Laughingcat is probably right. I think this is more like a upper block science topic on adaptation.

Study the table below.


Q1. What is the relationship between the number of eggs laid by an animal and the amount of care given to the eggs?

Q2 Why is there a need for the cod and the common tree frog to lay so many eggs?

:?: :?:

My cheeky boy's reply...... :rotflmao:

A1. Too many eggs freak out the parents because too tired to look after. Too many eggs will lead to sibiling rivary and hence cause parents to have headaches.


Mummy's analysis......pls correct me if i am wrong eh.....

A1. Eggs that are bigger take a longer time to develop and hence requires parental care.

No offence plum-cake. My answer is still the same. Throw the book into the dust bin.

I don't know what are the answers in that book, but I came across answers like : Water helps to support the weight of the huge body, big space allows the big animal to survive because 70% of earth is covered by water, abundance of food, huge body of mammal generates heat and water helps to cool down .... All these are hypotheses. They have not been proven as no detailed study has been done. Therefore, we cannot bluff our kids and tell them things that have yet to be proven as fact.

The question as printed in that book is \"Why do the world largest animal live in water?
The word \"do\" implies that the answer is \"definitive\" i.e. confirmed. However, no one has actually confirmed any of those conclusions.

There would be no problem if the question had been phrased as \"What could be a possible reason for the world largest animal to live in water?\"

Science question cannot be tackled like comprehension. All questions must be phrased appropriately. If the answers are not definitive, then we must add words \" a possible reason/explanation...\"

Sorry again, as it sounds like my above comments were directed at you. No, no it is at the book. There are too many such books in the market where the writer doesn't even have slightest idea what \"scientific method\" is all about.
