Heat Creation. Fish, like all animals, create heat from metabolic activity. ...
Heat Loss. Fish lose metabolic heat through their gills. ...
Homeostasis. Most fish are poikilothermic, which means their body temperature changes with ambient temperature. ...
Exceptions to Pure Poikilothermy.
Step 1-Light Dependent. CO2 and H2O enter the leaf.
Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
Step 3- Light Dependent. The electrons move down to enzymes.

Coronaviruses are viruses that affect animals and humans in the respiratory tract. they can be in common colds, phneumonia and can also effect the gut. Coronaviruses were first identified in the 1960's. In the case of humans this is commonly caught in the winter months or early spring. So far there is currently no cure for this illness.
The ability of microtubules to undergo rapid <u>depolymerization </u>and slower<u> polymerization</u> is associated with the ability of the <u>spindle apparatus</u> to explore the cell and locate chromosomes.
<u>Explanation:</u>
Microtubules are tubulin polymers that make up part of the cytoskeleton and provide eukaryotic cells with framework and shape. These are formed by polymerizing the dimer into protofilaments of two globular proteins, alpha and beta tubulin, which can then be combined laterally to form the microtubule, a hollow tube.
Tubulin dimers can attach two GTP molecules, one of which may be hydrolyzed following assembly. Tubulin dimers are in GTP-bound state throughout polymerization. Once hydrolysis reaches to the peak of the microtubule, a rapid depolymerization and shrinkage is initiated.
