1. = <u>Surface</u><u> </u><u>area</u>
Volume
= <u>(</u><u>2</u><u> </u><u>*</u><u> </u><u>1</u><u>)</u><u> </u><u>m</u><u>²</u>
(1*2*0.5) m³
= 2 m-1 (the negative 1 is an exponent).
2. for elephant,
= S/V
= 25/10
= 2.5 m-1
for pigeon,
= S/V
= 0.5/0.05
= 10 m-1
Pigeon has the larger surface area to volume ratio.
3.
= S/V
= <u>(</u><u>4</u><u>0</u><u> </u><u>*</u><u> </u><u>3</u><u>0</u><u>)</u><u>m</u><u>²</u><u> </u><u> </u><u> </u><u> </u>
(40*30*40) m³
= 0.025 m-1
4.
= S/V
= <u>(</u><u>4</u><u> </u><u>*</u><u> </u><u>6</u><u>)</u><u> </u><u>c</u><u>m</u><u>²</u>
(4*6*5) cm³
= 0.2 m-1
hope you understand. All the best!

<span> answer: poor regulation of the brain's locus </span><span>ceruleus may lead to panic attacks</span>.
Locus ceruleus is a nucleus in the pons involved with physiological responses to stress and panic. When there is stress he responds by increasing norepinephrine (NE) secretion, which is a critical
regulator of numerous activities from stress response. Panic attacks result from alterations to NE.
the radiations that are used to treat cancers are of the gamma type. primarily emitted from cobalt-60 (a radioactive isotope). and it is more controlled than other radiation exposures. i.e. solar radiation which is not controlled.
hope that this helps.
