Answer:
The following options are true;
a) Electron transfer in the ETC is coupled to proton transfer form the matrix to the intermembrane space
c)The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions.
d) Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c.
f)Electron carriers are organized into four complexes of proteins and prosthetic groups
Explanation:
ETC involves series of steps in which electrons are passed rapidly from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, producing water. This requirement for oxygen in the final stages of the chain can be seen in the overall equation for cellular respiration, which requires both glucose and oxygen.
A complex is a structure consisting of a central atom, molecule, or protein weakly connected to surrounding atoms, molecules, or proteins. The electron transport chain is an aggregation of four of these complexes (labeled I through IV), together with associated mobile electron carriers. The electron transport chain is present in multiple copies in the inner mitochondrial membrane of eukaryotes and the plasma membrane of prokaryotes.

Answer:
mparing this value with the weight of the vehicle we see W₂> 1.6 10⁴ N
therefore the woman can lift the car
Explanation:
For this exercise on Pascal's principle, we use that the pressure in every incompressible liquid is the same
P₁ = P₂
the press is defined by
P = F / A
for the woman's side
the area of a circle is
A = π D₁² / 4
P₁ = W (4 /π d₁²)
for the car side
A₂ =π d₂²
P₂ = W₂ (4 /π d₂²)
we substitute in the first equation
W (4 /π d₁²) = W₂ 4 /π d₂²)
W / d₁² = W₂ / D₂²
W₂ = (d₂ / d₁)² W
the weight of the woman is
W = mg
we calculate
W₂ = (24/3)₂ 50 9.8
W₂ = 3,136 10⁴ N
when comparing this value with the weight of the vehicle we see
W₂> 1.6 10⁴ N
therefore the woman can lift the car
Answer: 7.175*10^18
Explanation:
Energy of a wave:
E = nhc/λ, where
E = energy of the wave
n = no of photons
h = Planck's Constant
c = speed of light
λ = wavelength of the wave
4000 = (n * 6.63*10^-34 * 3*10^8) / (510*10^-9)
4000 = 1.989*10^-25 * n / 510*10^-9
4000 = 3.9*10^-19 * n
n = 1.025*10^22 photons per second per meter²
7.0 cm² = 7.0 / 10,000 m²
= 7 x 10⁻⁴
Photons per second = 1.025*10^22 * 7 x 10⁻⁴
= 7.175*10^18 photons per second
