Phytoplankton use carbon dioxide and produce oxygen during photosynthesis; phytoplankton, fish, and seals use oxygen and produce carbon dioxide during respiration. Which can provide the most energy in an ecosystem
Explanation:
A generic embryonic cell is different from a differentiated cell because it has a specific structure to perform a certain function. During development, cells become increasingly different from one another so that they can be specialized for specific functions.
<h3>What are embryonic cells?</h3>
These stem cells come from embryos that are 3 to 5 days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.
With this information, we can conclude that Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

is the surface where the water pressure head is equal to the atmospheric pressure
Explanation:
is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water.
Proteins also have structural or mechanical functions, such as actin and myosin in muscle and the proteins in the cytoskeleton<span>, which form a system of scaffolding that maintains cell shape. Other proteins are important in cell signaling, immune responses, </span>cell adhesion<span>, and the cell cycle. hope that helped</span>
