Answer:
Explanation:
Duchenne muscular dystrophy acts as a X-linked recessive disease. Which means the gene sits on the X chromosome, and you need two bad copies to show disease (for females) and one bad copy (to show in males).
Now from our knowledge, we know males are XY and females are XX. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father, thus if they get the mutated version of the gene that causes this disease, they will get the disease. However, if a female has a mutated version of gene on one of the X chromosome, the other X chromosome could have a normal gene and that normal gene would take over and produce a normal phenotype/function.
Since, boys only have one X chromosome, if they get the mutated gene they will get the disease, whereas females have two X chromosome (so even if one copy is bad and the other is good, the good version can take over, however boys don't have this) thus mostly male children are affected by this.
Answer:
The system of measurement that is used through out the world is know as <u>International System of Units or, in French, Système International (SI).</u>
<u />
Explanation:
In order to describe motion, scientists use SI units to describe the distance an object moves.
<u>In system international (SI) or metric units, motion involves the units meters and seconds. </u>
Due to the consistency of units used the information described by one individual in a country is easily understandable by someone else in a different country .
For example: if someone describe the speed of an object to be 30 meters per second, anyone using the same units can understand this. whereas , the use of units such as foot per second is understandable to only small number of countries
Answer:
Use the formula K = °C + 273.15
Explanation: However, if you are given the temp in °F, then use this equation °F = 1.8(°C) + 32. You can also use this equation to convert °F →°C, which is the following: °C = °F - 32/1.8. When you find °C, then plug that into the first equation I provided in the answer!
