Answer:
Plants respire all the time, but photosynthesis only happens during the day. This means that the net gas exchange from a leaf depends on the light intensity
Explanation:
Between the 2 elements, nitrogen and phosphorus the element abundant in the ocean is the answer
The molecules of air inside of an inflated balloon are very far apart and moving rapidly. They collide with other molecules and with the inside surface of the balloon. Collisions between gas molecules are perfectly elastic.
If there is less water in the bottle, then the note played is lower because there is more air to move around.
Using two different media (air and water) in glass bottles show how the speed of vibrations affects pitch.
Pitch is the way that your ear and brain order sounds based on their frequency (vibrations per second).
Rapid vibrations (high frequency) that reach your ear are categorized as a "higher" pitch, while slower vibrations (low frequency) are categorized as a "lower" pitch.
When you tap a glass of water with a pencil or spoon the water molecules vibrate and create sound waves through the water. More water means slower vibrations and a deeper tone.
The bottle with the most water will have the lowest pitch while the bottle with the least water will have the highest.
When Wanda and Marita blow across the top of the bottle, they set the air molecules vibrating and produce sound waves. In this case, more water results in a higher pitch, as opposed to tinkling the bottle. When the bottle has a small amount of water in it, the air molecules have lots of room and vibrate slower. Adding more water gives them less space to vibrate in, making them vibrate faster and producing a higher pitch.

<span>Because if we only classify animals by morphology, many animals have the same describable traits and physical structures.
Genes helped taxonomy better classify and aggregate animals.
Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. </span>This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. <span>And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.<span>
