The small size and lack of structural tissues in phytoplankton mean that aquatic primary producers achieve faster growth rates and are more nutritious to heterotrophs than their terrestrial counterparts
A curved line or surface cannot be measured by a straight scale, a measuring tape or thread must be used instead.To measure a curved line using a thread, follow the below steps:
Tie a knot at one end of the thread.
Place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight.
Place your thumb at the other end of the measured portion and measure next straighter portion.
Repeat the above step till the end of line is reached. Make a knot at the end of the line.
Now, straighten the thread and measure the length of the two knots on a scale.

describes mathematically the wave properties of electrons and other very small particles a form of energy that exhibits wavelike behavior as it travels through space, What is meant by the dual wave particle nature of light Light sometimes behaves like a wave and sometimes behaves like a particle.
Answer:
129.4g
Explanation:
Reaction equation":
4Al + 3O₂ → 2Al₂O₃
Given mass of oxygen = 115g
Unknown:
mass of aluminum metal that reacted;'
Solution:
We need to convert the given mass of O₂ to mole;
Number of moles = 
Molar mass of O₂ = 2(16) = 32g/mol
Number of moles = 
= 3.6mol
From the balanced reaction equation:
3 moles of O₂ reacted with 4 mole of Al
3.6 moles of O₂ will react with 
= 4.8mol
Mass of Al = number of moles x molar mass
Mass of Al = 4.8 x 27 = 129.4g
