Abiotic factors are the non-living components of an ecosystem. ... Biotic and abiotic factors both influence each other.
Answer:
D) transcriptional control of gene expression.
Explanation:
Enhancers as the name indicates are required to enhance transcription of a gene. Enhancers are nothing but a small stretch of DNA which may be located either in upstream (mainly) or downstream region of a particular gene. If they are distantly located from a gene then in order to cause increased transcription of that gene they form a loop to reach near the promoter region of the gene. With the help of activators and transcription factors they can enhance the expression of gene at transcriptional level.
There are many effects to deforestation but the main one would be loss of habitats.it can also cause climate change also trees hold a major role in holding in greenhouse gases.
<span>The embryonic period is the most important phase of development for organ formation. The embryonic period in humans begins at the moment of fertilization and continues until the end of the tenth week of gestation. Rapid growth and differentiation occurs during this period, which produces varied cell types.</span>
the role of plants in carbon cycle
Explanation:
the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
