In his work with pneumonia-causing bacteria and mice, griffith found that
a. the protein coat from pathogenic cells was able to transform nonpathogenic cells.
b. heat-killed pathogenic cells caused pneumonia.
c. some substance from pathogenic cells was transferred to nonpathogenic cells, making them pathogenic.
d. the polysaccharide coat of bacteria caused pneumonia.

Option (c).

Explanation:

Griffith is known as the father of transforming principle. He worked on the virulent and a virulent bacteria that causes pneumonia. He done his experiment on different heat conditions.

When he heat killed the S strains of bacteria and R strains of bacteria into the mice, the mice was killed. He concluded that there was some substance or transforming principle converts the non pathogenic bacteria into the pathogenic strain.

Thus, the correct answer is option (c).

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

thats not a question
