Which change forms a new substance?
The change were new material is produce is called chemical change.
What kind of material is chrysotile?
Chrysotile is a form of asbestos accounting for about 95 percent found in the United States. It is a soft, fibrous silicate material. Chrysotile and other forms of asbestos are considered to be hazardous.
What is biochemical comparison?
Biochemical comparisons are limited to comparing two living life forms. Before the comparison can be made, you have to study the genetic relationship between the two living things.
What is pHEMA?
pHEMA is an abbreviation of the polymer poly(2-hydroxyethyl methacrylate). This material forms hydrogen in water and was first used in optical implant.
What are two types of genetic drift?
Founder effect- isolation of few individuals from larger population; new population forms with different gene pool. Bottleneck effect- Drastic reduction of population size leading to a restrictive gene pool in wich the population must use to recover. Forms population with different gene pool.
Does the same genetic material have to remain together?
No, the same genetic material does not have to remain together. During processes such as meiosis and recombination, genetic material can be shuffled and exchanged between chromosomes, leading to genetic diversity. Additionally, in asexual reproduction, organisms may pass on genetic material that has undergone mutations or changes, further emphasizing that genetic material can exist separately or in varied forms.
What is the chiasma?
A chiasma is a cross-shaped structure that forms during meiosis when non-sister chromatids exchange genetic material. This process is known as genetic recombination and helps increase genetic diversity in offspring.
What is translocation downs syndrone?
Translocation Down syndrome is a genetic condition caused by the presence of an extra chromosome 21 due to a rearrangement of genetic material between chromosomes. Unlike the more common forms of Down syndrome, which result from an extra full chromosome 21, translocation Down syndrome occurs when a portion of chromosome 21 becomes attached to another chromosome. This can happen during the formation of reproductive cells or in early fetal development. Individuals with translocation Down syndrome typically exhibit the same physical and cognitive characteristics associated with Down syndrome.
Is Parkinson disease on chromosome 6?
No, Parkinson's disease is not caused by a mutation on chromosome 6. The exact cause of Parkinson's disease is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Some rare forms of Parkinson's disease are linked to specific gene mutations, but these are not located on chromosome 6.
Which chromosome does Lou Gehrig s Disease occur on?
Lou Gehrig's Disease, also known as Amyotrophic Lateral Sclerosis (ALS), is primarily associated with mutations in the SOD1 gene, which is located on chromosome 21. However, ALS can also be linked to mutations in several other genes that may be found on different chromosomes, including C9orf72 on chromosome 9 and FUS on chromosome 16. The disease can have both genetic and sporadic forms, with various genetic factors involved.
Job of chromosomes?
Chromosomes contain DNA that carries genetic information essential for traits and functions of an organism. During cell division, chromosomes ensure that genetic material is correctly copied and distributed to offspring cells. Chromosomes play a crucial role in determining characteristics, such as eye color, height, and susceptibility to diseases.
Can the genetic material for both plants and animals is DNA?
All living organisms have DNA. They differ subtly, but are about 99% similar.
What sugar forms an important constituent of the genetic material of a cell?
deoxyribose found in DNA and ribose found in RNA.
What structure forms in pro phase along which the chromosome move?
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
How does the egg or sperm compare to a fertilized embryo?
An egg is a mature female reproductive cell containing half the genetic material necessary for reproduction. A sperm is a male reproductive cell containing half the genetic material necessary for reproduction. A fertilized embryo forms when an egg and sperm unite, combining their genetic material to create a new individual with a full set of genetic information.
What is The genetic material that determines the nature of life forms?
The genetic material that determines the nature of life forms is deoxyribonucleic acid (DNA). DNA contains the instructions for the development, functioning, growth, and reproduction of all known living organisms and many viruses. It is composed of sequences of nucleotides, which encode the information necessary for synthesizing proteins and regulating cellular processes. In some viruses, ribonucleic acid (RNA) serves as the genetic material instead of DNA.
The genetic material of prokaryotes is?
The genetic material of a cell is actually the DNA (DeoxyriboNucleic Acid) molecule. In some types of cells this genetic material is packaged alongwith many other chemicals in the form of long thread-like structures called chromosomes and enclosed in a membrane-lined struture. This spherical structure is called nucleus and such cells are called eukaryotes. In other types of cells the genetic material is not enclosed in a nucleus but rather lies exposed to the cytoplasm of the cell. These are the prokaryotic cells of which bacteria are the prime examples. The cells of most higher forms of life (plants and animals) are eukaryotes.
