‘Linked genes’ is a term used for two characters, whose genes are situated on the same chromosome. You are asked to investigate whether two characters of pea plants, are linked or not. The two characters are flower color and pollen shape. The dominant traits are purple flowers and long pollen grains. The recessive traits are white flower color and round pollen grains. You have true breeding strains available, and a garden. Which crosses do you make and how do you determine whether the genes for flower color and pollen shape are linked, or not? Provide enough detail so we can assess your understanding, e. g. draw Punnett squares and provide expected ratios of offspring for each cross.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

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.
