Answer:
A- consisted mainly of water, carbon dioxide, carbon monoxide, and methane
Explanation:
The option A, is attributed, as the composition of the secondary atmosphere, which was generated by gases trapped within the rocks that make up the planet, but escaped during volcanic activity.
Factors that involve how each individual's genetic factors react and adjust to the environment are called INTERACTIVE ENVIRONMENTAL FACTORS.
Interactive environmental factors are the factors that are influenced by the environment and also adjust according to the environment. Sometimes the environmental factors might become stressful and the organisms need to evolve according to that stressful environment.
Answer:
O coral bleaching
Explanation:
Without the algae, corals lose their color and turn white. This is called “coral bleaching “.
Answer:
a. Bacteria cannot carry out splicing.
Explanation:
Human genes contain non-coding sequences called introns. Transcription of genes produces primary transcripts that undergo post-transcriptional modifications to produce mature mRNA. These modifications include removal of introns, the addition of 3' poly-A tail and 5' cap. The splicing of introns from primary transcripts is followed by ligation of protein-coding sequences exons to produce mature mRNA. The mRNA leaves the nucleus and serves as a template for protein synthesis.
Splicing of introns requires specific machinery such as several small nuclear ribonucleoprotein complexes, etc. which are not present in a prokaryotic cell. Therefore, a eukaryotic gene like the gene for human growth hormone is not expressed in a bacteria cell as these prokaryotic cells cannot carry out the splicing of introns from pre-mRNA.
