A. Metals
Metals do not have a basis of carbon
1.To produce organisms with new traits, breeders can introduce mutations (usually in bacteria) using radiation or chemicals, or they can create polyploid plants. Polyploidy describes an organism with multiple sets of chromosomes.
2.An outline of the relationship between mutations and genetic variation. A mutation is known to be a natural process in which theDNA sequences is changed in a living organisms. Although, genetic variation is the change in both alleles and genes, both throughout and amongst the population.
3. Assuming the traits are recessive, and this is not a case of incomplete dominance, begin crossing any plants you have. Hopefully, you will have two heterozygous plants (for both traits) and will see at least one trait show recessive in one of the progeny. If you are lucky, you will get two plants, one recessive for red flowers, one recessive for short stems. Cross the two, and you will get a completely recessive individual.
Answer:
A blood clot
Explanation:
It is formed to stop bleeding and foreign bodies from entering the body.
This condition is referred to as Hematochezia
Answer:
Explanation:
Hello!
The scientist created an experimental strain that produces a modified RNA polymerase with a single amino acid substitution. This mutation is supposed to change the elongation rate of the mRNA during transcription.
The dependent or response variable, is the one the researchers are interested in, meaning, are the characteristics that the researcher will pay attention to and measure during the experiment.
In this example, the researcher is interested in testing the max elongation rate during transcription, which is the dependent variable of this experiment.
In the second part of the experiment, both strains of yeast, wilds, and experimental, where exposed to 40ug/mL solution of amanitin and recorded the maximum elongation rate of the RNA. This is naturally to test the effects of amanitin over the elongation rate of the mRNA in both strains.
The control group is a set of experimental units that are exposed to the same conditions as the experimental groups, with the exception that they receive no treatment (or they receive a "no effective" treatment often called a placebo). The purpose of a control group is to know the natural response of the experimental units to a treatment-free environment, this way when comparing both groups, the researcher will be able to observe the differences or changes due to the applied treatments.
In the second experiment, there are missing two control groups, one made of the wild strain and the other made of the experimental strain, exposed to the same conditions as the treated strains.
I hope this helps!
