Cystic fibrosis is a disorder that causes the mucus glands to produce very thick mucus. Problems with the respiratory and digestive systems often occur in individuals with this condition. Like many disorders, cystic fibrosis occurs when there is a simple change, or mutation, in the DNA of a particular gene.

According to the information above, genetic mutations
A.
will always cause death in humans.
B.
can contribute to or cause diseases in humans.
C.
can only cause diseases in plants and wild animals.
D.
usually result in the release of excess mucus.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

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.  

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
