Answer:
147,558,601 sqkm
Explanation:
The earth is spherical in shape;
area of sphere = 4πr²
if 70.8% is covered by water then 100-70.8 will be land,
= 29.2%
area occupied by land = (29.2/100) * 4πr²
= 0.292*4*3.142*(6371)²
=147,558,601 sqkm
<h2>
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.
