Answer:

The changes I observed in the moth populations result from the best-hidden moths surviving and reproducing, passing on their colors to their offspring. Why? Because individuals NEVER evolve, populations do. The second option fits best with Darwin's theory of natural selection, in which he stated that individuals with the most favorable traits are the ones to survive and reproduce, thus passing their traits onto the future population. The first choice incorrectly believes in Lamarck's theory of evolution in which he incorrectly believed that individual organisms in the population developed a trait that would help them survive (e.g. longer necks in giraffes).

You conduct a mark-recapture survey of eastern fence lizards (Sceloporus undulates) in a 2-hectare plot in eastern Arizona. You

Ksenya-84 [330]

Answer:

Option C

Explanation:

Given -

Total number of initially marked lizards (M) $= 250$

Total number of recaptured lizards (C) $= 75$

Total number of recaptured marked lizards (R) $= 24$

As we know that -

$\frac{M}{N} = \frac{R}{C}$

We have to find "N" . "N" is the total population size of lizards in a 2-hectare plot in eastern Arizona.

Thus, on rearranging the above equation, we get -

$N = \frac{M * C}{R}$

Substituting the given values in above equation, we get -

$N = \frac{250 * 75}{24} \\N = 781.25\\N = 781.3$

Hence, option C is correct

How many ATP are generated in the electron transport chain? оооо 2 4 32 36

Svetllana [295]

Answer:

32 ATP molecules are generated in the electron transport chain.

Explanation:

The cell used a process known as Chemiosmosis and to produce ATP. The energy released from the electrons during the electron transport system and they pump the protons. The energy is transferred into higher energy bond of ATP and they are made to perform their cell work.

'Electrons are the subatomic particles that orbit the nucleus of an atom'. They are always negative in charge and are always smaller than the 'nucleus of the atom'. The electron transporters are arranged in series and they are embedded into their inner mitochondrial membrane and they are shuttles the electrons from ' $\mathrm{NADH}^{\prime}$ and ' $\mathrm{FADH}_{2}$ ' to the molecular oxygen. In this process, the protons are pumped through the 'mitochondrial matrix' to 'the intermembrane space' and the oxygen level is lowered to form the water.
