In appositional growth of cartilage, Select one: a. chondroblasts within the tissue proliferate and add more matrix from the inside. b. new chondrocytes and new matrix are added on the outside of the tissue. c. osteoblasts replace the chondroblasts. d. the tissue becomes vascularized in order to grow. e. the cartilage is replaced with another kind of connective tissue.

individual oxygen atoms are formed during photosynthesis.-c.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
