A drop of mercury and a drop of water are placed on a clean glass plate. While the water flattens, mercury remains almost spherical. This happens because:

Explanation

Cohesion is the force that causes the like molecules stick together while adhesion is the force which causes the unlike molecules to cling. Since the cohesive force among mercury molecules is stronger than the adhesive force among mercury and glass molecules, it acquires spherical shape.

In a stable atom, the number of protons is the same as the number of neutrons. If the atom’s nucleus gains or loses neutrons, it may spontaneously emit particles and energy—gamma rays, for example—through a process of radioactive decay, losing neutrons and possibly protons until its nucleus stabilizes. If the atom loses only neutrons, it becomes a different isotope of the same element. But if it loses protons, it becomes a different element.
What causes radioactive decay?
Two main chemicals are responsible for the communication of the brain with the organs you have no conscious control over (heart, digestive system, endocrine system). The chemical norepinephrine helps your body get ready for a fightor-flight action by stirring up energy stores. In contrast, the chemical acetylcholine helps conserve energy by slowing the heart and increasing intestinal absorption.Which of the following situations is least likely to lead to increased levels of norepinephrine?
Positively charged particles and negatively charged particles attract each other. An oxygen atom is highly electromagnetic, which means that it attracts electrons from atoms with which it has bonded—for example, hydrogen atoms—toward its nucleus. The result is a polar bond in which the oxygen atom takes a slightly negative charge, while the other atoms take a slightly positive charge, reinforcing the bond.

Water (H2O) consists of two hydrogen atoms bonded with one oxygen atom. Which of the following explains the process described and illustrated?

As a fast-moving boat skims along the water surface, it creates ring-shaped waves that extend away from the path of the boat. If the boat is moving faster than the waves it creates, the waves form a larger, bow wave, as shown in the illustration.
Referring to the illustration, why do the circles become smaller from west to east?
Bending of plants towards the light is called
A transverse wave is one in which the oscillating (cyclical) motion of particles is perpendicular to the direction of the wave’s motion. A longitudinal wave is one in which oscillation occurs along the same axis, or in the same direction, as the wave’s motion. Which of the following creates transverse waves?
If you cut yourself and begin to bleed, the damaged tissues immediately release a chemical that initiates a chain reaction. Tiny disk-shaped platelets in your blood build up to form a plug at the injury site, and proteins in the blood plasma reinforce the clot by forming fibrous strands at the site. If a sample of blood is carefully removed from the blood vessel without allowing it to come in contact with the damaged tissue, and then the sample is placed on a smooth, plastic plate exposed to air, the blood will not clot. However, if a rough plastic plate or a glass plate is used instead, the blood will clot.
What helps cause blood to clot?

In the late twentieth century, scientists discovered a new form of life on Earth, which they called Archaeans. At the time it was discovered, this life form did not fit into scientists’ current classification scheme for biological life. It was generally believed that the vital cellular components of any living organism essentially break down at temperatures above 60° Centigrade. This thermal limit of cellular life, scientists thought, was fixed across all biological organisms. But in recent decades, Archaeans have repeatedly demonstrated that what had been thought to be the limit was too low. In fact, so-called “extremophilic” Archaeans have been discovered to thrive in temperatures as high as 160° Centigrade.
What conclusion does the discovery of Archaeans support?
