Answer:
D. Partial pressure
Explanation:
Partial pressure is the individual pressure exerted by each gas present in a gaseous mixture. As he is measuring the pressure of each gas in the atmosphere separately, so PARTIAL PRESSURE is the exact term for his measurement.

Answer:
B) A drawn bow is released, causing an arrow to fly across the field
Explanation:
Potential energy can be thought of as "potential" to do something. For eg, putting a ball on top of hill causes the ball to have the potential to roll down the hill if released. Here the ball converts the potential energy into kinetic energy (energy of motion) to roll down.
Similarly, the bow has been stretched (potential to fly if released), and when its released, it converts the potential energy into kinetic energy.
Answer:
Yes
Explanation:
A single covalent bond forms when two atoms share one pair of electrons.
Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.
- To form a covalent bond, each of the two participating atoms would put down an unpaired electron.
- The unpaired electrons form a shared pair of electrons between them.
- This shared pair of electrons constitutes the electron cloud that binds the two atoms together.
- The shared pair of electron is the covalent bond.
i) Las bacterias son organismos microscópicos unicelulares que prosperan en diversos entornos. Estos organismos pueden vivir en el suelo, el océano y dentro del intestino humano.
ii) Un virus es un agente infeccioso submicroscópico que se replica solo dentro de las células vivas de un organismo. Los virus infectan todas las formas de vida, desde animales y plantas hasta microorganismos, incluidas bacterias y arqueas.
