Biologists suspect that endosymbiosis gave rise to mitochondria before plastids partly because
a. mitochondrial proteins are synthesized on cytosolic ribosomes, whereas plastids utilize their own ribosomes.
b. mitochondrial dna is less similar to prokaryotic dna than is plastid dna.
c. the products of photosynthesis could not be metabolized without mitochondrial enzymes.
d. all eukaryotes have mitochondria (or their remnants), whereas many eukaryotes do not have plastids.
e. without mitochondrial co2 production, photosynthesis could not occur.

What is earths lithospheric plates interact at

This is a type pf behavior that animals are born with and them to survive

1. seamount a raised footwall block between normal fault creates this 2. syncline break between rocks where a hanging wall rises relative to a footwall 3. hot spring on rolling hills, this a dip between hills 4. volcanic neck created when a block with hanging walls slips down between normal faults 5. caldera underwater volcano that never reaches above sea level 6. horst natural hot water on earth's surface containing many minerals 7. graben underwater volcano whose top is eroded flat by waves 8. crater less than a mile in diameter; looks like a bowl at the top of a volcano 9. guyot magma that filled the central vent that remains after the volcano has eroded 10. reverse fault over 1 mile in diameter; looks like a bowl over a volcano
