Answer: D- Dicer
Explanation:
Dicer, also known as endoribonuclease Dicer or helicase with RNase motif, is an enzyme that in humans is encoded by the DICER1 gene. Being part of the RNase III family, Dicer cleaves double-stranded RNA (dsRNA) and pre-microRNA (pre-miRNA) into short double-stranded RNA fragments called small interfering RNA and microRNA, respectively. These fragments are approximately 20-25 base pairs long with a two-base overhang on the 5' ends. Dicer facilitates the activation of the RNA-induced silencing complex (RISC), which is essential for RNA interference. RISC has a catalytic component Argonaute, which is an endonuclease capable of degrading messenger RNA (mRNA).
Unicellular means One cell, none of the answers are unicellular though.....
Answer:
Types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Active transport requires energy from the cell. Cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

Answer:
This question is incomplete; the complete question is:
Beatrice, a middle school student, is visiting a very tall office building and notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is travelling down. After making these observations, Beatrice comes back to the building and stands on a bathroom scale that measures her weight as she travels up and down in the elevator. What is one variable Beatrice could change in her investigation? What might she figure out if this variable were changed?
ANSWERS:
- Beatrice could change the independent variable, which is the direction of the elevator's movement
- Beatrice might figure out how her WEIGHT responds if she changes the direction of the elevator's movement
Explanation:
According to this experiment, Beatrice notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is travelling down. She decides to test this observation by conducting an experiment where she measures her weight as she travels up and down in the elevator.
In any scientific experiment, the variable that an experimenter can change is called the INDEPENDENT VARIABLE, which in this case is the DIRECTION OF THE ELEVATOR. Beatrice could change whether the elevator will go down or up.
Also, another variable called the DEPENDENT VARIABLE is the variable that responds to the changes made to the independent variable in an experiment. In this case, if Beatrice changes the direction of the elevator's movement, she might figure out her WEIGHT RESPONSE to the direction of elevator movement.
Span of control is accomplished by organ.
