Two or more kinds of alkenes (a type of monomer) can combine to form a polymers. Alkenes are a smaller kind of molecule that are joined through covalent bonds to form polymers (a larger molecule) and produce a different kind of substance.
To create polyester two different kinds of monomers called ETHENE and PROPENE are needed to make double bonds in the chemical reaction.
The rocks are in dry climate.
The relative permanence or “toughness” of the rock prone to weathering absolutely depends partially on sort of rock it is. This is because rock type is defined by the structure and relationship of the constituent metals, and complex metals vary in how they endure up to weathering.
Several types of rock, like granite, are very repellent to weathering. Moreover, Igneous rocks serve to heat slowly because it is difficult for water to penetrate into them.
Answer:
speed=distance÷time
2m/s,1.5m/s,1.25m/s,0.5m/s
Explanation:
speed=distance÷time
20/10=2m/s
30/20=1.5m/s
50/40=1.25m/s
30/60=0.5m/s
They did not observe any liposomal (vesicular) transport and the experiment didn't work because they were missing a compound referred to as motor protein.
<h3>What is Motor protein?</h3>
This type of protein falls under the category of molecular motors which have the ability to move in the cytoplasm of cells. This is done by the conversion of chemical energy into mechanical work which is aided by the hydrolysis of ATP which serves as the energy currency of cells.
We were told that the microtubules were spontaneously lengthening and shortening but there was no liposomal transport which means there were no molecular motors to fuel the process when the experiment was performed.
This was because of a lack of motor protein which would have aided the movement of the liposomes which therefore explains the reason why it was chosen as the most appropriate choice.
