Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- <u>Claim</u>: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- <u>Evidence</u>: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- <u>Reasoning</u>: <u>cohesion</u> in water depends on the force of attraction between H₂O molecules, <u>adhesion</u> is the capacity of H₂O molecules to join other different molecules and —together with <u>surface tension</u>— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.
Answer:
Balanced
Explanation:
Both forces add up to 380N.
Answer:
Chloroplasts are the food producers of the cell. They are only found in plant cells and some protists. Animal cells do not have chloroplasts. Every green plant you see is working to convert the energy of the sun into sugars. Plants are the basis of all life on Earth. They create sugars, and the byproduct of that process is the oxygen that we breathe. That process happens in the chloroplast. Mitochondria work in the opposite direction and break down the sugars and nutrients that the cell receives.
Explanation:
The options are:
A) Right Frontal Lobe
B) Right Temporal Lobe
C) Left Frontal Lobe
D) Left Parietal Lobe
E) Hypothalamus
Answer:
The correct answer is D) Left Parietal Lobe
Explanation:
Parental lobe plays an important role in combining and interpreting sensory information coming from various body parts. It process information which allows individuals to know about the position of his body parts.
The damage in the left parietal lobe will affect the right side of the body and cause numbness and impaired sensation in the right side of the body. So the individual who has damaged left parietal lobe will not able to sense any stimulus in his right hand but can still move his fingers. So the right answer is D.
