Answer:
1) Plant cells have large sized vacoles than animal cells.
2) Plant cells have plastids and animal cell do not.
3) Plant cells have chloroplasts and animal cell don't.
4) Plant cells have cell walls and animals cells don't.
Explanation:
If the tree is 30 m around, then shouldn't we take the lengths of the arms and divide it into the perimeter of the tree? So what we do is take 30/1.3 = about 23. So it would take about 23 children to stretch their arms around the tree.
<h3>The answer is:</h3><h2>Hypothesis</h2>
A theory is an educated guess and so is a hypothesis. They both have limited evidence as a starting point for further investigation.

Carbon is a reactant in the process of photosynthesis but a product in the process of cellular respiration.
<h3>What is carbon cycle?</h3>
Carbon cycle is the physical cycle of carbon through the Earth’s biosphere, geosphere, hydrosphere and atmosphere.
It is the series of processes by which carbon compounds are interconverted in the environment, that includes such processes as
- photosynthesis
- decomposition
- respiration
- carbonification
Carbon cycle involves the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
Therefore, carbon is present in the atmosphere as a reactant during photosynthesis and as a product during cellular respiration.
