During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes
Answer:
The correct answer is - cell must make a copy of every chromosome.
Explanation:
Mitosis is the cell cycle where cells form two identical daughter cells. It is essential to the daughter cells have a copy of every chromosome, and therefore, It copying the chromosomes during mitosis and separating the chromosome copies to provide a new cell with a complete set of chromosomes.
In the Interphase phase, the DNA breaks up evenly so that each new daughter cell has the same amount of DNA that helps in providing a complete set of chromosomes.
During mitosis, the original cell must undergo DNA replication in order to ensure that each of the daughter cells has a complete set of chromosomes.
In mitosis, a type of cell division, a single cell divides to produce two daughter cells. The goal of mitosis is to distribute the replicated chromosomes equally between the daughter cells so that each cell has a complete set of chromosomes. Before the cell enters mitosis, it undergoes a phase called interphase, during which DNA replication occurs. During DNA replication, the genetic material (chromosomes) in the cell is duplicated, resulting in two identical copies of each chromosome. These duplicated chromosomes are known as sister chromatids.
When mitosis begins, the sister chromatids condense and align along the cell's equator during metaphase. Then, during anaphase, the sister chromatids separate and move towards opposite ends of the cell. This ensures that each daughter cell receives one complete set of chromosomes. Finally, during telophase and cytokinesis, the cell divides into two, resulting in the formation of two genetically identical daughter cells, each with a complete set of chromosomes.
In summary, the DNA replication that occurs during interphase is essential for ensuring that each daughter cell produced during mitosis has a complete set of chromosomes. This process allows for the accurate transmission of genetic information from one generation of cells to the next.

Which type of cell division causes a puppy to grow into an adult dog?
meiosis
mitosis
eukaryotic
O homeostasis
Mitosis is the kind of cell division which allows a puppy to develop into an adult dog. So, the correct option is B.
What is Mitosis?In eukaryotic cells, a process called mitosis produces two daughter cells, each of which has the same amount of chromosomes as the parent cell. Multicellular organisms, like dogs, go through a process called mitosis during which cells divide and differentiate into different cell types.
The process of meiosis, on the other hand, produces gametes with half as many chromosomes as the parent cell and is only able to occur in specialised cells, such as the ones involved in sexual reproduction. Contrarily, homeostasis has nothing to do with cell division and instead refers to the preservation of a constant internal environment within an organism.
Therefore, the correct option is B.

would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.
If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.
What is the name of the membrane surrounding the brain? What is the
function of this membrane?
Answer and explanation:
The meninges
There are actually 3 parts—dura mater, arachnoid, and pia mater.
The brain is soft and mushy, and without structural support it would not be able to maintain its normal shape. In fact, a brain taken out of the head and not properly suspended (e.g., in saline solution) can tear simply due to the effects of gravity. While the bone of the skull and spine provide most of the safeguarding and structural support for the central nervous system (CNS), alone it isn't quite enough to fully protect the CNS. The meninges help to anchor the CNS in place to keep, for example, the brain from moving around within the skull. They also contain cerebrospinal fluid (CSF), which acts as a cushion for the brain and provides a solution in which the brain is suspended, allowing it to preserve its shape.
The outermost layer of the meninges is the dura mater, which literally means "hard mother." The dura is thick and tough; one side of it attaches to the skull and the other adheres to the next meningeal layer, the arachnoid mater. The dura provides the brain and spinal cord with an extra protective layer, helps to keep the CNS from being jostled around by fastening it to the skull or vertebral column, and supplies a complex system of veinous drainage through which blood can leave the brain.
The arachnoid gets its name because it has the consistency and appearance of a spider web. It is much less substantial than the dura, and stretches like a cobweb between the dura and pia mater. By connecting the pia to the dura, the arachnoid helps to keep the brain in place in the skull. Between the arachnoid and the pia there is also an area known as the subarachnoid space, which is filled with CSF. The arachnoid serves as an additional barrier to isolate the CNS from the rest of the body, acting in a manner similar to the blood-brain barrier by keeping fluids, toxins, etc. out of the brain.

Does they type of animal (i.e. mammal, reptile, amphibian, bird) determine at which trophic level they exist? Why or why not?
The various species belonging to these groups can belong to various levels of consumers. But, none of them are producers.
What are trophic levels?
Trophic level is a level in an ecosystem's food chain or nutritional chain. Based on their eating habits, organisms in a chain are divided into various stages. The producers, or green plants, are found on the first and lowest level.
The herbivores, or plant eaters, are second-level creatures that eat plants or their products. Primary carnivores, or meat eaters, consume herbivores at the third level, while secondary carnivores consume primary carnivores at the fourth level.
Since many creatures graze on many trophic levels, these classifications are rarely rigidly enforced. For instance, certain omnivores—which are carnivores but sometimes occasionally ingest plant material or animal carcasses—are also herbivores. A further trophic level called the decomposers or transformers is made up of creatures like bacteria and fungi that convert waste products and dead organisms into nutrients that the producers may use.
Therefore, the various species belonging to these groups can belong to various levels of consumers. But, none of them are producers.

A. volume increases and density decreases
Explanation:
I got a 5 on mastery test thanks to some comments on original answer
Based on the graph, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.
What is the density-temperature relationship?The density of a substance is defined as its mass per unit volume. In the case of water, the density varies with temperature, as shown in the graph. At 4°C, the density of water is about 1000 kg/[tex]m^3[/tex]. As the water is cooled, its density decreases, reaching a minimum of about 999.87 kg/[tex]m^3[/tex] at 3.98°C (this is the temperature at which water is most dense). As the water is cooled further, the density increases again, but it remains lower than it was at 4°C. The reason for this behavior can be explained by the way water molecules behave as they are cooled. At higher temperatures, the water molecules have more kinetic energy and are more spread out, resulting in a larger volume and lower density.
Hence, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.
