Because they usually are weak.

Answer:
The statement which best explains the change that must happen at the molecular level is below:
Explanation:
The molecules move more slowly and their average kinetic energy decreases
Answer:
1) K and Rb
2) 20 protons, 20 neutrons, and 20 electrons.
Explanation:
1) If it's in the same column, it has the same # of valence electrons (e- on the outer shell), therefore similar chemical properties.
2)
1) atomic #, 20, is the number of protons
2) subtract the mass number from # of protons, which you get 20 neutrons
3) Number of electrons in a neutral atom = number of electrons, which is 20. You can also check yourself by looking at electron configuration on a full periodic table.
Answer:
The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.
Explanation:
The regulation of gene is regulated and controlled by two main processes of central dogma called transcription and translation.
Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.
This process takes place in different sites in prokaryotes and eukaryotes.
In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.
Thus, the selected option is the correct answer.
