Answer:
When a bullet strikes, a characteristic ‘keyhole’ is formed—a defect that is circular at one end with tangential fractures radiating outwards in parallel, allowing the bone between them to lever out. So, in other words a major surgery is needed to get the bullet out. It is very risky as well
Explanation:
The correct answer is letter C. Dendrites <u>receive information from other neurons or from the external environment.</u> Dendrites are part of the neurons that are responsible for receiving information from the axon and the synapses that occur within the Central and Peripheral Nervous System. These dendrites branch off into multiple other synapses in order for the body to create a long chain of nerve impulses.<u />
Answer:
DNA is also called deoxyribonucleic acid which is made up of two chains which wind around each other to form a double helix model. The 2 DNA strands are also called polynucleotides and they are made up of monomeric units known as nucleotides. These nucleotides are made up of one of four nitrogen-containing nucleobases: cytosine, guanine, adenine and thymine, a phosphate group, and sugar known as deoxyribose.
Nitrogen bases present on the two separate polynucleotides strands are bound together with the help of base pairing (such as adenine with Thymine) and with hydrogen bonds to form double-stranded DNA.
So, adenine in DNA is complementary to thymine.
