Answer:
Work together to maintain a stable internal environment.
Explanation:
The given figure includes various systems like the muscular system, nervous system, circulatory system, and digestive system. These systems are involved in performing various life processes and thus, help together to maintain a stable internal environment in order to sustain life.
Answer:
- A large number of non-protein coding sequences are transcribed
- Total transcription changes over time in embryonic stem cells
Explanation:
The transcriptome refers to the totality of RNA molecules (i.e., mRNAs, microRNAs, long noncoding RNAs, etc.) that are synthesized in a given cell type/tissue/development stage. The analysis of human transcriptome has been essential to discover genes and non-coding RNAs expressed at each developmental stage, as well as genes whose expression is associated with human diseases. Next-Generation Sequencing (NGS) information showed that more than 90% of the human genome is transcribed into RNA, especially non-protein-coding sequences (i.e., non-coding RNAs). Moreover, information on the human transcriptome evidenced that global transcription changes occur in pluripotent embryonic stem cells, and these changes are mainly associated with the expression of chromatin-remodeling genes as well as genes responsible to encode the components of the general transcription machinery.
The correct answer is the law of segregation or the law of purity of gamete.
Meiosis results into the formation of gametes. The gametes are always pure for a particular trait because each gamete carries either the dominant or the recessive factor but not both as we find in F1 individuals. This follows the 'principle of segregation', the law proposed by Mendel. This law is also called 'law of purity of gametes'. The ratio 3:1 in F2 generation of a monohybrid cross suggests that alleles are segregated and the test cross confirmed it.
