Can you show the picture of the question please?
Answer:
A red blood cell, sitting in the right atria of the heart is chocolate-brown in color since its a deoxygenated red blood cell with carbon dioxide rather than oxygen in its hemoglobin.
First
The tricuspid valve pumps it through the right ventricle
Secondly
pulmonary valve pumps it from the right ventricle to the pulmonary circulation.
Then
In the alveoli of the lungs, gas exchange occurs during pulmonary circulation
The end product is oxyhemoglobin( bright red colour) I.e oxygenated blood
The next step
pulmonary veins is the means whereby the red blood cell go to the left atria from the pulmonary circulation through the aortic valve
to mitral valve then to the aorta and systemic circulation
Therefore
oxygen is replaced by carbon dioxide during systemic circulation indicating a end to cellular respiration
Lastly
It's transported back to the right atrium of the heart completing the cardiac cycle.
<u>Answer:</u>
<em>The interaction the cattle egret exhibits with the buffalo is commensalism.
</em>
<u>Explanation:</u>
<em>In the type of interaction called commensalism</em> between two organisms, one organism benefits from the other while the other <em>organism is neither benefited nor harmed. </em>
When the buffalo moves around a field grazing it disturbs the insects and they fly away from the buffalo and the cattle egret which keeps following the <em>grazing buffalo eats the insects.
</em>
The buffalo doesn’t benefit from this type of interaction. <em>A commensalism relation is a positive-neutral kind of relation.
</em>

You have also the total power generated is 200W
To figure out the kind of exercises, you need to master the definition of each unit. for example
power: watt (W) is
joule/secWork: is Newton. meter =
Joule
To obtain the work done by the adult, we have to convert the power (watt) into a work by multiplying by the time (
* seconds = Joule)
10 minutes is 60 * 10 =
600 seconds200Watt * 600 second = 120000 joules =
120 Kj
So the work is 120Kj
