A new microbiology student failed to properly sterilize the pipet between creating E. coli and S. epidermidis cultures from the tablets in the lab kit. How would this mistake be recognized when the mixed culture is streak plated

Answers

Answer 1

With this error, the culture medium can be visualized with two different types of bacteria, with different stains.

In addition to staining in culture medium, what are the differences?

Escherichia coli, or E. coli, is a bacterium that naturally inhabits the intestines of people and some animals, without any signs of illness.

Staphylococcus epidermidis is a Gram positive, coagulase negative bacterium that is part of our normal flora. The microorganism colonizes human skin and mucous membranes, notably moist surfaces such as armpits, nostrils, etc.

With this information, we can conclude that this error, the culture medium can be visualized with two different types of bacteria, with different stains.

15. If out of 100 offspring, 74 are purple flowered and 26 are white, what were the likely genotypes and
phenotypes of the parents if this is a simple monohybrid cross?

Answers

Answer:

so it would be a 3 : 1 ratio.

Explanation:

The probable genotypes of the parents is Pp (Purple). When we will cross the two heterozygous purple flowers we will get the purple and white coloured flowers

The ratio would be 3:1. The parents' likely genotypes are Pp (Purple). Purple and white colored flowers will result by crossing two heterozygous purple blooms.

What are Genotypes and Phenotypes?

The type of variant existing at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.

The term "phenotype" refers to an organism's observable qualities, which are a multifactorial result of hereditary attributes and environmental factors. The physical, biochemical, physiological, and behavioral characteristics of an organism make up its phenotype.

Pp is the likely genotype of the parents (Purple). In the example presented above, combining two heterozygous purple blossoms will produce flowers that are both purple and white.

Thus, the ratio would be 3:1. The parents' likely genotypes are Pp (Purple). Purple and white colored flowers will result by crossing two heterozygous purple blooms.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to determine the p squared value?

Answers

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

What is a recessive phenotype?

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

p^2 + 2pq + q^2 = 1

where;

p^2 is the h0m0zygous dominant phenotype frequency2pq is the heterozygous phenotype frequencyq^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Which statement best describes how organisms use DNA and amino acids to synthesize protein?
1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.
2 DNA is translated into mRNA, which is transcribed by the ribosome to produce an amino acid chain
3 Amino acids are transcribed into mRNA, which is translated into the nucleus to produce a molecule of DNA.
4 Amino acids are translated into mRNA, which is transcribed in the nucleus to produce a molecule of DNA.

Answers

Answer:

1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.

Explanation:

The steps of the process are always from DNA to mRNA to amino acids. This is because DNA can't travel out of the nucleus. So, DNA must be converted to mRNA to travel out of the nucleus. Only mRNA can leave the nucleus. The m in mRNA stands for messenger, so think of mRNA as the messenger from DNA to amino acids. Then the mRNA must be converted to amino acids to produce a protein.

So, options 3 and 4 are eliminated.

The process of DNA to mRNA is called Transcription. The act of transcription is called transcribing.

The process of mRNA to amino acid is called translation. The act of translation is translating.

The only option that fits this category is option 1.

Flatworms are free-living or parasitic animals, with bilateral symmetry, triblastic and with no coelom. The correct answer is FLATWORMS.

What are the flatworms?

These are animals of variable size, going from a few millimeters to centimeters.

Flatworms are bilateral, acoelomated, and triblastic animals. The fact of being acoelomate means that they lack an internal cavity. Their whole body is solid, having mesenchyme where different organs are located.

Sense organs are located in the anterior part of the body.

These animals are hermaphrodites, exhibiting cross reproduction and eventually autofecundation.

What happens to energy from the Sun when it reaches Earth

Answers

Answer:

The energy from the sun that reaches Earth’s surface is mostly “shortwave” radiation – mostly visible light. This energy passes freely through the atmosphere and is absorbed by Earth’s surface. The surface warms from the energy input, and some of its heat projects back to the atmosphere as infrared radiation.

Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth’s surface. … Shortwave radiation reflected back to space by clouds.

Each embryo has some type of tail bone, whether it may or may not be used when actually born.
