Biology
1 answer:
OLEGan [10]2 years ago
3 0

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

A larger population density always indicates a larger population size
oee [108]

Answer:

False

Explanation:

The population density and the population size can be correlated, but often can be very misleading. If a population size is large it doesn't mean that the population density is large, or if the population size is small it doesn't mean that the population density is low. We can take as examples the United States and Malta, where the United States have just over 327 million people, but a population density of 33.6 people per square km, while Malta has a population size of just over 493,000, but a population density of 1,457 people per square km.
