me brainliest or mark me thanks at leat
only have cell walls if the cells are plants.
They do have a nucleus.
They have cytoplasm
Prokaryotic cells
have plasma membranes
cell walls are usually chemically complexed.
don't have a nucleus
have cytoplasm
Animal cells
only have the plasma membranes.
No cell wall
have a nucleus
have cytoplasm
Plant cells
have both the cell wall
and have a plasma membrane
have a nucleus
have cytoplasm
