In therapeutic cloning, the embryo has the same genes as the patient

In therapeutic cloning, does the embryo have the same genes as the patient? 

The function of an enzyme is to break down large food molecules into smaller soluble molecules

The reduction of blood flow caused by coronary heart disease results in a lack of oxygen to the heart muscle 

Why is the reduction of blood flow due to coronary heart disease a problem? 

A malignant tumour is a tumour which is commonly known as cancer and invades and spreads to other parts of the body through blood 

Capillaries are the blood vessel with a single cell wall for efficient diffusion

Which blood vessel has a single cell wall for efficient diffusion?

A stem cell is an undifferentiated cell; this means they can turn into any other cells 

You can find and extract human stem cells from embryos and bone marrow 

Where can you extract/find human stem cells? 

In plants, stem cells are found in the meristem 

What part of the plant are stem cells found? 

In humans, stem cells can be used for treating paralysis and diabetes 

In humans, what can stem cells be used for? 

In therapeutic cloning, the embryo has the same genes as the patient so there is no rejection of the cells

Why does the embryo have the same genes as the patient in therapeutic cloning? 

The name of the theory that describes how enzymes work is the 'Lock and Key Theory' 

What is the name of the theory that describes how enzymes work?

What is the colour change if starch (carbs) is present? 

If proteins are present, the colour will change from blue to purple 

What is the colour change if proteins are present? 

The bottom two chambers of the heart are called the ventricles

What are the bottom two chambers of the heart called? 

The role of the pacemaker cells in the heart is to control the natural resting heart rate

What is the role of the pacemaker cells in the heart? 

In the heart, the pacemaker cells can be found in the right atrium 

Where do you find the pacemaker cells in the heart? 

The left ventricle pumps blood to the heart

Which chamber of the heart (exact) pumps blood to the heart? 

Blood enters the heart from the rest of the body through the vena cava

Which vein does blood enter the heart from the rest of the body? 

The 4 components of blood are red blood cells, white blood cells, platelets, and plasma

4 substances transported by blood are carbon dioxide, urea, soluble products (digestion), and hormones 

What are 4 substances that are transported by blood?
