A major problem in sending space probes to Jupiter is that the planet has no solid surface on which to land, as there is a smooth transition between the planet's atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures within Jupiter
The answer is B
Germination is when a seed starts to grow after a period of dormancy
Answer:
RNA world hypothesis.
Explanation:
RNA is present as the genetic material in some viruses only. RNA is produced from the template DNA by the process of transcription and helps in the protein gene expression.
According to RNA world hypothesis, RNA is considered to be the first genetic material as it has the ability to store the genetic material. The oxyribose sugar makes the RNA more reactive than the DNA molecule. The RNA also has the ability to work enzyme known as ribozyme. Hence, RNA has the ability to store the information and acts as catalyst.
Thus, the answer is RNA world hypothesis.
Answer:
Both plant cell and animal cell rely on cell division for their growth and development.
Explanation:
Cell division is very much important in case of both plant cell and animal cells because
1 Cell division helps in the transfer of genetic material from parental cell to the daughter cell thus playing a significant role in cellular reproduction.
2 We all know that cells are the structural and functional unit or basic unit of life.Cell division in case of both plant and animal result in the formation of new cells which further undergo cell division to generate new cells and so forth.Thus many cell are formed which together leads to the formation of various body tissues.
3 Cell divison also helps in wound healing.During wound healing the damaged cells are replaced by newly formed cells.
