Although a number of risk factors have been discovered, the exact origins of type 1 diabetes are unknown. A number of HLA-DQA1, HLA-DQB1, and HLA-DRB1 gene polymorphisms enhance the risk of type 1 diabetes.
What hereditary factors contribute to diabetes?Monogenic diabetes is brought on by alterations, or mutations, in just one gene. The majority of the time, these alterations are passed down through families, but occasionally a gene mutation occurs randomly. By reducing the pancreas' capacity to produce insulin, the majority of these gene abnormalities lead to diabetes.

Option B, Increased levels of hormones during puberty can cause an exaggerated response to plaque biofilm.
The hormones during puberty can cause an exaggerated response to plaque biofilm without scientific evidence. It is important to note that oral hygiene and oral health are complex subjects and the effects of hormones on oral health are not well studied.
It would be best to consult with a dentist or a medical professional for more information.
Plaque biofilm is a complex bacterial ecosystem that forms on the surfaces of teeth and gums, and it is known that it plays a major role in the development of tooth decay and gum disease.

!!!!!HURRY PLEASE!!!!!How does the theory of plate tectonics explain the movement of Earth’s plates? Explain In 2 or more sentences.
The theory of plate tectonics states that the Earth's surface is made up of several large, moving plates. These plates are constantly moving, colliding, and pulling apart due to forces generated by the movement of material in the Earth's mantle. The movement of these plates causes the creation of earthquakes, volcanoes, and mountain ranges as well as the formation of oceanic crust and the reshaping of continents over time. The movement of the plate is caused by the convection currents in the Earth's mantle, which causes the plate to move in a slow and steady way.
Independent assortment and genetic variation
Consider a diploid cell where 2n = 6. During metaphase I of meiosis, as the pairs of homologous chromosomes line up on the metaphase plate, each pair may orient with its maternal or paternal homolog closer to a given pole. There are four equally probable arrangements of the homologous pairs at metaphase I. (Note that this problem assumes that no crossing over has occurred.)
The cells below show the eight possible combinations of chromosomes that the daughter cells of meiosis II can receive.
Sort each daughter cell into the appropriate bin depending on which arrangement at metaphase I would create it.
The first daughter cell can receive either the maternal chromosomes or the paternal chromosomes, and the second daughter cell can receive the other set.
During metaphase, I of meiosis, the homologous pairs of chromosomes line up on the metaphase plate. Depending on which homolog is closer to the pole, there are four arrangements of the homologous pairs.
During anaphase I, the homologous pairs separate and go their own way to the opposite poles. As a result, each daughter cell receives a combination of either the maternal chromosomes or the paternal chromosomes.
This arrangement is called the independent assortment and it results in genetic variation among the daughter cells. If a single homolog is passed to each daughter cell, the genetic variation would be reduced. Therefore, the independent assortment is important in creating genetic variation in the daughter cells.

the iris if the eye can have many colors, including brown, blue, green and hazel. how do you think polygenic inheritance explain why many iris colors are possible
The iris of the human eye can have many colors because this trait is controlled by polygenic inheritance. Polygenic traits are phenotypic traits controlled by two or more genes that have a subtle effect on trait variation.
Eye color follows a polygenic pattern of inheritance. Humans recognize nine eye colors. Expression of the eye color phenotype is controlled by two major genes and 14 additional genes associated with the X chromosome. Different combinations of these alleles produce different eye colors. Eye color is directly related to the amount of melanin in the anterior layer of the iris. Brown-eyed people have a lot of melanin in their irises, while blue-eyed people have much less of this pigment.

Is natural selection a stabilizing factor?
Answer:
Stabilizing selection in evolution is a type of natural selection that favors the average individuals in a population.
You overhear a group of people talking about how they support the cloning of endangered species. they believe that the genome of these cloned populations will never change, no matter how many generations of offspring they produce. do you agree with this? explain your answer with reasons.
It is false that the genome of the endangered species will not change upon cloning for several generation. This is because mutations can occur at any stage of the cloning and hence will result in genome change.
Cloning is the process of synthesizing a genetically identical copy of the genome of an organism. This process can occur naturally as well as be done artificially. Naturally cloning can occur by the process of asexual reproduction.
Mutations are the changes in the genetic sequence of a living organism. It can result in the change of the characteristics of the organism due to the change in the protein that is formed from the gene. Some mutations do not cause any change in the protein synthesized and are thus known as silent mutations.

plasma accounts for about ________ percent of the total volume of whole blood.
Plasma accounts for about 55 percent of the total volume of whole blood.
Plasma constitutes 55% of total blood volume. Composed of 90% water, salts, lipids, and hormones, it is especially rich in proteins (including its main protein albumin), immunoglobulins, clotting factors, and fibrinogen.
Plasma performs several functions: transporting blood cells and nutrients; regulating the body’s water and mineral salts; irrigating tissues; providing a defense against infections; and coagulating blood.
The albumin contained in plasma prevents the blood from losing too much water and consistency as it travels through the narrow, water-permeable blood vessels (capillaries). Albumin transports various blood components and nutrients. The immunoglobulins also contained in plasma are antibodies that, along with white blood cells, play an important role in fighting against pathogens.

which type of rna is transcribed from dna to carry a message?
Answer:
Explanation:
RNA is transcribed from DNA to transmit a message. RNA is a nucleic acid that is used to transmit the information contained in DNA genes through protein synthesis. The transcription process is the first stage of gene expression. During transcription, an RNA polymerase molecule binds to a DNA molecule and copies the sequence of nucleotides from a specific gene to produce a complementary RNA molecule.
There are three types of RNA that are produced from DNA transcription: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). mRNA is the type of RNA that is used to transmit genetic information through protein synthesis. rRNA is the type of RNA that is used in protein synthesis, and tRNA is the type of RNA that is used to transport amino acids to the site of protein synthesis.

In the G2 phase, the cell performs a final growth and checks for DNA damage before initiating meiosis.
