mostly collagen and some calcium phosphate
Answer:
B. As the distance between loci increases, some multiple crossovers go undetected such that the relationship between recombination frequency and map distance ceases to be linear.
Explanation:
When calculating recombination frequencies, and hence, map distances, we might notice that these distances are not completely additive. They might vary. <em>For example, let us say that we have three genes, A, B, and C, in that order. </em>We calculated that the <em>distance between A and B equals 5.9</em> MU and that <em>B and C are 19.5 MU apart.</em> According to this, we might say that the <em>total distance between A and C is 25.4 MU (5.9 + 19.5). </em>However, after a<em> two-point calculation between A and C, the value equals 23.7 MU. </em>
The recombination frequency between these two genes located in the extremes and far apart underestimate the actual genetic distances between them because there might occur other crossing-overs that were not detected. This is <em>when calculating the distance between A and C, we probably will not detect the occurrence of a double recombinant between them, and hence, we might sub-estimate the real distance.</em>
The relationship between the actual map distance (number of crossing overs) and the recombination frequency between two loci, is not lineal. The farther apart are the two genes, the worse is the distance estimation.
Biochemical stress is another factor fire
Rarefaction in terms of ecology can be defined as a technique used to assess species richness from the results of sampling.
It allows the calculation of richness of a particular species for a given number of individual samples, and these are based on the construction of rarefaction curves.
Hence, the correct answer is: option A-Creating a representative sample
The correct answer is C. self-report inventory.
A self-report inventory test is a category of personality tests in which individuals answer a series of questions about personal behavior. Self -report inventory asks questions directly about their personal interest, values, symptoms and behaviors. it may takes five to fifteen minutes to complete test.
