Doctors often use certain medications to treat infections. A few people have a reaction to some of these medications, such as itching, swelling, or trouble breathing. This is an example of *
Answer:
Allergy
Explanation:
Allergy occurs when the body system reacts to the introduction of a foreign substance. The immune system plays an important role in the elimination of substances that are capable of causing harm to the body, substances that trigger an allergic reaction in the body is known as allergen.
When an allergen is introduced into the body, the immune system views it as an intruder that is capable of destroying various tissues and cells. It therefore manufactures antibodies to fight off the intruders thereby resulting in an allergic reaction.
Medications such as antibiotics can cause allergic reactions such as itching and swelling of the skin.
Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. What would happen to an ecosystem if this process was compromised?
A.
The population of green plants in the ecosystem would increase.
B.
There would be more energy available to consumers in the ecosystem.
C.
The soil quality of the ecosystem would dramatically improve.
D.
The carrying capacity of the ecosystem would be limited.
Answer: D
Explanation:
Since the Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. They end up playing a vital role in the ecosystem, if this were to be compromised nothing good would come form it Disease, competition, predator-prey interaction, resource use and the number of populations in an ecosystem all affect carrying capacity. If Earthworms, small insects, and microorganisms couldn't break down the the dead material and return it to the soil, then surely the carrying capacity would be drastically effected.

which bone layer holds calcium and other minerals
Answer:
In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. This process is carefully regulated by hormones and is discussed more completely in the section about hormones.

What significant negative effect on the environment cause by obtaining water from a well?
Answer:
Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health. Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain.
Explanation:
All water is a good part of the environment. ... If you mean can individuals keep getting water forever from their personal well and it has no effect on anyone else - no. It is not good in that respect. Wells are part of the local groundwater system and the water is usually not limited to one person's land.

What is it about the structure of the alveolar-capillary unit that makes diffusion possible? Select all that apply.The capillaries are large. The cell wall of the alveoli is thin. Many capillaries surround one alveoli sac. There is always low pressure in the alveolar-capillary unit. The alveolar-capillary unit provides a large surface area.
Answer:
The most successful option would be: Many capillaries surround a sac.
Explanation:
Although in this question, I wanted to tell you that among all the options that is the most correct, but it is incomplete.
The capillaries that are in the alveolar unit are not only in great numbers to ensure gas diffusion but they are also SINUSOID capillaries where the cells of these capillaries do not have tight cell junctions, and there is a micrespace between cell and cell that forms the capillary wall.
And why is this? Because the greater the permeability of the capillary, the better the process of gas homeostasis or gas exchange at the alveolar level will be favored.
I hope I have completed your question, because it is very important that you know this, they are not simple capillaries that are only increased in number, but their sinusoidal permeable form makes them fulfill a VITAL function for the human being, this does not mean that all the capillaries of the body are like this, do not forget that we are speaking on time of the socket.
Answer:
B. The cell wall of the alveoli is thin
E. The alveolar-capillary unit provides a large surface area
A father has blond hair. A mother has black hair. Their three offspring have brown hair, blond hair, and red hair, respectively. Which pattern of inheritance could account for human hair color? Explain your answer.
Answer:
polygenic inheritance
Explanation:
The pattern of inheritance that could account for human hair color according to the illustration is polygenic inheritance.
In polygenic inheritance, multiple alleles (the alternate versions of the same genes) controls the trait for hair color. Individuals that inherit different combinations of alleles from the same parents will have different hair colors.
In this case, there are alleles that determines blond hairs, black hairs, brown hairs, and red hairs. All these alleles are alternate versions of the same gene. The father could be carrying blond/brown alleles and the mother is carrying black/red alleles or vice versa, their offspring will exhibit different hair color depending on which allele is dominant or recessive.
Of the sites listed below, which one is the homo erectus site that provides the longest record of habitation
Answer:
Zhoukoudian
Explanation:
Zhoukoudian can be seen as a cave system which is found in suburban Fangshan District, Beijing in which It has yielded many archaeological discoveries, which include one of the first specimens of Homo erectus , dubbed Peking Man,as well as a fine assemblage of bones of the gigantic hyena Pachycrocuta brevirostris.
The cave was identified as Homo erectus and it said to have more than 10,000 pieces of stoneware, several cinder layers indicating fire use in early man, as well as animal fossils which are from 200 separate species.
Therefore Zhoukoudian is the homo erectus site that provides the longest record of habitation

Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.
Answer:
Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.
