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.
B. the amount of cellular energy would increase
Answer:
Pancreas; islet of langerhans
Explanation:
Insulin and Glucagon are both hormones released into the bloodstream with the function of regulating blood sugar level. Insulin is released when the blood sugar level (glucose) is high, hence, it converts excess glucose to glycogen, which is stored in muscles. Insulin also helps the cell to utilize glucose as an energy source. Glucagon, on the other hand, functions to convert stored glycogen to glucose (glycogenolysis) when the glucose levels in the blood is low.
Both hormones i.e. Insulin and Glucagon are secreted into the bloodstream by an endocrine gland called PANCREAS, which is a digestive organ found near the stomach. Specifically, the pancreas contains regions that contain endocrine cells called ISLET CELLS. This region, called Islet of Langerhans, is where the hormones are produced in the PANCREAS.
D
B makes no sense
C makes so sense as variation causes natural selection so if they were all the same natural selection wouldnt happen
A isnt right
the answer is D as the organisms must have some variation in order to be different enough and less/more well adapted to their habitat in order for the less well adapted ones to die- and the more well adapted ones to live and pass on advantageous alleles/genes
