Answer:
The Laura tried to grow micro-organisms in culture broth medium in Petri-plates but the microbial growth was not observed even on the fourth day of culture which could be due to:
1. Laura could have not provided the correct broth medium maintaining the with pH and salt concentrations.
2. Microorganisms did not get optimal growth conditions.
3. The bacterial source could have died after the collection which could have lysed after their death and thus no longer visible.
False this could only happen if the pathologist or anthropologist was there at the time of death
This law states an organism has two different alleles for a trait and the allele that is expressed in the phenotype, masking the expression of the other allele,is said to be dominant. The allele whose expression is masked is said to be recessive.
The process of cellular differentiation is a direct result of a differiental
A. SSB prevents reannealing of the separated strands, so strands would quickly reanneal and DNA replication cannot proceed.
Single-stranded binding proteins, or SSB, appear on the strands to separate the strands. Without a separation force, the strands would simply bind back together through hydrogen bonding.
The answer is a .....hope I helped
