Answer: e. 2.5 ml
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 20X
= volume of stock solution = ?
= concentration of required solution= 1X
= volume of required solution= 50 ml
Thus 2.5 ml much of a 20X tricaine stock solution is needed to dilute in order to make your solution.
T-A-C-G-A-T because A and T pair and G and C pair
Considering the following statements;
A. It can exist without a constant source of energy input
B. It must contain consumers but can exist without producers.
C. It involves interactions between biotic and abiotic factors.
D. It can exist on land, but it cannot exist in lakes, rivers, or oceans.
The correct statement is C. that an ecosystem involves interactions between biotic and abiotic factors.
Biotic factors are the living things in an ecosytem, they include plants, animals, bacteria, fungi and others. Abiotic factors on the other hand, are the non-living factors in an ecosystem, they include water and air, sunlight, the amount precipitation in an ecosystem is also an example of abiotic factor. The two types of factors are crucial for an ecosystem to exist and thrive.

When the caterpillars enter the pupa stage of their development, their cocoons are plunged into boiling water. This kills the silkworms and begins to unravel the longer fibers.
