A warm fronts move from the south to the north
<u>Explanation</u>:
A warm front are formed when a warm mass of air is pushed into a cold air mass. Since the warm air mass at surface rises above the cold mass of air they often causes stormy weathers. Also due the difficulty of warm air in pushing the cold dense air across the surface of the earth make the warm fronts to move slower when compared to cold fronts. Unstable air produces thunderstorms around the warm fronts. solid red line with red, filled-in semicircles is used to represent a warm front on the map.
The correct answer is B: The cells will have 2n chromosomes and be diploid.
Diploid cell have two of each chromosome, one from each parent. When diploid cell undergoes mitosis, the result is two identical diploid cells (when haploid cell undergoes mitosis the result is haploid cell). This means that during the mitosis, cells reproduce genetically identical copies of themselves.
Answer - A
The ratio of a child with clear skin with that of freckled skin is 1:2.
When genotype rr mates with genotype Rr, the following genotypes are expected:
Rr = clear skin dominant
rr= freckled skin
Answer:
a) The substrate 2 will be accumulated in the cells.
b) The enzyme E is mutated
Explanation:
a) The enzyme C has a mutation, the substrate 2 will not be turn into substrate 3 and this will cause to accumulation of 2.
b) when cells have 1,2,3 or 4 because of mutation of E non of these substrates cannot lead to 5. but ıf 5 gıven from the diet, the individuals can survive.
Wavelength light source is part of the control group for William’s experiment
<u>Explanation:</u>
Sir William wanted to conduct an experiment to observe how much heat passed through different colour filters of the sunlight. He directed sunlight to pass through the prism and observed vibgyor and measured the temperature. He found that the temperature increased from violet to red.
Then he was inquisitive to find the temperature beyond the red ray. That’s when he found the infrared rays which had higher temperature that was not to be seen through naked eyes. He performed experiments using the light source and found that the wavelength of light are not refracted in a particular pattern.
