the answer is thrombocytes
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.
Meristem at the tips of stems and roots produce rapid growth in plants. Meristem is a tissue that is mostly found in plants. Meristematic cells are responsible for the plant's rise and to keep the plant growing.
Answer:
1st law of thermodynamics- energy can not be created or destroyed
2nd law of thermodynamics- energy becomes less useable
-only ten percent of energy in the producer level can be transferred to the next level and so onto the next level
- the lost energy either becomes heat or waste
