You can see the structures within the organelles of the cells (e.g the structure within a mitochondria) with an electron microscope as it has a much higher resolution than light microscopes.
Answer:
Mintu should have chosen a material with a lower specific heat.
Explanation:
When we talk about specific heat, we refer to a specific quantity of heat that is needed for a substance or material to rise its temperature. In more concrete terms, is the amount of heat required for 1 gram of substance/material to elevate its temperature by 1 degree Celsius.
This would mean that a material with a high specific heat would require a higher quantity of heat to increase its temperature, so in this case, if Mintu wanted to make the heat transfer easier between the metal iron and the other piece of metal, he should have chosen a material that could elevate its temperature by receiving a lower quantity of heat, that is a material with a low specific heat. But instead he chose a metal with a higher specific heat, which will now make the heat transfer more difficult,and that was the error.
Answer:
C
Explanation:
C contains the most Earthy elements, those elements come mostly from Earth itself but not created by any human
This is true.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient exists that allows movement of particles without expending cellular energy.
Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.
Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.
Normally the amount of plasma in whole blood is GREATER than the amount of formed elements: plasma makes up approximately -55- percent of whole blood.
Hope this helped!
