A plasmid that encodes resistance to ampicillin and tetracycline is digested with the restriction enzyme PstI, which cuts the plasmid at a single site in the ampicillin-resistance gene. The DNA is then annealed with a PstI digest of human DNA, ligated, and used to transform E. coli cells. What antibiotic-resistance phenotype(s) (characteristics) will be found on the plate
Answer: Tetracycline.
Explanation:
A plasmid is a small circular DNA molecule found in bacteria that is separate from the bacterial chromosome and replicates independently of it. They encode for certain genes that play a key role in antibiotic resistance. Restriction enzymes are endonucleases that catalyze the cleavage of phosphodiester bonds in different regions located within a DNA strand. PstI is an example of an endonuclease, it is a type II restriction enzyme produced by the microorganism Providencia stuartii that possesses a restriction target in double-stranded DNA dependent on an unmethylated, palindromic, asymmetric sequence, and in this example, it cuts the plasmid at a single site in the ampicillin-resistance gene. After that, the DNA is annealed with another fragment of DNA and this new recombinant molecule is used to transform E. coli cells. Transformation is a key step in DNA cloning because it occurs after restriction enzyme digestion and ligation treatments and transfers newly made plasmids into bacteria. So these bacterias will have a new fragment of DNA, which still has a tetracycline resistance gene but it no longer has the ampicillin resistance gene because it was disrupted by the restiction enzyme. Thereby, the antibiotic resistance phenotype is the tetracycline resistace.
The myenteric plexus is located in which layer of the alimentary canal?
A. Mucous
B. Serosa
C. Sumucosa
Answer:
A) mucous
Explanation:
The myenteric plexus is located in which layer of the alimentary canal?
A. Mucous
B. Serosa
C. Sumucosa
Wall of the alimentary canal contains four tissue layers which are
✓ the mucosa
✓ submucosa
✓muscularis
✓serosa.
The mucosa can be regarded as innermost tunic of the wall, which
serves as lines in the lumen of the digestive tract. It contains epithelium, which is an underlying loose connective tissue layer, and it reffered to as " lamina propria" along with thin layer of smooth muscle that is reffered to as" muscularis mucosa" .The myenteric plexus is found in between longitudinal layers as well as circular layer of the muscularis externa. It serves as the one that regulate neuronal intestinal motor function.
In an energy pyramid, which level has the most available energy?
A.Producer level
B.First level consumer
C.Second level consumer
D.Third level consumer
Answer:
The correct answer is -A. producer level.
Explanation:
the first trophic level is the level of photosynthetic organisms they produce their food and energy on their own from the ultimate source of energy, the Sun. This is why they are called producers.
Producers have the most energy in any ecological ecosystem as all other organisms get food from these directly or indirectly. Only 10 percent of total energy is transferred from one trophic level from producers to the next tropic level through consumers of different trophic levels.
what's assembled during the second step of protein synthesis
Answer: Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein. In the first step, called transcription, the genetic code in DNA is copied by RNA. In the second step, called translation, the genetic code in RNA is read to make a protein. A mutation is a change in the base sequence of DNA or RNA.

What organisms went extinct in the Carboniferous period
Answer: Some benthic organisms that were common to early and middle Paleozoic times began to decline during the Carboniferous. These included the trilobites (which became extinct at the end of the Permian), rugose corals, and sponges. The pelagic, or water column, environment was inhabited by a profusion of cephalopods.

Which of the following statements best describes a decomposer?
A. they are abiotic and they only eat producers they are biotic
B. they consume other biotic things for energy
C. they are biotic and they break down dead material
D. they are abiotic and they eat both plants and animals
Answer:
b
Explanation:
The statement that best describes a decomposer is that they are biotic and they break down dead material; this is option C. They break down dead organic matter, such as dead plants and animals, into simpler substances that can be used by other living organisms.
What are decomposers?Decomposers are an important part of the food chain because they break down dead organic matter into simpler substances that can be reused by other living organisms. When plants and animals die, their bodies are broken down by decomposers into nutrients such as carbon, nitrogen, and phosphorus, which are released back into the soil or water. These nutrients are then taken up by other living organisms, such as plants, which use them to grow and produce their own energy.
Hence, The statement that best describes a decomposer is that they are biotic and they break down dead material that is the option C

What is an oxygen debt? How is it repaid? Explain in detail.
Answer:
oxygen debt a state that arises in very active muscles when insufficient oxygen is supplied by the lungs, causing the muscle tissue to respire anaerobically with the production of LACTIC ACID. When muscular activities slow down, the rate and depth of breathing remains at a high level until the lactic acid has been oxidized. an oxygen debt can be repayed by breathing heavily

Explain why short bursts of light during the dark period caused the Xanthium strumarium plant to not grow.
Answer:
Due to stoppage of reactions.
Explanation:
The short bursts of light during the dark period is responsible for no growth in the Xanthium strumarium plant because this short bursts of light affected the darkness which is required by the Xanthium strumarium plant for its growth. If there is no burst of light occurs, the Xanthium strumarium plant will grow normally but when Xanthium strumarium plant receives the bursts of light, the chemical reactions that needs darkness will stop and as a result no growth occurs.
