C)through the roots..........
It is indeed A, all of the other answers would be examples of how not to conserve non-renewable resources
<u>Answer</u>:- Active transport
<u>Explanation</u>:-
There are two types of membrane transports
1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from <em>high concetration to low concentration.</em>
2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from <em>low concentration to high concentration.</em>
<em>The active transport is of two types:</em>
1. <em>Primary active transport-</em> in this type of transport <em>ATP</em> is used as an energy source to move the substances against the concentration gradient.
2.<em>Secondary active transport</em> - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.
- The membrane proteins that are associated with active transport are called as <em>carrier proteins</em>. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.
So, the <em>active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.</em>
Answer A:
The process of <u><em>photosynthesis</em></u> is occurring in image A.
Photosynthesis can be described as a process by which plants use light energy and convert water and carbon dioxide into sugar and oxygen. The sugar produced is the food for the plants. This process occurs in the leaves where chloroplasts are present. Chloroplasts trap light energy.
Answer B:
<u><em>The organelle is mitochondria. The process which occurs in the mitochondria is cellular respiration.</em></u>
Mitochondria are known as the power house of a cell. The process of cellular respiration occurs in the mitochondria. By this process, glucose and oxygen are converted into carbon dioxide and water. Energy in the form of ATP is released during this process. The energy is used normal cell functions.
