Answer:
so what question shall we answer?
Homologous chromosomes pair up and exchange segments of DNA.
Option A
<h3><u>Explanation:</u></h3>
Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.
The words needed to fill the spaces and to complete the statement above are trees, grass, soil, and shrubs, respectively. In terms of biology, a succession is a process of evolving the structure of a biological population over time, who has two types- primary and secondary.
Sensory neurons are types of brain cells that convert the stimuli coming from the senses (hearing, touch, smell, taste, and sight) into information that would allow the brain to interpret it as a sensation. For example, they convert the messages from the optical nerve if the object is of a light color or not.
Answer:
During the final scene, lightning strikes the Pride Land igniting a fire that burns out the existing dead brush and trees. This fire is symbolic of the end of an era of an unstable ecosystem. As time passes, pride rock is transformed back into a healthy climax community.
