Answer:
The result will be two gametes with a normal haploid number (n), one gamete containing an extra chromosome (n + 1) and one gamete missing one chromosome (n − 1).
Explanation:
Nondisjunction is caused by the failure in the mechanism of separation of homologous chromosomes or sister chromatids during meiosis and/or mitosis. The failure in the separation of sister chromatids during meiosis II is referred to as 'secondary nondisjunction' and it produces two daughter cells with abnormal chromosome numbers.
The fusion of one gamete containing an extra chromosome (n + 1) with a normal (n) gamete will lead to trisomy (2n + 1), while the fusion of one gamete missing one chromosome (n - 1) with a normal gamete will lead to monosomy (2n-1).
First, the sun must evaporate water. This attaches to a condensation nuclei and condenses in the cloud. Condensation occurs when warm air masses cool quickly. The two necessary conditions are for the air to be moist and warm (primarily found in low pressure zones) and for there to be dust/ other condensation nuclei in the air
The answer would be 1. original-tissue fossils and 2. many species were wiped out
Rainfall will increase due to rising temperatures which will increase the risk of flooding.
The answer is C. They are called Taxonomists.
