Answer:

1- DNA: a specific DNA sequence encodes a transcription factor which activates the expression of target genes involved in cell differentiation  

2- RNA: short non-coding RNAs may bind to enhancer regions and thus activate the expression of target genes involved in cell differentiation  

3- Environmental factor: temperature may control the expression of genes involved in cell differentiation pathways  

Explanation:

The deoxyribonucleic acid (DNA) contains the genetic material required to encode proteins. Some of these proteins are transcription factors involved in the activation of diverse signaling pathways, including, for example, cell differentiation and proliferation. On the other hand, microRNAs (miRNAs) are short non-coding RNAs that have the ability not only to repress but also to activate transcription by binding enhancer sequences. The miRNA activation mechanism has recently been discovered. In consequence, some miRNAs may potentially activate the expression of target genes involved in cell differentiation (e.g., <em>c-myc </em>gene). Finally, environmental factors (e.g., nutrient availability, salinity, temperature, etc.) may also activate gene expression and thus control diverse pathways such as cell differentiation, cell proliferation and cell death (apoptosis).

You have an organism with the following characteristics - it grows as single cells. It is heterotrophic and has a cell wall that
prisoha [69]

Answer:

Halophiles of Archaea domain

Explanation:

The Archaea are characterized as single cells. They can exihibit both the autotrophic and heterotrophic mode of nutrition. Their cell walls do not contain peptidoglycans but contain pseudo-peptidoglycans etc.  Their environmental conditions also need to be known to give a definitive identification and also are their organelles membrane bound.

Organisms reproduce in two different ways.What are they called and how do they differ?
Ganezh [65]

The two different organism reproduction is asexual which means that they can reproduce by them selves because they have both male and female parts. Sexual is when it takes two species of the opposite genders to have a offspring.
