<span>The finches that Darwin studied in the Galapagos islands have evolved with different types of beaks: drilling, cracking, tearing, and fishing. This is an example of B. adaptive radiation.
These birds have adapted to their environment - they needed to drill, crack plants, fish, etc. so their beaks have changed and adapted so as to fulfill those needs.
Predation is used for hunting smaller animals, warning coloration refers to a change of color, and protective resemblance refers to an animal blending with its surroundings.

Answer:

The answer is B) Adaptive Radiation

Explanation:

This is an example of adaptive radiation, because adaptive radiation describes the rapid speciation of a single or a few species to fill many ecological niches.

Answer:

Number of moles of photons required = 5.04 × 10⁴ moles

Explanation:

The energy of a photon can be calculated from Planck's equation E = hc/λ

Where h = 6.63 × 10-³⁴ Js and c, the velocity of light = 3.0 × 10⁸ m/s

Energy of one mole of photons = N₀ × hc/λ

wavelength of photon, λ = 520 nm = 5.20 × 10-⁷ m

Energy of one mole of photons = 6.02 × 10²³ × 6.63 × 10−³⁴ × 3 × 10⁸/5.20 × 10-⁷

Energy of one mole of photons = 2.30 × 10⁵ J/mol

Energy required to raise the temperature of a given mass of a substance, E = mcΔT

Where m is mass of substance,  c is specific heat capacity,  ΔT is temperature difference

Mass ofnwternin the pool = volume × density

Volume of water = Volume of swimming pool

Volume of water = 16 × 34 × 6 ft³ = 3264 ft³

1 ft³ = 28316.8 cm³; 3264 ft³ = 28316.8 × 3264 = 92426035.2 cm³

Density of water = 1 g/cm³

Mass of water = 92426035.2 cm³ × 1 g/cm³ = 92426035.2g

ΔT = 80°C - 50°C = 30°C, c = 4.18 J/g/K

Energy required to raise 92426035.2 g water by 30° C = 92426035.2 × 4.18 × 30

Energy required = 1.16 × 10¹⁰ J

Hence, number of moles of photons required = 1.16 × 10¹⁰ J/2.30 × 10⁵ J/mol

Number of moles of photons required = 5.04 × 10⁴ moles

How does density relate to the cold and warm air masses?
Amanda [17]
Warmer  air   is   less  dense  than  cold air.As  air  warm  it  rises  while  the  cold  air  sink. Warmer  air  masses forces the  cooler  air to  move  which  causes  wind.  These  is  illustrated  when  you  open  a hot oven the  hotter  air  inside  the  oven  rises  into  cooler  air  outside  the  oven.

Option B

Primary productivity is not limited by time

<u>Explanation:</u>

To ecosystems, the productivity of the primary producers is essential because certain bodies generate energy for different existence bodies. Besides the era, primary production ends in the extension of dissimilar plant biomass to the practice. Consumers acquire their strength from primary producers, unless directly (herbivores, any detritivores), or diffusely.

It depends superimposed on the availability of the sunlight, availability of the nutrients such as nitrogen, iron, phosphorus from the soil and water. The primary productivity of the plant's distinct autotrophs is not restricted by time.
