Which conclusions are correct from the thin-layer chromatography of the inks?

Biology

Dennis_Churaev [7]3 years ago
8 0

Based on the result in this experiment, the mobile phase rose up on the TLC plate then dragged the ink from the marked dot up along the TLC plate, which is the light pink pigment whose Rf was 0.98 had the greatest affinity to the mobile phase. Moreover, the pigment that was closer to the marked dot was more attracted to the stationary phase, which is the dark pink spot that had an Rf of 0.72 and had a greater affinity to the stationary phase.

A performer, seated on a trapeze, is swinging back and forth with a period of 8.90 s. If she stands up, thus raising the center
iren2701 [21]

Answer:

8.800s

Explanation:

When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.

First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation

T = 2π×√(Lo/g)..... (1)

Let's make Lo the subject of the formulae

Lo = gTo^2/4π^2 ..... (2)

Let's put our values into equation (2) to get Lo

Lo = gTo^2/4π^2

= (9.8m/s^2)(8.90s)^2

------------------------------

4π^2

= 19.663m

Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be

L = Lo - (0.44m)

= 19.663m - 0.44m

= 19.223m

Now let use the value of L into equation (1) to get the period T after raising

T = 2π×√(L/g)

= 2π×√(19.223m/9.8m/s^2)

= 8.800s

Two pink-flowering plants are crossed. The offspring flower as follows: 25% red, 25% white, and 50% pink. What pattern of inheri
zloy xaker [14]

Answer:

Co-dominance

Explanation:

Considering the allele for red pigment as C<em>R</em> and that for a white pigment C<em>W</em>, a pink flower will equally express both the pigments in its phenotype and will thus have a genotype of C<em>R</em> C<em>W</em>.

Crossing CR CW × CR CW you'll get,

25% C<em>R</em> C<em>R</em> - red flowers

50% C<em>R</em> C<em>W</em> - pink flowers

25% C<em>W</em> C<em>W</em> - white flowers
