The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>

Advantages of Dry Heat sterilization
Reliable, nontoxic.
Low cost and is easy to install.
As the instrument remains dry after sterilization, there are no chances of corrosion.

Answer:
The freshwater biome is defined as the biome that comprises the water bodies such as lake, pond, rivers and wetlands and where the concentration of salt is almost less than 1%. It occupies near about 20-25% of the total earth's surface.
Generally, the characteristics of the photic zone of a freshwater biome include-
- It forms the upper layer of the freshwater body, ranging from the surface of the water up to a certain depth.
- It is the layer where the sunlight can easily penetrate.
- The photosynthesis process is driven out extensively by the aquatic plants existing in this layer.
- The primary producers are present in this zone that provides the food to almost all the freshwater organisms.
- In this zone, the rate of respiration is equal to the rate of photosynthesis.
All controlled experiments would have only one variable. If there were more than one variable the outcome of your experiment could be for multiple reasons and thus you would not be able to test whether your specific hypothesis was valid.
