B is the answer. But the changes would take over time
Deforestation. The animals forest that they once lived in are bein cut down.
The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.
Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed in isotonic plasma in which case water movement into the cell is equal to water movement out of the cell and so the cells remain intact.
When a plant is left in dark for several hours, it does not get sunlight. Isn't it?
When a plant does not get sunlight, it cannot prepare food for itself , i.e, photosynthesis does not take place. When it does not prepare food in the form of starch, it will test negative for it.
hope it helps!
The relationship between the wavelength of light and the quantity of energy per photon (b) they are inversely related.
Wavelength of light is defined as the distance between two crest or trough of the waves of light. The wavelength is denoted by the letter lambda (λ). Photon is simple a packet of light. It is an elementary particle that is a quantum of the electromagnetic field.
According to the Planck-Einstein relation,
E = hν (where, E = Energy of photon; h = Planck's constant and ν = frequency of oscillation)
ν = c/λ (where c = speed of light and λ = wavelength)
Therefore, E = h (c/λ)
Hence, Energy per photon is inversely proportional to wavelength of light.
