Ques:Q: What controls the shape of a developing zygote early in its development?   Read this paragraph and choose the correct option from the provided answers:  Gap genes control the shape of a developing zygote early in its development. Gap mutants are missing segments in their embryos. These genes are highly regulated.   Choices:  - chromosomes  - storage genes  - DNA  - gap genes   A:

Ans:gap genes

Ques:Q: What is the message sent from the nucleus to the ribosome?   Read this paragraph and choose the correct option from the provided answers:  The mRNA is the message sent from the nucleus to the ribosome, the organelle of protein synthesis. Like a foreign language, the genetic code of the mRNA message must then be translated so that the ribosomes make the correct protein. The process of reading the code of a mRNA to make a protein is called translation.   Choices:  - dna  - mitochondria  - rna  - mrna   A:

Ans:mrna

Ques:Q: Which is one of the most complicated parts of gene regulation in eukaryotic cells?   Read this paragraph and choose the correct option from the provided answers:  In eukaryotic cells, the start of transcription is one of the most complicated parts of gene regulation. There may be many regulatory proteins and regulatory elements involved. Regulation may also involve enhancers. Enhancers are distant regions of DNA that can loop back to interact with a gene’s promoter.   Choices:  - middle of transcription  - aftermath of transcription  - end of transcription  - start of transcription   A:

Ans:start of transcription

Ques:Q: Steam actually consists of tiny droplets of liquid what?   Read this paragraph and choose the correct option from the provided answers:  Steam actually consists of tiny droplets of liquid water. What you can’t see in the picture is the water vapor that is also present in the air above the spring. Water vapor is water in the gaseous state. It constantly rises up from the surface of boiling hot water. Why? At high temperatures, particles of a liquid gain enough energy to completely overcome the force of attraction between them, so they change to a gas. The gas forms bubbles that rise to the surface of the liquid because gas is less dense than liquid. The bubbling up of the liquid is called boiling. When the bubbles reach the surface, the gas escapes into the air. The entire process in which a liquid boils and changes to a gas that escapes into the air is called vaporization .

Choices:  - lead  - methane  - mercury  - water   A:
