Answer:
In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. 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. An example of active transport in human physiology is the uptake of glucose in the

Answer:
Experimental or interventional studies compare the effect of treatments or interventions with control in humans. Placebo or different treatment(s) or intervention(s) may be used as control. Experimental studies have to be transparent and evidence-based. Two examples include clinical studies as well as observational drug studies.
Answer:
False
Explanation:
Indoor pollution is rather more dangerous and is caused by harmful chemicals. Due to restricted area, the density of the pollutants is higher indoor, and thus, they are build up more inside.
Fracking process is dangerous and hazardous for all our environment and its organisms.
<h3>What is your opinion about fracking?</h3>
Hydraulic fracturing is a type of oil and gas drilling that occurs across the country. Due to no safety regulations, it can polluted groundwater, pollute surface water, and harm wildlife.
So we can conclude that fracking process is dangerous and hazardous for all our environment and its organisms.
