An experiment was conducted to determine which type of fruit attracts the most fruit flies. Equal sized pieces of apple, pear, a

nd banana were placed in separate containers at different areas around the school. The containers allowed the fruit flies to enter, but the fruit flies were unable to escape. After one day, observations were made by the students. Which best describes an error the students made in the experiment? A) too many types of fruit were used B) fruit flies were unable to escape C) different areas around the school were used D) one day is not long enough for the experiment

Answer:

C

Explanation:

<em>The error that the student made was to place the containers for the different fruits in different areas around the school.</em>

In order to ensure that each contain receives the same treatment, they should have been placed in the same area around the school. Different areas around the school might have varied populations of fruit flies, hence, jeopardizing the result.

<u>The containers should have been subjected to the same conditions in order to ensure an unbiased outcome.</u>

The correct option is C.

Answer:

"DRY MIX"

Dependent responding (variable) X axis

Manipulated independent (variable) Y axis

The drinks is the dependent variable because it "responds" to the temperature and is "dependent" on the temperature. The temperature determines the drinks sold-but the drinks sold doesn't determine the temperature.

Sidana [21]

macrophage are immune system cells that patrol the blood and body tissues. when a macrophage finds a foreign invader, the macrophage ingests (takes in) the foreign invader and then chemically digests (breaks down) that foreign invader. to perform this frequent chemical digestion, macrophage have more than the average body cell is

Macrophages are immune system cells that are vital to the development of non-specific defense mechanisms that provide the first line of defense against pathogens. These large immune cells are present in nearly all tissues and actively remove dead and damaged cells, bacteria, cancerous cells, and cellular debris from the body.

What is Macrophages?

Macrophages are specialized cells that hunt for, engulf, and kill bacteria and other dangerous organisms. They can also activate other cells by releasing substances known as cytokines, which present antigens to T cells and start an inflammatory response.

Blood monocytes that leave the bloodstream to differentiate in various organs give rise to macrophages. Each macrophage population exhibits significant variety, which most likely reflects the level of specialization necessary for each tissue's environment.

What causes a sea and land breeze?
viktelen [127]

☁️ Answers ☁️

☁️ During the day, the sun heats up both the ocean surface and the land. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. ☁️

❤️

☁️ Land: The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind ☁️

☁️ Sea: A sea breeze is created when a low pressure forms over the coast. The sea has a greater heat capacity than land, meaning it requires more heat to change its temperature. Therefore, during the day, as the sun’s warm rays shine down on the earth, because of the difference in heat capacity, the land heats up faster than the sea. ☁️

Hope it helps.

Have a nice day noona!~  ̄▽ ̄❤️
