Answer:

The organism closest to the coral snake is organism 3, followed by organism 1 and finally organism 2.

Explanation:

The more similar the DNA composition of the organisms, the closer and more closely related they are. With that we can say that the coral snake is closer to organism 3, since the sequence of nitrogenous bases in its DNA is more similar, in relation to other organisms. After organism 3, it is organism 1 that most resembles a coral snake. Organism 2, however, has a different DNA composition, the organism being less similar and the more distant from the coral snake.

Pleaaase help , and show work if you can
charle [14.2K]

Answer:

1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable

Step-by-step explanation:

1. Available energy

Energy consumed              = 1000 J

Less waste         = - 177 J

Less respiration = <u>-784 J </u>

Total energy lost                = <u>-961 J </u>

Available energy                =   39 J

2. Percent of total energy usable

The chipmunk could use only 39 J of the original 1000 J.

% of energy usable = 39 J/1000 J × 100 % = 3.9 %

3. Percent of energy unusable

The chipmunk lost 961 J of the original 1000 J.

% of energy unusable = 961 J/1000 J × 100 % = 96.1 %
