Answer:
1.B. Yes, water is able to pass across the membrane through the aquaporins
2.A. Neither NaCl nor water can move across the cell membranes.
Answer:
C
Explanation:
A)
DNA directs the synthesis of RNA.
B)
DNA splits into two strands of RNA.
C)
A strand of DNA is used as a template for the formation of RNA.
D)
Two strands of RNA are formed by copying each of the strands of DNA.
The correct answer would be that <u>a strand of DNA is used as a template for the formation of RNA.</u>
<em>Transcription is a process during which RNA is synthesized using DNA as a template. The coding strand of the DNA is utilized as a template for the formation of messenger RNA. During this process, the double helix structure of the DNA is unwound by an enzyme and the coding strand is bound by a short DNA strand at the beginning of a gene while another enzyme adds RNA nucleotide bases to elongate the short strand.</em>
The correct option is C.
Answer: B. Water molecules slow down until they begin to bond together.
Explanation: When water is cooled, energy is removed from the system, and the molecules begin to slow down. When the molecules have slowed suciently, their collisions are no longer energetic enough to overcome their electrostatic attraction, and they begin to bond together. The other answer choices are inaccurate. Since ice is less dense than water, high pressure compresses the ice and actually causes it to melt. (Compression has no effect on water volume.) Cooling has no effect on the shape of individual water molecules.
Molecular Biology
This field of study deals with everything related to macromolecules, thus, what you will need for molecular biology would be something you could get proteins and nucleic acids from. Among the choices, the DNA of a pig and a calf would be the most helpful.
Comparative Anatomy
Comparative anatomy is a field of study that focuses on any similarities or differences between the anatomy or structure of different animals or species in general. Among the options, having the limb structure of a pig and a calf would allow you to practice the field since you have a structure to compare.
Developmental Biology
In this field, your concern would be how species grow and develop. For you to properly observe the growth and development, you must have the embryo of a pig and a calf. Therefore, among the options, this is the correct piece of evidence for this field.
IN SUMMARY:
Molecular Biology - Both DNA of a pig and a calf
Comparative Anatomy - Both limb structure of a pig and a calf
Developmental Biology - Embryo of a pig and a calf
This patient has has a medial epicondylar fracture of the humerus (part of the humerus that forms the elbow joint medially). The patient was treated surgically by either open or closed reduction of the elbow. In coding this particular disease, the most appropriate code to use is CPT 24565-54-RT and 24605-54-51-RT that encompasses "<span>Fracture and/or Dislocation Procedures on the Humerus (Upper Arm) and Elbow".
