Endoplasmic reticulum is situated close to the nucleus and is involved
in protein synthesis. Rough ER has lysosomes around the edges.
Lysosomes - The cleaner of the cell. Small and numerous, increases
surface area and increases the rate at which waste products are removed
from the cell.
Chloroplasts - Made up of Grana, stacked up to increase surface area.
This allows more Chlorophyll to be made to increase the rate of
photosynthesis.
Nucleus - Information point of the cell</span>
The difference between the two students that we know of is that they used a different meter stick. So the difference would be best attributed to the different tools they used.
Note, this is quite a huge difference. It's likely that one of the sticks, or both, are quite defect.
Circulatory system.....circulates blood (a vital delivery system of oxygen) throughout the whole body when tissues need it the most and with a constant supply.
In homo sapiens(humans), males are the heterogametic sex meaning their sex chromosomes are not the same(=XY) while females are homogametic(=XX).
Sex linked traits or x linked traits are traits whose genes are present on the X chromosome. So if there is a recessive mutation in those genes, males will express that recessive trait. Basically males express everything that’s on their X chromosome because they only have 1, but females have 2 which helps “hide” the mutation and to not express the particular recessive trait.
That is why sex linked traits are more evident in males in the population and an example of that would be colorblindness.
Hope this helps:)
A. Ribosomes
Ribosomes bind mRNA and translate into a protein. They reside in the cytoplasm and bind to the endoplasmic reticulum.
