What is the most harmful pesticide? However, Roundup was found in this experiment to be 125 times more toxic than glyphosate. Moreover, despite its reputation, Roundup was by far the most toxic among the herbicides and insecticides tested. Are all pesticides harmful to humans? For all pesticides to be effective against the pests they are […]
What are responsible for sending signals out to your body to start moving?
What are responsible for sending signals out to your body to start moving? The brain is the body’s control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around. How does the brain take in information? […]
What are the three ways to transfer thermal energy?
What are the three ways to transfer thermal energy? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
What is the formula of projectile motion?
What is the formula of projectile motion? The motion of such a particle is called Projectile Motion. In the above diagram, where a particle is projected at an angle θ, with an initial velocity u….Few Examples of Two – Dimensional Projectiles. Quantity Value Equation of path of projectile motion y = (tan θ0)x – gx2/2(v0cosθ0)2 […]
What is the last step in DNA replication called?
What is the last step in DNA replication called? Termination What are the major key players in DNA replication? DNA replication employs a large number of proteins and enzymes, each of which plays a critical role during the process. One of the key players is the enzyme DNA polymerase, also known as DNA pol, which […]
Will strep throat go away on OWN?
Will strep throat go away on OWN? If you have strep throat—which is caused by bacteria—your doctor may prescribe an antibiotic, such as penicillin. But strep throat goes away on its own in 3 to 7 days with or without antibiotics. Antibiotics may not make you well faster. How do you stop the feeling of […]

Can ultrasound be heard by humans?
Can ultrasound be heard by humans? Ultrasound is the name given to sound waves that have frequencies greater than 20,000Hz (20 kHz). This is above the normal hearing range for humans, so we cannot hear ultrasound. What can ultrasounds detect? Ultrasound is used to create images of soft tissue structures, such as the gallbladder, liver, […]
What does electrostatics mean?
What does electrostatics mean? Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials, such as amber, attract lightweight particles after rubbing. Electrostatics involves the buildup of charge on the surface of objects due to contact with other surfaces. How is electrostatics used […]
Why is impulse J?
Why is impulse J? In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. A resultant force causes acceleration and a change in the velocity of the body […]
