Answer:
suppose x and y are two divided
parts of 4500. then
x+y=4500 __ (1)
given
5% of x = 10% of y
100
5x
=
100
10y
x=2y
2y+y=4500
3y=4500
y=1500
x+1500=4500
x=4500−1500
x=3000
hence the 4500 is been divided into
two parts of 1500 and 3000.

trophic level pertains to the position of an organism in the food chain. Humans
are the mos dominant organism that belong
to more than one trophic level. When we eat plants we become the primary consumers
but when we eat meat we can become the secondary or the tertiary consumers.
Birds are also organisms that belong to more than one trophic level. When birds
eat seeds they become the primary consumer, but when they eat insects they
become the secondary or even the tertiary consumers. </span>
Answer:
Phospholipids
Explanation:
The plasma membrane has a lipid bilayer in which proteins are embedded. The chemical composition of phospholipids of the membrane greatly influences the fluidity of the membrane. The length and saturation of lipid tails affect membrane fluidity. Phospholipids with short lipid tails having less than 16 carbon atoms increase the membrane fluidity as compared to the phospholipids with long tails. Phospholipids with saturated fatty acid tails make the membrane rigid while the ones with cis unsaturated fatty acid tails increase the membrane fluidity by their less dense packing.
A single-celled prokaryotic organism that is generally free-living and of few micrometers in length is bacteria. They are very small in size that cannot be seen without a microscope.
bacteria will be present in 100 milliliters of water.
<h3>How to calculate the number of bacteria?</h3>
Given,
- 1 milliliter = 1,500,000 bacteria
- 100 milliliter = ?
Therefore, option E is correct.
