Answer:
The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
The main reason for the difference in the mass extinction occurring today and previously is the pace of the current extinction. The extinction is taking place globally and involves hundreds of species at the same time. In less than 50 years, we have lost numerous species. In contrast to this, previously during the mass extinction, only a few species were lost, and other managed to survive. But, not the status is opposite due to the magnitude of the extinction.
Answer:
Pressure, P = 28.2 kPa
Explanation:
Given that,
Number of moles, n = 0.54 mol
Volume of ideal gas, V = 35.5 L
Temperature, T = 223 K
We need to find the pressure of ideal gas. The equation of ideal gas is given by :
R is gas constant
P is pressure
So, the pressure of the gas is 28.2 kPa.
Prokaryotic cells are cells that can function independently. They consist of everything needed for that cell to nourish itself and to grow and reproduce.
<span>To break a protein down into its amino acids you will need enzymes. Enzymes
are biological molecules (proteins) that act as catalysts and help
complex reactions occur everywhere in life. Let's say you ate a piece of
meat. Proteases would go to work and help break down the peptide bonds between the amino acids.
