Answer:
Option (D)
Explanation:
A stream is a narrow river that originates from a source area. These source areas are usually the high altitude mountains in which the high amount of snow is gathered in the winter season and subsequently melts during the summer season. As a result of which the streams and rivers flows and mix up with the seas and oceans. These source areas are commonly termed as the headwaters or the stream head.
The direction towards the headwaters of a stream or moving against the flow direction is generally known as the upstream direction.
Hence, the correct answer is option (D).
Answer:
c. 56
Explanation:
Convert molecules --> moles --> grams
1.2 x 1024 molecules CO * 1 mol/6.022 x 1023 molecules * 28.01 g/1 mol = 55.8153438
Rounded is 56
Let me know if you need further explanation!!
Answer:
Sugar aka Glucose
Explanation:
Cellular respiration is reverse photosynthesis! Using that knowledge we know that plants release oxygen and glucose (sugar) which is what is needed for cellular respiration to occur!
Hope this helped! Stay safe and good luck!
Answer:
This substance would cause cause an extensive cellular damage to Anil.
Answer:
2.67 M
Explanation:
Molarity, which is the molar concentration of a substance, can be calculated using the formula;
M = n/V
Where;
M = molarity (M)
n = number of moles (mol)
V = volume (Litres)
Based on the provided information in this question, mass of lithium sulfate (Li2SO4) = 734g, volume = 2.5L
Using mole = mass/molar mass
Molar mass of Li2SO4 = 7(2) + 32 + 16(4)
= 14 + 32 + 64
= 110g/mol
Mole = 734/110
Mole (n) = 6.67moles
Molarity = n/V
Molarity = 6.67/2.5
Molarity = 2.668
Molarity of Li2SO4 in the solution is 2.67 M
