Answer:
The correct answer is - option D. lytic cycle.
Explanation:
The lytic cycle is one of the two viral reproduction cycle. Generally, it is the major reproduction cycle. In this cycle reproduction of the viruses takes place inside the host cell and produce more viruses. In the production of the more viruses the host cell and it''s destruction takes place in the end. The 5 steps that takes place are as follows:
1- attachment - viruses attach to the cell.
2-penetration- only nucleic acid or genetic material is injected into the host cell through the hole made by the tail fibers and enzymes.
3- synthesis - replication of viral nucleic acid and protein and envelope.
4- assembly - assembling of the new viruses formed.
5- release.
Thus, the correct answer is - option D.
Commensalism is an interaction in which one individual benefits while the other is neither helped nor harmed. Example: Orchids (example of epiphytes)
My answer may not be precise, but I believe if you changed your question to "The presence of these structures indicates that the student is looking at a cell of what organism", then I would safely say a plant, because plants, unlike animals, have cell walls in addition to cell membranes. :) Hope this helps!
Answer: ionic, covalent, metallic bonding
Ionic - ionic bond also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Covalent - occurs when pairs of electrons are shared by atoms.
Metallic - formed between positively charged atoms in which the free electrons are shared among a lattice of cations.
Hope this helped!
If the results of an experiment have different conclusions, something must have changed. these are called **variables**. if more than one variable is changed, the result would be different. because the total conclusion is different, it is a hypothesis, because it is not universally true.
