We have done a nutrient recovery experiment for Hec and Trp. Below are the growth results of plating nine colonies on plates containing different media compositions.

MINIMAL MEDIA: 1, 3, 5, 8
+Hec: 1, 3, 4, 5, 7, 8
+Trp: 1, 2, 3, 5, 8, 9
+Hec +Trp: 1, 2, 3, 4, 5, 6, 7, 8, 9

Indicate which colonies have a loss of function mutation for the given genotypes. When filling in the blank, use the colony numbers in numerical order separated by commas only. No spaces. For example in the box enter: 1,2,6,10

which are post-impressionist paintings? check all that apply?

explanation:

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and color.

hope this have a good day

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
