Answer:
The cytoskeleton of a cell is made up of a few key components:
microtubules
actin filaments
intermediate filaments
Those three components/structures help give the cell its shape, and organize its parts.
I hope I helped you, and a "Brainliest" is always appreciated! ☺
<span>Decomposers break down dead
or decaying organisms, and in doing so, convert their basic materials
into forms more useful to the biological community, particularly plants.
The main decomposers in the environment include bacteria, fungi and
worms. Each of these plays a different, but overlapping, role in
decomposition</span>
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.
