The stage that scientists begin to ask questions and attempt to explain observations is A. forming hypotheses. This is because a hypothesis is basically a testable question about observations scientists make.
Explanation:
The use of CRISPR/Cas9 avoids the need for protein engineering to develop a site-specific nuclease against a specific DNA target sequence, requiring only the synthesis of a new piece of RNA. This dramatically simplifies and greatly reduces the time needed for gene editing design and implementation.
Answer:
Option A. magnitude
Explanation:
Electric field is the area around the electric current where its effect is observed. If the lines of electric field are close to each other, it means electric field is stronger and if the lines are far away from each other so it indicates that the electric field is weak. There is inverse relationship between electric field and distance from the charge. If the distance is higher, so the electric field is weak and vice versa.
Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.
Lotions, body cream, oils
