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.

Explanation:
A factory that has not followed pollution control standards has been operating in an area that did not have such a factory before. Plants that used to grow well are not doing well. Fish in a nearby river are dying at a higher rate than usual. Why?
A Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water rise.
B It hasn't rained enough and the plants aren't getting enough water.
C The factory has increased the temperature in the area.
D Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water become lower.
Answer:
D
Explanation:
If the pH levels are becoming low then the water and dirt becomes acidic killing fish and plants
What role does an earthworm play in the food web?
PLEASE ANSWERR
Answer:
Earthworms may seem gross, but they actually play an essential role in food chains and ecosystems. Earthworms are decomposers that break down and recycle the matter from dead plants and animals, as well as waste products, returning it back into the soil. This is how a compost pile works!

Answer: True
Explanation: The only hints of the former hind limbs are the vestiges of a pelvis and femur embedded in the body wall. One in 100,000 whales is estimated to have a slightly protruding stub of a hind limb.
The pattern of natural selection where BOTH of the extreme versions of a trait are more advantageous than the average, so a population evolves in both directions away from the average.
Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
Notice in the image of the plant that both oxygen and carbon dioxide enter and exit the plant. Using what you know about photosynthesis and cellular respiration, explain what is happening with regard to these two gases.
A) Unlike animals, plants use carbon dioxide in cellular respiration and produce oxygen.
B) Plants, as autotrophs, only undergo photosynthesis and both use and produce oxygen and carbon dioxide in this process.
C) Plants require oxygen for photosynthesis and produce carbon dioxide. Plants then use the carbon dioxide produced in cellular respiration, releasing oxygen as a byproduct.
D) Plants require carbon dioxide for photosynthesis and produce oxygen as a byproduct. Plants then use the oxygen released in cellular respiration, producing carbon dioxide as a byproduct.
Answer:
D
Explanation:
Plants first go through photosynthesis, using sunlight and carbon dioxide. This creates glucose. It then releases oxygen into the atmosphere as a byproduct. To convert the glucose into usable energy, the plant goes through cellular respiration, which converts oxygen and glucose into ATP.
Even though living things are made of carbon, carbon dioxide is poisonous to everything but plants. TRUE OR FALSE ?
Answer:
True, if inhaled in great amounts by other organisms
Explanation:
plants convert carbon dioxide into oxygen.
An oak tree can be a home for animals like squirrels, birds, etc. as well as provide oxygen for the environment. This is an example of a _____________: the role an organism plays in the environment.

Three friends were walking along a Beach in New England. They looked closely at the Sand and noticed it was made up of tiny particles of Rock. They had different ideas about where the Sand came from.
Answer:
the probability (assumptions)of where the sand came from by the three friends may be
a. the thought that the sand came from distant mountains and landforms.
b. the thought that the sand came from rocks on the ocean floor.”
c. he thought that the sand came from undersea mountains and sea floor formations.
the best answer to this is the first probability answer (a)the thought that the sand came from distant mountains and landforms.
it is very essential as a student to have an idea about weathering, erosion, deposition, and landforms. if students/ individuals can identify/recognize that sand on a beach may have come from distant mountains and landforms due to rock weathering , deposition or erosion.

explain how gas is compressed into liquid in a gas barrel
Explanation:
A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.
