I hope that's help :)
C. The Roots and Mycelium
Both are the best similar structures between plants and fungi as these parts serves as the channels which transports all the nutrients from the soil/host to the plant/fungi.
Answer:
Plasmid DNA play a important role for survival of a prokaryotic cell.
Option D is correct one.
Explanation:
In addition to the chromosome, many prokaryotes have plasmids, which are small rings of double-stranded extra-chromosomal ("outside the chromosome") DNA. Plasmids carry a small number of non-essential genes and are copied independently of the chromosome inside the cell. They can be transferred to other prokaryotes in a population, sometimes spreading genes that are beneficial to survival.
For instance, some plasmids carry genes that make bacteria resistant to antibiotics. (These genes are called R genes.) When the plasmids carrying R genes are exchanged in a population, they can quickly make the population resistant to antibiotic drugs. While beneficial to the bacteria, this process can make it difficult for doctors to treat harmful bacterial infections.
Answer: The correct answer is C) Although the F1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.
According to Mendelian inheritance, true breeding parents ( which are homozygous dominant and homozygous recessive) for dominant and recessive allele will always result into offsprings with heterozygous dominant genotype.
As per the question, genotype of P ( parental ) generation is AA and aa. When they are crossed together, they result into Aa offsprings, which all exhibit dominant character/ phenotype. These offsprings will increase the chances of future variation.
This type of passive transportation is called OSMOSIS.
Osmosis is a type of passive transportation in which a liquid moves from the region of high concentration to the region of low concentration. The movement usually continues until the amount of liquid on both sides are the same. This type of movement does not require energy because the flow is naturally favored, that is, molecules moves from high end to low end.
