<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:
The original organism is called the <u><em>parent (ancestor)</em></u> , and new organisms are called the <u><em>offspring</em></u>.
Explanation:
Reproduction is one of the characteristics of life. Every living organism tends to give rise to another organism. The organism which gives rise to another organism is termed as the parent. The organism which is born is known as the offspring.
There are two basic methods of reproduction. An organism can give rise to another organism by the method of asexual or sexual reproduction.
During asexual reproduction, identical copies of the parent organism are made. During sexual reproduction, two organisms reproduce to produce non-identical offsprings.
Answer:
