Answer:
1.69 moles of Xenon gas will occupy a volume of 37.8l in STP conditions
Explanation:
We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273 K of temperature.
PV=nRT ----> n=PV/RT
n= 1 atm x 37, 8 L/ 0,082 l atm/K mol x 273K
n=1,688555347 mol
Answer:
When you eat carbs, your body breaks them down into simple sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as an energy source.

Answer:
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with <u>half of the genetic material</u>. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have <u>half the number of chromosomes in body cells</u> and <u>choice A </u> is correct.
