One hypothesis that has been proposed to explain the development of viruses suggests that viruses were beneficial because they a
llowed for rapid gene transfer, especially in prokaryotic cells, and therefore increased genetic diversity. If most bacteriophages were temperate, then this could have increased horizontal gene transfer between prokaryotic cells and potentially could have increased fitness. With respect to this hypothesis, why would it matter whether the bacteriophages were temperate or virulent? a. Temperate phages are capable of lysogeny and their genetic material can be integrated into the host genome, causing damage rather than increasing fitness.
b. Virulent phages are capable of lysogeny and their genetic material can be integrated into the host genome, causing damage rather than increasing fitness
c. Temperate bacteriophages are capable of both horizontal and vertical gene transfer, allowing a wide range of ways to increase genetic diversity. Virulent bacteriophages are not capable of either.
d. Temperate phages don't immediately kill their hosts.
Temperate phages don't immediately kill their hosts.
Explanation:
There exist phages that have shown the capability to alternate lytic and lysogenic life cycles, where don't kill the host cell. This feature allows a phage to reproduce without killing the host cells, thereby having higher probabilities of replicating its genetic material
Energy and matter characterize both physical and biological systems. These systems are defined both by the types of energy and matter they contain and by how that matter and energy move through and between systems. ... This means that energy and matter can change forms but cannot be created or destroyed.
My hypothesis is that the Hawaiian Island chain was formed by a hot spot in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. My data supports my hypothesis because as the plate moved over the hot spot, the islands that make up the Hawaiian Island chain were formed.
