For example, enzymes are proteins that speed up chemical reactions in the body and hormones, like insulin, are proteins that regulate the activity of cells or organs. Some proteins transport materials throughout your body, such as hemoglobin, which is the oxygen-transporting protein found in your red blood cells
To maintain a line of pure-breeding peas, selective breeders would use a technique called artificial cross-pollination. This is a technique were breeders transfer pollen from the anthers of one pea plant (male parent) to a stigma of a flower (female parent).
This technique was developed by Gregor Mendel, the founder of the science of genetics. He was a monk who dedicated his time in research about how genes of plants are carried over through specific species. In his controlled experiment he used the pea plant because they are cheap and readily available from merchants who sold them in different classifications. He also used pea plants because they have the capacity to self-pollinate or cross-pollinate.
A team of students is performing an experiment to determine how the speed of a reaction between HCl and Na2CO3 changes with temperature. The aspect of the experiment that does not have to be kept constant would be the initial concentrations of the reactants. Hope this helps. Have a nice day.

Coccidioides immitis is not a member of domain bacteria.
Coccidioides immitis is a dimorphic fungus that causes the fungal disease; coccidioidomycosis. Coccidioides immitis is mainly found in soils and it exists in two different forms (saprophytic and parasitic). When Coccidioides immitis enter a host, their spores separates from the hyphae and develop into round structures (spherules) that divides to form endospores which causes infection within the host.
