Answer:
Answer:
The pH scale has been drawn below.
Explanation:
pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.
Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.
Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:
Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.
Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.
Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.
So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).

b. Energy
c. Mass
d. Volume
Correct answer is C.) mass. Just took the quiz
B) The species has 16 sets of chromosomes per cell.
C) Each cell has eight homologous pairs.
D) During the S phase of the cell cycle there will be 32 separate chromosomes.
E) A gamete from this species has four chromosomes.
For a species with a chromosome number of 2n=16, each cell has eight pairs of homologous chromosomes. There are not 32 chromosomes, 16 sets, or four chromosomes in a gamete.
In biology, the chromosome number 2n=16 indicates that the organism is diploid and has 16 total chromosomes, which are organized into 8 homologous pairs. So, the correct answer is option C) Each cell has eight homologous pairs. The number 16 (2n) represents the total number of chromosomes, not how many sets there are, making option B incorrect. One should not interpret this to mean there are 32 chromosomes in total, so option A is also incorrect. During S phase of the cell cycle DNA replication happens, but this doesn't change the number of chromosomes, just the number of DNA molecules, therefore, option D isn't right. Lastly, a gamete (sex cell) from this species would have n=8, or half the number of chromosomes, contradicting option E.

True of false
I'm choosing false.
neural communication
B.
neurotransmitter release
C.
hormone release
D.
nervous system functioning
Ans.
The image below represents neural transduction that involves release of signaling molecules or neurotransmitters by axon terminal of one nerve cell and binding of the released neurotransmitters with the receptors, present on dendrites of another nerve cell. It is method of communication between the neurons. Hence, the image is showing a functional nervous system.
On the other hands, hormones are released by endocrine glands that release their content directly into the blood. The nervous transmission does not include hormone release.
Thus, the correct answer is option C). 'hormone release.'
