Ans.
HD (Huntington's disease) is a genetic neurological disorder that occurs due to damage and death of brain cells. it is caused by an autosomal dominant mutation in HTT (huntingtin) gene, having a trinucleotide repeat section that makes HTT protein.
The mutation leads to an increase in this nucleotide repeat count, associated with formation of altered or mutated huntingtin protein. These altered proteins show deleterious affect on brain cells and result in Huntington's disease.
Thus, the correct answer is 'option A). a mutated gene.'
Energy is stored in the chemical bonds.
The features or characteristics of organic compounds include:
1. They contain covalent bonds and are mostly non polar in nature
2. Have lower boiling and melting points than inorganic compounds
3. Many organic compounds are thermally unstable, They decompose into simpler molecules when heated at fairly high temperatures
4. Most organic compounds are inflammable and burn exothermically in sufficient air to yield carbon dioxide, water and heat energy.
5. Most organic compounds being largely non polar are insoluble in water.
Answer:
I believe the answer is C.
Explanation:
This is because the basketball is the bigger object here so that should represent something bigger like the solar system. Then the tennis ball would represent earth because it is the smaller object here.
