<h2><em>explain how surface water is able to form on permafrosts able to form on permafrost</em></h2>
- <em>Just as a puddle of water freezes on a frigid winter night, <u>water that is trapped in sediment, soil, and the cracks, crevices, and pores of rocks turns to ice when ground temperatures drop below 32°F (0°C).</u></em>

<u>ANSWER:</u>
The correct option is A: They transport heat over long distances affecting the wind that blows over the land.
<u>EXPLANATION:</u>
- Ocean currents carry cool or warm water or currents over long distances thereby affecting the wind that blows over the place bringing about a change in the climate.
- When the ocean currents carry cool air, the warm wind gets displaced by the cool air and therefore the climate of the place becomes cold.
- When the ocean currents carry warm air or water, the climate of the place becomes warmer.
- By transporting hot or cold currents, the ocean currents affect the climatic conditions of land and so bring about a change of weather.
Answer:
P generation: 1 purple flower (AA) : 1 white flower (aa)
F1 generation: 4 purple flowers (Aa) : 0 white flowers
F2 generation: 3 purple flowers (AA, Aa) : 1 white flower
Explanation:
Assuming the parents are AA and aa, the allele for white flowers is recessive, so there needs to be two of them for the trait to be expressed. Thus, the capital A purple allele that the other parent contributes will mask that white allele and all the flowers will appear purple. However, all of the offspring are Aa now, so when they are crossed, there's a 25% chance that they'll both contribute the lowercase a allele that codes for white flowers. Remember that if both of them give the lowercase a allele then the offspring will be aa and appear white.
Butane, C₄H₁₀ will undergo only London dispersion forces when interacting with other molecules of the same kind.
London dispersion force:
- The weakest intermolecular force is called the London dispersion force.
- When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the resulting transient attractive attraction is known as the London dispersion force.
- There are instances when this force is referred to as an induced dipole-induced dipole attraction.
Butane molecules only exhibit London dispersion forces because they are non-polar and have a symmetrical distribution of electron density.
<u><em>Butane:</em></u>
- It is a covalent non-polar molecule. Every C-C and C-H bond is non-polar. This is because there is little or no electronegativity difference between C and C in C-C bonds and none between C and H in C-H bonds.
