Answer:What are the difference between prokaryotic and eukaryotic cells? Eukaryotic cells have membrane-bound organelles with a nucleus, and are large, while prokaryotic cells are small and do not have membrane-bound organelles. eukaryotic cells can also reproduce asexually by mitosis, while prokaryotic cells cannot.
Explanation:hope this helps and happy halloween
Prokaryotic cells do not have a membrane-bounded nucleus, but eukaryotic cells do not have such a nucleus'.
What does not distinguish a prokaryotic cell from a eukaryotic cell?Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
Thus, Prokaryotic cells do not have a membrane-bounded nucleus, but eukaryotic cells do not have such a nucleus'.

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

Clara bought a beautiful plant for her apartment. Clara lives in a basement apartment that receives very little sunlight. She placed the plant close to the only window in the apartment. After a few weeks, the plant has started to die. Clara is very confused and upset. She gave the plant fertilizer and enough water. Explain to Clara why her plant is dying.
Answer:
The plant is not receiving enough sunlight.
Explanation:
Some plants require direct sunlight for a few hours at a time in order to stay healthy. Because Clara lives in a basement apartment that doesn't receive much sunlight, it is an unsafe environment for a plant to live in. Plants need sunlight to create energy, creating that energy also creates food which allows the plant to consume that food and feed itself. If the plant doesn't receive enough sunlight because it is in a place where not much sunlight goes then it cannot create the amount of food, it needs to survive which will cause it to die slowly. If Clara wants to save her plant, she needs to keep giving it proper fertilizer and water while finding a new location to put it where it can receive all the sunlight it needs to create its food.

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.

Cytoplasm dissolve in it the molecules released by organelles present in it. It acts as a reservoir for dissolution of molecules not required instantly by the cell to conduct any metabolic activity except lipids. It can dissolve proteins, glucose etc. Pathways like glycolysis takes place in cytoplasm.
Chloroplasts: It is a cell organelle found in plants. The function of chloroplast is to carry out photosynthesis in plants. It uses pigment which traps the sunlight. It converts the sunlight energy into chemical energy in the form of ATP and NADPH.
Cell wall: It is the semi- permeable layer outside the plant, fungi, algae and bacteria. It's main function is to provide structural support to the cell. It facilitates the import and outport of molecules in and of the cell necessary for cell function.
Centrioles: They are the cell organelles which are visible during the cell division.The centrioles are the sites where the spindle fibers originate. These spindle fibers gets attach with the each membrane of the chromosome pair and facilitate their separation during cell division.

To construct linkage maps, scientists estimate the distance between genes on the same chromosome based on the ______, as indicated by the percentage of recombinant offspring.
To construct linkage maps, scientists estimate the distance between genes on the same chromosome based on the crossover frequency. It is also called recombination.
What is a crossover?Crossover or recombination is the interchange of genetic material between non-sister chromatids during meiosis.
In genetics, this rate of recombination is useful to develop linkage maps (i.e., genetic maps).
These genetic maps are not equal to distance maps, which are constructed based on nucleotide distances.

:)Hope this help you out friend:)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.

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.

Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
a.) from the ground
b.) from the air
c.) from the water
d.) from the sun
Answer:
b.) from the air
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
