<u>Answer</u>:
1. The purpose of the uninoculated control tubes used in the oxidation fermentation test is to serve as basis of the medium for the color comparison and that it is sterile.
2. It is necessary to use two controls in order to illustrate the no color change (green color) under both aerobic and anaerobic conditions.
3. The purpose of the experiment is to determine if the organisms utilize the carbohydrate and thus is fermentative. This will result in a color change from green to yellow.
Thus, the medium in one tube is sealed with a layer of paraffin to prevent diffusion of oxygen. This tube will show that the medium is unaffected by the lack of oxygen.
The second tube will allow the diffusion of oxygen. This tube will show that the medium does not change color naturally in the presence of oxygen. Thus, the color changes will be caused only by the fermentation process of the organisms.
Answer:
D. Hydropower can harm native aquatic populations.
Explanation:
- Hydropower is the power of water or hydrosphere and is the cheapest and simplest form of energy.
- The hydrosphere is a renewable source of energy and is thus non-polluting but most of the hydropower that is converted into electricity is harmful to the marine and aquatic life forms.
- As it disturbs their habitats and created chemical and physical change in the body of water. Such as depletion of oxygen and enrichment of nutrients.
They use a formula and that formula is
People/Land Area=Population Density
Answer:
That the adult has more cells than the baby?
Explanation:
Cells are the basic unit of structure and function in all living organisms. Which describes the GREATEST difference between the cells of a baby gorilla and the cells of an adult gorilla? The adult has more cells than the baby.
