Answer: All of these are true (besides the one that says that none are true...).
Explanation:
The ecological succession is a slow change in the living community of the ecosystem along with the changes occurring in the non-living environment until the ecosystem attains stability.
The primary succession can be defined as the initial level of succession. This succession begins in the primitive environment. The soil develops after the weathering process of rocks.
The secondary succession begins in the region where life forms existed before and the area begin damaged by the catostrophic event like forest fire, earthquake and other type of calamities. Some remaining plant parts can give birth to the entire colony of plants.

About 11 to 15 days after conception the zygote attach to the uterine wall
Bacteria multiply by binary fission, which results in exact copies (clones) of the parent cell. There for B, 100 would be the answer.
Answer:
<h2> Replication: DNA into DNA, and RNA primer are required;</h2><h2>Transcription/RNA processing: pre mRNA and then mRNA;</h2><h2>Translation: tRNA, rRNA</h2>
Explanation:
1. During replication, a semi-conservative copy of a DNA molecule is made with the help of various enzymes and RNA primer.
2. Transcription/RNA processing: mRNA
During transcription, the DNA "message" ( in the form of codon) is copied into mRNA.
3. Translation: tRNA, rRNA
During translation, the information carried in the mRNA is translated into protein with the help of molecules of tRNA and rRAN to build a protein on the ribosomes.
