The organs in the alimentary canal are important to digestion because they work together to move food and waste through the body. Without them, food wouldn't be able to move to their correct organs to digest and provide nutrients & energy, and waste would not be able to get out of the body.
Answer:
Accelerated erosion or change in cover tend to persist and grow over time because the continuous erosion of the channel further escalate the rate of erosion by further widening of the channel unless there is a human intervention to stop this. Once the vegetative cover of a soil is altered, it leaves room for erosion (the degree of the erosion depends on the degree of loss or gain of vegetative cover). In a bad case where there is a loss of vegetative covering of the soil, erosion sets in, washing away the top soil and reducing the cover vegetation even more. These two activities are those type of activities that grows over time once they are activated.
We have to answer based on basic concept on electron.
The correct answer is: Since electrons repel each other, electrons pairs will be as far apart as possible.
We know, electrons are negatively charged particles and negatively charged particles repel to each other.
When electrons which are of similar charge repel each other, they go far apart from each other..

Answer:
Q = -33.6kcal .
Explanation:
Hello there!
In this case, according to the equation for the calculation of the total heat of reaction when a fixed mass of a fuel like ethane is burnt, we can write:
Whereas n stands for the moles and the other term for the enthalpy of combustion. Thus, for the required total heat of reaction, we first compute the moles of ethane in 3 g as shown below:
Next, we understand that -337.0kcal is the heat released by the combustion of 1 mole of ethane, therefore, to compute Q, we proceed as follows:
Best regards!
