Identify the tectonic plate boundaries.
Andreyy89

Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.

<h3>Difference between Divergent and convergent boundaries </h3>

Divergent boundaries are the regions where new crust is formed when the plates pull away from each other while on the other hand, Convergent boundaries are the regions where crust is destroyed when one plate dives over another.

So we can conclude that Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.

The boiling point of an aqueous solution is 101.02 °C. What is the freezing point?
kompoz [17]
Colligative properties calculations are used for this type of problem. Calculations are as follows:

ΔT(boiling point) = 101.02 °C - 100.0 °C= 1.02 °C
<span>ΔT(boiling point)  = (Kb)m
</span>m =  1.02 °C / 0.512 °C kg / mol
<span>m = 1.99 mol / kg

</span><span>ΔT(freezing point)  = (Kf)m
</span>ΔT(freezing point)  = 1.86 °C kg / mol (<span>1.99 mol / kg)
</span>ΔT(freezing point)  = 3.70 <span>°C
</span>Tf - T = 3.70 <span>°C
T = -3.70 </span><span>°C</span>

An oil company located a area of oil sands and began an analysis of two possible extraction methods. The oil is heavy oil, makin
Rus_ich [418]
The cost for CHOPS is in the sand and the extraction of the oil from sand.
The cost for SAGD is the generation of steam.
The benefit for CHOPS is the low cost.
The benefit for SAGD is high extraction efficiency.
The other factors that could affect the decision are fuel cost and the required purity of the oil.

When a sample of purified phospholipids is mixed with water, spherical structures called liposomes form.
lutik1710 [3]

Answer:

B). The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.

C) The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.

E) The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar

Explanation:

A liposome is simply a tiny bubble also referred to as vesicle that is gotten from the same material as the one a cell membrane is made from. It should be noted that liposomes can be filled with drugs, and then used in the delivery of drugs for diseases such as cancer etc.

Phospholipids afford fluidity, permeability and stability to neural membranes. They're also vital for proper functioning of the receptors, integral membrane proteins, and the ion channels.

The characteristics of phospholipids that enable liposomes to form in water are:

• The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.

• The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.

• The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar
