Answer: (A) Only differentiation is a process that results from stem cell division.
Explanation:
Cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Differentiation occurs many times during the development of a multicellular organism. The organism changes from a single zygote to a complex system of tissues and cell types.
Answer:
1. Water vapor condenses to form clouds.
2. Water falls as rain, snow, and sleet.
3. Water flows down mountains and hills.
4. Water joins streams or forms groundwater.
Answer:
The correct option is A.
Explanation:
As we know that genetic variation that result from crossing over depend on the number of genes and their alleles. When there are more genes in genome the chances of polymorphic loci will increase, which will result into more genetic variation during crossing over.
Forexample:
Drosophila melanogaster is a common fruit fly having diploid number of 8 chromosome composed of 122,653,977 base pairs, and about ~17,000 genes. Honey bees have diploid number of 32 chromosomes composed of approximately 2360000 base pairs, and 10,000 genes.
Conclusion:
As fruit fly genome contain more genes and polymorphic loci, so genetic variation is more likely to be greater in fruit fly.
Answer:
The red curved line in the map provided is the Mid-Oceanic ridge (MOR), which is here known as the Mid-Atlantic ridge, and is the result of the divergent plate boundary where the two plates move away from each other in the opposite direction
