Answer:

The correct answer is "T" True.

Explanation:

There are different kind of balances that could be found in the laboratory according to the amount of material that needs to be weighted. The most widely used is the analytical balance which can measure as low as 0.1mg. However, there are specialized analytical balances that can measure up to 0.005 mg. Other kind of balance found in laboratory are the toploading balances, which measure as low as 20 grams and up to 64 kg.

How does the lipid portion help maintain water concentration on each side of the bilateral?

vaieri [72.5K]

Answer:

Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?

It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

In the lungs, oxygen diffuses into the blood and is loaded onto hemoglobin for transport. In the tissues, oxygen is unloaded fro

emmasim [6.3K]

Answer:

D. partial pressure of oxygen

Explanation:

Partial pressure refers to the force applied by an individual gas per unit area in a mixture of gases which is measured in mm of Hg. The partial pressure determines the movement of the gas molecule in the system.

In the given scenario, the oxygen transport through the blood along with other gases like carbon dioxide and other minute concentration but the gaseous exchange between the lungs and the blood, between the blood and the tissues depends on the partial pressure of the oxygen. The oxygen moves from the higher pressure to lower pressure therefore partial pressure is the determining factor.

Thus, Option-D is correct.
