I believe it is false...........
<span>mtDNA analysis is the best DNA technology to use. In DNA fingerprinting scientists run a gel electrophoresis of the subject's DNA in order to establish the banding patterns of the DNA fragments. People will always share half of their DNA with a parent. SO half of an individual's banding pattern will match half of their parent's DNA banding pattern. If someone is missing is found then scientists can compare the DNA fingerprint or banding patterns to see what the likelihood is of them being related.</span>
Answer:
i) Rusting occurs the least in tubes 2 and 3 because either of air and water which are necessary for rusting is absent in the two tubes respectively.
ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.
Explanation:
Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.
For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.
In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.
In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.
In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.
In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.
Because chromosome X carries these genes which lead To catch these diseases.
males catch these disease more than females because they have 1. chromosome X but females has 2 .
so the Recessive trait appear in males more than females .
These are the thykloid and the stroma
