Austin and Marissa hypothesize that coneflower stomata use feedback loops to respond to moisture levels by opening when there is

moisture present, and closing when there is no moisture present. Which BEST describes the setup they should use to support their hypothesis?
A
Austin and Marissa should observe the number of closed stomata on one leaf, mist the leaf with water, wait one hour, and count the total number of stomata.

B
Austin and Marissa should observe the number of stomata on one leaf, mist the leaf with water, wait one hour, and count the number of stomata that have grown.

C
Austin and Marissa should observe the number of open stomata on one leaf, mist the leaf with water, wait one hour, and count the number of open stomata again.

D
Austin and Marissa should observe the number of stomata on one leaf, mist the leaf with water, wait one hour, and count the number of stomata that have disappeared.

If one strand of a DNA molecule has the sequence of bases 5′-ATTGCA-3′, the mRNA synthesized following the template will be ____
rjkz [21]

If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.

Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing  template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.

The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.
