gcse bio: why do boys have a higher energy consumption than girls?

bigger surface area as well

Girls also dont like microbes as they enter there body and may invade body cells by binding to a corresponding receptor eg the cd4 on a thelper cell and then inserting there nucleic acid, next intergrse and reverse transcriptase will allow the nucleic acid to be interted into the host genome. Here it hijacks the cell and produced multiple coppied of itsself which are then assembled, bud out of the cell and spread to new ones where this process is repeated.

So yea girls dont like alot of things.

Im not too sure but i will have a go using what i know about this.

If you take your full couse then it will kill off more of the unmutated ones which then leaves your body free to fight off the mutates ones on there own.

If you stop taking them before you finish you may have lots of unmutated ones left which the body must deal with ontop of the new mutated ones.

20% of body energy is consumed by brain and as boys use their brain much more often than girls they have higher energy consumption

not compared to our body size though

thread starter said


proportionally our brain has same size :P

Hes saying that if 2 people are the same size then there brains will also be around the same size

Boys have more muscle therefore a higher BMR (Basil metabolic rate - the energy consumption at rest for body processes) since muscle is living tissue. Girls have higher body fat therefore are more insulated and so require less energy to maintain body temp.

Boys generally do more manual work therefore requiring more energy.

Basil? That is a herb! Are you sure you meant basil?

lol it was a typo, i meant basal metabolic rate - the energy consumption of your body at rest used for body processes
