The molecules in gas are farther apart and have more room to bounce around than liquid.Gas molecules expand until they are spread out through out the space they are given while liquids take the shape of their container.
Answer:
Explanation:
A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.
All the following are major pollutants of ground water except CHLORINE FROM DRINKING WATER.
Ground water refers to the water source underneath the earth surface. This water source is very important to humans and plants and it is used for various purposes. The ground water source can be contaminated by pollutants such as fertilizers, pesticides, chemicals, radioactive wastes, etc.
Chlorine from drinking water can not contaminate ground water source, this is because, the amount of chlorine added to drinking water is very small and quite safe for human consumption. Apart from this, the chlorine usually dissipate from water few hours after its addition. Thus chlorine from drinking water does not pollute ground water sources.
Answer:
44.6millilitres
Explanation:
Using the general gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
V1 = initial volume (L)
T1 = initial temperature (K)
P2 = final pressure (atm)
V2 = final volume (L)
T2 = final temperature (K)
According to this question;
V1 = 30mL
T1 = 273K (STP)
P1 = 1 atm (STP)
V2 = ?
T2 = 300K
P2 = 75.0 kPa = 75 × 0.00987 = 0.74atm
Using P1V1/T1 = P2V2/T2
1 × 30/273 = 0.74×V2/300
30/273 = 0.74V2/300
Cross multiply
300 × 30 = 273 × 0.74V2
9000 = 202.02V2
V2 = 9000/202.02
V2 = 44.55
V2 = 44.6millilitres.
Answer:
The torso, which houses the apparatus consists of upper and lower cavities that are partitioned by the diaphragm. The upper cavity is called the thoracic cavity (or colloquially the chest) and is almost totally filled with the heart and lungs; the lower the cavity, the abdomen or belly, contains much of the digestive tract and other organs and glands.
Explanation:
The torso, which houses the apparatus consists of upper and lower cavities that are partitioned by the diaphragm. The upper cavity is called the thoracic cavity (or colloquially the chest) and is almost totally filled with the heart and lungs. The thoracic cavity also contains the esophagus, the channel through which food is passed from the throat to the stomach.
The lower the cavity, the abdomen or belly, contains much of the digestive tract and other organs and glands such as the liver, the spleen, the kidneys, as well as the adrenal glands.
