Answer:
fishes
Explanation:
A progenitor feature found in early boney fish served as the basis for the development of the vertebrate lung.
What are vertebrate lungs?The lung of modern vertebrates evolved from a structure that was present in the ancestors of early boney fish.
Lungs in vertebrates originated as extra air-breathing organs in primordial fishes and were ventilated by buccal pumping when they first appeared. In more modern fishes, the organ formerly known as the lungs has been replaced with the hydrostatic swimbladder. This fundamental kind of unicameral lungs and the buccal pumping ventilation observed in these lungs can also be found in more modern amphibians.

Which statement best describes cancer cells?
A.cells that go through mitosis successfully
B.cells that continue to replicated even when not needed and does not stop
C.cells that move to G0,the resting phase
D.cells in hypotonic, solution to burst
Answer:
B!
Explanation:
Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.

Select all of the arguments that are supported by the diagram depicting the lytic cycle of viral replication. A) Viruses use a host cell to replicate their genome. B) A single virus can infect multiple cells at the same time. C) Viral replication can exponentially increase virus numbers. D) Viruses destroy host cells upon their release from the cell. E) Viruses use their own organelles for replication of viral components.
Answer: A, C, and D
Explanation: i just did it on usatestprep
The arguments that are supported by the diagram depicting the lytic cycle of viral replication are as follows:
Viruses use a host cell to replicate their genome.Viral replication can exponentially increase virus numbers. Viruses destroy host cells upon their release from the cell.Thus, the correct options are A, C, and D.
What is the Lytic cycle?The lytic cycle may be defined as a type of cycle that involves the process of lysis and destruction of the infected cell and its membrane. This process occurs when a virus has completely infected a cell and replicates new virus particles by the activity of bursting the cell membrane.
The lytic cycle is considered one of the two cycles of viral reproduction, the name of the other is the lysogenic cycle.
During the lytic cycle, the virus uses a host cell to replicate its genome. After occupying the host cell for the same activity, viral replication can exponentially increase virus numbers. And finally the destruction of cells and release themselves from the cell.
Therefore, the correct options for this question are A, C, and D.
