Answer: Nephrons

Explanation: The structural and functional unit of the kidney is known as nephrons. These are microscopic structures found in the kidneys.

A healthy adult has 0.8 to 1.5 million nephrons in the kidney of a adult. Its main function is filtration of the blood.

Blood is filtered and the impurities are collected to excrete out of the body in the form of urine.

Incomplete question. The remaining part of the question read;

Words in the left column:

Yes
No
Observational
Manipulative

1. A physiologist incubates eggs in the lab at a range of temperatures to see what temperatures produce males and what temperatures produce females.

2. A biologist predicts that shade might influence ground temperature, and therefore turtle sex ratios. He records the sex ratio of turtle hatchlings in shaded and unshaded regions

3. An ecologist predicts turtles grow larger when no predators are around. She places turtles in an experimental pond system where half the ponds have predators and half the ponds have had the predators removed.

4. A climatologist predicts that concentration of CO2 in a city will be negatively correlated with the amount of wind in that city. He collects data and looks at the amount of CO2 in a city as a function of the wind speed in the city.

5. A sociologist conducts a survey in Hawaii to describe people's attitudes about global climate change.

6. A scientist determines the average wind speed, and variation in the amount of wind, in a number of locations to see which locations would be most suitable for wind turbines

Answer/Explanation:

1. Hypothesis-driven? Yes!

Observational or Manipulative? Observational.

We can make this conclusion here that the physiologists' research is hypothesis-driven since we are told he wanted to "see what temperatures produce males and what temperatures produce females." In other words, he wanted to know whether the temperature used in incubators can influence the sex of an egg by means of observation.

2. Hypothesis-driven? Yes!

Observational or Manipulative? Observation.

3. Hypothesis-driven? Yes!

Observational or Manipulative? Manipulative.

We can make the conclusion that is the ecologist used the manipulative method in her research since she decided to place the turtles in two different types of ponds; one where half the ponds have predators while in the other the pond the predators have been removed. In other words, she manipulated the independent variables.

4. Hypothesis-driven? Yes!

Observational or Manipulative? Observational.

Note, the use of the word, "predicts" in most instances underscores the tone of hypothesis-driven research, hence we can say Yes! And remember, we are told the researcher "collects data", meaning he is merely observing differences that occur naturally.

5. Hypothesis-driven? No!

Observational or Manipulative? Observational.

6. Hypothesis-driven? No!

Observational or Manipulative? Observational.

MariettaO [177]

Abstract shapes that suggest plant forms or human anatomy without explicitly resembling anything nameable and allude to these natural organic forms are called Biomorphic.

These shapes may look like leaves, flowers, clouds—things that grow, flow, and move. The term biomorphic means: life-form (bio=life and morph= form). Biomorphic shapes are often rounded and irregular, unlike most geometric shapes.

Biomorphic forms are those that represent natural forms often in an abstract way, relying on contour, patterns, and textures to draw a connection to nature. This can appear in architectural or structural form, or in smaller, more decorative applications.

Three critical aspects of a description of bacterial growth are colony size, color, and shape. at least three other important fa

juin [17]

Answer:

1. Type of medium - the nutrient availability is one of the vital factors for the growth of a bacterial colony. Thus, the used growth medium will fulfill this requirement.

2. Incubation temperature - all bacteria have an optimal temperature range in which maximum growth is achieved. Any variations from this will result in negative effects on the amount of bacteria that are produced.

3. Moisture - bacteria thrive in moist or wet environments. Thus, the availability of moisture is another vital factor for the growth of the colony.
