Answer:
Prokaryotic cells reproduce by a process that is called binary fission.
Explanation:
The DNA in such cells is contained in a single circular chromosome called a plasmid within the cytoplasm. The reproductive process starts with the replication of the chromosome.
Answer:
1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.
2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.
Explanation:
Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.
With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
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.
Answer:
The correct option is : d. Syncytia
Explanation:
Syncytia are the multinucleated cells formed from multiple fusions of the uninuclear cells.
During a infection, an infected cell fuse together with the neighboring host cells, leading to the formation of large multinucleated cells, called syncytia.
Viruses like herpesviruses, induce the formation of multinucleated syncytia cells.
