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.
Each moon or planet matched to the most accurate characteristic;
1. It contains large amounts of frozen water - C. Europa
2. High levels of carbon dioxide increase the temperature of its atmosphere - B. Venus
3. It does not have enough gravity to have an atmosphere - A. Earth's moon
4. Astronomers believe there is a good chance it contains liquid water - D. Mars
Europa is the smallest of the four Galilean moons of Jupiter. Others are Io, Ganymede, and Callisto. An outer layer of water, about 100 km (62 mi) thick, covered the surface of Europa. A part of the outer layer (crust) is said to be frozen, while the other part is a liquid ocean below the ice.
Venus is the second planet from the Sun and the hottest planet in the solar system. The atmosphere of Venus is dense, and it is composed mainly of carbon dioxide (roughly 96.5 percent), which traps heat and causes a greenhouse effect.
Ribosomes and Endoplasmic Reticulum. Ribosomes are the organelles responsible for protein translation and are composed of ribosomal RNA. So, the answer has to be A and C.
Answer:
Temporal partitioning or niche differentiation
Explanation:
Temporal partitioning refers to the variability in the competitive abilities of different species competing for the same resources based on varying conditions of the environment.
The environmental factors could be light, temperature, moisture, etc. Each species specializes in feeding within varied condition of one or more of the factors.
<em>In this case, both species are in competition but while the first species feeds during the day, the second species feeds during the night. Here, light and temperature probably plays a huge factor.</em>
Temporal partitioning is also known as niche differentiation, segregation, separation or niche partitioning.
