A.
<u>The ribcage expands to allow air to enter the lungs</u> is an example of the skeletal system interacting directly with the respiratory system.
Explanation:
The skeletal system is mainly made up of bones - like the ribcage in this case - while the respiratory system is made up of the lungs, trachea, diaphragm, etc.
When inhaling, the diaphragm contracts, therefore increasing the volume of the chest cavity. The muscles between the ribs also contract causing the ribcage to stretch upwards and outwards. This also contributes to an increase in the volume of chest cavity. Consequently, the pressure in the chest, decreases causing atmospheric pressure to rush air into the lungs.
When these muscles contract, they raise the pressure in the chest cavity causing air to rush out of the lungs.

Dormant oocyte 1X, growing oocyte 5X, mature oocyte 25X. Tb primary oocyte is approximately 25 micrometers in diameter. After growth, the growing oocyte will reach 200 micrometers in diameter, and eventually, the mature oocyte could reach 2 centimeters in diameter, in humans.
DNA markers between a suspect and a crime scene specimen are compared, including <span>DNA
minisatellites, short tandem repeats (STRs) and single nucleotide polymorphisms
(SNPs). The total markers that can be compared can number in the thousands, and therefore the chances of DNA fingerprinting identifying the incorrect suspect are negligible. </span>

Answer:
The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. Continental crust is less dense, thicker, and mainly composed of granite.
