Balanced forces are forces that are equal in force but opposite sides. Mary would need to push on the opposite side of Trey with the same force of 30N. (I provided a photo to visualize)

Explanation:
Answer:
They digest without the use of teeth.
Explanation:
The food trickles from the crop into the bird's stomach (proventriculus or gizzard) where digestive enzymes are added to the mix and physical grinding of the food occurs. The gizzard is why chickens do not need teeth.
Answer:
Crossing over
Explanation:
Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.
Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
Glucagon
This is a hormone that deals with blood sugar homeostasis. When blood sugar levels are low, glucagon is produced to convert the fats in the reserve back to glucose until normal levels are achieved.
Explanation:
Bone remodeling involves coordinations of osteoclasts and osteoblasts cells in the bone. The former breaks down bone tissue while the latter mineralizes bones. Calcium is the main ion in the body significant in mineralization of bone. Excess Ca2+ is stored in bone while low calcium levels in blood result in bone resorption.
Stress on a bone also causes increased mineralization to strengthen the bone against this stress. This is why astronauts when they go to space, due to less stress from low gravity, bone loses its mass. When they return back to earth, the bone readjusts to the increased stress from higher gravity by increased mineralization.
The hormone responsible for bone homeostasis is parathyroid hormone.
