Answer:
It can reveal the type of diet it had (omnivore, herbavore, or carnivore)
Explanation:
By the placement, sharpness and type of teeth, scientests can tell the diet of the animal.
Answer:
Altruistic behavior, such as sterile worker ants caring for the offspring of their queen, evolves only between related individuals through what is known as kin selection — or so many evolutionary biologists have thought since the 1960s.
Answer: Bribery
Explanation:
Bribery can be defined as the act of giving something of the value in return for some kind of influence or action in return, which the receiver would have not offered without the price value.
Here, in this case also the oil company might have paid some bribe to the government officials in order to get approved their project.
Due to bribe the government officials approved their project without being thinking of the consequences of the project.
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.

Blood is made up of red and white blood cells, platelets and plasma. The plasma consists of water (mostly) and dissolved nutrients. When blood is exposed to air, the blood will clot, due to aggravation of the platelets. Then you get a forming scab that will help heal the part that the blood is being exposed from.
