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 %
Answer:
Why are embryos used in medical research?
Stem cells can be obtained at the early stages of embryo development; these cells are called human embryonic stem cells (hESC). They also could be used in research to develop drugs to treat serious diseases, or to repair organs following a stroke or heart attack.
I believe it would be manual labor. During the Industrial Age of Employment, most people would have to do repetitive jobs, or manual labor. Design, engineer, and knowledge broker were not common during this time.
Answer:
Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.
