Answer : The mass of calcium in sample B is, 0.310 grams.

Explanation :

Law of definite proportion : It is defined as a given compound always contains exactly the same proportion of elements by weight.

Now we have to calculate the mass of calcium in sample B.

As, first sample of 0.146 g of fluorine = second sample of 0.294 g of fluorine

So, first sample of 0.154 g of calcium = second sample of \frac{0.154}{0.146}\times 0.294=0.310g of calcium

Therefore, the mass of calcium in sample B is, 0.310 grams.

This is called adaptation. An example would be a polar bear with white fur. They have this to be more efficent hunters, as they use it as a type of camouflage in order to sneak up on prey. Brown bear use this in the same way but their environment requires them to be brown in order to blend in beter with trees. So basicly adaptation

Explain why photosynthesis is much slower in underwater plants.
Viktor [21]

Answer:

Gases such as carbon dioxide diffuse much more slowly in water than in air. Plants that are fully submerged have greater difficulty obtaining the carbon dioxide they need. To help ameliorate this problem, underwater leaves lack a waxy coating because carbon dioxide is easier to absorb without this layer.
