The best improvement to these instructions that Keisha can make
immediately and easily is to describe where the instructions start from.
Does the route start from Keisha's house? From her friend's house?
From my house ?
Knowledge of the coordinate reference frame makes a big difference,
and it's essential.
Uniformitarianism(1785)
Relative dating(around the 1800’s)
Absolute dating also known as radiometric dating (1905)

Prostatic acid phosphatase was purified from prostatic fluid. Monospecific antisera to the purified acid phosphatase was then produced in rabbits. When antibody was coupled with acid phosphatase, the enzymatic activity was markedly stabilized against pH and temperature degradation. Both acid phosphatase and rabbit anti acid phosphatase were non specifically coupled to Sepharose-4B using cyanogen bromide. Under these circumstances slight stability occurred when antibody was bound to Sepharose, and then acid phosphatase added to the gel antibody complex. When acid phosphatase was complexed to Sepharose, no stabilization occurred.
Answer:
definition with benefit is given below of
1st. gravitropism
2nd. phototropism
3rd. thigmotropism
4th. photoperiod
Explanation:
1st is gravitropism
gravitropism is process in which plant grow in the direction that gravity act
It is also called geotropism
and
Gravitropism is important for plants because it directs the roots to grow in the downward direction that is important for obtaining nutrients
2nd is phototropism
phototropism is the process in which plant growth directed by the light
and
we know plants need light to carry out photosynthesis
so Phototropism direct the growth of the stem and branch toward sunlight
3rd is thigmotropism
thigmotropism is the directional change in growth of plant in response to a touch stimulus
and
thigmotropism is especially important for climbing plant that is use support to climb up
4th is photoperiod
photoperiod is the physiological change in organism in the response to length of the day and night
and
it play important role to determining the physiological developmental process in the plant such as budding and tuberization
