- They form in Earth's crust or mantle - intrusive igneous rock.
- They are solid at room temperature - both.
- They are made of molten rocks called magma - intrusive igneous rock.
- They are made of weathered pieces of rock - sedimentary rock.

Answer:
Dorsal nerve cord
Explanation:
For chordates, based on the particular life cycle there are at, they could either posses a NOTOCORD or a DORSAL NERVE CORD.
Chordates can be fishes, reptiles, manmals , vertebrates amphibians, birds etc.
Please let me add that, CHORDATES are mostly if not entirely vertebrates and as such possess DORSAL NERVE CORD.
N.B
Ventral nerve cord are for invertebrates
1. A plant cell has chloroplasts
2. A plant cell has a cell wall
3. A plant cell has vacuoles
An animal cell has none of these features.
Answer:
3) addition of the 7-methylguanosine cap to the 5 end
Explanation:
The 7-methylguanosine (m7G) cap is a modified methylated version of the Guanosine (G) nucleotide which is located on the 5′-terminus of the eukaryotic messenger RNA (mRNA). The m7G cap plays a key role in mRNA translation in eukaryotic organisms, from yeasts to mammals. During mRNA processing, m7G cap is added at the 5' end in order to protect mRNA from degradation by nuclease enzymes. Moreover, this cap also enables the proper attachment of the mRNA molecule to the ribosome during protein synthesis.
