Answer:
is the process of water moving through a plant.
Explanation:
The common example of sublimation is shrinking of ice cubes that are not used in the freezer and conversion of dry ice rapidly into wispy clouds which vanish very soon
Answer:
1. Ends of the respiratory branches are called alveoli.
2. C. To control blood flow to different areas of the body depending on activities
Explanation:
1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.
The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.
2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.
This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.
