Im pretty sure A Nor’easter is a strong wind or storm blowing from the northeast. Hope this helps
For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
Explanation:
I’m pretty sure the answer would be C
Since the mitochondria is the power house and the chloroplast is where photosynthesis takes place
Answer and explanation:
Cystic fibrosis occurs due to mutations in the CFTR gene, causing deficient ion transport in patients through cell membranes with a reduction in the amount of water from bronchial secretion.
This decrease makes the secretion more adherent to the bronchial walls and compromises the cleaning of these channels, facilitating pulmonary infections.
The disease also causes the blockage of the pancreas ducts, reducing the arrival of digestive enzymes in the intestines.
For an individual to develop cystic fibrosis by mutations, it is necessary to have both chromosomes 7 with the mutated CFTR gene. This means that a person needs to inherit mutated chromosome 7 from his mother and father.
