Answer:
3.94 atm
Explanation:
Using the general gas law equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = ?
V = 50 L
T = 300K
n = 8 mol
Using PV = nRT
P = nRT/V
P = (8 × 0.0821 × 300) ÷ 50
P = 197.04 ÷ 50
P = 3.94 atm
Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:
Plant stems can be Underground stem, Aerial stem, and subaerial stem due to its presence and strength of the stem. Underground stem are thick stems that run below the ground surface. e.g rhizome. Aerial stems are thin stems that can not stand erect. Examples include watermelon and strawberry etc. Subaerial stems are very thin stems that do not rise up but grow just above the ground. for example, water plantain, flowering rush etc.
Answer:
In order photosynthesis to occur, plants need: water, nutrients, air, water, light, temperature, space, and time.
Explanation:
Answer:
Due to the earth's rotation and the gravitational pull of the moon.
Answer:
Incorrects:
Claim 1: When forests are cleared, we take away an opportunity to remove carbon from the atmosphere.
Claim 2: Carbon moves through biological systems and returns to the atmosphere through photosynthesis.
Claim 3: The amount of carbon involved in rapid cycling is much less than 1 percent of the total amount of carbon on Earth.
Explanation:
- The carbon contained in forest products makes a small and manageable contribution to the global carbon balance. Globally, the net effect on atmospheric concentration is negligible, unless the rate of decomposition in geographically displaced product stocks is different from that in the forest ecosystem from which it was removed. However, controlling these rates through proper management can lead to some degree of mitigation of increases in atmospheric CO2.
- During the carbon cycle, animals and plants release carbon dioxide into the atmosphere through cellular respiration, and plants capture carbon dioxide through photosynthesis.
- The amount of carbon involved in rapid cycling it is the largest since it includes the carbon exchange between living beings, and is intertwined with the carbon cycle through long-term geological processes
