I think it's A hope that's right
1) Colonial organisms require large areas with resources to sustain the entire colony, just as colonial people do. They are unable to grow in places that are sufficient to sustain a small number of organisms and if their population becomes to large, the colony collapses on itself. This is all visible in people as well.
2) Colonial organisms have greater safety due to their large numbers; however, unlike individual organisms, they are unable to sustain themselves with a smaller number of resources and migrating from one area to another is also more difficult for them.
3) A multicellular organism is more mobile and able to perform more functions in a better manner; however, this also leads to greater energy requirements than that of a single celled organism.<span />
Answer:
Explanation:
Protein deeply embedded in the bilayer are called integral membrane proteins. Most of this integral membrane proteins span the whole bilayer and they are called Transmembrane protein.
Because many molecules and ions can not pass through the hydrophobic core of the cell membrane they need a carrier mediated transport to go in and out of the cell. Transmembrane protein serves as channels, receptors (hormones, growth factors, neurotransmitter), tissue specific antigens, ion channels, membrane based enzymes etc that moves in and out of the cell.
Answer:
White dwarfs have an extremely small surface area to radiate this heat from, so they cool gradually, remaining hot for a long time.
Explanation:
As a white dwarf cools, its surface temperature decreases, the radiation which it emits reddens, and its luminosity decreases.
