Explanation:
Immune response Evidence points to the fact that this early microbial colonization helps our body to defend itself against disease.
Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.

Phosphorus in soil is transformed into insoluble compounds unless what happens?
Answer:
It is not absorb by the plants, it turns into insoluble form.
Explanation:
Phosphorus in soil is transformed into insoluble compounds unless not used by the plants. The insoluble phosphorus is transform into soluble form in the soil by phosphorus solubilizing bacteria. The phosphorus solubilizing bacteria helps in conversion of insoluble phosphorus into soluble phosphorus which can absorb by the plants. If the phosphorus is not absorb by the plants and present for a long time, it can be converted into insoluble form which is unavailable for the plants which can be converted back with the help of phosphorus solubilizing bacteria.
Which cell replicates via meiosis?(1 point)
sperm cell
heart cell
skin cell
red blood cell
thanks!!
Answer:
Sperm cell
Explanation:
Because it is a reproductive cell and in one of the stages of foetus growth is meiosis so this cell undergoes meiosis to pass that stage
Meiosis is the process by which cells divide into four haploid daughter cells.Sperms are the cells that replicates via meiosis. Option A is correct.
Meiosis:
It is the process by which cells divide into four haploid daughter cells.
The daughter cells contains half of its parents chromosomes.The daughter cells are genetically different from the parent cells.It is occur in the germ cells of the organisms to produce gametes like sperm and ovum.Therefore, sperms are the cells that replicates via meiosis.

How does air pressure affect
breathing?
Answer:
When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.
Answer:
The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate. This is because air moves from high pressure areas to low pressure areas. During bad weather and at high altitudes the air pressure is lower, making it harder for us to breathe.

3. Si sales de tu casa y recorres 5 metros de distancia. ¿A qué distancia te
desplazaste?
Answer:
5 metros.
Explicación:
Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.

Explanation:
how would the solar eclipse be different if the moon was moved AWAY from the earth?
Answer:
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

Answer:
1) As soon as the paper cuts into the cells of your skin, your body springs into action. First, blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.
The process is called Blood clotting.
2) The cell that are made will have the same same amount of DNA/chromosomes.
3) Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

The earth is __blank__This trend most closely follows trends in the Earth's __blank__ Within the Earth's __blank__the component that is likely most responsible __blank__
Complete question:
Fill in the blanks.
The earth is ______ (warming, cooling, static, dynamic). This trend most closely follows trends in the Earth's ______ (albedo, distance from the sun, energy input from the sun, atmosphere). Within the Earth's ______ (albedo, mantle, atmosphere, crust) the component that is likely most responsible ______ (carbon dioxide, magma, water, humans).
Answer:
The earth is warming. This trend most closely follows trends in the Earth's atmosphere. Within the Earth's atmosphere is the component that is likely most responsible for carbon dioxide.
Explanation:
Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth. The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.
The current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.
The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole Earth´s history. It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities.

Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.Complete the chart. Thymine _____, Guanine ____.
Answer: 27, 23
Explanation: Thymine goes with Adenine and together they equal 50 so Thymine would be 27 because Adenine is 23. Same with Cytosine and Guanine. They go together and equal 50 so Guanine would be 23 because Cytosine is 27. Hope this helps!
