which characteristic(s) are used to distinguish members of the enterobacteriaceae from one another? group of answer choices both motility and the ability to ferment lactose. the presence or absence of the enzyme oxidase. both motility and the presence or absence of the enzyme oxidase. motility the ability to ferment lactose.
Litmus milk is primarily used to distinguish members within the genus Clostridium. It distinguishes Enterobacteriaceae from other gram-negative bacilli based on the ability of enteric solvents to reduce litmus.
Moreover, Enterobacteriaceae is a family of Gram-negative, facultatively anaerobic, non-spore-forming rods. Characteristics of this family include motility, catalase positive and oxidase negative includes reduction of nitrates to nitrites and acid production from glucose fermentation.
Members of the Enterobacteriaceae are bacilli, facultative anaerobes, fermenting sugars producing lactic acid, and various other end products. They are usually 1-5 μm long and have Gram-negative stains. Most have many flagella used for locomotion, but a few genera are non-motile.

What is the difference between pcr and sanger sequencing with regard to the materials needed to perform these reactions?.
Answer: The primary difference is the addition of ddNTPs in Sanger Sequencing
Explanation:
Sanger sequencing requires a DNA template, a sequencing primer, a thermostable DNA polymerase, nucleotides (dNTPs), dideoxynucleotides (ddNTPs), and buffer.
The various components required for PCR include a DNA template, DNA primers, dNTPs, and DNA polymerase.
ddNTPS lack a 3' -OH causing elongation termination which is necessary for Sanger sequencing.

1) what are rules about matter we should follow when investigating and explaining how plants grow and function?
2) what are rules about energy we should follow when investigating and explaining how plants grow, move, and function?
1.) Just as matter is made up of particles that works together to lead to the successful functionality of the system, the plant is made up of cells and tissues that function together to lead to its growth and development.
2.) Just as energy is neither created nor destroyed but can be transformed from one state to another, the energy from sunlight is being transformed to chemical energy which is being used by plants to grow, move and function.
What is matter?Matter is defined as a substance that is made up of particles that has weight and can occupy space. Matter is also made up of three major states such as solid, liquid and gas.
A plant is considered to be a matter as it is made up of cells and tissues such as the pith, protoxylem, xylem, phloem, sclerenchyma, chloroplast and cortex. These plant tissue cells obey the rules of matter as they function together to bring about the effective growth and development of the plant.
Plants also follow the rules of energy because they have the ability to transform energy from sunlight to chemical energy which is utilised for growth, movement and functioning.

(ii) Describe the stages used in the laboratory to clone and produce Tegon from the genetically
engineered cell.
Answer:
Explanation:
A small piece of circular DNA called a plasmid is extracted from the bacteria or yeast cell.A small section is then cut out of the circular plasmid by restriction enzymes, ‘molecular scissors’.The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified.The genetically modified plasmid is introduced into a new bacteria or yeast cell.This cell then divides rapidly and starts making insulin.To create large amounts of the cells, the genetically modified bacteria or yeast are grown in large fermentation vessels that contain all the nutrients they need. The more the cells divide, the more insulin is produced.When fermentation is complete, the mixture is filtered to release the insulin.The insulin is then purified and packaged into bottles and insulin pens for distribution to patients with diabetes.The DNA of an animal's somatic cell is transferred into an egg cell that has had its nucleus and DNA removed in order to create a clone. With the same genes as the cell donor, the egg develops into an embryo. The embryo is then placed inside the uterus of an adult female to develop.
What is DNA ?A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid. All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid.
The process of genetic engineering consists of three main phases. These include (1) isolating DNA fragments from a donor organism, (2) integrating an isolated donor DNA fragment into the genome of the vector, and (3) allowing the recombinant vector to develop in the proper host.
Selection, mutagenesis, conjugation, and protoplasm fusion are examples of conventional genetic modification techniques that have been used, particularly for microbial starter cultures. The latter is comparable to somatic hybridization in plant systems.

Evaluate Clara's practices for the prevention of parasite infestation in the following scenario.
Last year, Clara lost thousands of dollars when her sheep herd was infested with tapeworms. She has
always been diligent about keeping the pens clean and ensuring a proper diet. She has also always given
her sheep plenty of freedom by allowing them to wander day and night, and she even protects them from
the hot weather by putting them out to graze in the cooler evening hours. She hopes that this year the
herd will be more fortunate.
I believe Clara's actions will lessen the parasite infestation. I also believe she might arrange for routine veterinary examinations of the sheep to make sure they are free of any parasites that might infect the entire flock.
Because producers can see the visibly ejected worms whereas they cannot see stomach worms, only their symptoms or eggs, tapeworms frequently cause greater anxiety among sheep and goat farmers than stomach worms (nematodes) (in the feces).
People and animals with spines that have intestines are home to tapeworms, which are flat, ribbon-shaped worms. One of three classes of parasitic worms, they are long, segmented worms from the class Cestoda.
The move-and-dose strategy won't frequently work because many sheep pastures can't produce hay. To control parasites in this situation, prophylactic deworming treatments must be given throughout the season.
Clara's activities will therefore reduce the parasite invasion, I can infer. To ensure that the sheep are free of any parasites that could infect the entire flock, she might arrange for routine veterinarian checks of the animals.

A saturated solution is one that has as much of the solute present as is capable of dissolving. A solution is said to be unsaturated if it doesn't contain all of the solutes that can dissolve in it.
The type of material used and the temperature affect any liquid's saturation point. When the amount of dissolved solute reaches the solvent's saturation point, the solution is said to be saturated. Some specific kinds of solutes can dissolve in a solvent.
For a solution to form, a solute must be introduced to a solvent. A homogeneous solution is created when the solute dissolves in a solvent. An unsaturated solution is a term used to describe a solution in which solutes dissolve.
Accordingly, a solution is said to be unsaturated if it doesn't include all of the solutes that it is capable of dissolving. A saturated solution, on the other hand, contains as much of the solute as it is capable of dissolving.

Vaccine contain weaakened or inactive parts of the organism or antigen. It triggers the immune response of the body. If there is a mutation that caused the pretein spike to change, the effectiveness of an original vaccination will be affected. The antibodies from the vaccine are dire3cted against it and will no longer be effective and binding to destroy the virus. This will eventually escape immune surveillance. When there is a new variant, the original vaccination will not be effective completely. But somehow, it can provide at least some protection against the new virus variant. It will not make the original vaccination totally ineffective because it will still provide an elicit immune responce. It is possible to change the composition of the vaccine to provide protection against the new variants.
