The right answer is Electromagnetic waves can transfer energy through empty space.
Electromagnetic radiation refers to a form of linear energy transfer. Visible light is electromagnetic radiation, but is only a small slice of the broad electromagnetic spectrum. The propagation of this radiation does not need material to move.
if we take the example of solar energy, it spreads in space, the atmosphere until reaching the earth.
Once it reaches a material, it gives rise to many phenomena such as attenuation, absorption, diffraction and refraction, redshift, interferences, echoes, electromagnetic parasites and biological effects.
Answer:
Repair mechanism for base cleavage (BER)
Explanation:
Repair by base cleavage (BER)
The altered bases are specifically recognized by glycosylases and removed, generating an AP site. The hole is filled by a DNA polymerase that takes the healthy strand as a template. This system arises not only by exposure to external agents, but also by the cell's own activity.
In case of damage in more than one nucleotide, repair by nucleotide excision (NER) is performed.
Nucleotide excision repair (NER)
The damaged area is recognized by UvrA and B, then A and B separate and UvrC enters which forms a complex with endonuclease activity with B. This enzyme cuts the T-dimer and the gap is filled by a DNA polymerase. There is also the TC-NER system (transcription-coupled nucleotide repair system). The alteration of these mechanisms gives rise to diseases such as: Xeroderma pigmentosum, Trichotiodystrophy or Cockayne Syndrome
The correct answer is: In both systems, ATP is produced by chemiosmosis.
Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).
Answer:
Autumnal equinox right ascension = 12 hours; declination = 0°; Sun rises at 90° azimuth and sets at 270° azimuth. December solstice right ascension = 18 hours; declination = -23.5° Sun rises at greater than 90° azimuth and sets at less than 270° azimuth.
Explanation:
Waves and tides are the rise and fall of ocean water
