Answer:
a) We need to find p(x<68.15)
Standardize x to z, we have, z = (68.15-μ)/σ
=(68.15-57)/8.1
=1.38
Reading from standard normal tables,
p(z<1.38) =0.9162.
b) We need to find p(x>54.4)
Standardize x to z, we have, z = (54.4-μ)/σ
=(54.4-57)/8.1
=-0.32
Reading from standard normal tables,
p(z>-0.32) = 0.6255
Answer: The answer is A) The species eat different foods.
The size of their beaks determine what type of foods they eat.
The Nucleus stores the genetic information, the Lysosome breaks down macro-molecules, the Mitochondrion converts chemical fuel, the Ribosome synthesizes proteins and the Smooth ER serves as site of lipid synthesis.
The image for the question have been attached below.
- The cell structures which needed to be match to its descriptions are Nucleus, Lysosome, Mitochondrion, Ribosome and Smooth ER.
The correct descriptions are as follows:
- The <u>Nucleus</u> is the cell structures that stores the genetic information of the cell.
- The <u>Lysosomes</u> is the cell structures that breaks down macro-molecules using digestive enzymes.
- The <u>Mitochondrion</u> is the cell structures that converts chemical fuel into packets of chemical energy that can power the cell.
- The <u>Ribosome</u> is the cell structures that works with mRNA to synthesize proteins.
- The <u>Smooth ER</u> is the cell structures which serves as the site of lipid synthesis.
