When you are rating evidence by its value, weigh the benefits of one good fingerprint versus hair and fiber evidence. Fully explain your answer

Answers

Answer: Conviction based on the support of the physical fingerprint is a more reliable evidence over hair and fiber evidences.

Explanation:

Physical fingerprint has more value than hair and fiber evidences. As no two fingers can have exactly alike fingerprints belonging to the same person. The fingerprints of two identical twins cannot be alike but DNA evidence obtained from hair, fiber, or any other biological evidences can show similarity. Thus physical fingerprint have more value over DNA fingerprint it can directly related to a suspect to whom it belongs to depending upon the uniqueness of the minutiae characteristics.

Explanation:

The stomach and small intestine produce different enzymes is gene codes for pepsin is expressed in the stomach but not expressed in small intestine.

What is the function of trypsin?

Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, the process of digestion that formed in the stomach.

Is a proteolytic enzyme produced by the pancreas in an inactive form called trypsinogen.

Thus, option "D" is correct as trypsin is expressed in stomach for protein breakdown.

Watch the seven minute video on the "Mystery of the Buffalo boom" on you tube. Write a reflection on how scientists used their reasoning skills to make a claim about causes of the "buffalo boom".

Answers

Answer:

In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals.  Food and predators.

First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.

Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.

As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.

Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.

In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.

Explanation:

In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.

We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.

How is your body temperature held constant despite different weather temperatures
outside?​

Answers

Answer:

Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.

Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

The immune system has both specific and nonspecific defenses against viral infections. Which statement describes a nonspecific response of the immune system in fighting viral infections?

A. T cells are produced to search out and destroy the viruses.
B. Memory B cells are activated to rapidly respond to the viral infection.
C. Plasma cells quickly replicate and release antibodies that bind to the viruses.
D. Virus-infected cells produce interferons that lead to the inhibition of viral replication

Answers

Answer:

C

Explanation:

I just did this same question

Virus-infected cells produce interferons that lead to the inhibition of viral replication and act as a nonspecific response of the immune system in fighting viral infections. Therefore, the correct statement is option D.

What are interferons?

The immune system has two types of responses to viral infections: specific and nonspecific. Interferons are signaling molecules produced by virus-infected cells to activate antiviral defenses, such as apoptosis in infected cells. This refers to the nonspecific response of the immune system in fighting viral infections

Interferons function by alerting the immune system about the presence of a viral infection. Interferons can also stimulate the production of other immune cells, such as natural killer cells and macrophages to eliminate the infected cells.

Interferons have been also used to treat viral infections, such as hepatitis B, and are the nonspecific defenses that act as a first line of defense against viral infections.

Therefore, interferons that lead to the inhibition of viral replication are the nonspecific response of the immune system in fighting viral infections.
