Bears were once present as far south as California. Over time they have disappeared in most of the lower 48 states.
Human have influenced bear populations as they are a factor of resource competition for the bear species, due to the fact that the resource available in the environment have value to both humans and bears. Major changes in disturbance cycles and landscape mosaics brought by humans have further affected temporal and spatial pulses of bear food production. Air pollution has also affected bear food biomass on a small scale and is likely to have major future impacts on bear habitat climatic warming.

how many kinds of waves are there?
Answer:
There are two main waves; transverse and longitudinal. Transverse waves are like the waves we see in the ocean when we are at the beach. Longitudinal waves consist of sound, but different. Longitudinal waves have more complex properties than sound waves. They follow a consistent pattern of compressions and rarefactions within a(consistent) medium.
In-case you wonder what a medium is, a medium is the substance that carries the wave. Remember that it only transports the wave, and it plays no part in actually making the wave. When waves crash, the particles within the medium are disturbed, so they carry/pass on the disturbance to keep the wave's pattern consistent.

Any living thing (other than a virus which has no domain) that is not a bacteria or like a bacteria, is grouped into which one of the three domains?
Eukarya is the domain for grouping living thing which is not a bacterium or like a bacterium.
Bacteria, Eukarya, and Archaea are the three domains into which living organisms can be divided. The first two are all prokaryotic bacteria, which are primarily single-celled creatures with an abnormal or loosely connected nucleus. Eukarya includes all forms of life that have a cell nucleus and organelles that are membrane-bound in eukaryotes. These three domains each contain a distinct ribosomal RNA. This serves as the three-domain system's foundation. The Eukarya differ from the Archaea and Bacteria, both of which lack nuclear membranes, but the Archaea and Bacteria are distinguished from one another by specific biochemical and RNA markers. The Archaea is the first and most well-known domain. These are ancient bacterial species that were once categorized as Archaeabacteria and belonged to the kingdom Monera. Therefore, every living entity that is not a bacteria or something that resembles a bacteria is categorized as Eukarya.

A client is scheduled for elective cardioversion to treat chronic high-rate atrial fibrillation. which finding indicates that further preparation is needed for the procedure?
The finding that the client is wearing a nasal cannula delivering oxygen at 2 L per min needs further preparation for the procedure of electrical cardioversion.
Electrical cardioversion is used to treat various abnormal heart rhythms. Irregular heart rhythms can cause problems like apoplexy, stroke, or even sudden cardiac death. Artrial fibrillation (A-F) is ususally treated with this technique. A-F is a condition in which the atria of the heart shiver instead of producing a rhythm. It thus produces a rapid heartbeat and can cause a risk for apoplexy.
To start with the procedure, electrodes are stuck to the body. Electrical signals are then sent to your heart through these electrodes. Any oxygen from your body is removed before initiating the procedure because oxygen aids combustion and can result in electrical sparks inside the body and can cause flickers.
Patients are usually put on oxygen before the procedure to provide them sufficient amount of oxygen and make them stable for the procedure. Intentionally, Digoxin is kept withheld for 48 hours and food and fluids for 12 hours before the procedure.

If you made a change in the promoter sequence in the dna, what would happen at the rna level?.
If you made a change in the promoter sequence in the DNA, No RNA would be produced since the RNA polymerase would be unable to detect and bind the DNA.
Promoter sequences are DNA sequences that specify the point at which RNA polymerase starts to transcribe a gene. Typically, promoter sequences are found at the 5' end or immediately upstream of the transcription initiation point.
Promoter sequences are essential in expression vectors because they regulate how RNA polymerase binds to DNA. DNA is converted to mRNA by RNA polymerase, and mRNA is then translated into a useful protein. Thus, the promoter region regulates the expression of your gene of interest in the organism.
Promoter sequences and terminators are segments of DNA that are located upstream and downstream (respectively) of genes that regulate both the rate of transcription and the rate of mRNA degradation. Therefore, both of these components regulate the expression of a synthetic construct's net protein.

What challenges would the wildlife of the Southwest encounter after the jet stream shifted? predict what would happen to the population of the saber-tooth cats and mammoths
According to a recent analysis, the extinction of woolly mammoths and other huge animals more than 10,000 years ago was triggered by the same "trophic cascade" of ecosystem disturbance that top predators like wolves, cougars, and sharks are causing now. Researchers claim that this mass extinction was brought about by newly arriving humans tipping the scales of power and competing with powerful predators like sabre-tooth cats in a study that was just published in the journal Bioscience. A long-lasting equilibrium was upset, which could be the reason why two-thirds of North America's huge mammals disappeared during this time. Ripple stated, "We think the evidence suggests that substantial ecosystem changes, leading to these domino consequences, can be induced either by removing or introducing a major predator. "The difficulties may have started by adding a predator, in this case, humans, much as they did with woolly mammoths and sabre-tooth cats," says the author.

Describe two effects that a change in the sequence of amino acids would have on a protein.
Intricate molecules make up proteins.
The way a protein folds up determines the distinct three-dimensional form that it has. It cannot do its task in the cell if it does not fold up into the proper shape. Amino acid linkages, which are dispersed along the protein molecule, are what give a protein its shape. The bond cannot form if the incorrect amino acid is present, preventing the protein from adopting the proper shape and performing its function. For instance, the illness sickle cell anemia is brought on by a single fatal error in the amino acid sequence of the hemoglobin molecule!
Proteins are made from chemical 'constructing blocks' called amino acids. Your body uses amino acids to construct and repair muscle mass and bones and to make hormones and enzymes.

Epithelial cells of kidney tubules may have many microvilli. what is the reason for the microvilli?
To expand the surface area of the tubule and maximize the reabsorption of vital chemicals, the cells lining the proximal convoluted tubule develop microvilli. Microvilli are hair-like protrusions that come from a cell's nucleus.
Reabsorption- Water and other solutes are reabsorbed as they return from the tubule to the plasma. Over the whole length of the renal tubule, various amounts of water and particular solutes are reabsorbed.
Proximal Convoluted Tubule (PCT)- Between Bowman's capsule and the loop of Henle, the proximal convoluted part of the vertebrate nephron plays a key role in the resorption of water, sodium, and chloride ions, and sugar from the glomerular filtrate.
