Mutation usually occurs when there is an error in the pairing of gametes during the crossing over stage of meiosis. There are many types of chromosomal mutation and these are: translocation, duplication, deletion, and inversion. Changes in the number of chromosomes may lead to unique changes in physical and behavioral traits of organisms.
Answer:
C) a mature river
Explanation:
The channel on the image shows a meandering river. This basically means that the river managed to erode the banks and it has taken a snake-like shape, better known as meander. A river that exhibits such a thing is a mature river. This can be supported by the fact that the river needs long time to be able to erode the surrounding area, especially when it comes to flatter land. A young river will be mostly straight and will have its flow determined by the landscape around it, but a mature river has had the time to make its own path, to erode parts o the landscape, and take a certain shape, in this case a meander.

Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
