Think about the animals in an arctic ecosystem. How would those animals adapt over time if global temperatures rise over the nex
brilliants [131]

Given the fact that we are seeing a rise in the temperature of the globe, the artic animals in that ecosystem must adapt by a reduction in the rate of metabolism.

<h3>What is global warming?</h3>

Several evidences continue to emerge that the temperature of the earth have continued to increase and this is largely due to the fact that since the turn of the twentieth century and the rise of industrialization, there have been a rise in the emission of the carbon dioxide and other green house gases into the environment. As a result of this, the temperature of the earth has continued to rise steadily leading to the melting of the ice cover and the destruction of ecosystems that are found around the artic regions of the earth.

Now, we know that an organism is able to adapt to the changes that occur in its habitat by being able to alter some of its structure and function.

Given that the organisms that live in the artic are adapted to cold regions and low temperatures, the metabolic rate of the organisms is high in order to produce heat.

As a result of the rise in global temperatures, the organisms would have to reduce their rate of metabolism.

Butyric acid has a density of 0.959 g/mL at 20∘C. How many moles of butyric acid are contained in 1.56 mL of butyric acid?
lara [203]

Answer:

We have 0.0170 moles of butyric acid

Explanation:

Step 1: Data given

Density of butyric acid = 0.959 g/mL

Temperature = 20.0°C

Volume = 1.56 mL = 0.00156 L

Step 2: Calculate mass

Density = mass / volume

mass = density * volume

Mass = 0.959 g/mL * 1.56 mL

Mass = 1.496 grams

Step 3: Calculate Number of moles

Number of moles = mass / molar mass

Number of moles = 1.496 grams / 88.11 g/mol

Number of moles = 0.0170 moles

We have 0.0170 moles of butyric acid
