The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.

Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.

Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.

Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.

Answer:

Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!

Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.

Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.

The right answers are:

create two identical cells ==> mitosis

create four non-identical cells ==> meiosis

create haploid cells ==> meiosis

creates diploid cells ==> mitosis

occurs in all cels other tha gametes ==> mitosis

occurs in all cells related to sexual reproduction ==> meiosis

Advocard [28]
These series of stages are known as the adoption process. Normally when a product comes into the market the customer does not jump to it the first time. Firstly the customer is always hesitant to go for the new product. They try to learn in details everything about the product. After learning about the product the customers give it a try to compare it with the product they were using before. Then only the customer decides whether or not to purchase the product, if it is better than the product they were using previously.

natima [27]
I would say that the most correct statement is the following one:
Certain types of renewable energy can be used for as many applications as certain types of nonrenewable resources.

Let's take for example the energy from solar panels (the renewable energy source) and the energy from burning fossil fuels: this energy can be used in the same situations!
