What is a limitation of this diagram? (1 point) It does not show that mitosis creates more than two daughter cells. It does not show all phases of mitosis. It does not show senescence. It does not show the final result of mitosis.
Since the diagram is about cell division and is indicating with an arrow that the cell has gone through the interphase and mitosis events, its limitation is that it does not show all phases of mitosis. Option B.
---------------------------
The diagram is about cell division through the process of mitosis.
It shows a cell, its nucleus, and chromosomes.The arrow indicates that the cell has gone through the S phase and then through mitosis.Finally, it shows the two daughter cells.Let us first review the stages involved in cell division. After that, we will answer the question.
INTERPHASE
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage. During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated. The 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.
MITOSIS
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Mitosis occurs in four stages.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles. In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.CYTOKINESIS
Finally, cytokinesis occurs. It occurs immediately after mitosis, and refers to the cytoplasmic division.
Options:
A) It does not show that mitosis creates more than two daughter cells.This is not correct because a single mitosis event produces only two daughter cells. Succesive mitosis can produce many new cells. But each cell can only divide into two.
B) It does not show all phases of mitosis.This is correct. The diagram only says that mitosis has occurred, but it does not represent all the phases.
C) It does not show senescence.The diagram does not show senescence, but porbably because it is not involved in cell division. So this optionn would not be correct either.
D) It does not show the final result of mitosis.This is wrong because it is showing that there are two new daughter cells, which are equal to the original cell.
So the only correct option is B

Summary of Photorealism
The name Photorealism (also known as Hyperrealism or Superrealism) was coined in reference to those artists whose work depended heavily on photographs, which they often projected onto canvas allowing images to be replicated with precision and accuracy. The exactness was often aided further by the use of an airbrush, which was originally designed to retouch photographs. The movement came about within the same period and context as Conceptual art, Pop art, and Minimalism and expressed a strong interest in realism in art, over that of idealism and abstraction. Among several male practitioners of Photorealism there is an interest in themes of machinery and objects of industry such as trucks, motorcycles, cars, and even gumball machines, whereas Audrey Flack, the sole female practitioner, infuses her works with greater emotionality and the transience of life. Ultimately, the Photorealists were successful in attracting a wide audience, but they are often overlooked by art historians as an important avant-garde style.

Mitochondria used to free living bacteria. They have their own DNA and ribosomes. Millions of years ago mitochondria began living inside of eukaryotic cells providing them with ATP in exchange for a place to live. Today we find mitochondria in every type of eukaryotic cell. Plants, animals, fungus and protist ALL have mitochondria to break down glucose into ATP.
What is the type of relationship between mitochondria and eukaryotic cells?
Answer:
Mitochondria and chloroplasts likely evolved from engulfed bacteria that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic bacterium, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion. (nature.com)

Greg is in a bike race. At mile marker four (out of ten), his speed was measured at 13.5 mph. Which best describes the measured number? It is the average speed of the bike rider. It is the instantaneous speed of the bike rider. It is the instantaneous velocity of the bike rider. It is the average velocity of the bike rider.Which is a valid velocity reading for an object? 45 m/s 45 m/s north 0 m/s south 0 m/s
Answer:
The correct answer is - It is the instantaneous speed of the bike rider.
Explanation:
Velocity is the speed with the direction so, it is a vector while speed is the specific distance covered in a unit of time, as there is no sense of direction it is scalar.
The instantaneous speed is the speed of an object at a particular or specific instant of time, in this case, the speed of the biker is mentioned not the velocity as a direction not given
Thus, the correct answer is option - It is the instantaneous speed of the bike rider.

Why do we compare the dermal tissue of plants to human skin? Explain your answer.
Answer:
They are like each other
Explanation:
Your skin covers your body, protecting it from abrasion, water loss, and infection and secreting conditioning substances. The epidermis of a plant serves similar functions. Usually a single layer of closely-packed cells, epidermal tissue covers leaves and young stems and roots of vascular plants. Most epidermal cells secrete waxy substances which form a cuticle, or waterproof covering, over the aerial surfaces of the plant, such as the stems and leaves. The cuticle also resists viral, bacterial, and fungal invasion.

In this assignment, you will create a poster that models how the circulatory and respiratory systems work
together to ensure homeostasis through gas exchange. The poster should highlight the roles of
components in each system as well as the interaction between the two systems. You will also write two
paragraphs describing the contents of your poster.
Answer:
I hope this helps those who are struggling with it :) I got 100% and please, rewrite in your own words.
Explanation:
To supply the body with oxygen, the respiratory system collaborates directly with the circulatory system. Inhaled oxygen travels into blood vessels where it is subsequently circulated to tissues as well as cells through the body's circulatory system.
What is respiratory systems?In both animals and plants, the respiratory system would be a biological system made up of particular organs and structures that are employed for gas exchange. Based on the size of the organism, its habitat of living, and its evolutionary background, the anatomy or physiology that cause this vary drastically.
What is circulatory system?A human or other vertebrate's complete body is circulated by a system of organs called the blood circulatory system, that includes the heart, blood arteries, and blood itself. It contains the heart and blood vessels-based cardiovascular system, often known as the vascular system.
The nasal cavity, larynx, pharynx, epiglottis, trachea, bronchioles, bronchi, alveoli, as well as lungs are all components of the respiratory system.
The primary function of the respiratory system would be to introduce fresh air entering our body while expelling waste gases. After entering the lungs, oxygen travels through your body's bloodstream. The waste gas carbon dioxide has been exchanged for oxygen in each cell in your body.

During which portion of the cell cycle does the amount of dna in the cell decrease by half?.
Answer:
Through this remaining period, until the conclusion of mitosis, the cell contains 92 chromatids. Only the G1 phase precedes the S phase and has half the amount of DNA as the rest of the cell cycle; therefore, cells in the G1 phase have the least amount of DNA.
In the cell cycle, DNA becomes half at the division phase, or M phase (mitotic phase). As a result, each daughter cell gets a copy of the genetic material of the parent cell.
How does DNA number decrease in cell division?In the S phase, DNA duplicates, and as a result, the DNA number becomes double. In the case of humans, there are a total of 23 pairs of DNA, or 46. In the S phase, the DNA number becomes double, which is 92. The chromosome number remains the same in S phase that is 46. Chromosome numbers are counted by their centromere number. The number of centromeres and chromosomes are same.
In the division phase (M phase), the cell divides and the duplicated chromosomes are separated to make daughter cells. As a result, the 92 DNA of a cell are divided into 46 DNA. Each daughter cell has 46 DNA, or 23 pairs in M phase. In mitosis each daughter cell has 46 DNA, while in meiosis each daughter cell has 23 DNA.
Hence, in M phase and especially in anaphase, the DNA becomes half.
