What is one similarity between the lungs and capillaries? they are both activated by inhalation. they are both involved in gas exchanges. they are both part of the circulatory system. they are both regulated by the heart.

The answer is ‘They are both part of the circulatory system’. The lungs expire carbon dioxide brought in by the blood capillaries in the alveoli (carbon dioxide from tissues) and also incorporates oxygen into the blood in the same capillaries’ blood. This oxygen is taken to the tissues. This phenomenon in the lungs is called gaseous exchange.  The gaseous exchange also happens in the tissues when blood in the capillaries exchange oxygen to tissue for carbon dioxide from tissue.  

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.  

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
