2. Regarding Phases 2 or 3 of the experiment, if more or fewer drops of Reagent D (sodium hydroxide) were needed to get the same

blue color as in Phase 1, what does this tell us about the quality of the water when yeast was consuming nutrients in the water? Did something similar to eutrophication occur?

Answer:

The water quality is deteriorated as there is depletion in Oxygen O₂.

Yes, the activity of the yeast has precluded the usage of the water

Explanation:

Here, we note that the addition of more or fewer drops of Reagent D sodium hydroxide (NaOH) is required to get the same blue color as in Phase 1 where no yeast is added indicates the level of O₂ in the water as the amount of O₂ concentration in the solution is directly proportional to the amount of Reagent D required to reach blue, meaning the O₂ is depleted.

When less sodium hydroxide is required to turn blue we have depleted sodium hydroxide in the solution that is the yeast added in Phases 2 or 3 of the experiment, consume O₂

Eutrophication is the enrichment of a body of water with nutrients that results in a change in the ecosystem such as: algae production, oxygen depletion and other results that diminishes the water usage.

If the sensory neurons in a person's hand could not carry a transmission of a signal, such person will not be able to feel anything that he or she touches.

<h3>What is the significance of sensory neurons?</h3>

Sensory neurons are referred to or considered as such neurons which are helpful in transmission of signals from the sensory organs to the nervous system. Skin is one of the essential sensory neuron present in the hands.

If the hands are not able to transmit signals, then the sensory neurons will not be able to give messages to the nervous system, and as a result, one will not be able to feel anything that he or she touches.

Therefore, the significance of sensory neurons has been aforementioned.

Make sure you don't just copy and paste it. Have a good day!!

What is the name of the law?

The Manage our Wolves Act was introduced at 09/12/2018 its last action 11/26/2018.  

What level of government passed it?

The Federal Government

What is the purpose of the law?

The purpose of this law is to “address the protection of the gray wolf (Canis lupus) under the Endangered Species Act of 1973. Specifically, the Department of the Interior must issue a rule to remove the gray wolf in the contiguous 48 states from the list of endangered or threatened species and reinstate a rule that removed the gray wolf in the Western Great Lakes region from the list. The bill exempts those rules from judicial review as well as a rule that removed the gray wolf in Wyoming from the list.” (Sorry i didn’t know how to like paraphrase something like that)

What steps of the lawmaking process did it go through?

On 09/12/2018 it was first Introduced in the House. On, 11/09/2018 Reported by the Committee on Natural Resources. On, 11/16/2018 this law was Passed/agreed to in the House.  

What did people who supported the law say? What did critics say?

The people that supported it were very keen on it because grey wolves have been becoming an increasing problem to ranchers in the past years by eating their livestock. However,the critics say that it will put this species back on the endangered Species Act within a very short period of time.

How could this law affect common Americans?

It will make the tension between the animal environmental groups and the farmers even more muddy and it will also change hunting permits for the grey wolf.

How could this law affect other levels of government?

It may cause states to consider changing its hunting laws or its hunting permit.

If i were a legislator or other government official at the time the law was still a bill under debate i would have voted against this bill because i don’t agree with the idea of being able to hunt and kill grey wolves who have just reached steady numbers by giving people the access to do that may be catastrophic it may  undo all the work the the Endangered Species act is trying to do and i believe that in a few very shorts years these beautiful animals will end up back on The Endangered species list.

What restrictions do you think should be placed on studies with animal participants? Explain
Tju [1.3M]

Examples of restrictions placed on studies with animal participation include: setting a cap on the amount of time the animal can “work”, provide realistic temporary home environments, ensuring consistent nourishment in the form of food and water on a time scale, allowance for social interaction with other animals, ensuring the experience is harmless, and following regulations set by the Animal Welfare Act (ACA)/ People for the Ethical Treatment of Animals (PETA)/ or another animal care and safety organization.

These restriction examples can help to ensure the health, happiness, and safety of participating animals.
