Soil creep is the downward movement of soil, on a slope, caused by the force of gravity. A slow deformation of soil material over a prolonged period of time, from pressure and stress. Creep occurs when the friction from materials resisting gravity move against each other. Slope is a key cause of soil creep.
False. gravity doesn't change motion but it's still a force
Answer:
Crossing over is the phenomenon by which homologous chromosomes exchange DNA segments between them during the process of meiosis.
If crossing over did not occur, there will be no genetic variation among parents and offsprings.
If the process of meiosis did not occur, there will be lesser chances of genetic variations to occur. Each chromosome will be either from the father or the mother with no genetic diversity present in it. As a result, genetic diversity will reduce.
Answer:
In a diploid zygote, the cause of trisomy is two sister chromatids remain joined during meiosis II (option B).
Explanation:
At the end of meiosis I, each daughter cell contains a chromosome formed by sister chromatids, each of which must be separated in meiosis II to form the gametes with a chromosome charge equivalent to half the chromosome charge of the species.
The result of the sister chromatids not separating in meiosis II -by not disjunction- results in a gamete with an extra chromosome, which when joined to another gamete results in a zygote with an additional chromosome, which is considered an aneuploidy, called trisomy.
