Multi cellular organism is an organism that consists of many cells unlike unicellular which consists of a single cell.
The first picture is of multicellular organisms.
The second, for more information, is of unicellular organisms
Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.
From smallest to largest the levels of ecosystem organization are:
Organism
Population
Community
Ecosystem
Answer:
If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.
Nine amino acids are needed to travel through the thickness of the membrane.
Alpha-axial helix's distance between amino acids is 1.5. A
The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.
Therefore, the helix's length is (21 X 1.5) = 31.5.
One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A
The thickness of the membrane is determined by the formula above to be 31.5 AA.
In the beta-strand, there is 3.5 AA between each amino acid.
Therefore, (31.5/3.5) = 9 amino acids are needed.
