Answer:
The correct answer is - amoeba: pseudopod; euglena: flagellum; paramecium: cilia
Explanation:
Protists use different type of structures for their movement known as pseudopods, flagella, and cillia.
Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.
A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.
Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.
Thus, the correct answer is - amoeba: pseudopod; euglena: flagellum; paramecium: cilia

The kingdom that includes the organism that causes Lyme disease would be monera.
Lyme disease is caused by bacteria in the Borrelia genus. The genus includes both burgdorferi and mayonii species.
Bacteria generally belong to the kingdom of organisms known as Monera. The kingdom is made up of unicellular organisms that are prokaryotic in nature. The cells of organisms in this kingdom lack nucleus as well as membrane-bound organelles.

#SPJ2
the maximum elongation rate during transcription with and without the modified RNA polymerase enzyme
(Figure 1).
The compound amanitin, which is commonly found in toxic mushrooms, is a specific RNA polymerase inhibitor.
Amanitin binds to the RNA polymerase active site and inhibits transcription. In a second experiment, the
scientists treated the wild-type and experimental strains of S. cerevisiae with a 40 ug/mL solution of amanitin
and recorded the maximum elongation rate of the mRNA (Figure 2).
Q. Identify the dependent variable in the experiments. Identify the control group missing from the second experiment. Justify the need for this control group in the second experiment.
Dependent variable: maximum elongation rate. Control groups: wild and experimental strains not treated with amanitin. They are important to see if the change in elongation rates depends on the amanitin inhibition or any other variable.
Before answering the question, let us first review a few concepts.
→ with the modified RNA polymerase enzyme
→ without the modified RNA polymerase enzyme
(1)The dependent variable is themaximum elongation rate
Amanitin is a specific RNA polymerase inhibitor that binds to the RNA polymerase active site and inhibits transcription.
(1) Thedependent variableis themaximum elongation rate
(2) The missing control groups arewild-type and experimental strains not treated with amanitin.
(3) The importance of including the control groups is to analyze if the change in the elongation rates depends on the amanitin inhibition or any other variable.

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!
Answer:
Pulling apart or separation of sister chromatids
Explanation:
Meiosis is a type of cell division that results in four daughter cells with each having half number of chromosomes as the parent cell. It is the cell division that leads to formation of gametes to enable sexual reproduction. Division occurs twice during meiosis because before the two halves of a duplicated chromosome called sister chromatids separate, it still needs to separate homologous chromosome, which is a similar but non-identical pair of chromosome received from both parents. Hence, meiosis occurs in a two step division process i.e. Meiosis I and Meiosis II.
Meiosis II is the mitotic division of each of the haploid cells produced in meiosis I. Note that, homologous chromosomes separate in anaphase I of meiosis I, and further undergoes cytokinesis (division of cytoplasm) to produce two haploid (reduced number of chromosomes) daughter cells.
During anaphase of meiosis II, the individual chromosomes (sister chromatids) separate at the centromeres (point of attachment between two sister chromatids). The separated chromosomes are pulled apart towards each pole of the cell by the spindle fibres.
