When stem cells grown on hard, rigid surface, then they became bone cells. Researchers demonstrate in Nature materials that human mesenchymal stem cells grown on a rigid substrate for some time become biased toward differentiating into bone-cell lineage, whereas cell grown on softer surfaces are just likely to eventually follow a bone or fat cell fate.
The answer is B) 4IF3 Hope this helps!
Aye Sir!
Dna replication so it replicates your DNA to occur
Answer:
1)
- frequencies of light-colored mice ≅ 0.74
- frequencies of dark-colored mice ≅ 0.26
2)
- frequencies of light-colored mice ≅ 0.13
- frequencies of dark-colored mice ≅ 0.87
3)
- q² = 0.74
- p² = 0.02
- 2pq = 0.24
4)
- q² = 0.13
- p² = 0.4
- 2pq = 0.46
5)
The dark-colored fur seems to have the greatest overall selective advantage
6)
Dark lava, that changed the color of the substrate, from light to dark.
7)
Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.
8)
To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
Isotonic solutions is the term used when the concentrations of solutes inside and outside a cell are in equilibrium.
Explanation:
The isotonic solution is one which have same osmotic pressure on either side of the semi-permeable membrane.
In the isotonic solution there will be free movement of only water molecules and not solutes.
isotonic solution is the solution when two solutions have equal solute concentration.
The concentration of the solution will be in equilibrium.
