Answer:
C. Arrow 1 represents interphase, and Arrow 2 represents mitosis.
Explanation:
When we talk about the whole cell cycle we are referring to the interphase and the cell division (mitosis or meiosis).
Interphase: Represented in the cycle by arrow 1.
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage occurs the DNI replication process. At this point, also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
• G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Once the whole interphase is completed, mitosis occurs.
Mitosis: Represented in the cycle by arrow 2.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the cell separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles. Sister chromatids are held together until they reach the Anaphase, during which other enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles. In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, occurs cytokinesis.

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.
Answers
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

B. range = 5, median = 14
C. range = 15, median = 9
D. range = 15, median = 14
Answers
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.

-phosphates
-proteins
-bases
- sugars
Answers
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.
