Based on the hypothesis (Big Bang theory) that the universe is expanding, an analysis of light wave would indicate: A. a decrease in frequency and a red shift.

<h3>What is a redshift?</h3>

A redshift can be defined as a displacement (shift) of the spectral lines of an astronomical (celestial) object toward longer wavelengths and a corresponding decrease in frequency, as a result of the Doppler effect.

Basically, a redshift occur when observing an astronomical (celestial) object from planet Earth because it's receding (moving away) from planet Earth.

In conclusion, we can infer and logically deduce that an analysis of light wave would indicate a decrease in frequency and a red shift based on the hypothesis (Big Bang theory) that the universe is expanding.

Contrast the electron transport chain in photosynthesis with the one in cellular respiration by identifying sources of the high-
nlexa [21]

Respiration:

The respiratory chain detailed here is that of mammalian mitochondria:

NADH → NADH dehydrogenase → ubiquinone (coenzyme Q10) → coenzyme Q-cytochrome c reductase → cytochrome c → cytochrome c oxidase → O2;

succinate → succinate dehydrogenase → ubiquinone (coenzyme Q10) → coenzyme Q-cytochrome c reductase → cytochrome c → cytochrome c oxidase → O2.

It consists of the following elements:

The high transfer potential electrons of NADH are transmitted to coenzyme Q10 (ubiquinone) by NADH dehydrogenase, or complex I. Reduced coenzyme Q10 is ubiquinol Q10H2.

The electrons with a high succinate transfer potential are transferred to coenzyme Q10 by succinate dehydrogenase, or coenzyme II, also giving ubiquinol Q10H2.

Ubiquinol Q10H2 transfers its electrons to two cytochromes c under the action of coenzyme Q-cytochrome c reductase, or complex III.

Four cytochromes c each transfer their electron to an oxygen molecule under the action of cytochrome c oxidase, or complex IV. Two molecules of water are formed.

Each of these four respiratory complexes has an extremely complex structure partially included in the internal mitochondrial membrane. Apart from the complex II, they are proton pumps. The electrons circulate between these structures on liposoluble or hydrophilic electron transporters depending on the case.

Photosynthesis:

Photophosphorylation is the equivalent, for photosynthesis, of oxidative phosphorylation for cellular respiration. It constitutes the "light phase" of photosynthesis, that is, it groups together light-dependent reactions.

In plants, photophosphorylation occurs in the membrane of thylakoids, within chloroplasts:

H2O → photosystem II (P680) → plastoquinone → cytochrome b6f complex → plastocyanine → photosystem I (P700) → ferredoxin → ferredoxin-NADP + reductase → NADP +;

cyclic photophosphorylation: (ferredoxin →) plastoquinone → cytochrome b6f complex → plastocyanine → photosystem I (P700) → ferredoxin (→ plastoquinone).

Contrast:

<u>What he has in common is:</u>

*The sequence of several complex membrane proteins transporting electrons.

*The conversion of DNA into ATP.

<u>The differences</u> are in the transport proteins themselves, as well as the direction of H + flux (to the cytoplasm for photosynthesis, and to the mitochondrial matrix in respiration).

The different ways pulse rate can be used to measure fitness?
Stels [109]
A normal heart rate ranges between 60-100 beats per minute. The higher the heart rate is, the faster the blood is pumping through the heart. When exercising a persons heart will be higher because the brain and the muscles in the body are in need of oxygen so the heart needs to pump faster in order to sustain optimal performance.<span />

When a vegetable is placed in very salty water, the vegetable becomes soft and collapses. why does this happen?
Gala2k [10]
The answer is B, because salt water has lots salt, and little water. The cells lose their water content and fill up with salt, causing ti to collapse.
