B. It is a small pilot study on non-AWAR species.
C. It is a teaching activity that uses students' personally owned dogs and cats.
D. There are no circumstances in which animal work may begin before IACUC approval.
Answer: the correct option is D (There are no circumstances in which animal work may begin before IACUC approval)
Explanation:
The IACUC known as Institutional Animal Care and Use Committees is a local working group that research facilities must appoint in accordance with the Animal Welfare Act , Policy on Human Care and Use of Laboratory Animals. It was introduced to research system by the U.S. government in 1986. The policy protects all warm-blooded animals except rats, mice, and birds bred for research. For an institution to use a specie that is covered by the policy, it must obtain their approval before work begins. I hope this helps. Thanks.
Answer:
All of the above are true.
Explanation:
Microbial cells are surrounded by the plasma membrane or cytoplasmic membrane. It serves as a selective barrier allowing materials in and out of the cell e.g. allowing nutrients in and waste out.
Microbial cells grow independently, in that they are unicellular, and so do not depend on the other cells to carry out the process. However, they rely on nutrients, and in some environments, these may be nutrients produced by other organisms.
Microbial cells are unicellular, although some microorganisms are multi-cellular. Microorganisms such as bacteria are unicellular, that is, exist as single cells.
Bacteria and viruses are microorganisms.
Answer:
Lever and wedge
Explanation:
You use a lever to add strength and the tip of the shovel is a wedge.
It is not an issue of color, but rather of sugar content that causes the ants to choose the blue sugar over the red sugar. Because the blue sugar contains more sugar than the redsugar, the ants preferred it.
All sweet carbohydrates can be referred to as sugar, however the phrase is most frequently used to refer to table sugar, also known as sucrose, or a “double sugar.” Carbohydrates are converted by the body into easily absorbed simple sugars like glucose. There are numerous varieties of sugar.
The body uses sugars and starches from carbs to feed the brain with glucose and give the rest of the body's cells energy.
Most plants have sugars in their tissues. Honey and fruit are plentiful natural sources of simple sugars.
Sugarcane and sugar beet are particularly high in sucrose concentration, making them perfect for effective commercial extraction to produce refined sugar.
Therefore, blue sugar contains more sugar than the red sugar

Explanation:
The ants choosing the blue sugar over the red sugar isn't a matter of color, but it'd a matter of sugar content.
The ants chose the blue sugar because it has more sugar content than the red sugar.

The answer is; true
These microbes are usually adapted to their environment and this is why they are found in virtually all ecosystems. You will find bacteria even at the bottom of deep ocean beds deep and in geothermal vents, hypersaline water and very cold regions (such as polar regions). Fungi which vary widely in size from microscopically small to the largest organisms such as mushrooms are also found in virtually all environments on earth. They are nonetheless different species of these groups adapted to their environments.
