 Anaphylaxis,<span>serum sickness and toxicity from food are the three problems.
Anaphylaxis refers to a severe and very serious allergic reaction which should be treated right away otherwise it may caus death, Serum sickness is also similar to the allergy and in type II hypersensitivity and clinically we can say that the reaction due to the medicine that does not contain protein. Toxicity from food refers to the food poisoning that is caused by contaminated food.</span>

Suppose we were successful in identifying 12 mutants using a screen for identifying conditional mutants of S. cerevisiae in whic
Marina CMI [18]

Answer:

Each mutant would be mated to wild type and to every other mutant to create diploid strains. The diploids would be assayed for growth at permissive and restrictive temperature. Diploids formed by mating a mutant to a wild type that can grow at restrictive temperatures identify the mutation as recessive. Only recessive mutations can be studied using complementation analysis. Diploids formed by mating two recessive mutants identify mutations in the same gene if the diploid cannot grow at restrictive temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at restrictive temperature (complementation).

Explanation:

Recessive mutations are those whose phenotypic effects are only visible in homo-zygous individuals. Moreover, a complementation test is a genetic technique used to determine if two different mutations associated with a phenotype colocalize in the same <em>locus</em> (i.e., they are alleles of the same gene) or affect two different <em>loci</em>.  In diploid (2n) organisms, this test is performed by crossing two homo-zygous recessive mutants and then observing whether offspring have the wild-type phenotype. When two different recessive mutations localize in different <em>loci</em>, they can be considered as 'complementary' since the heterozygote condition may rescue the function lost in homo-zygous recessive mutants. In consequence, when two recessive mutations are combined in the same genetic background (i.e., in the same individual) and they produce the same phenotype, it is possible to determine that both mutations are alleles of the same gene/<em>locus</em>.

How large may an air mass be?
denis23 [38]
Everything has mass. The mass of something never changes. 

Mass is measured using grams.

Air is not that heavy, but it certainly has mass because it takes up space.

For every one liter of air, their is 1.19 grams.

How does artificial selection provide evidence for evolution by natural selection
Cloud [144]

Answer:

Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.

Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.

The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.

What is the function of the nucleus? A. Builds proteins B. Stores the cell's glucose C. Stores the cell's DNA D. Produces energy
Nataliya [291]
<h3><u>Appropriate</u><u> </u><u>Answer</u><u>:</u></h3>

\large{ \boxed{ \bf{ \pink{Stores \: the \: cell \: DNA(C)}}}}

Nucleus is the control centre of the cell and manages all the cellular activities taking place inside the cell. It consists of four parts :-

  • Nuclear membrane,
  • Nucleoplasm,
  • Chromatin material and
  • Nucleolus.

The Chromatin material(Condensed - Chromosome) stores the cell's DNA which is transmitted to next generation.
