Define polarity and explain why it occurs

Biology
1 answer:
Sergio [31]3 years ago
8 0

“A state or a condition of an atom or a molecule having positive and also negative charges, especially in case of magnetic or electrical poles.” Polarity, in general, refers to the physical properties of compounds such as boiling point, melting points, and their solubilities.

Polarity results from the uneven partial charge distribution between various atoms in a compound. Electrons in a polar covalent bond are unequally shared between the two bonded atoms, which results in partial positive and negative charges. The separation of the partial charges creates a dipole.

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of___.
dmitriy555 [2]

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.

A. 7.5 feet

<u>Explanation:</u>

Wave base defines the depth of the water when it is in still condition.

Wave base is half of wavelength.

Wave base = wavelength/2

Given,

Wavelength = 15 feet

So, wave base = 15 feet/2 = 7.5 feet

When the wave height is divided by wavelength then it gives the steepness of the wave.

Therefore, the wave base is 7.5feet.

For the answer to the question above, <span>Blurred Vision

A severe headache, visual disturbances such as blurred vision and some epigastric pain that is associated with the development of severe pre-eclampsia or eclampsia. These danger signs and symptoms must be reported immediately as soon as possible. A severe headache and visual disturbances are related to severe vasoconstriction and in a severe increase in blood pressure. Epigastric pain is related to hepatic dysfunction. Ankle edema is a common thing during the third trimester of pregnancy. However, the facial edema is associated with increased fluid retention and the progression from mild to severe pre-eclampsia. Increased energy levels aren't associated with a progression of the client's pre-eclampsia or the development of the complications. In fact, some women are reporting an "energy spurt" before the onset of labor. A mild back-ache is just a common discomfort of pregnancy, unrelated to a progression of the client's pre-eclampsia. It also may be associated with bed rest when the mattress is not firm. Some multi-parous women have reported a mild backache as a sign of impending labor.</span>

PLEASE HELP!! im despratte
Alex73 [517]

Answer:

Template strand = complementary strand

GCA AG = CGT TC

TTA CG = AAT GC

GAT AC = CTA TG

CGG AT = GCC TA

DNA strand = mRNA strand

CGA TT = GCU AA

GCT TA = CGA AU

GCA TC = CGU AG

TTC AT = AAG UA

It is more important for DNA replication to be exact than transcription or translation because any error that occurs during DNA replication if not repaired will become permanent and will be transferred to the next generation.

Explanation: In DNA base pairing, G pairs with C and T pairs with A. But in RNA base pairing, G pairs with C and U pairs with A. DNA contains four bases G, C, T and A while RNA contains four bases G, C, A and U.
