DNA is able to fit into a cell because of its shape. DNA is a double helix that can bend and twist in all sorts of directions. An easier example to visualize is a spaghetti noodle in a bowl. Stretched out straight, it wouldn’t fit in the bowl, but once coiled or twisted up, it would conform to the shape of sand bowl. Well, DNA can coil up just like a noodle can, which gives it the ability to become compact enough to fit into the nucleus of a cell. The way DNA molecules can all fit into the cell is because they coil around histone proteins, which once in a tight enough coil, become nucleosomes which can stack to then become chromatin. That is how about 6 feet of DNA can be squeezed into a microscopic cell.

The mesoderm is a layer of the embryo, which will become the circulatory system, bones, muscles, excretory system, and reproductive system.

-The embryonic endoderm develops into the interior linings of two tubes in the body, the digestive and respiratory tube. the lining of the follicles of the thyroid gland and the epithelial component of the thymus.

-Ectoderm develops into parts of the skin, the brain and the nervous system. Mesoderm gives rise to bones, muscles, the heart and circulatory system, and internal sex organs.

Why can’t you feel the force of attraction between you and mars
Nana76 [90]

The gravitation force is inversely proportional to the radius or the distance. So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.
