Answer:
Blood clotting normally occurs when there is damage to a blood vessel.
Explanation:
Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops.
Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.
Please mark me as brainliest :)
Answer:
I think you mean blood clotting so umm
Explanation:
Blood is made up of many different cells—mostly red blood cells, white blood cells and platelets—as well as clotting factors. These and other elements float through blood vessels in a strawlike liquid called plasma.
The coagulation cascade is a complex chemical process that uses as many as 10 different proteins (called blood clotting factors or coagulation factors) that are found in plasma. Put simply, the clotting process changes blood from a liquid to a solid at the site of an injury. Here’s how the process works:
Injury. A cut on the skin or an internal injury creates a small tear in a blood vessel wall, which causes blood flow.
Vessel constriction. To control blood loss, the blood vessel immediately narrows (called constriction), which limits blood flow through the vessel.
Platelet plug. In response to the injury, tiny cells in the blood called platelets are activated. The platelets stick to one another and to the wound site to form a plug. The protein von Willebrand factor (VWF) helps the platelets stick to each other and to the blood vessel wall.
Fibrin clot. Next, blood clotting factors trigger production of fibrin, which is a strong, strandlike substance that surrounds the platelet plug and forms a fibrin clot, a meshlike net that keeps the plug firm and stable. Over the next several days to weeks, the clot strengthens and then dissolves as the wounded blood vessel wall heals.

What is rock formation?A rock formation is a solitary, picturesque, or outstanding outcrop of surface rock. Weathering and erosion shape the existing rock, resulting in rock formations. In stratigraphic and petrologic investigations, the phrase rock formation can also refer to specific sedimentary layers or other rock units.
Energy can be involved in the production of various rock types in a variety of ways. One option is metamorphism, which occurs when rock is exposed to high temperatures and pressures, leading it to alter in composition and structure.

Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.Energy from different sources leads to different types of rock.

Dr. Wong was conducting a field study in the Amazon rainforest when he discovered a prokaryotic organism that has a cell wall and circular chromosomes. Which of the following would he most likely conclude about his discovery
Answer:
it is the plant cells that circle the chromosomes
A prokaryotic organism with a cell wall and a circular chromosome belongs to the kingdom Protista as plants and fungi do not have a circular DNA. Thus, the correct option is B.
What are Prokaryotic organisms?
A prokaryotic organism contains a prokaryotic cell. these cells does not possess a well-defined nucleus and other membrane-bound organelles such as mitochondria, chloroplast, etc. These cells are the most-primitive cells. Due to absence of important cell organelles, these cells cannot survive on their own and hence depend upon other organisms for their nutrition.
Prokaryotic cells have a circular DNA as the genetic material of the cell which is not enclosed in a nucleus instead present in the form of a nucleoid. Prokaryotes such as algae show presence of a cell wall and a circular chromosome inside the cell.
Therefore, the correct option is B.

Principle that involves an attempt to understand the meanings individuals attach to their actions.
Verstehen is the principle which involves the attempt for the understanding of the meanings individuals attach to their actions.
Principle that involves an attempt to understand the meanings individuals attach to their actions.?This idea is based on the German philosophical notion of Verstehen, which also serves as the foundation of sociology as a field of study of people and their behaviour.
The word itself exhibits the quality of deeply understanding something, which makes the method appropriate for sociologists and turns it into a means of learning about people and the acts that they take.
Weber suggested doing this, when one tries to put themselves in other people's shoes and see things from their perspective. The concept and practise of verstehen is today recognised as being essential to rejecting positivist social science (although Weber appeared to think that the two could be united). Understanding the purpose of an action is referred to as verstehen.

The DNA extracted from human cells is used for a variety of purposes, including studying gene function, gene therapy processes, genetic diseases, and developing treatments for them.
What is the purpose of the DNA?The DNA that is present in eukaryotes has plenty of function, but it can't be directly used for study of all these processes. The DNA has both introns and exon sequences in the gene, so first the introns are removed and the gene study is made.
The DNA can be used for genetic studies, to understand the genetic link between different individuals, to study the SNP, etc. The gene in the DNA can be used for recombinant DNA technology, gene therapy, and many other functions, and human DNA can be used to study mutation and its function.

Diploids formed by mating a mutant to a ____ that can grow at ____ temperatures identify the mutation as____ . Only ___ mutations can be studied using complementation analysis. Diploids formed by mating two ___ mutants identify mutations in the same gene if the diploid cannot grow at ___temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at____ temperature (complementation).
Answer:
Each mutant would be mated to wild type and to every other mutant to create diploid strains. The diploids would be assayed for growth at permissive and restrictive temperature. Diploids formed by mating a mutant to a wild type that can grow at restrictive temperatures identify the mutation as recessive. Only recessive mutations can be studied using complementation analysis. Diploids formed by mating two recessive mutants identify mutations in the same gene if the diploid cannot grow at restrictive temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at restrictive temperature (complementation).
Explanation:
Recessive mutations are those whose phenotypic effects are only visible in homo-zygous individuals. Moreover, a complementation test is a genetic technique used to determine if two different mutations associated with a phenotype colocalize in the same locus (i.e., they are alleles of the same gene) or affect two different loci. In diploid (2n) organisms, this test is performed by crossing two homo-zygous recessive mutants and then observing whether offspring have the wild-type phenotype. When two different recessive mutations localize in different loci, they can be considered as 'complementary' since the heterozygote condition may rescue the function lost in homo-zygous recessive mutants. In consequence, when two recessive mutations are combined in the same genetic background (i.e., in the same individual) and they produce the same phenotype, it is possible to determine that both mutations are alleles of the same gene/locus.
