How do the two facts above affect the described theories of the moon's origin?

Describe the relationship between the wavelength and frequency of electromagnetic waves

larisa [96]

Answer:

Frequency is inversely proportional to wavelength.

Explanation:

frequency is the number of oscillations in a unit of time.

Wavelength is the length between one oscillation and the next oscillation.

take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)

Now get two pins and pin them at a certain distance apart.

take the first spring and attach its two terminals to the pins.

Repeat the above procedure, but double (increase the distance x2) the distance between two pins.

Now you have to measure how many coils are there within 5cm of the two springs.

you'll observe that the second spring has half the coils of the first spring within 5cm.

In here no. of coils is the frequency

5cm length is time.

distance between coil is the wavelength.

A cell that contains organelles called chloroplasts

kupik [55]

Explanation:

A cell that contains organelles called Chloroplasts could be found in plants. 

Chloroplasts are organelles that conduct photosynthesis, where the chlorophyll(green pigments found in plant) captures the energy from sunlight, converts it, and stores it.A chloroplast is a type of organelle known as a plastid.

K.N. is a 24 y.o. woman who presents to the clinic complaining of sudden urgency to urinate, frequent urination, and pain with u

Murrr4er [49]

Answer: Diagnosis: The presence of nitrites in the urine confirms the urinary tract infection.

Explanation:

Treatment: The urinary tract infection will be concerned with the antibiotic therapy to kill the bacteria producing excess nitrites. Educating K.N. about the risk factors associated with the multiple sex partners and transfer of bacteria through sexual contact.

Use of fluroquinolones and nitrofurantoin:

Fluroquinolones: This is an antibiotic which has bacteriocidal property can be useful in the treatment of urinary tract infections.

Nitrofurantoin: It is an effective antibiotic in killing bacteria it gets activated inside the bacteria.

Nitrituria is a condition in which the nitrites are present in the urine that is indicative of the presence of bacterial infection. It is caused by the E. coli bacteria inside the urinary tract. It is responsible for converting the nitrates into nitrites.

PLZ HELP!!!! I'LL GIVE BRAILLIEST!!! How does a tobacco mosaic virus reproduce???

Dominik [7]

Tobacco mosaic virus (TMV) is a simple rod-shaped helical virus that contains single stranded RNA situated at its middle and is surrounded by a protein coat called capsid. After tobacco mosaic virus enters its infected host cells through mechanical inoculation, it removes its capsid to release its single stranded viral nucleic acid which is then transported into the nucleolus. The single stranded viral RNA actuates the production of specific enzymes (RNA polymerases) and it also produces another RNA strand (replicative RNA). The new viral-RNAs are transported from the nucleus into the cytoplasm and functions as messenger-RNAs (mRNAs). Each mRNA, ribosomes, and t-RNA, of the infected host cell all controls the production of protein subunits (capsomeres). After the production of the preferred capsomeres, the new viral-RNAs arrange the capsomeres around it which lead to the production of a complete virus particle (virion). The viruses then migrate from one cell to another. Hence, creating organized infection.

For natural selection to occur, variation must exist. this is true because without variation

chubhunter [2.5K]

Without variation, there is no difference between members of a population to be "selected for" in the first place. This is a basic tenet of natural selection. A new trait must arise in order to advance or decrease the fitness of the individual, and hence, its ability to pass on its genes.
