The dependent variable alters
The two jet streams that affect our weather in the continental US are the polar jets and the subtropical<span> jets. They are responsible for transporting weather systems that affect us. The polar front is the boundary between the cold North Pole air and the warm equatorial air</span>
The answer should be the refractory period
Question
<em>Define enzyme concentration.</em>
Answer:
<em>Substrate concentration is the amount of substrate present that can be turned into product and is most commonly measured in molarity (moles per liter). The concentration of substrates is often used to measure enzyme activity, which is based on the rate of a reaction (product formed over time).</em>

Answer:
The neutrophil forms multiple lamellipodia extensions
Explanation:
Neutrophils are white blood cells (granulocytes) which comprise the first line of defense in the innate immune system. The lamellipodium (in plural, lamellipodia) is a cytoskeletal actin extension found in mobile cells, whose main functions are cell motility and migration. Rac1 is a member of the Rho GTPase protein family which is involved in actin-myosin cytoskeletal reorganization of neutrophil cells in response to microorganism infections. In this regard, it has been shown that Rac1 controls the initial uncapping of actin ends in order to regulate cytoskeleton dynamics, thus regulating lamellipodia formation. By using mice as models, researchers observed that Rac1 constitutive activation may lead to the formation of multiple lamellipodia in neutrophils.
