Circulatory system
The circulatory system is the transport system for endocrine information. While the nervous system uses neurons, the endocrine chemicals and hormones must circulate through the body via blood vessels. Many glands in your body secrete hormones into the blood.
RFLP, AmpFLP are the two techniques which is used to create DNA profile
Explanation:
<u>RFLP technique: </u> RFLP technique stands for “Restriction Fragment Length Polymorphism”. It is molecular method of genetic analysis which allows to identified based unique pattern of restriction enzyme where DNA is cutting in specific regions. It requires large amount of sample. The costing is very high
<u>AmpFLP: </u>The AmpFLP stands for amplified length polymorphism. It is PCR based tool. Firstly, it uses as restricted enzyme. It is cheaper than RFLP technique. It is used as genetic engineering
Answer:
to test for liberation of O₂ in the light.
Explanation:
Minerals are naturally-formed substances that have a specific chemical properties: abiogenic (minerals are not produced by or derived from living organisms, non-organic in origin), stable at room temperature (i.e. at 25 degrees C)
, are represented by a known chemical formula
, have an ordered atomic arrangement/structure. Coal is not classified as a mineral because it is an organic substance. Correct answer: D (coal is formed from the remains of dead plants and animals).
