quizlet the second edition of bergey's manual of systematic bacteriology is largely based on classification.
The primary source for identifying prokaryotic organisms, particularly bacterial species, employing every distinguishing trait, is Bergey's Manual of Systematic Bacteriology.
Bergey's Manual was renamed as of 1984. Separate volumes of Bergey's Manual of Systematic Bacteriology are being released. There are 35 parts in this manual, each based on a different characteristic, such as overall shape, morphology, gram staining, endospore presence, motility, oxygen correlations, or method of energy production. Prokaryotae's four divisions are listed in the manual. Since the first volume of Bergey's manual of systematic bacteriology was published in 1984, a lot of work has been done on the sequencing of rRNA, DNA, and proteins, which has made it possible to conduct phylogenetic analyses of prokaryotes. As a result, the second version of Bergey's manual is released in five volumes and is primarily phylogenetic rather than phonetic, making it considerably different from the previous edition. It contains further ecological details regarding certain taxa.

During which stage does the exchange of genetic information occur?
Answer:
During this stage, homologous chromosomes line up on the metaphase plate and exchange genetic information.
Explanation:
Crossing over occurs when chromosomal homologs exchange information during metaphase of Meiosis I. During this stage, homologous chromosomes line up on the metaphase plate and exchange genetic information.
The exchange of genetic information takes place during meiosis, particularly during the prophase, resulting in organism diversification and natural selection, and sexual reproduction is the cause of the diversification.
What is the significance of the genetic exchange?During meiosis, homologous chromosomes, which are identical versions of a chromosome, pair up and exchange genetic information through a process called crossing over, and due to this, new combinations of genetic information are seen in the offspring cells. The exchange of genetic information leads to speciation, the introduction of genes into the gene pool, etc.
Hence, the exchange of genetic information takes place during meiosis, particularly during the prophase, resulting in organism diversification and natural selection, and sexual reproduction is the cause of the diversification.

What initially causes a nerve impulse? release of enzymes out of the neuron movement of chemicals into the dendrites of the neuron pathogens attacking the dendrites of the neuron red blood cells bathing the neuron
Answer:
movement of chemicals into the dendrites of the neuron
Explanation:
Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.
Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.
An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.

Use the molecular structures to predict which of the six solutions will test positive for glucose. Write your
prediction in the answer space. Provide the reasoning behind your prediction.
The reducing sugars, glucose and galactose are the two substances as shown that are able to give a positive test for glucose.
Which of the solutions would test positive for glucose?We know that glucose is a reducing sugar. There are so many monosaccharides that could be consumed in the body as well as disaccharides and polysaccharides. In either case, all the substances that fall into the categories have different ways in which they are able to interact with the Benedicts solution that is used to test for glucose. The positive test for glucose is the appearance of a brick red precipitate.
Now we know that the first structure that is shown in the image is sucrose and it does not have a free carbonyl group that would interact with the Benedicts solution. This is the same thing that occurs in the case of lactose. On the other hand, fructose is not a reducing sugar hence it does not interact with the solution.
It now follows that the reducing sugars, glucose and galactose are the two substances as shown that are able to give a positive test for glucose.

different organisms can display similar anatomical traits. for example, cats and dogs both have four limbs. why do these different animals have similar anatomical arrangements?
different organisms can display similar anatomical traits because they share common ancestral origin
Since Darwin's time, the study of comparative anatomy has mostly focused on bodily traits that are homologous, or those that, regardless of their current function, may be found in other species and share the same evolutionary ancestry. Such structures may have totally diverse appearances and serve distinct functions, yet they nonetheless share a common structure with an animal that was their ancestor. For instance, the forelimbs of humans, birds, crocodiles, bats, dolphins, and rodents have all undergone various evolutionary modifications to serve various purposes, but they can all be linked back to the fins of crossopterygian fishes, where that fundamental arrangement of bones initially developed. similar structures ,in this way they share common traits

house wouldn't have solid walls on all four sides. Instead, some of the wall areas would be replaced by substances that
water can travel through quickly, as shown in the diagram. How would this design help a house survive a tsunami? What
drawbacks might there be to this design?
Answer:
This could actually help. By doing this if the house is strong enough the water would go straight through the house just destroying furniture and anything else inside your house. This could also still hurt you the water could miss and still destroy your house so having this would have been a waste of money.

This type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.
Pinocytosis is a type of endocytosis in which a cell absorbs minute quantities of extracellular fluid (literally, "cell sipping").
The process by which the cell takes in the liquids together with dissolved tiny molecules is known as pinocytosis (the Greek word pino meaning "to drink"). The cell membrane folds during this process, forming tiny pockets that catch the cellular fluid and other dissolved materials.Pinocytosis and phagocytosis are the two primary kinds of endocytosis. Pinocytosis, commonly referred to as "cell drinking," is the process by which minute aqueous particles and the membrane receptors that identify them are taken up by the body.Big endocytic vesicles termed phagosomes are used in the process of phagocytosis, a particular type of endocytosis, to consume large particles like dead cells and bacteria.In order to absorb nutrients from the gastrointestinal tract's lumen, pinocytosis is seen in the small intestine's microvilli. Similar to this, it is seen in the kidney's duct cells while urine is being produced.Learn more about endocytosis here:

What is the independent variable?
What is the control group?
Answer:
the independent variable is salt water, the control group is fresh water
Explanation:
you are testing the effect of salt on water freezing or not. freshwater does not have salt, so it will be the control since you know it will freeze. salt water has salt, and since that is what you are testing, your salt water is your independent variable.
do not confuse your independent variable with your dependent variable!
