Answer:
The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of <u>molecules moving a little farther apart.</u>
Explanation:
The kinetic-molecular theory explains the changes of state in the following way: When a solid is heated, its particles increase their kinetic energy, so that the vibration becomes more and more intense until, having reached the melting temperature, they become so weak that the particles acquire freedom of movement, that is, if we increase the temperature of a solid material system, its molecules will move faster and the average distance between them will increase, the cohesion forces decrease and there will come a time when these forces are incapable to keep the molecules in fixed positions, the molecules can move.
Membrane, ER, cytoplasm, ribosomes, Golgi complex, cytoskeleton
Answer:
This will happen in 39 years.
Explanation:
The population of the birds varies as A = A.e^kt
The population of birds fell from 1400 from 1000
Time it will take for the population to fall below 100 = x years.
when t = 0, population = 1400
t= 3; Population = 1000
Therefore:
1400 = 1000e^5k
e^5k= 1400/1000
k= (In 1.4)/5
we need to find x, such that
1400/1000= (e^xk)
14=(e^xk)
In(14) =kx
x= 5In(14)/In(1.4)
x= 39 years
Answer:
C
Explanation:
Eukaryotic cells have membrane-bound organelles that allow for compartmentalization. Prokaryotic cell do not share this feature.
These two apply.
1.) The sporophyte of seed plants is photosynthetically independent.
2.) In seed plants, dispersed spores contain a multicellular gametophyte.
