<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>

Explanation:
The beaks are in direct correlation with the type of or amount of food they are consuming.
Answer and Explanation:
There are three basic steps as initiation, extension and termination which occur in both eukaryotes and prokaryotes. For transcription of a gene to occur, the DNA double helix unwinds over a short region.
initiation: RNA polymerase enzyme is linked to specific portions called as promoter in DNA to start RNA synthesis after the DNA unwinds.
Elongation: the enzyme synthesizes RNA strand along the DNA chain.
Termination: RNA synthesis continues along the DNA strand until it encounters a signal representing termination of the process. The termination process happens as the transcription complex separation takes place on the DNA sequence.
When assembled in the nucleus,mRNA peels off and moves to the cytoplasm. Here, it attaches to the ribosomes.Protein synthesis is started with AUG codon which is at the beginning of the mRNA-carried code. As the mRNA moves along the ribosome its information is translated into the appropriate amino acids which are assembled into a polypeptide. this is called translaton.
