Suppose we were successful in identifying 12 mutants using a screen for identifying conditional mutants of S. cerevisiae in which the secretory system was defective. Part A Describe the crosses you would perform to determine the number of different genes represented by the 12 mutations. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Terms can be used once, more than once, or not at all.
a. dominant
b. permissive
c. mutant
d. codominant
e. wild type
f. restrictive
g. recessive
Each mutant would be mated to ___ and to every other ____ to create diploid strains. The diploids would be assayed for growth at____ and restrictive temperature. Diploids formed by mating a mutant to a ____ that can grow at ____ temperatures identify the mutation as____ . Only ___ mutations can be studied using complementation analysis. Diploids formed by mating two ___ mutants identify mutations in the same gene if the diploid cannot grow at ___temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at____ temperature (complementation).
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 locus (i.e., they are alleles of the same gene) or affect two different loci. 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 loci, 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/locus.

Which conditions suggest that a bond will be ionic?
Answer:
A and C
Explanation:
Ionic bond is between a metal and a nonmetal
The rule is that when the electronegativity difference is greater than 2.0, the bond is considered ionic.
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

You do actually, see the entire phase of the round ball during a Full Moon. It is during when the Earth's orbital plane is inclined, or angled, by a few degrees from the ecliptic plane, meaning the Earth doesn’t block its sunlight during this time.

In simple staining with a basic dye, do the gram-positive and gram-negative bacteria differ in retaining color?
Answer:
The above shows the procedures of the Gram's staining method, The result and important of colour in differentiating the bacteria. A little insight into staining endospore.
Explanation:
Stainings is a reagent or dye used to stain microscope specimens so as to make some structures visible.
Peptidogycan is a derivative polymer of glycan and peptides found in bacterial cell walls and varies in compositional concentration from species to species.
Cell wall- A thick, fairly rigid, layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae (but not animals and other protists which generally have cell membranes without cell walls). The cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and protecting the cell from damage.
There different types of staining techniques and classification based on the aim of the experiment and here is a few;
The etymology is from Gram + positive, is named after Dan ish bacteriologist Hans Christian Gram, who invented the Gram staining technique.
Used in bacteriology , bacteria that stains dark blue or violet after Gram staining, due to large quantities of peptidoglycan in the cell wall are gram positive.
And gram-negative bacteria is one that is not stained violet by Gram's method.
A spore is thick resistant particle produced by a bacterium or protist to survive in harsh or unfavorable conditions.
Spore staining (malachite green) however can be used to differentiate sporulating bacteria species.

What do you think are uses of DNA extracted from a human cell?
Answer:
Explanation:
I think possibly about learning about diseases and to find cures and how to live longer and face products.
The DNA extracted from human cells is used for a variety of purposes, including studying gene function, gene therapy processes, genetic diseases, and developing treatments for them.
What is the purpose of the DNA?The DNA that is present in eukaryotes has plenty of function, but it can't be directly used for study of all these processes. The DNA has both introns and exon sequences in the gene, so first the introns are removed and the gene study is made.
The DNA can be used for genetic studies, to understand the genetic link between different individuals, to study the SNP, etc. The gene in the DNA can be used for recombinant DNA technology, gene therapy, and many other functions, and human DNA can be used to study mutation and its function.
Hence, the DNA extracted from human cells is used for a variety of purposes, including studying gene function, gene therapy processes, genetic diseases, and developing treatments for them.

What is the probability of tossing a coin and getting heads three times in a row?
What is the chance that the next toss will be heads? What is the chance that the next toss will be tails?
A coin flip has a 50% chance of coming up heads. This is true for every flip of the coin, so if you make it three times, your chances of getting heads are 1/2 * 1/2 * 1/2, or 1/8.
A space might look like this: HHH, HTH, THH, TTH, HHT, HTT, THT, TTT.
There are a total of eight distinct results.
If three heads appear in a row, the likelihood is,
If A, then P(getting three heads) (getting three heads)
= 1/8 ( i.e, HHH) ( i.e, HHH)
There is a 1/8 probability that you will get three consecutive heads if you flip a coin three times (i.e., HHH).

describe in general terms the intermediate species that led to the modern panda
Answer:
The intermediate species that led to the modern panda were likely carnivorous mammals that gradually evolved to have a diet that was primarily herbivorous. This evolution likely occurred over a period of millions of years and involved the development of physical adaptations such as enlarged molars and a strong jaw to help with grinding and crushing plant material. The intermediate species may also have evolved to have a more specialized digestive system to better process plant matter, as well as physical features such as a rounder head and short limbs to help with climbing and foraging in trees.
It is not known exactly what the intermediate species looked like or how many there were, but it is likely that they were small, agile mammals that lived in forests and other wooded areas. They may have had some physical similarities to modern pandas, such as a black and white coloration, but they would have differed in other ways, such as in their size, shape, and behavior.
Overall, the intermediate species that led to the modern panda were likely a diverse group of animals that evolved over time to become specialized herbivores with a unique set of physical and behavioral adaptations.
