The 2 major components or parts that compose or make up the plasma membrane of a eukaryotic cell would be the phospholipids arranged as a bilayer, having phospholipids arranged side by side in an upright and inverted manner, allowing for the hydrophobic and hydrophilic regions to interact respectively, and also Protein molecules, more specifically Transmembrane Proteins and Integral Proteins.
Answer:
The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .
Explanation:
Answer:
9 per 1,000/yr.
Explanation:
The population growth rate is 9 per 1,000/yr.
The rate of growth of population is determined by the following formula:
<em>Growth rate = B - D + I - E</em>
<em>Where B = birth rate, D = death rate, I = immigration, and E = emigration</em>
In this case, B = 26, D = 15, I = 7, and E = 9. Substitute these values into the equation of growth rate.
Growth rate = (26 - 15) + (7 - 9)
= 11 - 2 = 9
<u>Hence, the growth rate of the deer's population is 9 per 1,000/yr.</u>
Ans.
Lipid bilayer is made up of two layers of phospholipids, which show polar, hydrophilic (polar) phosphate groups on surface of cell membrane and non-polar, hydrophobic (non-polar) tails on inner sides. The hydrophobic nature of cell membrane allows transport of small, hydrophobic molecules more quickly than larger, hydrophilic molecules.
Thus, 'the non-polar, uncharged or small molecules, such as water, oxygen and other gases, will diffuse across the lipid membrane most quickly, while the polar, charged or large molecules, such as ions, proteins, and salts, will diffuse most slowly.'
