Consider the following story:
“During the summers when Xavier was a young boy (around 8 years old), his grandfather would take him to northern Ontario to go fishing on weekends. Shortly after his grandfather died his family left Ontario. He was never able to clearly remember the fishing trips. When he was 30 years old he moved back to Ontario with his wife. One weekend they decided to take a trip to northern Ontario to spend the weekend at a resort on one of Ontario’s many lakes. When they got out of the car, they were overwhelmed by the aromatic smell of the trees in the heavily wooded area by the lake. Suddenly, memories of the wonderful weekend fishing trips with his grandfather came flooding back to the him.”
Discuss the following questions:
Is this an example of a repressed memory? If not, why not?
If it’s not a repressed memory, then what is it? What accounts for the sudden re-emergence of this buried memory?
Could this account for other, more traumatic, kinds of “repression” as well?
Answer:
No.
Explanation:
This is not an example of a repressed memory because these are the good memories whereas the repressed memory are bad memories of childhood. It may be infantile amnesia due to the inability of adults to bring episodic memories memories of situations or events that occurs in their childhood. The sudden re-emergence of this buried memory is the experience of the same situation or place or event that occurs in the childhood. If a person visit to a same place which he gone in their childhood so the person remember the buried memory.

what is HIV in full
Answer:
Human Immunodeficiency viruses
HIV Overview
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
There is currently no effective cure. Once people get HIV, they have it for life.
But with proper medical care, HIV can be controlled. People with HIV who get effective HIV treatment can live long, healthy lives and protect their partners.
History of HIV
HIV infection in humans came from a type of chimpanzee in Central Africa.
The chimpanzee version of the virus (called simian immunodeficiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood.
Studies show that HIV may have jumped from chimpanzees to humans as far back as the late 1800s.
Over decades, HIV slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid to late 1970s.
To learn more about the history of HIV in the United States and CDC’s response to the epidemic, see CDC’s HIV and AIDS Timeline.
How do I know if I have HIV?
The only way to know for sure whether you have HIV is to get tested. Knowing your HIV status helps you make healthy decisions to prevent getting or transmitting HIV.
Are there symptoms?
Graphic listing symptoms of HIV: Fever,HIV Symptoms and Testing, Chills, Rash, Night sweats, Muscle aches, Sore throat, Fatigue, Swollen lymph nodes, and Mouth ulcers.
Some people have flu-like symptoms within 2 to 4 weeks after infection (called acute HIV infection). These symptoms may last for a few days or several weeks. Possible symptoms include
Fever,
Chills,
Rash,
Night sweats,
Muscle aches,
Sore throat,
Fatigue,
Swollen lymph nodes, and
Mouth ulcers.
But some people may not feel sick during acute HIV infection. These symptoms don’t mean you have HIV. Other illnesses can cause these same symptoms.
See a health care provider if you have these symptoms and think you may have been exposed to HIV. Getting tested for HIV is the only way to know for sure.
What are the stages of HIV?
When people with HIV don’t get treatment, they typically progress through three stages. But HIV medicine can slow or prevent progression of the disease. With the advancements in treatment, progression to Stage 3 is less common today than in the early days of HIV.
Stage 1: Acute HIV Infection
Stage 1: Acute HIV Infection
People have a large amount of HIV in their blood. They are very contagious.
Some people have flu-like symptoms. This is the body’s natural response to infection.
But some people may not feel sick right away or at all.
If you have flu-like symptoms and think you may have been exposed to HIV, seek medical care and ask for a test to diagnose acute infection.
Only antigen/antibody tests or nucleic acid tests (NATs) can diagnose acute infection.
Stage 2: Chronic HIV Infection
Stage 2: Chronic HIV Infection
This stage is also called asymptomatic HIV infection or clinical latency.
HIV is still active but reproduces at very low levels.
People may not have any symptoms or get sick during this phase.
Without taking HIV medicine, this period may last a decade or longer, but some may progress faster.
People can transmit HIV in this phase.
At the end of this phase, the amount of HIV in the blood (called viral load) goes up and the CD4 cell count goes down. The person may have symptoms as the virus levels increase in the body, and the person moves into Stage 3.
People who take HIV medicine as prescribed may never move into Stage 3.
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
People with AIDS have such badly damaged immune systems that they get an increasing number of severe illnesses, called opportunistic infections.
People receive an AIDS diagnosis when their CD4 cell count drops below 200 cells/mm, or if they develop certain opportunistic infections.
People with AIDS can have a high viral load and be very infectious.
Without treatment, people with AIDS typically survive about three years.

In this phase the sister chromatids line up on the _______ plate through a push and pull motion as they connect to the microtubule spindle fibers emanating from the ________. The third phase of Mitosis is________ . In this phase the________ (sister chromatids or homologous chromosomes) are pulled apart. The fourth phase of Mitosis is_______ . In this phase the nuclear ________starts to reform and the DNA de-condenses.
MITOSIS:
This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc. PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME. ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles. The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

Chewing of food is not a chemical process in the digestive system, but a mechanical process. Therefore, the correct option is D.
What is Digestive system?A collection of organs called the digestive system help break down food into smaller molecules that the body can absorb and use for energy, growth, and repair. It consists of anatomical organs such as the anus, esophagus, stomach, small and large intestine, liver, and pancreas. Food is broken down physically and chemically by the digestive system, which also absorbs nutrients and gets rid of waste.
Chemical process of digestive system involves Bile interacting with digested food in the small intestine, acids reacting with food particles in the stomach and saliva breaking down food particles while the mechanical process involves chewing of food.

What process formed this delta?
Select one:
-A:erosion and deposition
-B :condensation and precipitation
-C:rock layer deformation
-D: shifting tectonic plates
Answer:
I think A
Explanation:
because erosion is the washing away of soil
Erosion and deposition are the formed on this delta. Thus, the correct option is A.
What is Erosion and deposition?Erosion is the action of the surface processes such as water flow or wind which removes the soil, rock, or dissolved materials from one location on the Earth's crust and then transports it to another location on the Earth's crust where it is deposited. The erosion is distinct from that of weathering that involves no movement.
Deposition is the laying down of the sediment carried out through the wind, flowing water, the sea or ice. Sediment on the Earth's crust can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by the organic activity such as sea shells or by evaporation.
Therefore, the correct option is A.

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?
Answer:
Immunization is one of the most effective processes of preventing or treating dangerous disease. It should be told and advertise to the general public about the facts and importance of vaccination. Doctors and government should explain the reports and ratio that the people who are taking the vaccination in the proper dose and the right amount of vaccination are about 9 timeless likely to have to the other people. It is essential to get a proper dose and proper amount to avoid the development of resistance.
There are several forms of vaccine and they have a different schedule from each other. Every vaccine is safe but one needs to know the cycles, dose and amount of the vaccine. Yes, we should spread out the inoculation schedule to prevent confusion of a young person.

When two parents heterozygous for genes for curly hair are crossed, what percent of their offspring would have curly hair? What percent would have straight hair?
Answer:
75% curly
25% straight
Explanation:
When two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.
What do you mean by Heterozygous?Heterozygous may be defined as the presence of two different alleles at a particular locus. It always includes one normal allele and one mutated allele.
Here, the allele for curly hair is dominant over the allele for straight hair. So, the offspring who carry the pure dominant and heterozygous alleles for curly hair would have the phenotype of curly hair, while the offspring who carry both the recessive allele would have the phenotype of straight hair.
Therefore, when two parents' heterozygous for genes for curly hair are crossed, 75% of their offspring would have curly hair, while 25% of their offspring would have straight hair.
