Do jellyfish have eyes
Answer:
it depends on the type of jellyfish.

The instructions, or 'code', in our DNA is dependent upon the order of the _____ in the DNA
-phosphates
-proteins
-bases
- sugars
Answer:
C. Bases
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".
However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.

A. range = 5, median = 9
B. range = 5, median = 14
C. range = 15, median = 9
D. range = 15, median = 14
Answer:
c
Explanation:
The answer is c
Range and median of this data set 16, 10, 24, 12, 9, 14, 11, 14, 21When a list of numbers is arranged from smallest to largest, the median is the middle number, hence option C is correct.
What are the range and median?
The median of these outcomes. The range, in this case, is, where the range is the difference between the lowest and highest values.
Take the sum of all the numbers and divide it by the total number of numbers in the list to get the value of the mean.
Calculate the mean by adding up the center values and dividing them by two in order to determine the median.
Therefore, 16, 10, 24, 12, 9, 14, 11, 14, and 21 in the data set range are equal to the highest number minus the lowest value, hence option C is correct.

What is a phenotype?
Measurement of overall change in position.
Answer:
Velocity (Rate of change of position)Velocity is a vector quantity that is defined as the rate of change of position of an object with respect to a frame of reference with respect to time. Velocity is equivalent to the speed of the object along with the direction of motion.Hope this is fine for youAnswer:Displacement
Explanation:Displacement is the change in position of an object. The SI unit for displacement is the meter. Displacement has direction as well as magnitude. Distance traveled is the total length of the path traveled between two positions.

Explain how diffusion restored homeostasis during the dialysis treatment.
Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answer:
Explanation:
By maintaining amount of ions in the blood.
Countercurrent flow met the goals due to difference in concentration gradient.
Explanation:
Diffusion restored homeostasis during the dialysis treatment because during dialysis, the concentration of ion in the blood is maintained that leads to homeostasis.
Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood
