A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine.
AnnyKZ [126]

Answer:

The correct answer is -

Thymine: 20%

Guanine: 30%

Cytosine: 30%

Explanation:

According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.

So, A+G+T+C = 100

20+20+G+C

100-40 = G+C

60= G+C

as we know G is equal to C similarly A is equal to T

Thus, G = C= 30%

    A= T= 20%

9) Cytoplasm: Intracellular fluid and organelles

10) Centriole: Involved in mitosis.

Explanation:

A cell is simply defined as the structural and functional unit of an organism. It is made up of highly organized physical structures called intracellular organelles. These organelles includes:

• Ribosome

• Lysosomes

• Smooth Endoplasmic reticulum

• Plasma membrane

A type of cellular motion called ciliary movement, is a whip-like movement of CILIA on the surface of cells takes place in the respiratory airways of human.

The cytoplasm is filled with both intracellular fluid and organelles while the cytosol contains mainly dissolved proteins, electrolyte and glucose ( intracellular fluid).
