Answer: Anaphase.
Explanation:
The stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.
Mitosis is a type of cell division by which a parental cell divides in order to produce two genetically identical daughter cells.Mitosis has four phases prophase, metaphase, anaphase, and telophase.During prophase, chromatin condenses into chromosomes, the nuclear envelope disintegrates and spindle microtubules grow and extend from each pole of the cell.During metaphase, homologous chromosomes line up at the equator plate of the cell, the mitotic spindle is fully developed and it attaches to the kinetochores that appear at the centromeres.During anaphase, chromosomes are separated by the elongation of the mitotic spindle and pulled to opposite poles of the cell.In conclusion, the stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.

is adding sodium to water endothermic or exothermic
Answer:
exothermic
Explanation:
Answer:
It takes just slightly more energy to separate the ions from one another than is released from the water molecules surrounding the ions. This means just slightly more energy must be put into the solution than is released back into the solution; therefore dissolving table salt in water is endothermic.

Which statement explains something that the fossil record indicates? Earth is 4.5 billion years old. Mammals have always existed on Earth. Mass extinctions have occurred several times on Earth. The amount of water on Earth has decreased over time.
Answer:
C.) Mass extinctions have occurred several times on Earth.
Explanation:
I Just Took The Fossil Quiz On Edge
The statements that have been indicated from the fossil record are statement 1, 2, 4, and 5 i.e., Earth is 4.5 billion years old. Mass extinctions have occurred several times on Earth. The amount of water on Earth has decreased over time.
What are fossil records?The remnants or indentations of organisms from prior geologic time retained in sedimentary rock constitute the fossil record.
The fossil record is insufficient. Only a low percentage of the life forms preserved as fossils have been managed to recover and studied by paleontologists. In some cases, the evolution of aspects over time has been meticulously renovated. The evolution of the horse is one example.
The following statements have been derived from the fossil record: The Earth has been around for 4.5 billion years. On Earth, mass extinctions have occurred several times. Over time, the amount of water on Earth has decreased.
Thus, the correct options are 1, 2, 4, and 5.

What does the liver do? Please describe almost everything since I'd love to understand the liver completely!
Answer:
the liver processes the blood and breaks down balances and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic more than 500 vital functions have been identified with the liver
Answer:
1. Bili production
2. Protein and cholesterol production
3. Regulates aminoácids in the blood
4. Iron processing in hemoglobin
5. Toxin processing
UreaPoisonsMedicine residue6. Vitamin and protein storage
Explanation:
Think of the liver as a form of "customs" for the body. The liver processes and regulates what enters the blood stream, as well as getting rid of harmful toxins that could damage the body. An example of this would be processing dead blood cells. These cells contain a substance called bilirubin, which breaks down the "heme" in the blood cells once they die/are damaged. Should there be a problem with the liver, the bilirubin can build up and cause a condition called jaundice. This is harmful as if damages elastin-rich tissue.
However, if the liver functions properly, it produces bile through which bilirubin can be disposed of. The liver produces a bile that is stored in the gallbladder, which then can be ejected into the duodenum (intestine) to liquified food. This is essential to help with the digestion and absorption of nutrients.
The liver plays a huge role in metabolism. It synthesizes proteins as well as amino acids. Some of the proteins sythnesized are used for blood clotting factors. It also does lipid metabolism, where it produces cholesterol.
Any build up of toxins in the body goes through the liver in order to be excreted. This excretion is done through bile of through urine. The name "urea" is produced in the blood-stream, and can be fatal if not treated. Fortunately, the liver does the job as it extracts it from the bloodstream and ejects it.
Finally, the liver builds up "fat" as it processes lipids and glucose. Should there not be enough glucose, the liver breaks down its glycogen storage to act as an "emergency reserve", thus providing energy to the body.
Check out John Hopkins Medicine website if you want to learn about the liver more in-depth. It's a very complex organ, and there are whole careers based off of studying it alone.

(5 Points) [Control]Commensal [Control]Mutualistic [Control]Predator-prey [Control]Parasit
Answer:
Commensal
Explanation:
Hope this helps
The type of interaction between the parrotfish and rabbitfish in coral reefs is Commensal.
What is Species interaction?The population of one species interacts with the population of other species that live in the same locality is called species interactions.
Here, in this scenario parrotfish are grazing with rabbitfish in order to escape from predation. As rabbitfish have venomous spines at the end of their pelvic pins and protect the organisms of parrotfish from predators. In this interaction, parrotfish get the benefit to escape from predators and survive freely, while rabbit fish doesn't benefit from this interaction, this interaction is called Commensalism.
Therefore, the type of interaction between the parrotfish and rabbitfish in coral reefs is Commensal.

Which process plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus?
photosynthesis
transpiration
decomposition
respiration
Answer:
C) Decomposition
Explanation: I took the test on edginuty :)
Decomposition plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus. The correct answer is c) decomposition.
What is decomposition?Decomposition is the process by which microbes break down complex organic materials into less complicated ones.
Decomposers, which include bacteria, fungi, and a few other microorganisms, are those who start the decomposition process. To stay alive, they consume dead organisms.
Dead and decaying animals and plants are used as the raw materials for the breakdown process that results in the production of nutrients, carbon dioxide, water, and other things. Raw elements like dead plants, animals, and their remains are referred to as detritus. Once this debris has been processed by microbes, they are referred to as saprophytes.
The creatures that decompose rotting organisms are called decomposers. They return nitrogen and carbon to the environment throughout the decomposition process. They contribute significantly to the ecology by recycling nutrients.
Phosphorus, nitrogen, and carbon are reabsorbed into the ground when an animal or plant decays and is returned, which is necessary for plant growth in the production of food and energy.
Hence, the correct answer is c).

Why are there differences between cell types?
Answer:
There are many different types of cells. For example, in you there are blood cells and skin cells and bone cells and even bacteria. Here we have drawings of bacteria and animal cells. Can you tell which depicts various types of bacteria? However, all cells - whether from bacteria, human, or any other organism - will be one of two general types: prokaryotic or eukaryotic. In fact, all cells other than bacteria will be one type, and bacterial cells will be the other. And it all depends on how the cell stores its DNA.
