What is acid rain? What chemicals make rain acidic, and how does it happen?
How does acid rain affect humans? Are there any health problems associated with acid rain?
What effect does acid rain have on trees and soil?
What happens when lakes and aquatic systems become acidic?
Are the aquatic systems in our area being affected by acid rain? If yes, to what extent?
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. It can have harmful effects on plants, aquatic animals, and infrastructure.
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe.
Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
Answer:
When rain water has a lower pH(acidic) than usual it is considered acid rain.
Rain water becomes acidic when sulfur dioxide and nitrogen oxides are released into the atmosphere. They cause a chemical reaction with water, oxygen, and other chemical in the atmosphere to form sulfuric and nitric acids which then mix with water and fall down as rain.
Acid rain causes air pollution which can cause respiratory diseases. This can cause difficulty in breathing. Acid rain causes asthma, chronic bronchitis and pneumonia.
Acid rain removes nutrient from the soil, trees need these in order to be healthy. It separates aluminum from the soil which destroy plant root tips, this makes it difficult for trees to take up water.
Acid rain reduces the pH of water in aquatic systems which is harmful to marine animals. It kills many fish and other creatures that fish eat. It separates aluminum from the soil which drains into water system. The aluminium is toxic to fish in acid waters. It causes damage to the gill which effects the respiratory system of the fish and the fish dies.
Acid rain is affecting most of the places on earth.

Why are viruses considered to be nonliving?
A. They have no genetic material.
B. They cannot reproduce without a host cell.
C. They do not respond to their environment.'
D. They cannot use energy.
Answer:
B. They cannot reproduce without a host cell.
It is considered to be nonliving as it cannot reproduce on its own.
Explanation:
Without a host cell they are unable to reproduce as it does not have the necessary reproductive tools.
It reproduces by using the host cell's reproductive tools by taking control of it.
Viruses also don't need energy as living organisms do. So the answer may be D. as well.
Viruses are considered to be non-living because they cannot reproduce without a host cell.
WHAT ARE VIRUSES?Viruses are organisms that are incapable of reproducing without a living host.
Viruses can only make use of the mechanism of a living host, which they infect.
Viruses are structurally made up of a genetic material and a protein capsule.

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Answer:
The options to this question are:
A) allele
B) codon
C) nucleotide
D) chromosome
The answer is A) allele
Explanation:
RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.
However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).

A____fossil is evidence of an organism, but is not made of the organism itself
A. coprolite
B. trace
C. record
D. index
Answer:
ttrace
Explanation:
A trace fossil is evidence of an organism, but is not made of the organism itself.
What is Trace fossil?The structure and behaviors of an organism, rather than its physical form, are used to classify trace fossils. A few of the trace fossils discovered in Denali have been connected to body fossils discovered in rocks from the North Slope or Talkeetna Mountains that are of a comparable age.
These connections provide investigators access to identities that are more certain than those known solely from trace fossils.
Bird tracks near probe marks in the earth suggest that the birds were using their beaks to dig for food. Invertebrate burrows located in the same rocks possibly provide the answer to what good food the birds were eating.
Therefore, A trace fossil is evidence of an organism, but is not made of the organism itself.

What effect will the settling of sediment have on the shape of the stream?
The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
Answer:
Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?
Answer:
The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

Sometimes, distinguishing the type of interaction between species in not straightforward. Remoras are fish that are often found attached to larger animals, such as sharks. The relationship between remoras and sharks is often described as a commensalism. Although this suggests that sharks do not benefit from this relationship, remoras sometimes consume parasites on their skin. Which of the statements below best supports the relationship being a commensalism?
Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Although remoras consume parasites, they usually consume the flesh of the shark itself and harm it.
Remoras consume parasites, but sharks depend on parasites to remain healthy.
The fact that remoras consume parasites suggests that they provide a benefit, making this a commensal relationship.
Answer:
The commensal relationship between the sharks and remoras can be described as although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Explanation:
A commensal relationship refers to a relationship where two or more organisms in a habitat neither benefit or harm each other.
The second option infers that the remoras harm the sharks. This is a parasitic relationship.The third option infers that the sharks are harmed by the remoras because the sharks depend on something that the remoras are limiting. This is also a parasitic relationship.The fourth option infers a commensal relationship, but falsely describes it. The relationship described by this option is a parasitic relationship (one benefits, the other does not).Therefore, the answer is the first option: Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Answer:
it is A) Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.
Explanation:
