It seems that you have missed the given options for this question, but anyway, here is the answer. We are constantly bombarded by a variety of stimuli inside and outside of our bodies but we are not overwhelmed by sensory information because a<span> very tiny percentage of incoming sensory information is received by the cerebral cortex. Hope this helps.</span>
Land animals require more energy since they have to overcome greater inertia during locomotion. Land mammals have adopted many evolutionary mechanisms to support high energy demand.
Heart is four chambered instead of the usual two in aquatic animals like fishes. More number of divisions in heart increases the efficiency of blood circulation process which in turn increases the oxygen delivery rate to cells for producing more energy.
Land mammals also have developed lungs which increase the efficiency of gas exchange process which increases the output of respiration process.
In addition, land mammals also have a strong and developed musculoskeletal system which helps in locomotion.
If only 50% of weight genes are transferred as seen in 0.5 probability then the ideal weight will be 14 grams (9 grams from first and 5 grams from the 2nd and so... ). But due to the genetic anomalies the range should be taken as 13-15 grams with a confidence interval of 95%...
