It is the rib cage (thoracic cage)
They build up in the thylakoid, where they bond to each other to create ATP.
Not 100% about this but that's what i got.
B. larger and more complex
Explanation: As the environment became more unpredictable, bigger brains helped our ancestors survive.
If the organism are of a similar species then it would be a population.
To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene.The DNA housed in the nucleus is too large to move through the nuclear membrane, so it must be copied by the smaller, single-stranded RNA (transcription), which moves out of the nucleus to ribosomes located in the cytoplasm and rough endoplasmic reticulum to direct the assembly of protein (translation).
