Ayoung man was visiting his grandmother at her assisted living facility. when he got to her room at 8: 30 am, he
found she had passed away. the coroner evaluated her and checked her temperature, it was 82.7 degrees
fahrenheit. what can you infer about the time of death?
the grandmother died about 2: 00 am
the grandmother died at approximately 8: 30pm the night before.
the grandmother had died about 10: 30pm the night before
the grandmother had died at about 6: 30 am

D

Explanation:

I'm not sure if this is completly accurate because i only did Intro to Bio so far.

DO NOT FLAG ME if this is wrong cause everyone seems to be doing that lately.

The grandmother had died at about 6:30 am

Explanation:

Since corpse temperature can be obtained easily and quickly, therefore after death the body losses or gains heat progressively until it equalizes with that of the environmental medium.

The approximate rate of heat loss continues until the surrounding temperature is attained after which it remains stable.

In other to calculate hours of death, formula is:

Hours since death = 98.6 - corpse core temperature/1.5

Where 98.6 stands for normal body temperature represented in Fahrenheit degrees Corpse core temperature (as measured by the coroner) evaluated to be 82.7 degrees in Fahrenheit and 1.5 stands as the degree per hour factor depending on the surrounding environment factor.

Based on the above to determine time around death:

98.6 - 82.7/1.5 = 43.46 hours, approximately 43.5 hours.

Resulting in the best statement that infers "The grandmother had died at about 6:30am" prior to the young man's young man's  

D.

Natural selection is the differential survival and reproduction of individuals because of the differences in the phenotypic characteristics. It supports the fact that those organisms, which have phenotypic characteristic favorable to survive in the changing environment as compared to other organisms, and these traits will also be passed to the successive generations.

In the given situation, the hummingbirds those have adapted according to the needs, that is deriving nectar from either from short and long tubes nectar. Therefore, two phenotypic characteristics like short beak and long beaks will become dominant trait in the population of humingbirds as the intermediate beak hummingbirds will not be able to feed from either of the flowers.

Therefore, option D. Hummingbirds with shorter or longer beaks can feed from one of the available orchids, but hummingbirds with intermediate beak lengths cannot feed from either is correct.
