Eyepiece magnification(EM) X Objective magnification (OM)= Overall Magnification:
Answers
Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
TM = x40
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
TM = x100
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
TM = x400
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
TM = x1000

Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

(Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time. Tiktaalik roseae was a unique organism that has been nicknamed the “fishapod” because it is believed to be a species had traits of both fish and tetrapods, the first four-legged animals.)
Which evidence would scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae?
-using transitional forms
-using relative dating
-studying decreasing complexity
-studying analogous structures
Answers
Answer:
A. using transitional forms
Explanation:
On Edge 2020
Using transitional forms is the evidence scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae.
What is Transitional forms?This is referred as the remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group.

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea
Answers
Answer: He performed dihybrid crosses
Explanation:
Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.
Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answers
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
