Lipids don't dissolve in water because of the different polarities. Water is polar and lipids are not polar which is why they don't dissolve. What this means is that they don't bond and don't share electrons and therefore don't mix.
Answer:
E
Explanation:
Phytochrome is an important pigment that regulates photomorphogenic aspects of plant growth and development such as seed germination, stem elongation, leaf expansion, formation of certain pigments, chloroplast development and flowering.
Phytochrome has two different chemical structures that are inter-convertible. The forms are named by the color of light they absorb maximally: Pr is a blue form that absorbs red light strongly (660nm) and Pfr is a blue-collar form that absorbs far-red light strongly (730nm). When each phytochrome form absorbs its respective photon, they change chemically into their complementary form.
N.B: In plants, Pfr is the physiologically active or signalling state.
In the dark, phytochrome is in the Pr (inactive) form because at night, Pfr slowly converts back to Pr (inactive form).
The biologically inactive form of phytochrome (Pr) is converted to the biologically active form (Pfr) under illumination with red light. Far-red light and darkness converts the molecule (Pfr) back to the inactive form. Although, it converts back to Pr, slowly in darkness
A Fourier analysis is a technique that is able to determine both the amplitude spectrum and the phase <span>spectrum of any signal</span>. This analysis is based on the finding that all sound waves can be derived by adding sinusoids together (so long as the sinusoids are of the appropriate frequencies, amplitudes, and phases).
Answer:
sound waves. they come in longitudinal waves and vibrations. echo is wrong though youre right on that one
The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood in the Circulatory System is needed throughout the body so that other systems work properly. Like for instance the Nervous System has the brain, and the brain needs blood to function.
