what keeps earth from flying outward into space from its present position
Answer:
Gravitational pull and the earth on its axis
Explanation:
Hope this helps
Gravitational pull and the earth on its axis keeps earth from flying outward into space from its present position.
what is Gravitational force ?A gravitational force is defined as an attractive force which is exerted by a massive body on the massive body. So our body always tries to pull other body towards itself due to this gravitational force.
gravitational force is a force exerted by earth on other objects and can be represented as F=mg
F is the force of gravity, G is the gravitational constant of the universe and it is always the same number, M is the mass of one object, m is the mass of the other object (measured in kilograms, kg), r can be the distance those objects are apart (measured in meters, m)
This force can also be called as Newton's Universal Law of Gravitation And the object that are really far apart from each other don't pull on each other noticeably either.

8 incisors. 4 canines, also called cuspids. 8 premolars, also called bicuspids. 12 molars, including 4 wisdom teeth.
Human: deciduous teeth: 212/212; adult = 2123/2123. Both childhood molars are replaced by adult premolars. Adult total is double the formula = 32. Opossum: 5134/4134 (one less incisor on each side of the lower jaw).
HOPE THIS HELPED
[tex]\huge\bold\red{Answer:-}[/tex]
The dental formula represents the arrangement of teeth in each half of the upper and the lower jaw. The entire formula is multiplied by two to represent the total number of teeth.
The dental formula for milk teeth in humans is:
[tex] \frac{2102}{2102} = 2[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth hence the zero.
The dental formula for permanent teeth in humans is:
[tex] \frac{2123}{2123} = 32[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth.

Answer:
their legs contain specialized hairs that are able to repel the water and to capture the air
Explanation:
The water strider is one of the most common aquatic insects. Water striders can sit on the water surface due to they have specialized hydrophobic water-repelling hairs in their legs that allow them to use the surface tension of water in order to distribute the weight. Thus, the hairs in the legs of these insects enable them to float and move on the water surface.
