Answer:

The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split

¿Pueden dos terremotos de igual magnitud provocar daños muy diferentes? ¿Cómo?
nignag [31]

Answer:

Un terremoto con la misma magnitud y profundidad podría causar daños drásticamente diferentes dependiendo de la vulnerabilidad de la exposición. Por ejemplo, un terremoto M6 en California o Japón podría causar muy poco daño debido a las estrictas disposiciones sísmicas de los códigos de construcción. Mientras se encuentre en un país del tercer mundo, el daño podría ser catastrófico y se podrían perder millones de vidas.

How does the water cycle purify water
dimulka [17.4K]

During the water cycle some of the water in the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.

Can someone please help with this and explain! I will mark brainliest!!!
emmasim [6.3K]

Answer:

D       Flow of protons across an electrochemical gradient

Explanation:

The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.

In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.

The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.

Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.

Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
