A specific type of physical change is a phase change
Answer:
1. Surface (substratum) is preconditioned by environment molecules.
4. Microbes attach and detach from the preconditioned surface.
2.Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably.
3. Biofilm matures and some microorganisms escape to the plank-tonic state.
Explanation:
Biofilm is a process in which microorganism irreversibly attach and grow on the surface to produce extra cellular polymers that facilitate formation of matrix. The biofilm process takes three days for the formation after which thickness of plaque increases. There are 4 main steps in biofilm formation. Surface is preconditioned by environment molecules. The microbes attach the preconditioned surface. Establishment of extra cellular matrix and finally biofilm matures.
Answer:
Cell wall, chloroplast, and central vacuole
Explanation:
Cell wall, chloroplast, and central vacuole are present in a plant cell but not in the animal cell.
Nucleus, cell membrane, and cytoplasm present in both plant and animal cells.
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell.
The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.
Think about the actual physical process happening in the cell - the allele (or versions of a gene) are literally physical pieces of DNA strung together into chromosomes. And as the cell divides to form gametes, those chromosomes randomly assort themselves into the two new cells (conditional that each new cell gets one copy of each chromosome, in the case of gametes)...<span>
