Sickle cell disease causes hemoglobin to be in the wrong shape, this causes

• undergo translation

• the whole cell to be misshapen

• the cell to divide

• mutate

What is the function of red blood cells?

• transport oxygen to cells and CO2 back to lungs

• protect blood from invading pathogens

• take messages from one part of the body to another

• secrete digestive enzymes to break old organelles down

The sickle cell mutation originally evolved as a beneficial adaptation against what disease?

• mad cow disease

• avian bird flu

• malaria carried by mosquitos

• Covid-19

Only inheriting the sickle cell gene from one parent will

• cause most red blood cells to be misshapen

• result in no red blood cells having the sickle cell shape

• still provide protection against malaria while most red blood cell function normally

Inheriting the gene from both parents results in

• sickle cell disease

• possible problems in multiple organs due rbcs getting stuck in vessels

• sickled cells having a shorter life span

• all answers

Human blood is ALWAYS red, NEVER any other color.

• True

• False

Cells in the tissues of your body need oxygen for cellular respiration to make ATP for cellular processes or they DIE... Hemoglobin needs iron as part of its structure to transport oxygen to tissues inside red blood cells. What do you think happens if you don't get enough iron in your diet?

• Enhanced oxygen transport to tissues and better aerobic function

• Reduced risk of anemia and fatigue
• Increased energy levels and improved immune function due to increased carbon dioxide levels.

• Iron-deficiency anemia can occur, leading to fatigue, weakness, and decreased immune function.

Not every animal has red blood. Spiders, lobsters and snails have blue blood due to the presence of the protein haemocyanin which contains copper.

• True

• Not False
