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 correct answer is b. Head movement → Inner ear receptors → Vestibular nerve → Cerebellum.
The balance and equilibrium of the body is maintained by inner ear in the human beings. The parts of internal ear which takes part in balancing and equilibrium are the semi-circular canals and the vestibule. On the movement of head, the otoliths are pull in the direction of gravity.
As prey increase predatory increase and as prey decrease due to the increase of predators. The number of predators will decrease due to the lack of foods.
Answer:
d. Atrophy of the flexor digiti minimi.
Explanation:
The logical diangosis would be d. Atrophy of the flexor digiti minimi.
Flexor digiti minimi is a hypothenar muscle of that is used when we flex our little toe of the foot.Present at the metacarpophalangeal joint. When the foot is in anatomical position, it is lateral to the abductor digiti minimi. it is homologous to digiti minimi in the hands.
Hence, Atrophy of the flexor digiti minimi is necessary.
For the answer to the question above, I believe the answer is
intravenous pyelogram (IVP)It is <span>an x-ray examination that uses injection of contrast material to evaluate your kidneys, ureters, and bladder and to help diagnose the blood in the urine or pain in your side or lower back.</span>
