<em>D. Molecules are made of atoms of the same element or different elements.
</em>
Explanation:
Molecules are made up of atoms. The atoms forming the molecule can be same or different. The size and function of the molecules vary from each other. The properties and function of atoms change as and when it forms a molecule.
The atoms combine with the help of a bond and it can be a covalent bond or ionic bond or hydrogen bond to form a molecule. The bond between the atoms gives shape to the molecule.
Answer:
The hill models gravity as a driving force in the water cycle.
Explanation:
Gravity (the gravitational force that pulls objects towards the centre of the Earth) drives the water cycle.
Gravity is responsible for precipitation (rain, hail, sleet, and snow) falling downwards towards the Earth's surface. It is also responsible for water at higher points on the Earth's surface flowing downwards to the lower points on the Earth's surface.
In Carlos' model, the hill represents a higher point on the Earth's surface while the valley represents a lower point on the Earth's surface. The river, flowing downwards from Carlos' hill to Carlos' valley, demonstrates the role of gravity as the driving force of the water cycle.
Yes. Penguins do have knees.
A penguin's leg is composed of a short femur, knees, tibia, and fibula.
It may seem that penguin's don't have knees when they waddle. This is because the upper leg bones of penguins are covered by its feathers, making it appear as though they have very short legs.
