A balance that performs in an enclosed compartment with no air currents to disturb is called an analytical balance.
Analytical balances are instruments used for precise and determination of mass of matter. They are accurate and very precise instruments. They require a draft-free location on a solid bench that is free of vibrations.
Analytical balances of today are digital and have built in calibration weights to maintain accuracy. Older versions usually require to be manually calibrated using specific standard weights.
The building blocks of lipids are one glycerol molecule and at least one fatty acid, with a maximum of three fatty acids.
Hope this helped you, and have an amazing day.
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
Table salt contains iodine in it now.
The difference is that mitosis produces two diploid (2n) somatic cells that are genetically identical, but meiosis produces four haploid (n) gametes that are genetically unique from each other.
