body temperature and hormone levels. give two examples from the reading of how living things respond to changes in their environment. sweating on a hot day and squinting at the sunlight. ... reproduction, based on genetic code (DNA), grow and develop, obtain and use materials and energy, respond to environment, organized.
The amount of water that condensed at the top of the terrarium change as plants sprouted and grew because water, oxygen and nutrients are very essential elements for growth.
The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities. Nutrients (macro and micro essential elements) are required by plants for the synthesis of protoplasm and act as source of energy.
Thus as plant grows it needs more water to provide to it's larger plant body and which causes decrease in the amount of water that condensed at the top of the terrarium.

A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
There are three types of primary blood vessels and these are capillaries, veins, and arteries and the function of capillaries to connect arteries and veins, the function of veins to carry blood back to heart, and function of arteries is to take blood away from heart.
<h3>What is blood vessel?</h3>
A structure whose shape is tubular that contain blood through the tissues as well as organs and these are of three types, the capillaries which is known as smallest blood vessel and the function in to connect vein and arteries. The second type of blood vessel is veins that carry blood back to heart. The third type is artery that carry blood away from the heart.
The blood vessel may contain either pure or impure blood and it plays a vital role in the proper functioning of body.
Therefore, there are three types of primary blood vessels and these are capillaries, veins, and arteries and the function of capillaries to connect arteries and veins, the function of veins to carry blood back to heart, and function of arteries is to take blood away from heart.
