Answer:
Depending on the food pyramid, on the side there may be something that says decomposers. These eat from all of the sections of the pyramid.
Energy flows from the bottom to the top, and then to the side with the decomposer.
Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid. Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.
<span>Gene
expression is taking place when chromatin is less condensed. Highly compacted
chromatin is not accessible to the enzymes involved in DNA transcription,
replication and repair because transcription is being inhibited or inactive. Therefore,
looser configuration permits transcription or gene expression to take place. </span>
Answer:
Sheep Brain:
Sheep brain is smaller in size the human brain. The convolutions or folds are absent in sheep brain. Olfacory bulb is more developed in shhep's brain as compared to human brain. Sheep brain is more elongated in shape.
Human brain:
Human brain is large in size. The convolutions are more numerous in human brain. Human's brain olfactory bulb is less developed as compared with sheep's brain. Human brain is round in shape.
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 %
