Chromatin
Chromosome, the highest packing level of DNA, is packed in nucleus. DNA strand itself is packed in chromatin. Chromatin is DNA packaging into 30nm fibers that involve DNA strand with scaffolding around DNA proteins, like histones, in eukaryotic cells’ nucleus.
Explanation:
The DNA strand is folded into nucleosomes, bead-like structures on the DNA and fold up into the 30nm fibers. During meiosis and mitosis, the chromatin is super-coiled up into thicker fibers called chromosomes. Chromosomes within the nucleus can be viewed by a light microscope in a cell in metaphase.

Homeostasis, it is the process of organisms regulating their internal conditions. <span />
Climate of Russia
This area of Russia is famous for its extreme climate with very cold winters, but warm to hot summers, although they tend to be short and wet. ... The north and northeastern areas around the Black Sea have milder winters, but frequent rainfall all the year round.
Climate of Finland
July temperatures in Finland average 13 to 17°C. February is usually Finland's coldest month, with temperatures averaging from - 22 to -3°C. In northern Finland, winter temperatures often drop as low as -30°C or even down to -50°C, sometimes with strong, cold easterly or northeasterly winds.
Climate of Minnesota
Minnesota has a continental climate, with hot summers and cold winters. ... Temperatures as low as −60 °F (−51 °C) have occurred during Minnesota winters. Spring is a time of major transition in Minnesota.
<span>A surgeon opens her patient by cutting the integument parallel to the cleavage lines of the dermis this will result in faster healing of the skin and less scaring. Scaring is a natural process, when the skin repair in itself. faster healing of the skin and less scaring is the mostly important of the patients. patients are likely to faster healing of the skin and less scaring.</span>
The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two.
We can notice one’s hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable physical look is the phenotype while the unnoticed genes responsible for such characters present in the DNA of cell of the individual is genotype.
To explain the above lines, here is the simple example of a pure red colour flowering plant (RR) is crossed with the white colour flowering plant (rr). The result of the Genotype of the F1 generation will be – Rr (Hybrid red colour), and the Phenotype of the F1 generation will be the – Red colour flowering plant.
Genotype and phenotype are the two very closely related and similar-sounding words, but their meaning is different. Our earth has a dynamic variety of organisms, present in soil, water and on land. But as the genome of each organism is different, and so there phenotypes also whether it’s their colour, height, weight or other morphological features.
