To measure the diameter of a organelle with a scale line of 1 µm.
- Measure the length of the scale line on the micrograph in mm, e.g. 1 µm = 17mm.
- Measure the diameter of the organelle in millimetres, e.g. = 60mm.
- True diameter of organelle.
<h3>How do you find the actual size of an organelle?</h3>
To calculate the actual size of a magnified specimen, the equation is simply Mixed6 :
Actual = Image size (with ruler) ÷ Magnification.
Thus, this is how we can measure the size of an organelle.

Answer:
E. Nucleus
Explanation:
All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.
The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:
EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.
Answer:
b
Explanation:
this is correct bc it shows that although a mutation occurred, it happened over time, and so now, the lizards attained a new adaption which allows them to avoid the floods
Hope this helps!
The study of the chemical reactions that take place in all living organisms is called Biochemistry
