The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment. Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
<span>in an environment where there is little or no oxygen. aerobic respiration requires oxygen ad when it is not present fermentaion (anaerobic respiration) occurs because it works when oxygen isn't there</span>
The answer would be A . stem cell research exploits fetuses and a mothers eggs because it is the only one that says something negative about stem cell reaserch, hope this helps :))
Answer:
Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
4 Types:
1. P-type ATPase: sodium potassium pump, calcium pump, proton pump
2. F-ATPase: mitochondrial ATP synthase, chloroplast ATP synthase
3. V-ATPase: vacuolar ATPase
4. ABC (ATP binding cassette) transporter: MDR, CFTR, etc.
