Answer:
A.producing changes in the genetic code
Explanation:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
The correct option is B. Rr × rr
Explanation:
To illustrate the results, lets make a cross between RR and rr.
r r
R Rr Rr
r rr rr
The results from the following punnet square show that there will be a 50% probability that the offsprings will have heterozygous genotype Rr and they will be round.
The results from the punnet square show that there will be a 50% probability that the offsprings will be recessive and hence will have wrinkled seeds.
Answer:
Two electrons are added to one sublevel at a time (Hund's Principle)

Mercury's SURFACE strongly resembles that of EARTH's SURFACE, with very large impact CRATERS
Mercury, the second densest of all planets shares an exterior similarity with the Earth's moon. Given the rough-like exterior feature of the moon, Mercury surface is scarred by craters due to the collisions of comets and meteroids.
The molecule which is the final electron acceptor for electrons from photosystem I is (d) NADP⁺.
Photosystem I is the protein complex involved in the process of photosynthesis. It captures the light energy to mediate the transfer of electrons from a series of electron transporters. It is involved in non-cyclic as well as cyclic photophosphorylation.
NADP⁺ is the Nicotinamide Adenine Dinucleotide Phosphate. It acts as a coenzyme. It is an important constituent in various anabolic reactions like Calvin cycle, lipid and nucleic acid syntheses, etc. The oxidized form of NADP⁺ is NADPH. It is present in organisms of almost all kinds.
