Answer:
See the answer below
Explanation:
a) The mode of inheritance of the bar mutant is X-linked and dominant.
Assuming that barness is represented by the allele B.
Bar female = 
or 
Wild type male = 
Bar female x wild type male:
x
All of the F1 flies are bar because a single B allele is required for the trait to be expressed.
Bar male x wildtype female
x 
All the female offspring are barred while all the males are wildtype barred resulting in a 50/50 (857/905 is approximately 50/50) ratio of barred/wildtype offspring.
b) Genotypes of each of the cross above, including the parents and the F1 generations.

Answer:
The correct answer will be-
1. Mobile elemests- LINEs and SINEs
2. Exons
3. Non-coding RNA genes
4. Introns
5. Repetitive DNA sequence
Explanation:
The human genome represents the total nucleic acids present in the Homo sapiens packaged in 23 chromosome pairs and contains 3 billion DNA base pairs.
The human genome comprises of protein-coding genes and non-protein-coding genes. The protein-coding sequence accounts for only a very small proportion that is 1.5% whereas the rest non-coding sequence accounts for 98.5%.
The non-coding sequence includes the Non-coding RNA genes( microRNA, small nuclear RNA), Introns which accounts for 26%, Repetitive DAN sequence (50%), mobile elements like LINEs and SINEs and exons.
Thus, Mobile elements- LINEs and SINEs, Exons, Non-coding RNA genes, Introns and Repetitive DNA sequence are the correct answers.
Hydropower involves blocking rivers, which disrupts ecosystems.
Explanation:
Prolonged use of hydropower can disrupt the ecosystem since it involves the blocking of rivers. This is a long term impact hydropower generation.
- Hydropower is a renewable source of energy in which water is used to generated electricity.
- The water is sourced from large river bodies with a lot of kinetic energy in them.
- Huge volumes of water discharge is needed for this process.
- Therefore, water must be dammed for this purpose.
- Damming of water bodies affects the ecosystem.

The correct options are:
The organism would not grow.
If an organism were cut or burned, the damaged area would not heal.
The organism would not produce new cells.
The mitosis is essential for the division of the cells. The division of the cells allow the organism to grow and heal the damaged cells. The division of the cells replace the old cells and multiply the number of the cells in an organism. hence, in any condition, the organism would be affected and in the absence of the mitosis, the organism cannot heal and cannot grow, due to non-production of new cells.
