HI Mate! The right answer is vascular tissue!
Star brightness is defined by either <span>D. apparent magnitude - when we measure it from Earth (that is how bright it is from Earth) - this is the closest to "basic observation" and the best answer
or by absolute magnitute - how bright it would be at a certain distance (this allows to compare the brightness).

(I couldn't see the last few, so.)
Supercoiling is an important property of DNA tertiary structure that affects essential processes such as replication and transcription. Negative supercoiling is very important. Negative supercoiling causes unwinding of DNA and it makes the DNA strand ready for biological processes such as replication and transcription. Negative supercoiling is introduced in a DNA with the help of enzyme topoisomerase enzymes I and II. In bacteria topoisomerase enzyme II is called gyrase.
