Organism: Apple
All cells from the apple come from cell division occurring from the apple in order for it to grow.
An apple has multiple cells
The small living part in an apple is a cell thus showing that cells are the basic living unit.
Answer:
The following reaction will occur at cathode:
Explanation:
The two half reaction during electrolysis of aqueous nickel sulfate will be
a) anode reaction :
Water will undergo oxidation and will evolve oxygen gas at anode as shown in the given reaction:
b) Cathode reaction: The reduction of Nickel ion will occur by gain of two electrons as shown in the given equation:
Thus the overall reaction will be:
Answer:
10 Kilograms
Explanation:
"millimetres" is a unit of measurement and is used for measuring distances.
"newton" is a unit of weight and is used to represent the weight of an object
:kilograms" is the one used for measuring mass
Answer: Option (c) is the correct answer.
Explanation:
Photosynthesis is a process in which sunlight, carbon dioxide, and water is used by the plants to make their on food.
Plants absorb energy in the form of heat from the sunlight and thus produce glucose and oxygen from carbon dioxide and water. This absorbed energy is then used to start various chemical and biochemical reactions in the plants.
Hence, photosynthesis is an endothermic reaction.
Thus, we can conclude that a large amount of energy is required to activate the reaction.
Answer:
The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles).
The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.
As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.
tell me if this is wrong please
