Which of the following is NOT a property of water?
it requires heat to evaporate
it undergoes rapid temperature changes
it is an excellent solvent
it is a great mixing medium, forming solutions, suspensions and colloids
The Correct Answer is B
A. it requires heat to evaporate: Water has a high heat of vaporization, meaning it requires a lot of energy to evaporate.
B. it undergoes rapid temperature changes: Water has a high specific heat, meaning it resists rapid temperature changes, which helps maintain homeostasis.
C. it is an excellent solvent: Water is called the "universal solvent" due to its polarity, which dissolves many substances.
D. it is a great mixing medium, forming solutions, suspensions and colloids: Water forms various types of mixtures, including solutions, suspensions, and colloids.

Correct Answer is A
Explanation
A. Midsagittal: A midsagittal plane divides the body equally into right and left halves down the midline.
B. Frontal: A frontal (coronal) plane divides the body into anterior (front) and posterior (back) parts.
C. Parasagittal: A parasagittal plane divides the body into unequal right and left portions-not straight down the midline.
D. Transverse: A transverse plane divides the body into upper (superior) and lower (inferior) portions-not left and right.
Correct Answer is A
Explanation
A. nucleus; in the cytoplasm at the ribosomes
Transcription is the process of converting DNA to mRNA and occurs in the nucleus. Translation is the process of reading mRNA to synthesize proteins and occurs at the ribosomes, which are located in the cytoplasm (either free-floating or bound to rough ER).
B. nucleus; in the cytoplasm at the Golgi apparatus
Transcription occurs in the nucleus. But translation does not occur at the Golgi apparatus. The Golgi modifies, packages, and ships proteins, but does not synthesize them.
C. in the cytoplasm at the ribosomes; in the nucleus
This reverses the correct locations. Transcription is not in the cytoplasm, and translation is not in the nucleus.
D. in the cytoplasm at the ribosomes; in the rough endoplasmic reticulum
Transcription does not occur in the cytoplasm. While translation can occur on ribosomes attached to the rough ER, that’s a subset of ribosomes. The general location of translation is in the cytoplasm.
