Answer:
The long-term increase in the temperature of the planet Earth due to certain reasons such as human activities is termed as global warming. Global warming is a concern for scientists nowadays as its consequences are very harmful to life on Earth.
Global warming causes climate changes due to which survival in extreme heat conditions will become very difficult in the near future. The greenhouse gases will cause life on Earth to be dangerous as these gases when increase than normal will be toxic. The greenhouse gases are causing the ozone layer to get depleted without which life on Earth will not be possible.
The coding instruction is read by the ribosome to produce a polypeptide chain mRNA.
Intracellular ribosomal RNA molecules form part of the protein-synthesizing organelle known as the ribosome. It is transported to the cytoplasm and helps convert messenger RNA information into protein. Each tRNA has specific amino acids that can be added to the polypeptide chain. tRNA brings its amino acids into the mRNA in a specific order.
During transcription, the enzyme RNA polymerase uses DNA as a template to produce pre-mRNAs. Pre-mRNA is processed to form mature mRNA molecules that can be translated to build the protein molecule encoded by the original gene. tRNA (transport RNA) carries amino acids to rRNA. rRNA forms ribosomes. Ribosomes use the amino acids introduced by the tRNA to build proteins according to the instructions written in the mRNA.

#SPJ4
Their reproductive isolation from each other is complete: False
They are unable to produce hybrid offspring upon interbreeding: True
They shared a common ancestor recently in evolutionary time: False
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
Diatom Cells are enclosed in a cell wall made up of silica or hydrated silicon dioxide namely frustule. The frustule has small walls where nutrients enter, enabling it to perform photosynthesis the same way plants do.
