however the Question is not clear, but, the geosphere is defined as the natural environment we live in. it also controls the minerals distribution, soils and rocks and generate natural hazards that shape the land and impact the lives on earth.
The major ingredient of scientific argument is scientific evidence and known science concepts. Thus through scientific idea, expectations and observations a scientific argument is given birth to. Scientific argument are usually arrived at by mean of scientific methods.
Answer:
Lead
Explanation:
The material that will warm up the fastest would be<u> lead.</u>
<em>The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit of the substance by one degree. The higher the specific heat capacity of a substance, the higher the amount of heat required to raise the temperature of the substance and vice versa.</em>
The specific heat capacity (in J/g °C) of granite, iron, copper, and lead are as follows:
Granite - 0.790
Iron - 0.450
Copper - 0.385
Lead - 0.129
From the table, <u>lead has the lowest specific heat capacity, hence, it will be the fastest to get warmed when equal masses of all the substances are placed in the sunlight.</u>
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
