Explanation:
B is absolutely correct answer.
DNA testing utilized particular regions in our DNA that are unique to every individual. These regoins are tested using tehcnques such as RFLPs (Random Fragments Length polymorphisms), SNP (Single Nucleotide Polymorphism), STR (Short Tandem Repeats), Y chromosome (for males) and mitochondria DNA analysis (for females).
QUESTION:- The sun shinning on thr surface of a lake can heat up the air just above the water.What happens if this air gets warmer then the air above it?
ANSWER:- If the air gets warmer then the aur above it then the air will go above then the air above on it .
REASON :- It is a rule of wind that it flows from hidh density to low density.

Answer:
<h2>
The organelles are mitochondria and chloroplasts.</h2>
Explanation:
<em>The mitochondria and chloroplasts play a major role in energy conversion that helps to synthezise gene expression products. They were essential to the evolution of present day eukaryotes. These specialized structures are enclosed by double membranes, and they are believed to have originated back when all living thing on Earth were single-celled organisms. The proposed origin of mithocondria and chloroplasts is known as the endosymbiotic hypothesis.</em>
<em>The mithocondria is considered the powerhouses of the cell, it enables eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. Within the eukaryotic cells, mithocondria works like batteries, because they convert energy from one form to another.</em>
<em>The eukaryotic cells may contain several other types of organelles, such as the endoplasmic reticulum, the golgi apparatus and lysosomes. </em>
