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.

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.

Answer:

TYPE OF DIET

Explanation:

Independent variable of an experiment is that variable that is subject to manipulation or changing by the experimenter in order to effect a response in the dependent variable.

According to the experiment in this question, the type of diet is changed for different groups of tadpoles in order to see the effect on their average weight. Based on this, the independent/manipulated variable is the TYPE OF DIET administered to each group of tadpole while the growth (average weight) of the tadpoles is the dependent variable.

Answer:

Assimilation

Explanation:

This is how plants absorb nitrates from their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll.

Answer:

Scientists always look for new questions to investigate.

Explanation:

Every scientific investigation begins with an observed problem, which in turn leads to a scientific question. This scientific question is the basis of the scientific method that leads to new discoveries.

In this question, barometers were once the best way to predict that a hurricane was coming. However, in recent times, hurricanes are now tracked using satellite photography. This new discovery about studying hurricanes is as a result of new questions that emerged. The new scientific questions, which are testable, led to a change in how scientists study hurricanes indicate.

Answer:

The chloroplast

Explanation:

It makes sugars that feed cell's machinery

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.

Answer:

Organism

Explanation:

The organism level of organization is the level of organisation that comes after the organ system level of organisation. The organism level of organisation is the level at which the living system is complete and comprises of the interconnection and synergy of the lower organization levels.

At the organism or life form organizational level, all the characteristics of living things are manifested.

The basic living system, a functional grouping of the lower-level components, including at least one cell.

Answer: B. Protein

Explanation: biuret solution is a chemical which is used to test for the presence of protein in any substance and it turns purple when protein is present.

Answer:

I guess its Ecosystem!!!!!

The basic energy source is Adenosine triphosphate that are formed in mitochondria.

Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy energy to operate the cell's biochemical reactions (mitochondrion, singular).

Adenosine triphosphate, abbreviated ATP, is a chemical compound that cells use to store and deliver energy. All types of cells use ATP as their primary energy source.

Thus, the basic source of cell's energy is ATP.

Answer:

Weird.. My answer was both of them were close. Huh.

Explanation:

Answer:

All is in order.......

stimulus is a thing or event that evokes a specific functional reaction in an organ or tissue.

homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.

Irritability is that characteristic of living organisms in being aware of, and being able to respond to, a stimulus which tends to disturb the steady state or homeostasis which all organisms prefer for maintaining life.

Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

Explanation:

to convert solar energy into chemical energy and then store that chemical energy for future use.

In nature, mutation rates aren't usually high enough to maintain alleles that are not favored in a population by natural selection.

While in the wild, many populations are led by natural selection. This means that favorable traits are passed down through generations, while unfavorable traits are not. Traits that are best suited for the environment of the organism will prevail to help the chance of survival.

Mutation rates usually aren't high enough to create traits that are unfavorable to an organism. While mutations are still possible, it is still unlikely. The traits that are chosen by natural selection are most likely to be passed onto organisms and their offspring.

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.

Explanation:

Answer:

Group A

Explanation:

Answer:

C. Group A

Explanation:

First, let's define accuracy and precision.

Precision: the measurements are all close to each other

Accuracy: the measurements are close to the true value.

Let's examine the answer choices.

A. Group C: 32.1 g, 35.0 g, 25.0 g

This is not accurate or precise. The measurements are far from each other and only one is close to 25 g.

B. Group D: 20.0 g, 25.0 g, 30.0 g,

The measurements are relatively accurate and precise. They are within 5.0 grams of each other and the true value.

C. Group A: 28.5 g, 28.4 g, 28.5

The measurements are the most precise. They are all within 0.1 gram of each other. They are also somewhat accurate.

D. Group B: 25.5 g, 25.0 g, 24.8 g

The measurements are not precise or accurate. There is one measurement that is far from the true value and the other measurements.

Therefore, the most precise measurements are from Group A.

Answer:

Drug action.

Explanation:

Drug action can be defined, in short, as the action of the drug on the body. The effects of almost all drugs are a consequence of their interaction with macrocellular components of the body. These interactions modify the function of the relevant component and thereby initiate the biochemical and physiological changes that characterize the response or reaction to the drug. Receptors are cellular structures that have a specific purpose and that are activated in their action by different substances.

Answer:

Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow and eventually spread through the body (metastasize) through continuous mitotic division. Thus, cancer cells are more sensitive to inhibition of mitosis than normal cells.
