1) The limbs of a bat and the forelimbs of a bird is an example of Analogous structures
2) The arm of a human and the arm of chimpazee is an example of Homologous structures
3) Frogs and salamanders is an example of Homologous structures
<span>Homologous structures, are organs or systems of different living beings
that have a common origin, but different adaptations. For example, the
extremities of a dog and a dolphin, are homologous, have similar bones, only
that some adapted to the race and others to swimming. On the other hand,
analogous structures are organs or systems of different living beings that do
not have a close origin in common, but are adapted to the same environment, for
example, fins of fish and dolphin fins, the function is the same, the origin is
different; or the wings of birds and the wings of insects.</span>
Answer:
boron , because the protons and electrons are 5 . and we all know that boron = 5.
Answer;
-RNA
-RNA is the molecule that demonstrates the widest range of functions due to its ability to adopt multiple conformations.
Explanation;
-When RNA molecules folds, they often does not adopt a single, well-defined conformation. The folding energy landscape of an RNA is highly dependent on its nucleotide sequence and molecular environment.
-RNAs, particularly highly structured RNAs such as ribosomal RNA, exist in multiple conformations, many of which are likely to affect their function. Thus, when describing RNA structure, it is more accurate to discuss an ensemble of conformations instead of a single structure.
