Which statement is one of fact supporting how pH and flower color are related?
Goshia [24]
Yes, pH of the soil affects the colour of flower.

Flowering plants grown in acidic soil (pH<7) bears blue flowers or at has a blueish tint.

Whereas, Flowering plants grown in Neutral (pH=7) and Basic (pH>7) soil bears pink and red flowers.

A plant's flower color is determined by a complex balance between chlorophyll, beta carotene, flavonoids,etc in particular pH of the soil to give out vibrant colors like red, blue, pink, yellow,etc.

Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e
cricket20 [7]

Answer:

  • The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
  • According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
  • After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.

stealth61 [152]

The area residing in the center explains the bilatial tibulti, which precedents the bratuluti tubilitu. As for the rack itself, it has a half-moon (in laymens terms) axial, which appendages smoothly in all transition. The answer would certainty relate less to moving and a part itself, and more towards coordination or other terms (for which there are many), as this question is quite subjective.

In short, it has nearly free half-moon movement, though blocked in transition by its own quartsor axial.

Michelle and George are studying the forces and motion of a 0.8-kg low friction cart on a horizontal table. They use a spring sc
Helen [10]
Table 1: The horizontal pulling forces (F) and resulting acceleration (a) for the cart.



The cart experiences no motion when there is 0.1 N of horizontal force, so F=0 in this case. When one uses Newton's Second Law to find the acceleration caused by each force, it becomes clear that every row in the chart represents a horizontal force of approximately F=20 N. The best fit for the missing value is F=-30N.

If a cell contains 95% water and is put into a beaker with 100% water, what will happen
Kisachek [45]

Answer: The quantity of water in the beaker will reduce. The cell will increase size.

Explanation: There is difference in water concentration between the cell and the beaker, therefore water will move from the beaker into the cell causing the cell to expand and the quantity of water in the beaker to decrease. There will be movement of water molecules from an area of high water concentration (beaker) to an area of low water concentration (the cell) through a selectively permeable cell membrane. The aim of this is to create an equilibrium between the water concentration in the cell and that in the beaker.
