Answer:
Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships.
Explanation:
Basically it is a hypothesis from before hypothesis actually were called hypothesis
RNA polymerase: An enzyme that is responsible for making rna from a dna template.
Ribosome: a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells.
Promoter: A region of DNA that initiates transcription of a particular gene.
Regulator: Any organism that can maintain a constant internal environment largely independently of the external environment.

The thalamus - serves as the relay center of the brain where most senses are routed for processing.
Answer:
3 UCA 5
Explanation:
The 5' end of a strand pairs up with the 3' of its complimentary strand. So with this fact, we can rule out option C.
Now when you pair the DNA template with the mRNA template, remember that RNA contains uracil and not thymine. So the base pairings would be:
T = A
A = U
U = A
G = C
C = G
Based on this, the pairing would be like this:
5' A G T 3'
3' U C A 5'
The four systems that describe the functions of the circulatory systems are:
- oxygen is delivered to cells throughout the body by this system
- This system removes carbon dioxide from organs & delivers it to the lungs.
- Carbon dioxide exits the body through this systems
- This system's organs pass oxygen into the bloodstream.

What is the circulatory system?
The circulatory system can be referred to as a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of humans or other vertebrates.
The circulatory system includes the cardiovascular system, also known as the vascular system which consists of the heart and blood vessels.
