Answer:
1) cortical epithelial cells; (2) macrophages and dendritic cells
Explanation:
T cells, also known as T lymphocytes, are a fundamental type of cell of the immune system that determines the specificity of the immune response to specific foreign particles (antigens). T cells are produced in the Thymus (it is for that reason that they are called T cells) and then circulate throughout the bloodstream in order to recognize specific antigens in association with major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells (APC), such as macrophages and dendritic cells. T cells undergo positive and negative selection: 1- positive T-cell selection refers to the process by which T cells bind cortical epithelial cells that express Class I or Class II MHC molecules with enough affinity to get a survival signal; whereas negative selection occurs when T cells bind to macrophages and dendritic cells that express MHC specific receptors with a strong enough affinity to get an apoptosis (programmed cell death) signal.

Answer:
Si bien la Copa América y la Eurocopa son dos competencias internacionales de fútbol a nivel continental, en donde los equipos nacionales de cada continente se enfrentan para determinar quién es el mejor de su región, lo cierto es que existen claras diferencias entre ambas competencias.
Por un lado, en lo organizativo y de marketing, la Eurocopa tiene una mejor organización a nivel espectáculo, atrayendo mayores audiencias dada su mejor estructura y formato de mercado. Es decir, el producto de la Eurocopa es más atractivo que el de la Copa América.
Por otro lado, a nivel juego, la Eurocopa también lleva la ventaja, dado que, salvo casos muy puntuales como Messi o Neymar, la enorme mayoría de las estrellas del fútbol juegan en selecciones europeas.

Write letters to the editor of the local newspaper about a lack of full-service grocery stores.
Answer:
Write letters to the editor of the local newspaper about a lack of full-service grocery stores.
Explanation:
Food security is a situation where people in a certain region or country have enough food to eat. Not only does food security mean statistically sufficient food production, but food security must be stable and accessible to all.
Food security is an important issue in Third World countries, where hunger and malnutrition are widespread. In most cases, the main reasons for this have been political decisions and economic changes that have deprived locals of the opportunity to run a traditional subsistence economy and fail to provide for food security. This has happened, for example, to many indigenous peoples in the Amazon, whose living environment has been invaded by large landowners and international corporations.
In this context, letters making known the lack of certain food supply services is one way in which young people can contribute to this issue.

After eating a healthy meal with your family, you are helping to clean up the leftovers. In order to prevent foodborne illnesses, you want to properly store the leftovers.
Which food safety storage procedures should you follow? Select two options.
Place leftovers that you intend to eat seven days from now into the refrigerator.
Discard any food left out at room temperature for more than two hours.
Place food into containers and immediately put them in the refrigerator or freezer.
Put leftover food on plates directly into the refrigerator.
Throw the leftover food in the trash right away, as it is no longer safe to eat.
Answer:
Discard any food left out at room temperature for more than two hours.
Place food into containers and immediately put them in the refrigerator or freezer.
Explanation:
The FDA recommends the 2-hour rule to prevent people from getting bacteria that grow on the food within that time period (if longer). This can lead to illnesses.
Once you're done eating, it is safe for you to put the food into containers so that bacteria cannot be grown on them. But you should be wary, the containers might be a bit of a problem if the food is too hot or if it's not cleaned well.
"Place leftovers that you intend to eat seven days from now into the refrigerator." This is an unhealthy decision because it can lead to bacteria growing on the food within that time, this also goes with "Put leftover food on plates directly into the refrigerator."
"Throw the leftover food in the trash right away, as it is no longer safe to eat." This is not always the case because sometimes the food might've been out for only just half an hour (or any time less than 2 hours).
Answer:
Discard any food left out at room temperature for more than two hours.
Place food into containers and immediately put them in the refrigerator or freezer.

Which of the following will best reduce your chance of contracting HIV?
A. Using condoms during each and every kind of sexual encounter
B. Keeping your sexual partners to only two or three different people
C. Encouraging your friends and family members to get tested for HIV
D. Learning as much as you can about the history of HIV and AIDS
Answer:
A
Explanation:
using condoms reduce the chances of transmission of fluids
Using condoms during each and every kind of sexual encounter is the best way to reduce your chance of contracting HIV. Hence option A is correct.
What are condoms?Condoms are a type of barrier contraceptive that can be used to prevent pregnancy and the transmission of sexually transmitted infections (STIs), including HIV.
They are typically made of latex or polyurethane and are worn over the male organ during sexual intercourse to prevent semen, vaginal fluids, or blood from coming into contact with the partner's genitals or mouth.
Condoms act as a barrier between the bodily fluids that can transmit HIV, such as blood, semen, vaginal fluids, and breast milk. Using a condom every time you have sex, whether it's vaginal, or oral, greatly reduces the risk of contracting HIV or other sexually transmitted infections (STIs).
It's important to use condoms consistently and correctly to get the maximum protection.
While keeping your sexual partners to a small number, encouraging others to get tested, and learning about HIV and AIDS are also important in preventing the spread of HIV, using condoms during sexual activity is the most effective way to reduce the risk of contracting the virus.
