Answer:
C. His mother carried at least one allele for that trait
Explanation:
-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.
-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.
-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
Answer:
Capillary refill time
Explanation:
Capillary refill time refers to the time that it takes for color to return to an external capillary bed after pressure has been applied (which causes blanching). Usually, on healthy individuals, capillary refill time takes less than 2 seconds. If the time is much longer, this could indicate problems such as shock, dehydration or peripheral artery disease.
when John Travoltage rubbed his foot against the floor, he started building up negative energy, this negative energy later built up as he was rubbing his foot on the floor which then caused a reaction with the door knob, the same thing happened with the balloons, as we rubbed it on the sweater, the balloons started building up negative energy too, which then resulted in a connection with the positive energy. The dust particles most likely got a charge from moving around from different places, considering that fabrics build up the negative energy, it appears that the dust particles could have landed on a fabric which then allowed the particles to build it up and then stick to other surfaces.
Explanation:
Sun plays an important role in our solar system especially planet like earth are dependent on sun for food, water and air. Sun helps to balance the ecosystem on earth.
Here is an assumption what would happen if sun disappear for one day only, it would be more curt if it disappear forever but from POV of one day below are certain consequences of such a situation over solar system,
- You might be thinking if sun disappear then we would be seeing the moon for a whole day but don't forget, moon don't have it's own light, it reflects the rays coming from sun if sun disappear then surely moon would be like a ball kept in dark.

- There's a idiom in Indian Hindi language that says "seeing the stars during the day time" which we use when we are going through something worse that we see the stars during daytime, but this time every human being on earth will see the stars during daytime, do not forget stars have their own light, they are not sun dependent.
- For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.
- Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.
- people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.
- Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.
- Our ozon layer will have it's first leave from his duty.
- The bad thing is for the patients of night blindness, they will not be able to see this imaginary scene.

By contracting, muscles pull on bones and allow the body to move. ... Each muscle in the pair works against the other to move bones at the joints of the body. The muscle that contracts to cause a joint to bend is called the flexor. The muscle that contracts to cause the joint to straighten is called the extensor
