<span>hydrocyanic acid is the correct answer</span>
Answer:
young
Explanation:
Most crust in the ocean basins is less than 200 million years old, which is much younger than the 4.54 billion year age of the Earth. This fact reflects the process of lithosphere recycling into the Earth's mantle during subduction.
Answer: Option D
Explanation:
The embryonic induction can be defined as the critical part in formation of the other tissues and organs because one cells affects the development of the other cells.
In vertebrates the notochord arises from the dorsal organiser, in amphibian the organizer is a region of vertebrate gastrulae which is when transplanted into the ventral region of the host embryo stimulates the formation of second embryonic axis and neural tube in embryo.
This generation of second notochord in the an example of influence of one group of cell on other.
Answer:
The correct answer is C) selective transport through nuclear pore complexes
Explanation:
Nucleus is the place where the replication and the transcription of DNA occurs. The process of translation in eukaryotes occurs in cytoplasm therefore RNA has to come out of the nucleus.
Nuclear pore complexes are the openings in the nuclear membrane from where these molecules come out in the cytoplasm. Small RNA like tRNA directly comes out through binding directly to export receptors but large RNA like mRNA forms ribonucleoprotein particles which involves class-specific adaptor proteins for transport. So the right answer is C.
