How is the variation in color and markings beneficial to the orchid plant?
masha68 [24]

The variation in color and markings is beneficial to the orchid plants because it helps the flowers pollinate efficiently (Option C). It is an adaptation.

<h3>What is an adaptation?</h3>

An adaptation is an evolutionary trait that allows an organism to take advantage of survival and/or reproduction.

Orchid color can attract pollinators by mimicking flowers of plant species that live in the same area.

It is an adaptation known as mimetism, which allows them to take an evolutionary advantage.

For taking bath, water at 40⁰C is required. Calculate the mass of cold water at 15⁰C which is to be added in 60 Kg water at 100⁰
MrRa [10]

Answer:

Energy added to cold water, E1

E1 = m•Cp•ΔT = 6 x 4.187x(42-20) = 6x4.187x22

Energy lost by hot water, E2:

E2 = X(CpΔT) = X x 4.187 x (75-42) =X x 4.187 x 33

So, since E1 = E2

6x4.187x22 = X x 4.187 x 33

X = 6x22/33 = 4.0kg

So the mass of the hot water added to the 6kg of cold water is 4.0kg

if i had an 87.29% grade in a class because i turned in an assignment late and i got 5 out of 10 on that assignment, what would
mrs_skeptik [129]
It depends on how many points out of how many points you had to get the 87.29%

But I think your grade is a B....

89.95% and up = A
79.95% to 89.94% = B
69.95% to 79.94% = C

so yeah
