Answer:
The correct answer is reciprocity or pairing of the bases.
Explanation:
The fact that bases are reciprocal to one another (thymine and adenine, cytosine and guanine) means that the same information contained in one strand is also found in the other one. This led to the fact that the DNA molecule is the one that carries genetic information.
Answer:
The Earth is at the center
Explanation:
Aristotle was the first to believe the earth was round but he still thought everything revolved around the earth.
The label A represents mitochondria.
The mitochondria is also called the powerhouse of the cell which converts glucose to energy rich molecules of ATP.
Label B represents nucleus.
Nucleus contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.
Label C represents lysosome.
Lysosomes contain digestive juices which breaks down large cell parts and large molecules and helps in intracellular digestion.
Label D represents rough endoplasmic reticulum having ribosomes.
The rough endoplasmic reticulum provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
As this procedure is carried out in the natural habitats of this species, this is an <em>in-situ conservation</em>.
<em>In-situ conservation </em>is the type of conservation that occurs on site, where the natural populations of plants or animals are found.
