Answer is true because its the closest so far in our galaxy
I would believe tertiary consumer...I'm learning about the same subject...Just...less complicated...
Answer:
Scientists can study tree rings in ice to learn more about past climates.
Explanation:
i think this is right one.
There are multiple characteristic that all dinosaurs shared. Some of the synapomorphies include:
- Vertebrates; skeletons with back bones that surrounds a nerve cord.
- Amniotes; specially adapted for life on dry land.
- Diapsids; two holes located above and behind the eye sockets on each side of the skull.
- Archosaurs; antrobital ferestra, a hole between the nasal hole and the eye socket hole.
But still all of this doesn't separate them from all others, what is unique to them is that all of the 'true dinosaurs' were land dwellers.
Answer:
These are the thylakoids
Explanation:
The thylakoids which contains the chlorophyll is the primary site of photosynthesis. It is covered by layers of cell called the thylakoid membrane.These are the actual site for light dependent reaction.This membrane contains both photosytem I and ii, ATPase enzymes, and Cytochrome b6f complex.While the photosystem i and ii transfer elecrons during photosynthesis, the ATPase enzyme control the catalysis the phosphorylation of ADP to ATP needed for the light independent stage, the Cytochrome proteins acts as the ETC. involved in the transfer of electron during light dependent stage.
When thylakoids are packed together in disc shape they are refer to as Grana,(singular -granum).Each grana are linked together by intergrana.Thus two or more grana are linked by intragrana to form a single photosynthetic functioning unit.The entire structure is bath continuously by the fluid medium-Stroma.
Their stacked and disc shape is to increase the surface area available to accommodate enough ETC, needed to transport electron for chemiosmosis needed for photosynthesis.
