Answer:
A
Explanation:
Channel and carrier proteins are both considered facilitated diffusion. We also know that materials do not like to go against the concentration gradient so we can eliminate B.
Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.
Explanation:
A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.
The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.
Answer:
The key difference between prokaryotic and eukaryotic ribosomes is that the prokaryotic ribosomes are 70S particles composed of 50S large subunit and 30S small subunit while the eukaryotic ribosomes are 80S particles composed of 60S large subunit and a 40S small subunit
Explanation:
Answer:
Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence and absence of core pigment and accessory pigment.
Explanation:
Photosynthetic reaction center contain core pigment known as chlorophyll A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.
Antenna complex or light harvesting complex such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.
the temperature of mercury is not regulated and the atmosphere easily floats away while being replaced with solar wind .
Mercury has a thin atmosphere.
