How do bird skulls(when they are embryos) relate to dinosaurs

Answer:

The skull of a bird looks similar to that of a young dinosaur when they are at their embryo stage.

Explanation:

Bird's skull at their embryo stage looks like young dinosaur's skull. This feature gives evidence of their evolution and their ancestors. The surviving member of the feathered dinosaur family are the birds. The unique skull shape of a bird shaped like a beaker with a dome like cranial resembles with the non-flying ancient dinosaurs. This phenomenon is often named as psuedomorphism. In this phenomenon, these features of the ancestor at its embryo stage is retained by its predecessors.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

loss of sensation to pressure and touch

the dorsal column–medial lemniscus pathway (dcml) (also known as the posterior column-medial lemniscus pathway (pcml)) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.
