Explanation:
Cancer cells do not contain the capacity to undergo
- a regular cell cycle where they only undergo cell division in response to external signals within their environment, i.e. regulation.
- differentiation into specialized cell types, with different physical traits; together they can't form different tissues.
Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer.
Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.
Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

The word biology mean the so study of:

"the study of the earth and the living organisms "
Answer:
53°.
Explanation:
Rhese method can be used to identigy the orbital projectioons of the organism. The median sagittal plane are specified at the particular angles to obtained the projections.
IR in parieto-orbital projection and median sagittal plane by the rhese method forms the angle of 53° in the projections. These projections are important for the medical diagnosis of individual.
Thus, the correct answer is option (C).
D. The daily release of hot water into the pond from a local factory.
Explanation:
The daily release of hot water into the pond from a local factory would most likely affect the health of fish in a local pond.
Fishes are cold blooded animals. They derive their temperature from the water around them. They need a fairly stable daily temperature.
If the temperature of the water varies to a large extent too much daily, they will suffer.
Hot water will affect the fish population badly. It will cause the fishes to die off and suffer from too much increase in temperature.
Other factors listed in the options will improve the fish life.
