Love is in the air

We agreed to be volunteers in an experiment because we felt the research was important

By passing on its chemical information in a cell, an animal is able to pass on its characteristics to the next generation.  

The animal’s babies survived the winter by hiding underground. 

We rely on our internal biological structure to protect us against disease.

Despite many studies, scientists have yet to find evidence that the condition can be inherited. 

Many species of bird stay with the same partner for their whole adult lives. 

The liver is an internal body part that is capable of regenerating itself to some extent. 

An important academic article recently showed that we share more of our DNA with reptiles than we once thought.  

Our __________________ protect us from catching diseases.

Scientists are looking for human __________________ to take part in trials for a new drug.

All animals pass on their __________________ in their DNA.

Many songbirds lay their batch of eggs in nests in April, and their ___________hatch soon after.

Human beings have to attract __________________ in order to pass on their characteristics just as other mammals have to do.

Mammals seek __________________ in order to have babies and continue the species. 

Scientists think the fossil is ten million years old, but very little __________________ has been found so far to prove this theory.

Our __________________ are inherited from our parents, and determine our appearance, health and character.

Researchers have published a number of important __________________ on the subject of inherited diseases, which you really should read.

Thanks to people who have donated their __________________ after death, we are able to carry out heart, lung and liver transplants.
