Salutations!
A meander that has been cut off from the river is called oxbow lake. I will now give an explanation on how an oxbow lake is formed.
An oxbow lake is a narrow U-shaped lake near a river. Its a meander that got cut off.
As erosion, continues, the neck of the meander is worn away. It gets narrower and narrower. Then, during flooding, the river takes a shortcut - straight across the neck. Soon the loop of the meander gets sealed off. It turns into an oxbow lake. In time, the lake will get covered with weeds, and fill with soil, and disappear.
Hope I helped (:
Have a great day!
The answer is two molecules each will have one original strand and one new stand.

Animals do possess embryos that undergoes gastrulation where the digestive cavity and germ layers are formed, these then develop into certain tissue systems, organs etc
Animals are heterotrophs in that they are unable to symthesize their own food but rather depend on plants which are autotrophs for their food and they also lack cell wall which differentiates them from plants. Not all animals are mobile for example, sponges.
Answer:
Graph D
Explanation:
Enzyme activity will be highest at its optimum temperature.
At temperatures far below the optimum, the enzyme does not possess enough energy to work (i.e. the molecules aren't moving fast enough because of the higher temperature to increase collisions). This is called the activation energy.
At high temperatures, the enzyme can become denatured, warping its shape and catalytic activity. This means its activity will drop quite quickly until it can no longer function.
These features are all displayed in graph D.
