Enveloped viral membranes are generally ________ with associated virus-specific ________. a. A) lipid bilayers / phospholipids b
Veseljchak [2.6K]

Enveloped viral membranes are generally (C)lipid bilayers with associated virus-specific (C)glycoproteins.

Viruses are intracellular parasites that hijack the cellular machinery for their own replication. Therefore, an essential step in the viral life cycle is the transfer of the viral genome into cells. Enveloped viruses (viruses with a lipid envelope) use a two-step process to release their genetic material into the cell.

It first binds to specific surface receptors on target cell membranes and then fuses with these. Viruses and cell membranes. This last step can occur at the cell surface or after internalization of the virus particle by endocytosis or another pathway (such as micropinocytosis).

Strikingly, the virus-cell-membrane fusion process proceeds along essentially the same intermediate steps as other membrane fusions that occur, for example, in vesicle fusion at neural synapses or cell-cell fusion in yeast mating. Fusogens, special viral proteins, facilitate the fusion of viruses and cell membranes.

How does the heart pump blood from the right ventricle to the lungs and the left ventricle to the rest of the body? (mention the
netineya [11]
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Compare and contrast glaciers and sea ice
Sunny_sXe [5.5K]
The most basic difference is that sea ice forms from salty ocean water, whereas icebergs, glaciers, and lake ice form from fresh water or snow. Sea ice grows, forms, and melts strictly in the ocean. Glaciers are considered land ice, and icebergs are chunks of ice that break off of glaciers and fall into the ocean.

When water is distilled, any solutes dissolved in the water are left behind. Is distilled water hypertonic or hypotonic compared
Illusion [34]

Answer:

Hypotonic

Explanation:

Tap water contains a lot of solutes and ions that are absent in distilled water. The solution that has more solutes (more dissolved solids) will be the <em>hypertonic</em> solution.

Here, distilled water has no solutes, making it <em>hypotonic</em>.

<h3>Answer: <u><em>Hope this helps </em></u></h3><h3><u><em /></u></h3><h3>Explanation: </h3><h3><u><em>This pattern of energy transfer continues with each successive level of the pyramid. Secondary consumers receive 10% of the energy available at the primary consumer level (1% of the original energy). Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy).</em></u></h3><h3><u><em /></u></h3>
