Answer:
Sometimes molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane. Facilitated diffusion is the diffusion of substances with the help of transport proteins in the plasma membrane. These special proteins are called channel proteins or carrier proteins, and they are attached to the cell membrane. In fact, they go through the cell membrane, from the inside of the cell to the outside. Facilitated diffusion is used for molecules that cannot diffuse rapidly through cell membranes on their own, even when the molecules are moving from high to low concentration areas. An example is the sugar plants and animals use for energy, called glucose. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient so it does not require the use of cellular energy.
Both types of tissues are made of differentiated cells that have a specific function.
Both types of tissues contain cells that lost the ability to divide
I thought it was savannah but grasslands could be it too.
<h2>Answer:</h2>
The three amino acid will be Tyrosine, Asparagine and Lysine respectively to sequence.
<h3>Explanation:</h3>
UTC GTU TTG
First the thymine in the sequence is changed to A, adenine because in the mRNA only three types of nucleotides are allowed which are Adenine, thymine and Uracil.
So the sequence will be:
UAC GAU AAG
These codons will be read by tRNA producing the polypeptide sequence of amino acids which are as follow:
Tyrosine Asparagine Lysine.
