Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.
<h3>What affects the speeds at which these objects fall?</h3>
- The falling speeds in both air and a vacuum will be the same for both objects.
- This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
- The same will occur in water if and only if the densities of the two objects are equal.
Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.

Decomposers also break down the bodies of dead organisms resulting in nitrogen being returned to the soil as ammonia. In some conditions denitrifying bacteria in the soil break down nitrates and return nitrogen to the air.

Answer:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric <u><em>carbon dioxide</em></u> (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
A- if her results support her hypothesis
