Answer: Lk for this plasmid = 47
Explanation:
The formula to compute Lk is given by :-
Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)
Given: A plasmid 41 twists and 6 right handed writhes.
i.e. Twist (Tw) = 41 , Writhe (Wr) = 6
Then, Topological Linking Number (Lk) for this plasmid : = 41+6
= 47
Hence, the Lk for this plasmid = 47
Rainwater can replace or replenish freshwater sources.
Precipitation, such as rainwater, is the source of freshwater on Earth.
When the amount of surface freshwater increases, so does the amount of groundwater.
Human activity, such as taking a bath, may change the quality of a freshwater resource. :)
Shortness of breath is very common in the last trimester of pregnancy. This is because, the baby inside the uterus is growing and it starts to push the uterus that compresses the lungs above the diaphragm. This, leads to restricted expansion of the lungs while breathing and causes shortness of breath. Another reason for shortness of breath can be due to low iron content in the body.
If a pregnant woman in her last trimester reports occasional shortness of breath, the nurse should instruct her to:

3. practicing good posture and standing straight
4. relax as much as possible

Answer:
Cell
Explanation:
Cell the essential membrane- bound unit that contains the key particles of life and of which every living thing are formed.
These cells collaborate with other specific cells and become the structure squares of huge multi cell living beings, for example, people and different creatures.
The levels of organization range from a single organelle all the way up to a highly structured hierarchy.cell governs all physical and chemical process in life.
