Answer:
1. Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
2. Answer: why in a single fixed pulley the velocity ratio is always more than the mechanical advantage. ... Thus effort is able to lift less load than actual effort applied and hence mechanical advantage is less than
3. Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
7. Mercury which is a metal but a liquid at room temperature. So it cannot be drawn into wires.
8. Hermaphroditic animals—mostly invertebrates such as worms, bryozoans (moss animals), trematodes (flukes), snails, slugs, and barnacles—are usually parasitic, slow-moving, or permanently attached to another animal or plant.
9. A bacteriophage is a type of virus that infects bacteria. In fact, the word "bacteriophage" literally means "bacteria eater," because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components. Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis. Bacteriophages occasionally remove a portion of their host cells' bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells. This process is known as transduction.
Explanation:
The clinical manifestation which supports this conclusion is that an injury to the brachial plexus which happens during birth. Erb is termed as a paralysis of the arm which is caused by an injury on upper arm's main nerves to be specifically the C5-C6 nerves.
It arrives most commonly on shoulder dystocia when there is a difficult birth. This paralysis can resolve on its own depending on nature of the damage.

Explanation:
The atrial natriuretic peptide (ANP), atrial natriuretic factor (ANF), atrial natriuretic hormone (ANH), or atriopeptin is a polypeptide. It is closely related to homeostatic control of body water, sodium, potassium and adipose tissue. It is released by the muscle cells of the cardiac atrium (atrial myocytes), in response to increased blood pressure. The ANP acts in order to reduce the water, sodium and fat of adipose tissue in the circulatory system thus reducing blood pressure.
It oxidies iron and inorganic sulfur compounds. The oxidation process can be harmful, as it produces sulfuric acid, which is a major pollutant. It has been suggested that T. ferrooxidans forms a symbiotic relationship with members of the genus Acidiphilium, a bacterial capable of iron reduction. Other species of Thiobacillus grow in water and sediment; there are both freshwater and marine strains.
The bacteria are usually found in rivers, canals, mine drainage effluents and mining areas. So there may be some source of these bacilli near their house.They require inorganic sources to grow and contain an enzyme called ferrous oxidase that allows them to metabolize iron.
