Answer:
A peptide bond must form between subunits of mRNA
Explanation:
Translation occur in the RIBOSOMES and it is the process where protein is produced by reading the genetic code of messenger RNA.
For translation to occur,A peptide bond must form between subunits of mRNA because it is through the formation of peptide bond between subunits of mRNA that the small ribosomal subunit binds to the start of the mRNA sequence. Then a transfer RNA molecule that carry Amino acids methionine binds to the start codon of the mRNA .The start codon in all mRNA molecules has the sequence AUG and codes for methionine.
It's probably c most likely

<u>Answer:</u>
Free-living flatworms have developed a nervous system which helps them to sense the food. They have a head at one end of the body and each side of the head has sensory cells. These cells help them to sense chemicals and other movements around them.
While Parasitic flatworms don't have any nervous or digestive system as they live on the food digested by the host. They have special hooks attached to their head which help them to attach a host. They have developed some covering called 'teguments' which protect them from digestive liquids.
The correct answer for this question is (A) Groups of cells form tissues.
In multicellular animals, a group of similar cells alongwith inter-cellular substances perform a specific function. Such an organization is called tissue. All complex animals consist of only four basic type of tissues. These tissues are organized in specific proportion and pattern to form an organ like stomach, lung, heart and kidney. When two or more organs perform a common function by their physical and/or chemical interaction , they together form organ system, eg., digestive system, respiratory system, etc. Cells, tissues, organs and organ system split up the work in a way that exhibits division of labour and contribute to the survival of the body as whole.
