Answer:Answer: Given m = 10 kg and . F = 20 N. Thus, the force required to accelerate the object upward direction is 20 N.
Explanation:
Plants do not obtain phosphorus while using active transport.
Answer: Booster dose of vaccine is given to elicit a secondary immune response ( by means of re-exposure of pathogen in the booster dose) so that more number of long lived antibody producing plasma cells are produced in the body.
Due to this, a higher level of protection is created in the body.
Whenever the body encounters the disease causing agent, it can easily clear off the infection.
Thus, booster dose serves as an additional vaccine dose to boost the memory of the immune system against a particular disease.
Example of vaccine that require booster dose- HPV ( human pappiloma virus), Hepatits A, Hepatitis B, Polio.
The right answer is A) DNA.
During evolution, the mitochondria have retained their own genome, which, although very small compared to that of a bacterium, is essential for the proper functioning of these organelles. Confined within the mitochondria, organelles that produce cellular energy, the mitochondrial genome (mtDNA) is distinct from the DNA in the nucleus. The transmission of this DNA is generally called non-Mendelian because it is only transmitted by the mother.
Chloroplasts contain DNA grouped into nucleoids; each chloroplast can contain up to 100 copies of the genome. The DNA molecules of the chloroplast genome are generally linear or branched. The chloroplast genome is very small, 37 to 220 kb and usually contains about a hundred genes
