MULTIPLE CHOICE QUESTIONWhat is the test variable (independent

variable) here?

The additive anti-barnacle treatment

The number of barnacles on the boat

The amount of paint applied to the boat

Answers

Answer 1

Answer:

The number of barnacles on the boat

Explanation:

The number of barnacles of the boat is an independent variable because an independent variable is that variable that can stand alone or does not

changee or has no variation due to dependent variable.

It is not affected by changes in dependent variable. It's changes does not depend on dependent variable.

The number of barnacles on the boat is an independent variable and it changes does not depend on The amount of paint applied to the boat and The additive anti-barnacle treatment.

Answer 2

Answer:

Final answer:

In the given question, the 'additive anti-barnacle treatment' applied to the boat is the independent variable. It can be manipulated to assess its effect on the number of barnacles on the boat.

Explanation:

In experimental research, an independent variable is the variable that is intentionally modified or manipulated by the researcher to observe the effect on the dependent variable. In this case, the test variable (or independent variable) you're inquiring about seems to be the 'additive anti-barnacle treatment' applied to the boat.

This variable is independently manipulated, because changes in its elements or levels (such as different types or amounts of treatment) might affect the dependent variable, which in this case could be the 'number of barnacles on the boat'.

A population of turtles was introduced to an island that is favorable for the turtles to inhabit. Describe what the population graph would look like for this turtle population over time and provide reasoning as to why the population would show this type of growth.

Answers

Answer:

The turtles would flourish in the ecosystem. The graph would be curved up and it would even out at the carrying capacity.

Explanation:

If the island is favorable for the turtles, that means that they will survive well and be able to reproduce and carry on the population. Of course, there is a limit to how much resources a population can have so it would even out eventually, making the graph show statistical growth.

Water is most likely to be condensing when we observe which of the following atmospheric conditions?. A. a heavy rainstorm.
B. a very cloudy sky.
C. a clear sky.
D. a light snow.

Answers

Answer: B. a very cloudy sky

Condensation is a process in which the gaseous form of water is converted into liquid. It is very important for the water cycle. This results in the formation of the clouds, fog and dew. For the occurrence of condensation, the air must be saturated. Saturation occurs most commonly when the warm air in the atmosphere cools down to it's dew point. The condensed water vapors and some of the particular matter forms the clouds.

Answer: B

Condensation is a process via which a liquid directly converts to a gaseous state, skipping the liquid state altogether. Therefore, a very cloudy sky is an example of water being converted to gaseous state directly.

Which was Ventor’s contribution to science? discovered the existence of single-celled A)organisms B)invented the light microscope C)discovered the structure of DNA D)invented a synthetic cell

Answers

The correct option is D.
Craig Venter contributed significantly toscience and humanity by inventing a synthetic cell. He accomplished this byconstructing the genome of a bacterium and by incorporating it into acell. The cell was made by joining together the genome of a pathogen from small stretches of DNA that are synthesized in the laboratory. The genome created was then inserted into an empty cytoplasm of a related bacterium. The pathogen use is called mycoplasma mycoides, it usually infect goats.The cell is the first synthetic life form in the world and it open theway for new types of research.

Venter's contribution to science was the invention of a synthetic cell. The correct option is D. Craig Venter created a synthetic cell which is totally controlled by man-made genetic instructions. This invention has opened the door for a lot of potential new research which can be carried out in the field of molecular biology.
