Answer:
The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.
Explanation:
In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.
The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.
So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.
Answer: True
Explanation:
As the adolscent period progress more responsibilities are added into the life and the person needs to be mature and responsible.
The person at this age needs to go for higher studies or can start earning.The person can either go for part time jobs.
The individual has to be more strong and independent at this age so that he can live independently and support the family.
Answer:
Perfectly cube - shaped
Explanation:
If the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:
Height×Width×number of sides and number of boxes
Surface= area of volume ratio is calculated with an equation
Area /volume
if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.
Answer:
The fossil of the dinosaur looked like it was a combination of two different types of extinct organisms: the meat-eating Tyrannosaurus rex and the Brontosaurus, which was an herbivore. Frankenstein was the name of a monster in a popular story about a scientist who built a monster in a lab. However, this species of dinosaurs evolved naturally. So, calling this species “Frankenstein” wouldn’t be completely accurate.
