Answer:
Oxbow lake is formed when a bend in a river is cut off to form a lake.
Explanation:
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .
This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.
This statement is also wrong, as a river delta is specified by this statement.
This statement is also false, since the creation of a reservoir is established by this statement.
FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.
Hence , the correct option is B.
Answer:
Bbbb
Explanation:
Which of the images below represents a healthy coral reef ecosystem?
In the given image below image A represents a healthy coral reef ecosystem. Thus option A is correct.
The ecosystem present underwater and designed as building of reef and corals. Reefs are made up of colonies of coral polyps accumulated together in the form calcium carbonate.
Maximum coral reefs are made up of corals of stone and they protect coastlines from heavy storms and it is the great source of employment for local people. Coral reefs provides medicines as well as foods to a high number of population.
Coral reefs are sometimes get damaged from local and outer sources due to construction work and destructive fishing and provides medicines as well as foods to a high number of population.
Therefore,In the given image below image A represents a healthy coral reef ecosystem. Thus option A is correct.

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, along electromagnetic spectrum, wavelength increases, frequency decreases.
Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.
There is a relation between energy of wave. frequency of wave, and wavelength of wave
Mathematically,
E=hc/λ
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
c is speed of light that is 3×10⁸m/s
λ is the wavelength of electromagnetic wave
Wavelength is inversely proportional to frequency of wave. From left to right in electromagnetic spectrum, wavelength increases.
Therefore, along electromagnetic spectrum, wavelength increases, frequency decreases.

b. mitochondria
c. ribosome
d. vacuole
This part of the cell stores wastes, water or food is vacuole. TThus, option D is correct.
The vacuole is an organelle found in both plant and animal cells that stores various substances, including wastes, water, and food. It plays a crucial role in regulating the cell's internal environment and maintaining cell turgor pressure in plant cells.
Lysosomes are responsible for the digestion and elimination of cellular waste materials, mitochondria are the powerhouse of the cell involved in energy production, and ribosomes are involved in protein synthesis.
