Answer:
Hydrogen bonding between water molecules allows water to be <u>cohesive.</u> This property of water allows it to rise from a plant's roots to its highest branches.
Explanation:
Cohesion is that force of attraction between molecules that holds the particles of a substance together with others of the same type. It is said that a liquid has more or less cohesion, depending on whether its molecules are more or less attracted to each other. In water, the cohesion force is high because of the hydrogen bonds that hold the water molecules tightly bound together, forming a compact structure. For example, in plants, it is essential that the water column be kept continuous, so that the tension of the xylem (conductive plant tissue) is transmitted to the root. The water column is held together thanks to the powerful cohesion forces that attract water molecules together.
Answer:
Hershey and Chase concluded that DNA, not protein, was the genetic material. They determined that a protective protein coat was formed around the bacteriophage, but that the internal DNA is what conferred its ability to produce progeny inside a bacterium.
Explanation:
Pathogens are microorganisms - such as bacteria and viruses - that cause disease. Bacteria release toxins and viruses damage our cells. White blood cells can ingest and destroy pathogens. They can produce antibodies to destroy pathogens, and antitoxins to neutralize toxins
