Question 1: The answer is (a.) Osteichthyes
- Goldfish, Tilapia, and Barracuda most likely belong to this superclass. 90% of the fishes in the sea belongs here.
Question 2: The answer is (c.) Agnatha
- These type of fishes are eel-like in appearance like a lamprey.
Question 3: The answer is (d.) Countershade
- It is a form of camouflage in which animal's pigmentation is lighter on the underside and darker on the upper side like sharks.
The equation for the thermal efficiency of a system is given by n = Tc/Thx100
where n is the thermal efficiency, Tc is the temperature of the cold reservoir
and Th is the temperature of the hot reservoir. Dividing 190 by 515 gives us an
efficiency of 36.9%.
The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.
In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.
All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.
D. H2O > NADP+ >Calvin Cycle. Light Reaction during photosynthesis represents the flow of electrons. Electrons are extracted from water by an enzyme then go to photosynthesis II via electron transport chain. Electrons from the protein are transferred to NADP to form NADPH.
