This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area
sashaice [31]

<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>

hodyreva [135]

Answer:

Fibers and the Ground Substance make the extracellular matrix...

Explanation:

Connective tissue is composed of fibers, cells and the ground substance that gave the it the overall physical appearance. Chemically, the extracellular matrix is made up of minerals, water, Proteoglycans and a large network of fibrous protiens. All of these help connective tissue to maintain the structure.

Why do you think meteorologists use a cone-shaped area for the hurricane’s path instead of a straight line?
Finger [1]

A hurricane grows in size before it makes landfall, so a cone is a natural choice for a path; the width of the cone grows larger along its length just as the radius of a hurricane grows along its path.
