Answer:
Pericardial sac has protective tole
Explanation:
Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:
- the outter coat-parietal pericardium
- the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).
Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.
I would say A. Either tall or short
When Mendel crossed purebred short plants with purebred tall plants, all of the offspring were TALL
The pure-bred tall plant dominated the short
The answer to the question is PCR
During metaphase 1, the spindle fibers attach to the centromeres of each chromosome. Both kinetochores of each sister chromatid pair are turned toward the same pole. And 2 members of each chromosome pair (sister chromatids) are pulled into each new cell during anaphase 1.
I think the answer you want is they are called chromatids.
Answer:
The light bulb will have the same mass on the moon as it will on earth. The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. For instance, if you measure your mass on Earth and then measure your mass on the moon, your mass will remain the same. The same theory applies to any object with mass.
