Virtually all cells in the human body have the same DNA. What’s make some undifferentiated cells differentiated into brain cells

mariarad [96]

Answer:

Changes in gene expression

Explanation:

This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.

These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.

This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.

Describe two traits that represent a sustainable society and two traits of a non sustainable society

scoray [572]

<h2>The correct answer is explained below:</h2>

Explanation:

A Sustainable society can be defined as the one which utilizes the various available resources in a judicious and economical manner such that the resources can be retained for a longer period of time to be utilized by the future generations. Two traits of such a society are:

Follows the principle of 3Rs, that is Reduce, Reuse and Recycle. This means the society supports the reduction in overuse of resources, promotes the reuse of resources wherever possible and also supports the idea of recycling several resources to sustain the availability of fresh resources.
Tries to harness and make the best possible use of the available renewable resources. The society tries to maximally utilize the renewable resources to fulfill their needs.

A Non-sustainable society can be defined as the one which uses all the available resources extravagantly and profusely without showing any concern over the amount of the resources available for the future. Two traits of such a society are:

They tend to use the more readily available resources uncontrollably without any restriction and often not considering whether the resources are required immediately and essentially or not .
They tend to waste a lot of resources as often harnessing resources to an extent which is more than the requirement of the resources causes the wastage of the excess resource.

As DNA sequencing and other molecular analyses become easier and more prevalent , organisms can now be grouped into categories t

zimovet [89]

The ability to analyze DNA via DNA sequencing and other molecular analysis techniques has made it easier to group molecules into categories that represent lines of phylogeny.
Phylogeny is based on similar physical and genetic characteristics between organisms. Before such techniques, scientists were able to discern and group organisms only on the basis of their morphology, or their physical shape or appearance.
