Biodiversity is the variety and variability of life on Earth. Many areas within the tropical zones are considered biodiversity hotspots and are home to the world's most rare and endangered species.
Answer:
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.

Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).
Hi There!
Tell me a little about prokaryotic and eukaryotes.
What do these types of cells have in common?
How are they different?
2 very common similarities between the types of cells is that they both have a certain type of structure and all cells have a plasma membrane, DNA, ribosome, etc. They are different in a way that eukaryotes have a "membrane-bound organelle" which usualy includes it having a nucleus. Whats cool is that eukaryotes can be multicellular or singled celled> For Example, plants, insects, and fungi. Prokaryotes don't have a nucleus or organelle (membrane bound).
Hope This Helps :)
