Answer:
1. Plants are green due to presence of green pigment chlorophyll in their chloroplasts.
2. ATP is used to make organic sugars (glucose)
Explanation:
Chlorophyll pigments absorb the light in the blue and red regions and reflect all the green light. When the reflected green light reaches our eyes, the plants look green in color. The color of the object is determined by the color of the reflected light.
Splitting of water during the light-dependent phase of photosynthesis and electron transfer through cytochrome b6/f complex generates the proton concentration gradient which in turn drives the synthesis of ATP. Calvin cycle refers to the set of reactions that fix the atmospheric CO2 into organic sugars such as glucose. The ATP molecules formed during light reactions are used to drive the endergonic reactions of the Calvin cycle.
Answer:
D
Explanation:
because it shows the features of a bird
The nucleolus is the central support structure
1) To calculate the population density you first need to know how many <span>squirrels form that population.
To calculate the number of</span><span> squirrels:
1500</span> squirrels is the capacity, so it's equivalent to 100%
So how much squirrels are present in 80% of the area:
1500----100 %
x----------80 %
x= 1200 <span>squirrels
</span>
2)Population Density equals the number of squirrels divided by the land area
In the first part was calculated the number of squirrels and the exercise gives us the area in hectares so the only thing left to do is divide them.
(since this exercise doesn't specify that the area needs to be in a certain measurement we can use hectares)
Population Density = 1200/ 150
<span>The population density of the squirrels is 8 per hectare</span>
Answer:
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
