Hemoglobin is a protein found in vertebrate blood. Human and chimpanzees have the same sequence of amino acids in their
hemoglobin. Humans and monkeys have 96% similarity in their
hemoglobin sequences. From this information a biologist can conclude
that
O monkeys and chimpanzees are more closely related than humans and
chimpanzees.
O humans and chimpanzees shared a common ancestor more recently than
humans and monkeys.
O humans and chimpanzees shared a common ancestor with monkeys more
recently than with each other.
O hemoglobin is important for primates.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.

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.

"it built up in the atmosphere"

i think thats it, idk, i tried looking for this exact q& a for grad. and idk if i got this question right or sorry if im wrong
