Answer: There will be stormy weather
Explanation:
Barometers is used to measure the pressure of atmosphere.
If there is sudden drop, then there will be stormy weather.
As it shows pressure is down suddenly due to which there will be storm.
If there is slowly drop in barometer, then there will be rainfall.
But if barometric pressure has dropping all day then there will stormy weather all day.
Hence , there will be stormy weather.
B) concurrent transcription and translation
C) translation in the absence of a ribosome
D) gene regulation
Answer:
The correct answer is B) concurrent transcription and translation
Explanation:
In eukaryotes transcription occurs in the nucleus of the cell then this transcript is transported outside the nucleus in the cytoplasm through the nuclear pore for translation to take place because ribosomes other important enzymes are present in the cytoplasm of the cell. So nucleus separate transcription and translation in eukaryotes.
In prokaryotes there is no such membrane-bound nucleus, therefore, the prokaryotic genetic material is present in the cytoplasm of the cell and transcription and translation runs together which means translation occur simultaneously with transcription in prokaryotes.
So in prokaryotes, concurrent transcription and translation occurs, therefore, the right answer is B.
The process that occurs in prokaryotes but not in eukaryotes is concurrent transcription and translation. Prokaryotes can synthesize mRNA and translate it into proteins simultaneously because they lack a separating nucleus, unlike eukaryotes.
The process that occurs in prokaryotes but not in eukaryotes is B) concurrent transcription and translation. In prokaryotes, due to the absence of a nucleus, mRNA synthesis (transcription) and protein synthesis (translation) occur simultaneously in the cytoplasm.
On the other hand, in eukaryotes, the nucleus separates the processes of transcription and translation; transcription occurs inside the nucleus and translation takes place in the cytoplasm. Post-transcriptional splicing, gene regulation, and translation with a ribosome all occur in both types of cells.

B) red and white alleles present on two chromosomes
C) a red allele present on both homologous chromosomes
D) a red allele present on at least one of two homologous chromosomes
Answer: The correct answer is - D) a red allele present on at least one of two homologous chromosomes (with genotype Rr).
Dominant trait (depicted by dominant allele, which is present in capital letter such as 'R' for red) is the one that masks the expression of recessive trait (depicted by small letter such as 'r' for white).
For a dominant trait to express, its genotype can be homozygous dominant ( that is having both the alleles as dominant RR) or heterozygous dominant (having both dominant and recessive allele such as Rr).
On the other hand, for a recessive trait to express, genotype must be homozygous recessive (such as rr for white flower).
In the given question, when a red flower (which could be Rr or RR genotype) is crossed with white flower (rr) and if it produces red flower, it will certainly have the heterozygous genotype that is Rr (as it will inherit 'R' allele from one parent and 'r' allele from another to become red flower).
Thus, a red allele (R) must be present on at least one of two homologous chromosomes.
