The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".
<u>Option: B</u>
<u>Explanation:</u>
In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.
Chromosomal mutations are often caused by chemical agents or by mutagens.
The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.
Answer:
Hereditary factors do not combine but are passed on in the same form they were inherited.
Explanation:
Answer:
1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included.
2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape.
3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve.
4. No, because the sugar would dissolve.
5. No, on this case the displacement method would not work because of the weight difference
Explanation:
all the answers for you!
Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere.
• Droughts are becoming longer and more extreme around the world.
• Tropical storms becoming more severe due to warmer ocean water temperatures.
• As temperatures rise there is less snowpack in mountain ranges and polar areas and the snow melts faster.
• Overall, glaciers are melting at a faster rate.
• Sea ice in the Arctic Ocean around the North Pole is melting faster with the warmer temperatures.
• Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere.
• Sea levels are rising, threatening coastal communities and estuarine ecosystems.

Explanation:
Plant roots complete a cycle in the soil. The deeper they go, the more benefits they provide to soil fertility and stable carbon storage in soils. While alive and active, roots redistribute carbon and nutrients throughout the soil profile.
