Answer:
New cells are naive to the infectious cells who attack it or they are not well prepared to deal with the different scenarios. But, the cells who are attacked before has the set or sequence of the viral or bacterial genome strand been identified by them, which leads to more safety or protection from these foreign bodies.
Explanation:
- Mechanism To attack a host cell:
The viruses and other infectious material enters and attacks the host cell, by breaching its membrane wall and installing or leaving a gene of its own inside the cell. Which then combines with the genome of the cell and it goes through the process of replication, translation etc,along with the host cell machinery. Which then spreads the specific gene strand more in the environment
- <u>Camouflage obtained by the infectious cell to hide it self:</u>
After the genome enters the host cell at first it does not recognizes the strands or foreign cells, as they cover there body with a camouflage sort of membrane and they look more like the body cells.
- <u>Reactions by the host cell and as a whole the body:</u>
The organisms detects the genome of the infections cells or strand, as they store the data about it in its server or database. As if the next time they were under attack then precautions will be there by the host cell to deal with it.
As for the cell who are never attacked before will be less safe to deal with these foreign bodies.
uhmm...
I was expecting a multiple choice
Answer:
<em>The correct option is D. It is carbon dioxide released by respiration.</em>
Explanation:
The process by which ATP is abundantly formed in organisms is termed as cellular respiration. Cellular respiration can be described as a process in which carbon dioxide and water are produced from glucose and oxygen. ATP molecules are synthesized by this process which are used for cellular activities.
Hence, the substance X in the investigation shows carbon dioxide which was produced when the yeast cells began to respire. Yeast cells can respire either in the presence of oxygen or without oxygen.
C. both biotic and abiotic factors in earth most ecosystems have both abiotic and biotic systems. They actually need both in order to survive.
Plankton is the answer to your question.
