Humans have about 20, 000 to 25,000 genes.

Humans have 46 chromosomes (23 pairs), chromosomes are long strands of genes, and since the chromosomes come in pairs, so do the genes. There are 25,000 genes in the entire human genome, and since the haploid chromosome number is 23, there are about 100's of genes on the shorter chromosomes and approximately thousands on the longer chromsomes.
Humans and bacteria are related in the same way that all living things are related in that we all evolved from a common ancestor or a group of closely related ancestors. Humans and bacteria share the same genetic code as well as having many closely related genes that produce very similar protein products. For example, the genes that produce the proteins involved energy production are very similar between humans and bacteria, as well as the genes involved in the formation of many of the same basic biomolecules such as amino acids and nucleic acids.
Genes are made of DNA (or RNA - not in humans). They are sequences that encode for a functional product (usually a protein). Chromosomes contain genes.
In humans, height is governed by polygenic inheritance, which means that many different genes contribute to a person's height, rather than just one.

Different animals have different numbers of genes (and chromosomes). The exact number of genes that animals have has not been proven for many species, so estimates have been made. It is estimated that humans and mice have approximately 20,000 genes, roundworms have approximately 13,000 genes and yeast has around 6,000 genes. It should be noted that, similar to chromosome number, a larger number of genes does not necessarily mean the organism is more complex - for example rice has over 46,000 genes.
The Human Genome Project discovered that humans have about 24 000 genes.
around 30,000-40,000 genes.

Cats and humans share similar X and Y chromosomes, in fact the two species shared a common ancestor about 90 million years ago and share 90% of (homologous) genes with humans
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
