Answer:
Cancer is a chronic disease in which cells reproduce abnormally, exceeding the capacity of the body tissues to assimilate such reproduction, which causes alterations in these cells and in the organs they affect.
Therefore, if a sample is required to determine some type of genetic disorder in the patient, non-cancerous cells should be used, since these will contain genetic material free of any alteration caused by said disease and, therefore, will be a test of greater accuracy to determine said disorder.
It is very essential then to look the genetic makeup to normal cells and compare them to see as it could help in choosing personalized therapy for Lee.
Cancer cell's genes are very unstable in nature and they replicate very fast speed. The use of non cancerous cells will better tell if the cancer is genetic or not when compared to the use of biopsy tissue.
Germline testing is often carried out to know if an individual has a gene mutation that can increase the risk of developing cancers.

An organism with a dominant allele for a particular form of a trait only exhibits the trait sometimes. Please select the best answer from the choices provided T F
Answer:
False. An organism with a dominant allele for a particular form of a trait always exhibits that trait.
Explanation:
According to Mendelian genetics, a dominant allele for a given characteristic will always be expressed in the phenotype, regardless of whether its allelic formula is with both dominant alleles or heterozygous.
In the heterozygous form, the dominant allele is able to avoid the expression of the recessive allele, expressing the phenotype. The recessive allele will only be visible in the genotype when both alleles in the pair are recessive.
In non-Mendelian inheritance, however, there are cases where the dominant allele is expressed in conjunction with another allele, such as co-dominance. In intermediate inheritance different alleles —dominant and recessive— are combined and expressed as a combined characteristic.
Which are characteristics of all living things? Select three options.
grow and develop
make their own food

Answer:
Grow and develop, respond to stimuli, and can reproduce
Explanation: The other random humans are wrong and I just did it on edge 2020
Answer:
The characteristics shared by all living things are that grow and develop, respond to stimuli and can reproduce.
Explanation:
Living things are different, and despite this, they have characteristics in common, since all are able to grow and develop, respond to external stimuli, and can reproduce themselves.
Growth and development: it is a process that occurs in stages and depends on the evolution of the form and functions of the organism.Response to stimuli: it is a function that is called relationship, through which an organism is able to perceive the stimuli of its environment and respond to them.Reproduction: this is the function in which other living beings with the same morphological and functional characteristics can be obtained from a living being.Making their own food and being made of many cells are characteristics that are not shared by all living things, since they correspond to autotrophic organisms and pluricellular organisms only, respectively.

TRANSCRIPTION:
Transcription is the first stage of gene expression which involves the synthesis of mRNA molecule from a DNA template. The double-stranded DNA molecule is separated and each single strand serves as a template for synthesizing a complementary mRNA strand. Adenine pairs Thymine while Guanine pairs with Cytosine in the DNA molecule but in the mRNA strand, uracil instead of thymine is paired with adenine. Therefore, in the process of transcription, the mRNA strand is complementary to the DNA strand; however, uracil instead of thymine is paired with adenine.Learn more at: https://brainly.com/question/9339389?referrer=searchResults

When animals feed off of land faster than the plants can regrow, the land is _______.
a.
below its carrying capacity
b.
forested
c.
overgrazed
d.
depleted
Answer:
C. Overgrazed
This is because there were too many animals on the land to feed, when there are to many animals grazing the same piece of land, it is called overgrazing.
Explanation:
When animals feed off the land faster than the plants can regrow, the land is called "overgrazed." Overgrazing is harmful for an ecosystem. It is caused by cows, goats, etc.
What is overgrazing?Grass is consumed by animals such as cows and goats. Due to overgrazing, the ecosystem is harmed. Due to overgrazing, the plantation of an area is affected. The plants cannot regrow early because they have been fed by animals. Due to the low plantation, it affects the ecosystem's rainfall.
Less transpiration by plants is the result of less rainfall. Hence, less precipitation is seen. The overgrazing causes soil erosion. Generally, soil is held by the roots of the plants. As plants are not there, soil can be easily erased by floods and other natural calamities. The soil erosion caused the land to become sterile. The crops won't grow on sterile land. The infiltration capacity of the soil is reduced.
Hence, the correct answer is "overgrazed." Option C is the correct answer.

that one allele is dominant and the other is recessive. (phenotypic ratio
is the ratio that you expect between the different offsprings' phenotypes
- I would not give this definition on the exam)
Answer:
Answer:
The seven characteristics that Mendel evaluated in his pea plants were each expressed as one of two versions, or traits. Mendel deduced from his results that each individual had two discrete copies of the characteristic that are passed individually to offspring. We now call those two copies genes, which are carried on chromosomes. The reason we have two copies of each gene is that we inherit one from each parent. In fact, it is the chromosomes we inherit and the two copies of each gene are located on paired chromosomes. Recall that in meiosis these chromosomes are separated out into haploid gametes. This separation, or segregation, of the homologous chromosomes means also that only one of the copies of the gene gets moved into a gamete. The offspring are formed when that gamete unites with one from another parent and the two copies of each gene (and chromosome) are restored.

what happens to the rate of photosynthesis of a plant if we decreased the light intensity it receives?
Answer:
Required Answer:- A plant cannot photosynthesise very quickly without enough light.Eventhough There is plenty of Carbon dioxide,water and suitable temperature is available.what would happen if homogenisation and pasteurisation steps are omitted during the production of yoghurt
Answer:
The correct answer would be - there could be microorganisms like bacteria present and consistency or texture would be not as expected.
Explanation:
Pasteurization is more of a safety process that helps in the elimination of microorganisms like bacteria and this process involves heating the liquid and cooling it down immediately to a very low temperature.
Homgenisation is the process that makes liquid particles evenly small and distributed equally which gives it consistency or texture and taste. Without these two processes, yogurt will have bacteria and inconsistency.

Explanation:
Examine a two-gene cross that follows simple Mendelian inheritance of freckles and eyebrow shape between a woman with genotype Mmpp and a man with genotype mmpp. How many phenotypes are possible in their offspring and in what ratio?
a. 4 phenotypes: 9:3:3:1
b. 2 phenotypes; 1:1
c. 3 phenotypes; 8:4:4
d. 3 phenotypes; 1:2:1
The number of possible phenotypes in the Mendelian cross would be 2 in the ratio 1:1.
Phenotypic ratiosFirst, let us look at the result of crossing the two genotypes Mmpp and mmpp.
Mmpp will give the gametes Mp, Mp, mp, and mp
mmpp will give the gametes mp, mp, mp, and mp
The two sets of gametes can thus be lined up on both axes of the Punnet's square as shown in the attached image.
Genotypes of the offspring: 8 Mmpp and 8 mmpp
Since the two genes follow a simple Mendelian inheritance pattern, the 2 genotypes automatically equate to 2 phenotypes in the ratio 1:1.
Hence, the correct option is b.

Answer:
C
Explanation:
Father/mother must each donate a blood gene to the child. Father must have a genotype of ii because O blood is recessive. Thus, the kid must have one O type gene. However, the kid has A type blood overall, so the kid must have an A (dominant) gene as well. Thus, the answer is IAi.
