Answer:

The ice form of water is most dense, and the vapor form of water is the least dense.

Explanation:

The molecular cohesion in ice is stronger than in liquid or vapor, forcing the molecules of water to remain closely bonded making it dense. The vapor form of water is weaker that liquid and ice since the molecules are nearly free roaming or loosely bonded making it not very dense.

Cheers.

Difference in prophase one and prophase two in meiosis

Dmitrij [34]

Answer:

The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes

During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.

In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If a red-eyed heterozygous f

ladessa [460]

The answer is Rr and rr.

We know:
r - recessive allele
R - dominant allele
RR - dominant homozygote with red eyes
Rr - heterozygote with red eyes (since one dominant allele R can mask recessive allele r)
rr - recessive homozygote with sepia eyes

Heterozygote Rr can give to the offspring either dominant allele R or recessive allele r. Recessive homozygote rr can give to the offspring only recessive allele r (take a look at the uploaded image of Punnett square).
After crossing the parents:
Parents: Rr x rr
Offspring: Rr rr Rr rr

So:
2 out of 4 offspring will be with heterozygous with red eyes Rr: 2/4 = 0.5 = 50%
2 out of 4 offspring will be with homozygous with sepia eyes rr: 2/4 = 0.5 = 50%

Describe any major landmarks (buildings, bridges, historical sites, etc.) that were destroyed during the earthquake.

Mkey [24]

Here we will discuss Damage to infrastructure in the 2010 Haiti earthquake.

Toussaint Louverture International Airport:

If we talk about the focus point of the Haiti earthquake that hit the Haiti on 12th january, 2010, then it was around 6 miles away from Toussaint Louverture International Airport.

Since the center was so near to airport that is why airport suffered from alot of damage. The control tower of the airport was almost completely destroyed due to which any radio communication became impossible. There was heavy power outrage due to damage caused to the power lines and due to this lightening system of the airport was completely shutdown. was damaged. However, the taxiways, runways and apron parts of the airport were operational at even that time of crisis.

Due to immense amount of damaged caused to Toussaint Louverture International Airport, all the relief bringing planes were diverted to other airports of the city.

The reconstruction and rehabilitation of the airport was started during 2010. It included the restoration and renovation of arrival and departure halls that were previously completely devastated. The renovation os falls included installation 16 new stations and three large baggage carousels and in the immigration room, There was also a significant explansion in the custom rooms.

However, the damage caused to Toussaint Louverture International Airport dur to 2010 Haiti earthquake is still considered as the destruction of major landmark due to earthquake.

Hope it helps!
