Answer:
Thoracic cavity
Explanation:
The definition for pleural cavity is: The space enclosed by the pleura, which is a thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity.
Chest cavity or thoracic cavity is the space enclosed by the ribs, the vertebral column, sternum and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm.
Answer:
Changes in allele frequencies over time can indicate that genetic drift is occurring or that new mutations have been introduced into the population.
Answer:
Dominant
Explanation:
Let the allele for short tail trait be represented by "T" and allele for long tail trait be represented by "t"
When a short tailed mutant with genotype "tt" is mated with long tailed mouse, following offspring will be produced -
Tt * tt
Tt, Tt, tt, tt
so the ratio of short tailed and long tailed mouse is 1:1
Here it is given as 4:3 . Hence, there are chances that short tail trait is dominant
In the second generation , two short tailed mouse are crossed. The following offspring will be produced
Tt * Tt
TT, Tt, Tt, tt
The ration of short tailed and long tailed mouse is 3:1
Here it is given as 6:3 i.e 2:1 . Hence, short tail trait is dominant over long tail trait.

Hope this helped!
The reason as to why the breaks of a vehicle becomes hot
when they are continuously used is because of the fact that the kinetic energy that
is being used is being converted to a thermal energy, causing the brakes of the
vehicle to be hot.
