Yes. You could do this by adding solvents to break down any cell walls, centrifuge to separate the DNA, if you haven't got much then upscale with PCR, gel electrophoresis could be used to detect the DNA, and Sanger sequencing to find the sequence.

Hormones are chemicals made in the soil that affect parts of plants.<br> a. True<br> b. False
vampirchik [111]

Hormones are chemicals made in the soil that affect parts of plants. The statement is false.

<h3>How are gibberellins able to affect other parts of the plant?</h3>

Gibberellins stimulate the growth of shoots which increase the biomass and vegetative growth of plants. If vegetative growth increases, the root biomass is also increases.

So we can conclude that other parts of the plant are also affected due to gibberellin because it stimulates the growth of shoots which is the upper portion of the plant.

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis a
goldfiish [28.3K]

Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.

What is the electron transport chain's source of energy?

The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.

In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.

Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.
