Answer:
<u>Oxbow lake is formed when a bend in a river is cut off to form a lake.</u>
Explanation:
- <u>OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox. </u>
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a <u>horse-shoe shaped lake .</u>
- <u>OPTION B - It is formed when a bend in a river is cut off to form a lake.</u>
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.
- <u>OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake. </u>
This statement is also wrong, as a<u> river delta</u> is specified by this statement.
- <u>OPTION D - It is formed when a dam stops the flow of a river and creates a lake.</u>
This statement is also false, since the creation of a<u> reservoir</u> is established by this statement.
<u>FORMATION OF OXBOW LAKE -</u>: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 , <u>the correct option is B.</u>
They determine it because of the hypothesis. It changes during the investigation and the independent variable stays the same through the whole experiment.
It occurs because of contraction of the muscle layers. There are two types of muscle found in the alimentary canal; longitudinal and circular muscle, the alternating contraction of these muscles forces the bolus of food through the digestive system.
This looks like a Desert Biome to me. You can see a scarcity of plants. Spiky, cactus-like plants are also visible. You can also see the colour of the dirt. There is also no visible water source.
Answer:
Below : )
Explanation:
Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.
In this scenario, if the owl is the predator, as the population rises, its prey will decrease.
If the owl is the prey, the predators would most likely increase.
Hope this helps!
