Answer: Survival rate up to start of April = 76.67%
Explanation: size of colony = 150mice.
Size of colony in February =125mice.
Size of colony in march = 115 mice.
1. Survivorship rate in February
= Size of colony / size in February *100.
= 122 / 150 * 100
= 83.33% to the nearest hundredth
2. Survivorship rate in march
= Size of colony / size in march *100.
= 115/150 * 100
= 76.67% to the nearest hundredth.
Answer:
(A) Bioaccumulation
Explanation:
When the concentration of certain substances in the bodies of the organisms of various trophic levels keeps on increasing as they pass through the food chain, the process is called bioaccumulation or biomagnification.
Most of the organic non-biodegradable pollutants/chemicals exhibit bioaccumulation. Being insoluble in water, these chemicals are accumulated in the fat tissues of the organisms.
As the predator feeds on the prey having a non-biodegradable chemical in its tissues, the chemical enters the body of the predator.
As these chemicals pass through the food chain, there is a gradual increase in their concentration stored in the living tissues of the organisms. Therefore, the top consumers exhibit maximum bioaccumulation of contaminants in a food chain.
<span>I believe the answer is,
High systolic, because when the heart pumps, the pressure inside the aorta would be greatest, causing the weak spot to rupture outward.
This indicates high blood pressure that causes rupture of the aorta or aorta dissection.</span>
Below are the choices that can be found elsewhere:
a.66 s
<span>b.68 s </span>
<span>c.70 s </span>
<span>d.78 s
</span>
<span>An outlier is a result that is abnormally too high or too low. Most of the results fall between 66 and 70, but 78 seems to be abnormal, so it's your outlier. The answer is D. Hope it helps :)</span>
