Scientists wanted to learn more about Griffith's experiment. They extracted a mixture of various molecules from the heat-killed bacteria. They found that Choose
no longer occurred when they treated the mixture with enzymes that destroyed Choose..
This experiment
supports the hypothesis that Choose..
is the genetic material

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.

the answer is c. it will give up it's valence electron to the other atom.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

d. planting trees

the trees take in carbon to make oxygen.
