<h2> Ecological Footprint</h2>
The ecological footprint is an indicator that accounts for human demand on global biological resources. If a person observed his ecological footprint, there will be less environmental problems like carbon emissions, lack of fresh air, global warming and increased environmental pollution would be reduced.
<h3>Impact of ecological footprint</h3>
One of the four categories of ecological footprint can serve as an environmental indicator because the category causes impact on the environment which leads to change in the environment so we can conclude that the category of ecological footprint can serve as an environmental indicator.

D. Brain activity doesn't necessarily cause behaviour just because they coincide.
Explanation:
- Neuroscience is the study of the neurons. This deals with how the nervous system develops, the structure of the nervous system and its actions.
- Neuroscientists are focusing on the brain and its impact on cognitive functions and behaviour.
- Scientists proved that the chemicals present in the brain are responsible for our general state and mood that we are going through. Damage of brain cell will affect our impulses and the impulsive behaviours.
The endoplasmic reticulum is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum. It usally has ribosomes attatched to it.
