Answer:
The correct answer is A. An ionic compound
Explanation:
Sodium (metal) and chlorine (nonmetal) form an ionic bond to each other, forming the NaCl (sodium chloride) molecule. Sodium transfers an electron to chlorine, which is missing an electron to complete the octet rule.
Answer:
The correct answer would be Light independent reactions require the energy gathered in the thylakoids.
Photosynthesis can divided into two sub-processes or reactions:
Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.
Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).
It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.
Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.
So, darkness indirectly affects the light-independent reaction.
Answer:
they have increased
Explanation:
What happens with pollution is that every day are tons of CO2 liberated to the atmosphere. those tons of pollution supose to be regulated by the states, but that is not what actually happens in third world countries there is an almost uncontrolable increase of CO2 liberation at the atmosphere. In the first world countries it's more controlled but still haven't decreased the CO2 levels released into the atmosphere.
The CNN (an spanish daily paper) said: the CO2 levels are the highest in the last 3 million years, in a new released the past april.
Answer:
Explanation:
Let the frequency ,
Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.
So,
![T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%20%3D%20L%5E%7Bx%7D%5BMLT%5E%7B-2%7D%20%5D%5E%7By%7D%5BML%5E%7B-1%7D%20%5D%5E%7Bz%7D%5C%5C)
collecting the like bases, we have
![T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ]](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D%20%5C%5CL%5E%7B0%7D%20M%5E%7B0%7D%20T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D)
Equating powers on both sides, we have
x + y - z = 0 (1)
y + z = 0 (2)
-2y = -1 (3)
From (3), y = 1/2
From (2), z = -y = -1/2
Substituting y and z into (1), we have
x + y - z = 0
x + 1/2 - (-1/2) = 0
x + 1/2 + 1/2 = 0
x + 1 = 0
x = -1
So,
