How would the coils in the middle of the diagram
change to show a longitudinal wave with higher
energy?
They would be farther apart.
They would be closer together.
They would be shaped like a hill.
They would be shaped like a valley.
Answers
Answer:
The correct answer is - option C.
Explanation:
A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.
In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.

Answers
Answer:
biology, chemistry, and geology
Explanation:
Biology, chemistry, and geology are the fields of science that provide evidence for evolution, hence option D is correct.
What is the evidence of evolution?The uniformity of the fossil sequence from ancient to modern is possibly the strongest fossil evidence for evolution.
Fossils are a reflection of evolution and geological change due to their global distribution of organisms and distinctive traits of island species. The existence of species that are related to modern species but are now extinct is documented through fossils.
It is the series of slow, irreversible changes that occurred in early creatures over millions of years to give rise to new species we know today. Errors in DNA copying and sexual reproduction are mostly to blame for variations that led to the emergence of new species.
Therefore, biology, chemistry, and geology are the fields of science that provide evidence for evolution.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answers
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

In response to high amounts of phosphate transport into the cell: a. PhoR is phosphorylated by the phosphate transporter protein Pst b. PhoR binds with PhoB to remove PhoB repression of phosphate regulon genes c. PhoR is exported out of the cell to scavenge phosphate molecules d. PhoU changes conformation to allow PhoR to autophosphorylate e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Answers
Answer:
e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Explanation:
PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.

Yes, the Clements successional theory been subjected to peer review and publication.
What is Clements successional theory?Plant succession was characterised by Clements as a developmental process that, during the course of a community, it went through a well-defined series of stages that, in the end, resulted in a mature community, also known as the climax community. The climatic conditions that determined the climax community's existence manifested themselves in the form of an indicator and an expression of that community.
His hypothesis of community formation, sometimes known as plant succession, is what brought Clements the most fame. Even after World War II, Clements' organicism and physiological perspective were still around, albeit in a watered-down version, despite the fact that it was extensively discredited by later ecologists.

D. Nucleotide bases
Explanation:
Hope it helps.
Nucleotide bases of the DNA contain the instructions on how to control cells.
How does DNA control cells?The hundreds of distinct types of proteins that are produced by cells are coded by the nucleotide sequences that make up DNA. These proteins control and regulate cell development, division, communication with other cells, and the majority of other cellular functions. This is the reason why nucleotide sequences found in DNA are referred to as carrying or storing information.Protein synthesis:
The sequences must first be "decoded," and the protein must then be translated. It is known as protein synthesis.
Transcription (first stage of protein synthesis): The process of copying information from a strand of DNA into a messenger RNA (mRNA) molecule is called transcription. DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei.Translation (second stage of protein synthesis): The process of translation converts the information carried by messenger RNA from DNA into a string of amino acids. Essentially, it involves translating a code (nucleotide sequence) into another code (amino acid sequence).Learn more about protein synthesis here:

This virus has a single-stranded RNA genome containing about 6300 nucleotides. Its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.If the yellow mottle virus begins its infection of a cell by using its genome as mRNA, which of the following would you expect to be able to measure?
A) replication rate
B) transcription rate
C) translation rate
D) formation of new transcription factors
Answers
The correct answer is 9 proteins form each of the 20 facets of this virus. A capsid is the protein shell that surrounds a virus. A capsomere is the subunit of the capsid. Depending on the virus, capsomeres arrange in many different shapes to form the capsid. The yellow mottle virus has 20 facets, this means that it has an icosahedral capsid. Since it contains 180 identical capsomeres, we can conclude that 9 proteins form each facet.
