Julli [10]
<h2>Active & Passive transport</h2>

Explanation:

  • Active transport is where a chemical reaction using ATP moves things in/out of the cell through transport proteins within the cell wall. It uses a concentration gradient to trigger the reaction (it goes against the concentration gradient in active transport)
  • Molecules move against a concentration gradient ( low concentration ―→ high concentration)
  • Cellular energy (ATP) is required
  • Passive transport also uses a concentration gradient by diffusion (hydrophobic or very small polar molecules) and facilitated diffusion via carrier proteins and channels
  • Molecules move along the concentration gradient (high concentration ―→ low concentration)
  • No cellular energy is required

Question 5
ArbitrLikvidat [17]

The environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint (option A).

<h3>What is ecological footprint?</h3>

Ecological footprint is the measure of how much biologically productive land and water area an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates using prevailing technology and resource management practices.

Living organisms make use of resources in the environment and these can either leave negative or positive effect on the environment that will affect sustainability.

Therefore, it can be said that the environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint.
