Answer:
Inorganic fertilizers are not entirely composed of the nutrients needed by the plants. It also contains salts and other compounds. These are not absorbed by the plants so they are left behind in the soil and build up over time.
Vestigal organs are organs that, as we evolve, the organs loose their purpose and have no function anymore. The appendix is a vestigal organ
Hope this helps
Answer:
The characteristics of cells to divide and convert into specialized cells makes it possible for the different levels of organizations to occur. Specialized cells perform specialized functions which are necessary for the body of each organism. The working of these specialized cells allows the formation of the specialized tissues and the levels of organizations continue. Hence, we can consider the ability of the cells to multiply and divide into specialized cells as the basic characteristic due to which levels of organization occur.
Answer:
adsorption, penetration, biosynthesis, maturation, release
Explanation:
The virus after infecting the cell produces several progenies which after reaching a certain number cause the lysis of the cell and are then released out from it. This process of entering the host by the virus and then lysing the cells to be released is termed as a lytic cycle.
There are 5 stages involved in this lytic cycle:
1. Adsorption - when the virus finds its attachment site on the bacteria it gets attached to the viral receptor and then is adsorbed on the bacteria, this is the first step required to gain entry into the host.
2. Penetration - once the virus is attached to the host the next step is to penetrate it and enter inside the cell. For this, the virus secretes lysozyme and then inserts its genetic material inside the cell.
3. Biosynthesis - this stage involves the utilization of the enzymes and nucleotides of the host to make up the DNA of the phage.
4. Maturation - once the phage DNA is made the next stage is to assemble the phage DNA with the capsid and this is termed as maturation.
5. Release - this step involves the breakage of the plasma membrane of the host cell and the release fo the phage particles.
Answer:
A and C
Explanation:
IM pretty sure anyway i just finished up my biology so im not 100% sure but i know it has to do with ammonia and nitrite or nitrate so thats my best guess.
