The main differences between a plant cell and animal cells is that plant cells have more of a rectangular shape because the cell wall is more rigid. While animal cells have more of a circular or irregular shape because they don't have a cell wall. Plant cells usually have one or more large vacuoles, while animal cells have smaller vacuoles if any are present.
To solve this problem, we must be given first the density
of air at 20 degrees Celsius. Looking up online, this is equal to:
density air (20C) = 0.0012041 g/mL
so that the volume is:
volume balloon = 0.57 g / (0.0012041
g/mL)
<span>volume balloon = 473.38 mL</span>
Answer:
Experiment Question, Independent & Dependent Variable, Null & Alternate Hypothesis
Explanation:
Experiment Question : Whether fine cloth coverage over chicken jars effect flies & their eggs in ambience ?
Independent Variable : The causal variable, ie cloth cover existence on the chicken jar
Dependent Variable : The resultant variable, ie presence of flies & their eggs near jar, meat
Null Hypothesis [H0] : Cloth cover on chicken jar doesn't effects flies' & eggs' presence around jar, chicken.
Alternate Hypothesis [H1] : Cloth cover on chicken jar effects flies' & eggs' presence around jar, chicken.
