Answer:
Small amounts of a material are more likely to be affected by temperature, than bigger amounts of the same substance.
Explanation:
This is because of heat capacity. Heat capacity is the the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree. Water has a very high heat capacity, so the more of it there is, the harder it il be to raise its temperature.
Answer:
parallel and intersect at right angles
Explanation:
The roads in the urban areas tend to be very well organized and constructed. They tend to be parallel to each other, and also to intersect at right angels. The reason for this kind of building of the roads in the urban areas is to make the movement in the urban areas much easier and more efficient, mostly putting the accent on the traffic. It is a fact that the traffic is a big problem in the urban areas, so by constructing the roads in a well organized manner, the traffic jam eases up and the citizens can move more easily and quickly.
The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.
