Answer:
V₂ = 4.7 L
Explanation:
Given data:
Initial volume = 5.0 L
Initial pressure = 1.50 atm
Final pressure = 1240 mmHg (1240/760 = 1.6 atm)
Final volume = ?
Solution:
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = 1.50 atm ×5.0 L/1.6 atm
V₂ = 7.5 atm. L /1.6 atm
V₂ = 4.7 L

Answer: a) copy tissue
Explanation:
Tissue and cells in general get damaged, or just break down from wear and tear. So the cells divide to make up for this shortcoming, effectively replacing any broken parts with fresh new ones.
<h2>
Answer:It always contains certain elements,It always contains elements in definite proportions.,It cannot contain atoms from more than one element.</h2>
Explanation:
The mineral need not occur always in a pure form.On purification we get the exact chemical composition.
The mineral always has a definite chemical composition which means the number of elements and types of elements in the mineral does not change.
Since the mineral has definite composition,the elements in the mineral has definite proportions.
The mineral can be a compound.So,there can be atoms from more than one element.
