Answer:
The four organelles that contribute to the synthesis, transport, packaging, and export of proteins to the extracellular environment are Nucleus, RIBOSOMES, rough endoplasmic recticulum and Golgi apparathus.
Explanation:
The nucleus is the organelle that produced RIBOSOMES.
RIBOSOMES are organelles responsible for protein synthesis production of proteins.
The protein produced by the RIBOSOMES are then gathered in the rough endoplasmic recticulum . It then export and transport the protein to Golgi apparatus. The Golgi apparatus modifies and package the protein.
Hey do you still need the answer i have the first one but im still working on the rest im in k12 to xD
1) *The
oldest rock layers of rocks are found on the bottom, well the youngest rocks
are found on top. The different colors of these layers are caused by many different
minerals and materials and a main two of the main rolls are iron and climate
that is what i have for the first one
The reason why sharks can swim fast is that unlike most fish, sharks have tails that are not horizontally symmetrical . Instead , the top of a shark's tail protrudes further back than the bottom , giving the shark lift while swimming and making it "spring" forward at speed.
Most fish make a single water "ring" that moves backward at the end of their tail's stroke but sharks are thought to produce two rings because of their asymmetrical tail which bespeaks a more efficient propelling action.
It has also been discovered that sharks can raise the tiny teeth-like structures called placoid scales on their skin to create tiny wells across the surface of their skin which reduces drag just like the dimples on a golf ball, thus enabling the shark move forward faster.
No nucleus, they are prokaryotes
Rapid burial and the possession of hard parts.
