Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
That would be a hypothesis
Hope this helps you :)))
False, because chromosomes are architecturally very compact and genetic code for them, they are not responsible for the specific features we witness.
Contrary to appearance, chromosomes are very compressed physically, allowing for the containment of these enormous DNA structures within the cell nucleus. A human's chromosomes. The genetic code refers to the set of guidelines that living cells employ to convert data from genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. The ribosome does translation by linking genetic code amino acids in the order dictated by messenger RNA (mRNA) and employing transfer RNA (tRNA) molecules to transport amino acids.

Answer:
B. Viruses
Explanation:
Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
