Answer: The estimated size of the population is 150
Explanation: For the Mark-Recapture method, there is a formula that can be used:
N = (M × C)/R
where :
N = estimated number of individuals in the population
M = number of individuals captured and arked
C = total number captured the second time (with and without a mark)
R= number of individuals ecaptured (those with a mark)
So with this formula we can calculate an estimation of the population of rodents. Because there is no number of rodents captured the second time given, we will assume 30 was caught again, making the 20% found marked being 6. We calculate it as:
N = (M × C)/R
:N = ( 30 × 30)/ 6
:N = 900/6
:N = 150 estimated rodents in the population
Answer:
Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.

This might have an evolutionary advantage as to why the egg behaves such. Presumably, this can help the yolk develop leaving it away from any inconvenient circumstance

The answer to this question would be: <span>vestibular
Vestibular is an organ that was located in the ear that was responsible for balance function. In the vestibular organ, there are 3 circle like parts that each will be responsible for a dimension. The circle is was filled with fluid and the fluid will move if the head is accelerating.The interaction of these 3 circle makes the human head can detect rotation in 3 dimensions. </span>
