Answer:
P(total) = 978 mmHg
Explanation:
Given data:
Total pressure of gas = ?
Partial pressure of O₂ gas = 200 mmHg
Partial pressure of N₂ gas = 350 mmHg
Partial pressure of He gas = 428 mmHg
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 200 mmHg + 350 mmHg + 428 mmHg
P(total) = 978 mmHg
Sonia observed that the two balloons repelled each other. This is because both balloons acquired the same charge when she rubbed them with the piece of wool, and like charges repel each other.
Hydroxide is the full name of the compound.

Question</h2>
I think the actual question should say "What is true of most body cells except skin cells?" I found this on another source.
Answer:
B
Explanation:
A is false for all cell types. In every cell, genes are organised into chromosomes in the same way. However, the way they are expressed is different between different cells.
C - is false for all cell types - all cells contain the same chromosomes with the same genes.
D - is false. All cells contain the same chromosomes and genes, it is the expression patterns of the genes that direct cell identity.
B is true, each body cell contains the same genes and chromosomes. The only exception is the sex chromosomes, which are haploid and genetically unique. This means that when fertilisation occurs following sexual reproduction, the diploid state is restored and a genetically unique organism is created.
