the diagram shows two cells found in human blood.
a. the actual diagram of
red blood cell is 0.007mm ( 7 um) in diameter.
Calculate the magnification of the diagram. show your working.
side note: I measured it in a ruler and it's 2.3 cm = 23 mm (drawn to scale)
Answers
a)
Actual diameter = 0.007 mm
Diameter of scaled diagram = 2.3 cm = 23 mm
Formula to use:
Magnification = scaled dimension/actual dimension
Magnification = 23/0.007
Magnification = 3285.714... → x3286
b)
Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose
c)
i.
RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs
ii.
RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;
The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;
The small size also helps in being able to circulate the vasculature effectively and successfully

The effect of pH on a certain enzyme is shown in the graph. At what pH would the enzyme be most effective?
Answers
Answer:
2
Explanation:
The enzyme will be the most effective between 8 and 10
The enzyme will show maximum activity in the range of pH between 8 and 10. This can be the enzyme's optimum pH as at this range it is found to be most effective. Thus, the correct option is 2.
What are enzymes?Enzymes are the biocatalysts. They act as enzymes in the biochemical reactions by reducing the activation energy required by the reactants to form products. Enzymes remain unused in a reaction.
Enzyme activity depends upon different factors which include temperature, pressure, pH, etc. Enzymes show maximum activity at the optimum conditions of these environmental factors.
From the given graph, it can be interpreted that the enzyme shows maximum rate of action between the pH range of 8 and 10. Thus, this is the optimum range of pH.
Therefore, the correct option is 2.

The diploid phase of the life cycle begins with the formation of the zygote.
Meiosis is referred to the type of cell division which occurs in the production
of male and female sex cells. This also occurs during sexual reproduction.
Parent cells provide male and sex cells such as sperm and egg which
contains DNA. They then fuse together to form a zygote which is the diploid
phase as a result of the fusion of two haploid cells. The zygote then
continues to undergo some meiotic processes which reduces it to back to a
haploid cell and consequent growth to form a fetus.

There are different cells with different sizes, shapes, and forms.
Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera.
Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function.

Question 5 options:

Half the distance on the path traveling back down.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
Answers
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The Correct choice is ~
" At the top of the swing where it briefly stops before changing direction "
before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~
The answer is D - At the top of the swing where it briefly stops before changing direction. This is where potential energy is at its highest, meaning that kinetic energy is at its lowest. When the pendulum is beginning its upwards swing, it has a lot of kinetic energy. When it is half the distance traveling down it also has lots kinetic energy. When it is at the bottom it as well has a lot of kinetic energy. The only time where the kinetic energy is least is when the pendulum stops to change direction. Any form of stopping forced the object to loose its kinetic energy.
