All of the chordates have these slits as embryos
Answer:b. an mRNA transcript to which multiple ribosomes are attached
Explanation: polysome consist of mRNA complex and two or more ribosome coming together to translate mRNA into a polypetide or amino acid. It helps produce many polypeptide from a single mRNA.
Different ribosomes bind to the mRNA at different time elongating the polypeptide chain. We have the free( non-poly A ) and memberane bound (poly A) polysome.
<h2>Rhizoids absorb water and nutrients from the surrounding soil.
</h2>
Explanation:
Rhizoids are primitive root like structure in lower plants like bryophytes and sin fungi. Rhizoids are usually unicellular. However many plants exhibit multicellularity. Rhizoids functions as the roots in these plant,by absorbing water and nutrient from the surrounding soil. They may contain enzymes which helps in extracellular digestion in orgsnidm which have saprotrophic mode of nutrition.Rhizoids provide a little anchorage to the substratum.
