Unlike reptiles and amphibians, birds generate their own body heat, what does this mean for birds?
Answer:
Birds can keep themselves warn without any external heat source which is not the case with reptiles and amphibians
Explanation:
Birds are able to generate heat means they are endothermic. They generate heat through various metabolic processes. They have air pockets beneath their feathers to insulate their bodies during cold temperatures. Feathers which are modified reptilian scales help birds to streamline their exterior body and structure feathers in a way that it insulates the body.
What do you think the purpose of the blender was in your DNA extraction experiment?
Blender is used in the DNA extraction experiment. Blender is responsible for the separation of cells. This facilitates DNA extraction.
What is DNA extraction?DNA extraction is the procedure of extraction of DNA from the cell in vitro with the help of chemicals. A blender is used in extraction which separates the cells from each other. This facilitates the process of DNA extraction.
DNA is insoluble in alcohol. Addition of alcohol to the cell mixture isolates the DNA from the mixture, this results in the development of white stringy DNA at the top of the mixture. Blender is alcohol, soap, salt solution and detergent.
The basic principle of DNA isolation is disruption of the cell wall, cell membrane, and nuclear membrane as DNA is present in the nucleus. To release the highly intact DNA into solution it is followed by precipitation of DNA and removal of the contaminating biomolecules.

Certain glutamine analogs irreversibly inactivate enzymes that bind glutamine. Identify the nucleotide biosynthetic intermediates (and the enzymes that catalyze the reactions that utilize them) that accumulate in the presence of those compounds. For a given pathway, list your answers in the order of the reactions involved.
Answer:
5-phosphoribosyl-1-pyrophosphate to accumulate, PRPP will accumulate due to the inactivation of the enzyme glutamine-PRPP amidotransferase
Formylglycinamide ribonucleotide (FGAR) will accumulate due to inactivation of the enzyme formylglycinamide ribonucleotide amino transferase.
Xanthylate (XMP) will accumulates because of the inactivation of the GMP synthetase reaction.
Uridine 5'triphosphate (UTP), a nucleotide biosynthetic product as well as an intermediatein the synthesis ofCytidine 5'triphosphate will accumulate due to the inactivation of cytidylate synthetase.
Explanation:
The biosynthesis of nucleotides occurs by means of two pathways: the de novo pathways and the salvage pathways.
The de novo pathways of the synthesis of nucleotides begins with their metabolic precursors which include amino acids, ribose-5-phosphate, carbon (iv) oxide and ammonia.
The salvage pathways reuse the free bases and nucleotides from the breakdown of nucleic acids.
Glutamine analogs that irreversibly inactivate enzymes that bind glutamine will cause accumulation of intermediates in the nucleotide biosynthetic pathways.
Glutamine is used as the amino group donor in the first committed step of de novo synthesis of purine nucleotides. In this step, 5-phosphoribosyl-1-pyrophosphate, (PRPP) is converted to 5-phosphoribosylamine using the amino group of glutamine by the enzyme glutamine-PRPP amidotransferase. Inactivation of this enzyme will cause 5-phosphoribosyl-1-pyrophosphate to accumulate.
In the fourth step of the de novo synthesis of purine nucleotides, inactivation of the enzyme formylglycinamide ribonucleotide amino transferase will cause formylglycinamide ribonucleotide (FGAR) to accumulate.
In the biosynthesis of guanylate from Inosinate, the intermediate xanthylate (XMP) will accumulate due to inactivation of the enzyme xanthylate-glutamine amidotransferase.
In the de novo synthesis of pyrimidine nucleotides, Uridine 5'triphosphate (UTP), a nucleotide biosynthetic oroduct as well as an intermediate of Cytidine 5'triphosphate will accumulate due to the inactivation of cytidylate synthetase.
Carbamoyl phosphate is synthesized by the enzyme carbamoyl phosphate synthetase II using glutamine and bicarbonate and two ATP molecules. However, the other substrates of this enzyme do not accumulate.

Select ALL of the statements that accurately portray the role of natural sélection in antibiotic resistance.
Answer:
C. Some bacteria possess a gene for bacterial resistance. These Bacteria are likely to survive a course or antibiotics and reproduce.
D. Bacteria contianing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce.
E. When someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. The bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce.
Explanation:
Genes that confer resistance to antibiotics provide a selective advantage to organism that are exposed to antibiotics. So, the correct option is B.
What is Antibiotic resistance?Antimicrobial resistance occurs when microbes develop mechanisms that protect them from the effects of antimicrobials, while all classes of microbes can develop resistance. Fungi develop antifungal resistance where as viruses develop antiviral resistance.
Antimicrobial resistance mechanisms is divided into four main categories:
(1) Limiting uptake of a drug
(2) Modifying a drug target
(3) Inactivating a drug
(4) Active drug efflux.
Thus, genes that confer resistance to antibiotics provide a selective advantage to organism that are exposed to antibiotics. So, the correct option is B.

Put the following in order from
Oldest to Youngest
Unicellular Eukaryotes
Multicellular Eukaryotes
Heterotrophic Prokaryotes
Autotrophic Prokaryotes
From an evolutionary point of view prokaryotes preceded eukaryotes. Therefore it can be said that prokaryotes are older than eukaryotes.
Multicellular organisms evolved from the unicellular eukaryotes at least 1.7 billion years ago. Some unicellular eukaryotes form multicellular aggregates that appear to represent an evolutionary transition from single cells to the multicellular organisms.
The first life forms on earth were heterotrophs and atmosphere was reducing. The advent of first autotrophs also however did not immediately make the atmosphere oxidizing
The first life on the Earth began more than 3.8 billion years ago with individual cells that did not contain nuclei known as prokaryotes. These first living cells were heterotrophs meaning that they were dependent on the external nutrition sources
The earliest cells were probably the heterotrophs. Most likely they got their energy from other molecules in organic “soup.” However, by about 3 billion years ago new way of obtaining energy evolved. This new way was the photosynthesis.

I want to compare the price for a brand new Ford F150 (a truck) over the past 5 years. I have monthly estimates on what this car would cost during this time. Which graph should I use to display this data? and why?
A Line graph
B Pie Chart
C Bar Graph
To compare the price of a brand new Ford F150 over the past 5 years, it would be best to use a line graph to display this data. A line graph is a type of chart that uses a line to connect data points plotted on a coordinate plane. Line graphs are useful for showing trends and changes over time, which is exactly what you are trying to do in this case.
Using a line graph to display the price data allows you to see how the price has changed over time and to identify any trends or patterns in the data. You can also use the graph to compare the prices at different points in time and to see how the price has changed from month to month.
Additionally, a line graph is a good choice because it allows you to easily visualize the data and see how the price has changed over time. It is also easy to understand and interpret, making it a good choice for presenting the data to others.

Which of the following is not part of a flower?
a. petal
b. root
C. stamen
d. anther
The correct answer is Option (B) - Root.
It is because roots are the organs of a plant that grows downward into the soil and their primary function is to provide nutrients and take in water through the soil for the faster growth and development of the plant body. Roots are the base of a plant and provide a strong base for the plant above to sustain.
Whereas, Petals, Stamen, and Anther constitute the body of a flower. Petals are the colored parts, and Stamen consists of both Filament and Anther.
Therefore, roots do not bear leaves and are not a part of the body of a flower.
