A rhizoid<span> (such as is found on the gametophytes of bryophytes or ferns) is basically just a filament that anchors the plant to the ground. A </span>root<span>, on the other hand, is a sophisticated structure containing many differentlayers including vascular tissue, playing a key role in water and nutrient uptake</span>
Bacteria and restriction enzymes
,use enzymes to cut (and thereby destroy) foreign DNA (such as viral DNA), which would restrict the growth of the virus; own DNA is protected in some way (often by addition of methyl group CH3) to the sequence recognized by enzyme (thus preventing enzyme from binding there)
The amniotic egg, which is present in animals such as reptiles, birds, and mammals, is a good example of homo-logy.
<h3>What is homo-logy?</h3>
The term 'homo-logy' makes reference to the same evolutionary origin (ancestor) for a given structure.
A structure and/or sequence is homo-logous when it derives from the same evolutionary ancestor.
Conversely, an analogy means that the structure and/or nucleotide sequence do not share an evolutionary origin.

Answer:
The correct answer is B) binds to the complementary sequence of target mRNAs
Explanation:
Double stranded RNA can be used to block the expression of target mRNAs.
At first the introduced double stranded RNA is being separated into single stranded RNAs .One of the Single stranded RNA is degraded.
The remaining Single stranded RNA binds to the target mRNA by complementary base pairing and blocks the expression of that single stranded RNA.
