Answer:

In addition to storing water, the reservoirs behind each of these 500 barriers also trap sand that used to be carried to the shoreline. Dams now withhold sediment from about 16,000 square miles of the state's coastal watersheds and have reduced the flow of sand by 25%, or about 3.6 million cubic yards each year.

Protein synthesis can be compared to building a doghouse. Sondra wanted to build a doghouse and found a book in the reference se

Nimfa-mama [501]

The correct answer is mRNA.

mRNA or messenger RNA is synthesized during the process of transcription, from DNA molecule which is used as a template. mRNA contains information about protein synthesis (translation) in the form of nucleotide triplets or codons.

In the example above: reference book is DNA molecule (template for copies), copies are mRNA, wood is amino acids (building blocks) and doghouse is protein.

An earthquake is best described as a Short term Long term Global Climatic

SCORPION-xisa [38]

I would say A) Short-term. Unless the earthquake is extremely powerful it would not be classified in the other three categories, so most earthquakes would be short-term

How do scorpio reproduce

krok68 [10]

Answer:

Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female's body, where the embryos are nourished in utero for periods varying from several months to a year.

In the example below the scientific method is used to solve an everyday problem. Match each component to the appropriate step in

joja [24]

Answer:

1. My toaster doesn't toast my bread. --> Observation

2. Why doesn't my toaster work? ---> ask questions

3. There is something wrong with the electrical outlet. ---> Hypothesis

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it. ---> Prediction

5. I plug my coffeemaker into the outlet. ---> Experiments

6. My coffeemaker works. ---> Result of experiment

Note: The question is missing some parts. The complete question is given below.

In the example below the scientific method is used to solve an everyday problem. Match each component to the appropriate step in the scientific method:

1. My toaster doesn't toast my bread.

2. Why doesn't my toaster work?

3. There is something wrong with the electrical outlet

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it.

5. I plug my coffeemaker into the outlet.

6. My coffeemaker works.

Explanation:

The scientific method involves the following; observations, ask questions, form a hypothesis, make predictions, design experiment to test the hypothesis, obtain results, analyze results, draw conclusions.

1. My toaster doesn't toast my bread is an observation made by the person.

2. The person then proceeds to asks questions based on the observation; Why doesn't my toaster work?

3. The next step involves making a hypothesis to try to explain the observation; "There is something wrong with the electrical outlet"

4. A prediction is then made, which is an expected outcome if the hypothesis is correct; "If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it".

5. Next, an experiment is conducted to test the hypothesis whether it is true or not; "I plug my coffeemaker into the outlet".

6. Results are obtained from the experiment which in this case is, "My coffeemaker works". The result is then analyzed to see whether it supports the initial hypothesis or not. Depending on the results, new hypothesis is made and further experiments conducted until a conclusion is reached.
