Answer:
Yes, the operating system is the computers internal organization
Explanation:
Sympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography, sympatric and sympatry are terms referring to organisms whose ranges overlap so that they occur together at least in some places.
Answer: radio telescopes can be used.
Explanation:
Radio telescopes can be used to see through the dust and the star being born. The stars are born into clouds of gases in the space. Due to gravity more and more gas get collected and it forms a clump. When the clump get big enough the hydrogen atom crash each other to form the helium. The clump of gas becomes a star. The radio telescopes can be used to take pictures of these stars within the clump of gas. It can also be used to take picture of fusion of gases within a star to initiate the formation of new star.
Epiblast and Hypoblast are common in the development of both birds and mammals.
Hypoblast is the second layer of the embryonic disc that creates the yolk sac, Epiblast is one of the two layers that creates the three basic germ layers (ectoderm, definitive endoderm, and mesoderm), amnionic ectoderm, and extraembryonic mesoderm.
The embryonic disc is made up of two parts: epiblast and hypoblast.
The epiblast and hypoblast are formed by layering the core cell mass. As a result, the inner cell mass gives rise to the epiblast and hypoblast.
Additionally, epiblast cells are topped by hypoblast cells.
Both layers are formed before implantation and gastrulation.

Answer:
PERICARDIUM MEMBRANE
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
Our heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart.
PERICARDIUM FLUID
Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. ... This serous layer has two membranes which enclose the pericardial cavity into which is secreted the pericardial fluid.
