The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
Answer:
C. Plant --> Mouse --> Snake --> Bird
Explanation:
the mouse would feed from the plant, the snake will then eat the mouse, and the bird will eat the snake (usually if they are big birds not like the one from the picture)
The cell membrane folds upon itself easily, which facilitates cellular reproduction by mitosis.
<span>The membrane is a flexible, fluid mosaic and changes shape easily to create holes for substances to move in and out of the cell. </span>
<span>The outer layer of the membrane is hydrophilic, which allows water to flow in and out of the cell easily to eliminate waste. </span>
<span>The proteins that are embedded in the cell membrane act as channels to transport substances in and out of the cell.</span>
Answer:
Yes. That was the question he was trying to answer.
Explanation:
To conduct the experiment investigating the connection between pillows and disease-causing gems, Dr. Philip needs to ask himself whether the pillows that will be used in the research contain germs that contribute to allergies in a family. This question allows Dr. Philip to have the basis to start his research and come to a conclusion about the pillows used in the research. Furthermore, the research points directly to the main point of the story.
Answer:
A. Submandibular
B. Parotid
Explanation:
The amylase is an enzyme that turns starch into sugars and is presented in the saliva of humans and other mammals. It begins the digestive process. Besides the salivary glands, the pancreas also produces it to help turn starch into sugar and convert that, with other enzymes, in glucose to supply the body with energy.
I hope this answer helps you.
