Photosynthesis is the process in which plants take the sun's energy and turn into nutrients for them. In other words, it's how plants eat.
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.
Answer: pubic symphysis
Explanation:
The amphiarthrosis is the joint which shows limited mobility. This joint is a kind of cartilaginous joint which unites the body of two vertebral bones.
The amphiarthrosis articulation can be seen at the pubic symphysis of the pelvis. This cartilaginous joint strongly anchors the pubic region of the right and left hip bones. This region exhibit restricted mobility. The strength of this region helps in the weight-bearing stability of the pelvis during pregnancy.
