B. Half of the total genetic information
Answer: The muscle cells long oval shape helps it reach across to pull on its neighboring cells, while also cimpressing into a circular shape when the fibers contract. This it take up an optimal amount of space while not make the cell bulge in an uncomfortable and awkward way.
Explanation:
A segmented viral genome can facilitate rapid evolution of new viral strains.
Explanation:
Viruses are non-cellular entities which contain one or molecules of DNA or RNA as their genetic material enclosed inside a protein capsule.
Viruses are obligate intracellular parasites and cannot replicate outside a living cell.
The virus integrates its genome into the host genome and uses its mechanism to replicate its genome.
In other words we can say that viruses actually hijack hosts replication machinery.
The fragment of viral genome which disintegrates itself from the host genome after successful replication might carry fragments of host genome. Thus the viral genome gets modified and may evolve.
Answer:
<h2>All deuterostomes exhibit radial symmetry in their bodies.</h2>
Explanation:
deuterostomes : All deuterostomes are triploblastic and have 3 layers:
i) endoderm, ii) mesoderm and iii) Ectoderm
In deuterostomes , a mouth that develops separately from the blastopore.
Taxonomically, the deuterostomes defines as any member of the phyla (Chordata, Hemichordata, Echinodermata, etc) in which the anus appears first, and it develops at or near the blastopore.
All deuterostomes have a coelom.
All deuterostomes have a similar pattern of early embryonic development.
