A rock that forms when magma hardens beneath Earth's surface is called an intrusive igneous rock.
Density is the amount of mass in a certain Volume. Air pressure results from a column of air pushing on an area. A measure of how tightly air molecules are packed together is called Density
Option 1B, 2A and 3B
Explanation:
Density is the mass amount of a substance held up to its volume in certainity to a ratio formula. So basically, density = mass per volume of a substance.
Air pressure, on the other hand, is the pressure which is being experienced by the columnar weight of air, when the air in an area is being pushing down.
The amount of mass of the air in the prescribed volume of air constitutes its density and hence the air molecules packed tightly in the volume presumed carries a mass and is noted as the density.
Answer:
D. membrane-enclosed organelles
Explanation:
Protein expression refers to the way in which proteins are synthesized, modified and regulated in living organisms.
Hope this helps :D
In order for the scientist to know if the organism makes a
protein in the skin and for he or she to be able to analyze it with the use of
skin sample in determining its presence, the scientist should look and analyze
the cells found in the skin. He or she must be directed at the cell’s
mitochondria as where the protein synthesis occurs and to be able to determine
if protein is present, the scientist should find the Amino Acids.
