Both plant and animal cells have mitochondria
The answer is B) 4IF3 Hope this helps!
Aye Sir!
Cohesive. This means that the water is attracted to other particles of itself, so they stick and bead up.
Answer:
Protein production in prokaryotes begins even before the completion of transcription. This means that ribosomes attach to the mRNA being generated even before transcription process is terminated. Therefore translation occurs in concurrence with transcription. This is because there is no definitive boundary between the nucleoid and cytoplasm.
In eukaryotic cells, the nucleus is separated from the cytoplasm by the nuclear membrane. This means transcription has to complete before the translation of proteins occurs. This is because the ribosomes are located in the cytoplasm while the DNA is in the nucleus.
This difference is part of the reason prokaryotic cells are able to respond really fast to an environmental stimuli as compared to eukaryotes. Remember in addition mRNA in prokaryotes do not need splicing (as required in eukaryotes) adding to quick protein production.

Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.
