Answer: a. Identical twins who grew up together are essential for these studies so that we can see if environment is really an influence or not. Maybe it could be a different case for each one of them. So by comparing them we can know.
b. The results of inherited variation would be that the offsprings would get the same type of characteristics from their parents while environmental variation is variation causedby the environment like heat, temperature, etc.
Explanation:
Answer:
ai) P= Red blood cell Q= Alveoli
ii)1. It gives the lungs a large surface area to volume ratio.
2. It is moist and thin.
b) P has a disc or biconcave shape which allows the O2 to bind to it with the help of a protein called haemoglobin for it to be transferred to various parts of the body.
c) Carbon monoxide will bind to the haemoglobin to form carboxyhaemoglobin causing oxygen disruption
The vegetation is present in all parts of the field if it is left uncut for many years.
If a field has been left uncut for a year, the vegetation will grow to its highest point. But if the field is left uncut for five years and then in ten years, all the field is covered with dense vegetation including different types of plants.
The plants will grow and turn into shrub if they are not cut down. After 10 years the field looks like a forest with dense vegetative cover so we can conclude that all the field covered with vegetation if it is left uncut for many years.

D) yes because in order to inherent a recessive trait you would have to have two recessive genes. In this case it’s (gg)
E)Yes because the parents have the genes (Hh) and (hh). (I’m assuming based off the first question) Therefore, if an offspring has hanging earlobes there’s a 50% chance they’d have the genes (Hh)
Experimenting. Experimenting is used in all three main branches of science, physics, chemistry, and biology, and is used in all the sub-branches of science, like marine biology, to make discoveries. Without experimenting, all we know about science would be random guesses.
