47 as Goldfishes are diploid! Hope I helped have a good one!
The light dependent reaction produces B NADPH and ATP which are used in the light independent reaction or dark reaction.
Explanation:
Light dependent reaction also called light reaction occur in the thylakoid of grana. Light dependent reaction leads to the generate ATP and NADPH.
Role of ATP
ATP is an energy rich compound which undergo hydrolysis to generate huge amount of free energy. ATP is formed in the cyclic photo phosphorylation by the transport of electron through various electron carrier leading to generate energy for the phosphorylation of ADP into ATP.
Role of NADPH
NADPH act as reducing agent which is formed as the end product of noncyclic photo phosphorylation.NADPH helps in the reduction of Phosphoglyceric acid(PGA) into Phosphoglyceraldehyde(PGALD). The so formed PGALD undergo further reacts to generate glucose and also to regenerate Ribulose bisphosphate(RUBP).
Introducing a predator means there will be less prey which will help balance the population of prey. Some predators may run out of food and there might be no prey left for them. If the prey were removed the predator population would decline.
Answer:
The correct option is A, since if the DNA enters in a circular form it is called a plasmid, and the plasmids upon entering the bacteria self-replicate outside the genetic structure, which gives the bacteria better survival qualities.
Explanation:
Plasmids are generally circular extrachromosomal DNA molecules that replicate and transmit independently of chromosomal DNA, and are normally present in bacteria, archaea, and sometimes in eukaryotic organisms such as yeast. Its size varies from 3 to 10 kb. The number of plasmids can vary, depending on their type, from a single copy to a few hundred per cell. Plasmid vectors allow cloning of exogenous DNA ligands of up to 4 kb since a larger size than this makes cloning in these vectors difficult. The term plasmid was first introduced by the American molecular biologist Joshua Lederberg in 1952. Plasmids can only coexist as one or more copies in each bacterium, due to cell division they can be lost in one of the secreted bacteria.
