Paleobotany is the study of plant fossils and remains. This can help us understand how plants lived long ago and how they were like.
Hope this helps ya!
Surface area
That sign is just indicating micro
Most likely the outside atoms that are arranged around the central atom. but you didn't really give any answers. so thats my best guess.
Answer:
RNA.
Explanation:
RNA is present as genetic material in some viruses only. RNA is almost similar to DNA in its basic structure but contains oxyribose sugar and uracil instead of deoxyribose sugar and thymine.
According to RNA world hypothesis, RNA is the first genetic material evolved on earth. The RNA has the ability to store information as can be seen in process of transcription and translation. The ribozyme has the ability to acts as the enzyme. Hence, RNA has both ability to store information and catalyze the reaction.
Thus, the correct answer is option (E).
Answer: The correct answer for the blank is- has a Bb genotype, has brown eyes.
As per the information given in the question, blue eyes is a recessive ( depicted by small letter allele, b) trait and brown eyes is a dominant trait (depicted by capital letter allele, B)
A dominant allele ( like 'B' for brown eyes) always masks the expression of recessive allele ( like 'b' for blue eyes).
Heterozygous individual means a particular trait possesses both the alleles ( that is dominant and recessive allele) in the genome, which will produce a dominant trait.
The possible genotypes for brown eyes are 'BB' ( homozygous dominant) and 'Bb' (heterzygous dominant) whereas for blue eyes is 'bb'.
Thus, heterozygous individual has a Bb genotype and will produce brown eyes.
