Answer:
channels and chain-like structures
Explanation:
The plasma membrane contains channels that favor the transport of materials from both sides, i.e., from the intracellular medium to the extracellular environment. Membrane channels are a class of proteins that enable the passive transport of ions and chemical compounds by using the electrochemical gradient in both sides of the membrane. For example, channel proteins in the cell membrane known as aquaporins enable the transport of water across the cell membrane much more rapidly than by diffusion across this barrier.
Answer:
Explanation:
1. The DNA: the DNA is the template from which the mRNA is produced, ie the non coding template strand of one of the two DNA strand is utilized in transcription.
2. The mRNA determine the amino acid sequence of protein. After the production of mRNA from the DNA, the mRNA is then utilized to carry out translation which involve the synthesis of polypeptides: chain of amino acids.
3. The tRNA aids in translation by care the amino acid read on the mRNA and also carrying the complimentary anticodon to match the codon for the amino acid on the mRNA.
4. THE rRNA also known as the ribosomal RNA is what makes up the one of the main component of the ribosomes. A major part also helps in the period bond formation
These animals have morphological similarities due they are analogies. These types of similarities do not share a common origin.
<h3>What are analogies?</h3>
Analogies are similar structural features that may have the same function but do not exhibit a common evolutionary origin.
Conversely, homo-logies are characteristics that show a common evolutionary origin.
Analogies appear during evolution as a consequence of adaptation to similar environmental conditions.
