The scientific method is a
Answer:
The scientific method is a process for experimentation that is used to explore observations and answer questions.
Data Collection: Pinky’s science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder. Fun Fact: There are free “cricket chirp calculators” online you can explore, which didn’t exist freely online when Pinky was in junior high. Consider if data was collected consisting of the average number of cricket chirps at different temperatures in her backyard. 10. Which variable would be an independent variable?
Answer:
Different temperatures in her backyard
Explanation:
The independent variable would be the different temperatures in Pinky's backyard.
The independent variable is a variable whose value is not affected by another variable during research. It is a variable that directly affects the actual variable that is measured - the dependent variable. The independent variable is usually varied in order to see the kind of effect it will produce on the dependent variable.
In the case of Pinky, the different temperature at the backyard affects the number of cricket chirps. Hence, the temperature is considered the independent variable while the number of cricket chirp is considered the dependent variable.
The nucleolus __________. The nucleolus __________. assembles ribosomes synthesizes ATP stores chromatin synthesizes proteins
Answer:
The correct answer is: assembles ribosomes.
Explanation:
The nucleolus is the largest structure in the nucleus of a cell body, granular, and round structure. The nucleolus is made up of components like RNA and proteins In the center of the nucleus of a cell.
This is associated with the synthesis of ribosomes and the formation of the rRNA or ribosomal RNA. The ribosomal RNA and proteins combine together to form subunits of the ribosomes that are move out of the nucleus to the cytoplasm in order to perform their function.
Thus, the correct answer is: assembles ribosomes.
If two events are correlated, what must be true? (1 point)
O Both events have the same result.
O Both events have the same cause.
O The events tend to happen together.
O One event caused the other.
Answer:
Both events have the same cause.
Explanation:
Correlation in statistics refers to the measure of the relationship between two variables. Simply put, two variables are said to be correlated if a mutual relationship exists between them. This means that if two events correlates, a relationship in which, both events have the same cause, exists between them.
Correlation can be positive or negative depending on whether the increase of one event causes the other to increase (positive) i.e. they both move in a similar direction or the increase of one event causes the declination of the other (negative) i.e. they move in opposite directions.

Which resource does NOT need to be cycled by ecosystems because a continuous, unlimited supply is available?
Answer:
Solar energy
Explanation:
Solar energy is the resource that doesn’t need to be cycled by ecosystems because a continuous, unlimited supply is available.
The Sun provides the solar energy which is very important in plant’s food production and it isn’t dependent on the ecosystem and seasons. This is because the Sun provides light during the day and we experience daytime all year round. This is why the solar energy has a continuous, unlimited supply.

A scientific question that could be used to create an easily reproducible scientific experiment is Does sugar or salt have a greater effect on plant growth?
Thus option D is correct.
What is scientific experiment ?
Any process of measurement used and different test are carried to verify the hypothesis called as scientific experiment.
The hypothesis can be defined as the proposition from observation can either be true or false and from this an investigation can be developed.
From this hypothesis, the experiment can be designed for the discovery of something unknown.
The basic steps are followed in scientific experiment such as observation, asking question, formulation of hypothesis, set up of experiments, results and collection of data, conclusion, reporting results.
The scientific experiment have two most important factors like variable which is either dependent or independent variables.
Thus option D is correct.

You would expect high levels of blood glucose and the presence of glucose and ketones in Mr. Gutteman's urine if:
Answer:
The correct answer would be : Mr. Gutteman's pancreas is secreting too little insulin.
Explanation:
Insulin is a hormone produce by pancreas that maintain glucose level by using glucose for energy or to store for future use. Insulin prevent blood sugar level to go too high or too low.
Less production of this hormone cause high glucose level in blood that leads to glucose, ketone bodies in urine of a person.
Thus, the correct answer is : Mr. Gutteman's pancreas is secreting too little insulin.
A young child has recently been diagnosed with Pompe disease, which causes severe muscle weakness and muscle tone. The patient lacks the enzyme alpha-glucosidase (GAA). A lack of this enzyme leads to accumulation of the carbohydrate glycogen in muscle cells. Based on your knowledge of biological macromolecules, which argument best supports why this disease is occurring? Question 13 options: Glycogen is a protein and the enzyme, alpha-glucosidase, is not breaking it down into the lipid glucose. Glycogen is a protein and the enzyme, alpha-glucosidase, is not breaking it down into the nucleic acid glycerol . Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into its monomer, fatty acids and glycerol. Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into the monosaccharide glucose.
Answer:
Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into the monosaccharide glucose.
Explanation:
Pompe disease is an inheritable disorder that affects many parts of the body, especially the heart and other muscles.
People that are diagnosed with the disease present a defect in a gene called AAG. The enzyme alpha acid glucosidase is not present in the organism or it just does not work properly. These people have problems in processing the polysaccharide glycogen.
The AAG enzyme is located in the lysosomes, and its function is to decompose the polysaccharide glycogen (complex sugar) into the monosaccharide glucose (a simpler sugar). This last one is the source of energy of the organism.
The unproperly functioning of the enzyme causes the accumulation of glycogen in lysosomes of the macrophages.
