Answer:
C. capillaries connect arteries and veins.
Explanation:
A is false, veins carry blood towards the heart.
B is false because arteries are the thickest blood vessel.
C is completely true
D is false, heartbeat is controlled by electric impulses
Yellow- Green Wavelength of light at peak absorption of 565nm.
Halobacterium is known to be a member of Archaea
and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis
with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin
and halorhodopsin as photosynthetic pigments.
However, photosensory pigements found in
Halabacterium were:
1. photosystem 565 which is used to respond to yellow
–green light in other for cell to find optimum conditions for ATP synthesis and
photophosphorylation and they have peak absorbtion at 565nm.
2. Photosystem 370 nm appears to be responsible
for the protective avoidance of blue/UV light.

Option A is the right answer
Answer:
B) FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2
Explanation:
FADH2 and NADH give their high energy electrons to the terminal electron acceptor molecular oxygen via an electron transport chain. As the electrons move through electron carriers of the electron transport chain, they lose their free energy. Part of the free energy of the electrons is used to pump the protons from the matrix into the intermembrane space. Therefore, part of the energy of electrons is temporarily stored in the form of a proton concentration gradient.
NADH gives its electrons to FMN of complex I while FADH2 gives its electrons to the Fe-S center of complex II. Both the complexes are oxidized by coenzyme (Q) which in turn reduces Fe-S centers of complex III. Cyt c of complex IV obtains electrons from complex III and passes them to CuA center, to heme "a" to heme "a3-CuB center" and finally to the molecular oxygen.
So, the compounds arranged with respect to the energy content of electrons in descending order are as follows: FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2.
